|The Quest Editor|
The editor lets you create new worlds for The Quest. These worlds can be uploaded to the Steam Workshop where every Steam player can find and play them. You can even sell
worlds (after they have been approved). See more about this in the "Uploading to the Workshop" part.
A world for the game is a complete new set of maps which the player can go to and have adventures in. You can add new graphics, items, monsters, NPCs, quests, etc., and you can also use any existing asset from the main game. You cannot change existing things, however. Attributes, skills, in game races and the way the game plays are also unchangeable.
The editor is available on Windows. You can start it from the game (Additional Worlds/Editor button). Once started, you can create a shortcut on the desktop (Misc/Create desktop shortcut). If you'd like to create a shortcut somewhere else or start the editor in some other way, the executable is located in the same folder where the game is. (You can find where it is by right clicking the name of the game on your Library screen in Steam, selecting "Properties", then the "Local Files" tab and then the "Browse Local Files..." button.) Please note that for Workshop integration to work as far as Steam is concerned, the editor is the game. This means that you can't run the editor and the game at the same time.
To upload worlds to the Workshop, Steam must be running. If your computer has 4GB (or less) memory, it's best if you exit anything you can so that only Steam and the editor runs. If Steam is running when you use the editor, the Steam overlay will also be injected into the editor. It's usually not a problem, but if you find it troublesome, you can disable it from the game's "Properties/General" tab ("Enable the Steam overlay while in-game"). (The Steam overlay cannot be disabled programmatically (by the editor).)
The Quest is not a new game. It was first released in 2006, initially for handhelds with very limited processing power and memory. The game and editor has been updated and fixed extensively since then but limitations and peculiarities remain.
Some information on the editor and on how The Quest works is available from the original programmer:
Creating a world
In the tutorial I'll go over creating a new world for the game from scratch. I won't detail every step but I'll try to highlight anything interesting. You can inspect every finished
detail by loading the world file in the editor. (If you are reading the tutorial in the Steam Client, please right click the link, select "Copy Link Address" and paste the link into a
browser to download it.)
Let's start by creating a new world (File/New).
The world id (identification) should be something which you can easily remember and type. It'll be used in every other identification (for items, quests, etc.). It must also be unique between all worlds. (This is not something you can know in advance, but if you find out it has already been taken when you try to upload the world, you can change it.) Try to use something which is related to your world. For the tutorial world, I'll use "fish". (You can use capital letters and numbers too.) The world also needs a name. This should be memorable but not too long. It can contain spaces. I'll use "Vacation" for the tutorial. The connection setting determines which sea captain you must talk to to get to the world. The intention is that you'll use Matras for worlds which are for low level characters, especially for worlds which are intended to be played separately from the main game where you'd start a new character and go to them immediately. You can use Mithria for worlds which are supposed to be played after the main game (so characters are around level 14 at least). Of course the players can go to any installed world with any character (if they can get to the appropriate harbor). I'll use Matras for the tutorial world, because it's intended for newly created characters.
When you create a new world, you'll get a new empty dungeon map and nothing else. You can create worlds without surface maps but expansion worlds usually do contain them. Lets create them (Map/Create Surface Maps).
All surface maps are 21x21 blocks (dungeon maps are 35x35). We would like 3x2 maps for the surface, so I'll select the 4x2 option (we'll leave the last two maps as empty sea). The base id for surface maps needs to be set. I'll use "fish_s" (it could be "fish_surface", but that's unnecessarily long).
As you can see, all maps must have a unique id (surface maps will have ids like "fish_s0101", "fish_s0102" etc.). This is true of everything. However, different kinds of things (like items or quests) can have the same id, ids must only be unique within a kind. There is only one exception, images and sounds cannot have the same id. Usually you'll not have to think about it, just give things an id you like, the editor will tell you if the id is already in use. When adding external files like images or sounds, the editor will also suggest an id.
Let's finish up the surface maps. We'll select "bres_water" as the background type (because the world will be a small island). You can use everything from the base game (this includes things with "bres" and "base" id). After you have created the surface maps you'll find yourself in the top left map, which is all empty sea.
Blocks in The Quest have the following structure. First, there is the floor. It has a default image (texture) for the whole map. You can put two extra layers on top with different images.
You use the "[Floor] Floor" menu to select what to put on the first layer and the "[Floor] Road" menu to select the image for the second layer. You can change the default image with
the "_set: default floor" menu. You can put extra "decoration" on top of these three layers with the "[Floor] Floor decoration" menu. On top of the floor comes either walls or objects
(like trees, monsters, etc.). A wall completely fills a block. You can put down walls with the "[Wall] wall" menu. There are actually two levels where you can put walls. The ground level
and the "high" level. This way you can create taller structures. You can also change the "floor" of the high level (this will be the ceiling of the ground level) and put most of the
objects you can put on the ground level on the high level too. To select which level you work on, click the appropriate button after the "Level:" text in the main window.
After you've added walls, you can put roofs on them with the "[Wall roof (on a wall)" menu (on the second level too). To select a block to modify, click on it or use the arrow keys to move the selection. Use the "space" key to place the currently selected object type.
One large part of creating maps for The Quest is placing all the objects (walls, trees, etc.). The other large part is defining their functions by setting their properties and adding scripts. A lot of the properties are self evident, but I'll return to this part later.
I'll use a "trick" for the surface maps of the tutorial. For the first 3x2 maps, I'll change the default floor to "Grass01".
Because the maps are not water for the most parts, it would be a waste of a floor layer to leave the default on water (and would make it difficult, if not impossible to add both swaths of different textures and roads on top). After I've changed the default floor, I'll add back the water on the perimeter of the landmass to achieve a natural look. I'll simply use the "floor" layer and add water to the outlying blocks. When adding floor layers, you must select a "mask" to apply. This will determine how to layers blend together. I'll use the "Shoremask" for the sea and the "Roadmask" for roads. You can experiment with all mask types (and you can even add your own, but that's quite involved, all 47 mask images must be added together). One more thing. You'll need at least two blocks of water to prevent the player going over such blocks. If you check the world, you'll see that I used at least two blocks of water everywhere around the island.
In the tutorial world, I'll put a village in the top right map of the island and a mound in the bottom right. I want to leave the two top left maps as grass/forest. I'll not really use the two bottom left maps. So I'll add hills to them to add ambience. This can be done with the "[Block] lonely roof (w/o a wall)" menu. First I created the "skeleton" of the hills with walls (using a rock texture). Then we can add slopes with the aforementioned "roof" objects. The editor/game will auto-select which concrete 3d model to show for each block. You can influence the shape by placing roof objects appropriately. If you don't want unsightly gaps, this will constrain your placement. Look at the completed world in the editor to see the possibilities.
I've used the "Stone07" image for the slopes. If you try to select a similar looking texture for the walls, you'll find that there is no good match. The "Stone03" image seems good, but it's too bright. Let's create a new palette for it! There is a shortcut for the editing window in the form of the "Edit type" button. When you open the editing window, you'll find that most things cannot be changed, because this is a base resource wall type. However, we can add new palettes for base resources too! I've named the palette "dark".
The id is automatically created. A palette consists of three "modifiers", which are applied one after the other to the image, in real time, when the palettized image is drawn. This means it's better to use as few modifiers as possible. (When you create a new palette only the first modifier is active.) A modifier works by selecting a "hue range" with the first control (the two downwards pointing triangles over the color bar) and modifying the selected colors with the hue/saturation/brightness controls. For the "dark" palette, I used 10 hue, -24 saturation and -7 brightness (I haven't changed the color selection, so the modifier is applied to all colors).
This palettization (especially with more than one active modifier) is quite flexible, but you might have to experiment a bit to get the desired result. The palettization cannot really "add" colors (only change them), so you might find that the less colorful (more gray) an image initially is, the harder to change its colors.
After adding the hills, I've also added a "mound" in the bottom right surface map the same way. This will be the entrance to the crypt of the evil warlock, who is the main interest in the world. Next I've added trees, bushes and flowers/mushrooms on lots of blocks to create a forested look. I've also added darker patches of grass and ground as extra floor layers here and there. You can add add "foresty" stuff using the "[Forest] ..." menus. There is also a special "[Group] group of objects" menu. With this you can add more than one of the same thing to a block. To change how many are added, use the "Density" option. Placement will be random. To guide the player, I've left the way I'd like them to go mostly empty and also added roads. These are quite patchy, because this is not a well developed place.
To finish the main features on the map, I've created a small village. This involves two things. The first is putting in houses, using the walls and roofs. The second is putting decorations on the houses. Doors and windows count as "decorations" in this case. Until know I put things on blocks. A lot of things can only be put on walls. This not only includes things which obviously go on walls, like doors, but things which go beside walls too, like barrels. Everything in the "[City] city door", "[City] city sign", "[City] city window", "[Item] container", "[Item] shelf", "[Npc] npc/wall", "[Switch] secret switch", "[Wall] wall decor" and "[Wall] wall line" menus goes on a wall. The "[Switch] lever" menu is also special. The floor switch goes on the floor but "Lever02" goes on walls. To place things on walls, use SHIFT + click to select one of the four sides of a block. (You might need a little practice at first. :)
After I've added everything to the surface maps, I've named them. This can be done in the "Map/Map Properties" dialog. Maps must have different ids but they can have the same name. (There is no need to name every empty water map differently. I've named them "Sea".) You can select different surface maps either by moving outside their boundaries, in which case the neighboring map will be selected, or you can click on the buttons beside the "Surface:" text in the main window.
The map button brings up the world map dialog. You can double click a part to select the relevant map. This is also the place to generate the in-game map image. You can do this at any time with the "Regenerate" button, but it should be done at least once when you've finished creating the surface maps.
Time to create the dungeons. One dungeon map already exists ("fish_newmap"). First rename it to something more descriptive. We'll also rename the id. It'll be the home of our evil warlock, so we'll name it "Crypt" and it's id will be "fish_crypt". I'll not only change the default floor, but the ceiling too. This can be done in the "_set: ceiling" menu. This only works in dungeon maps. This sets the second level ceiling. The first level ceiling is actually the "floor" of the second level and will use the default floor image when we place a wall on the second level. This means we have to replace the ceiling on each block where we don't want the default floor as ceiling.
Placing walls should be familiar by now. There a few new things though. I've used doors. These can be found in the "[Block] dungeon door" menu. There is a sufficient "darkgreen" palette already for the door frames, but I've added a "green" palette for the portcullis.
After placement, I've used the "Edit" button in the bottom left part of the editor window to change the settings for the doors. This works for all things on the map. I've also added wall blocks on the second level over most of the dungeon, to limit the height to one block. As mentioned before, you'll have to place new floor (from the "[Floor] floor" menu) over these blocks if you are not satisfied with the default one. I've left the central room at two blocks height to make it more impressive. I've also added a chasm around the central room by using the "[Floor] big hole" menu. There is also a stairway leading down. It can be found in the "[Block] dungeon door" menu (Stair01).
The stair leads to another level of the crypt. We can create it with the "Map/New Map" menu option. You don't have to worry about lining up the stairway on this map and the stairway on the main crypt level. Moving between levels is handled by using objects with ids and those objects can be anywhere. Crypt Level 2 is a small map with only the sphere in the back the only new thing. (We also need a new map for the inn's interior.)
People, monsters and other things
After creating the maps, it's time to populate them. First let's place the point where you arrive into the expansion.
This will be a specially named object, called "fish_STARTGAME". This can be any object, but usually it's best to actually place a position for it. A "position" is something which doesn't
have an associated graphical representation, but can be placed in a block like other things (it's in the "[Position] position" menu). After placement, we can edit it. It already has an
object, but it's unnamed. Let's rename it to "fish_STARTGAME" and set the direction to east. We'll be adding the script later.
The story is that you are on a vacation and you'd like to rent a fishing boat so you've come to this small island with a fishing village. However, as you get near the village you discover that all the villagers are wandering about outside, frightened. As it turns out an evil warlock was disturbed in its crypt nearby, turned the innkeeper into a ghost and chased the villagers out. The real reason the warlock got up and about is the village alchemist who stole a book from the crypt. Your quest on the island is to solve the warlock problem. There are three possible ways to do it. The best is to find out all you can and pressure the alchemist into admitting what he has done. He'll then give you the stolen book which you can put back into the crypt. The warlock will be pleased and you can go back to the happy villagers. If you don't get the book or don't put it back, you can still get the good ending, by exploring the crypt and destroying his power sphere before confronting the warlock. In that case he'll try to curse you and the villagers but will fail. After you've killed him, you can go back to the happy ending. If you confront the warlock without either putting back the book or destroying the sphere, he'll curse you (making the fight harder) and the villagers, turning them into ghosts. You must then kill them too to finish your adventures on the island. In either case, after you've done everything, you'll find that the ship captain who brought you here has returned and you can leave the island.
To simulate the different phases of the quest, we'll add all possible people/monsters but hide those who are not relevant at first. To create monsters/people we'll need a few different things. First, in The Quest monsters/people roaming about and people who you can talk to are different things. To place "monsters" (including people) we can use the "[Monster] ..." and "[Npc] ..." menus. These can be created in the "World/Manage Monster Types" dialog. All monster types have a "base monster type" (which can be created in the World/Advanced/Manage Base Monster Type" dialog). Characters you can talk to can be created in the "World/Manage NPC Types" dialog. You can connect an npc to any monster type (which is placed on the map), but you don't have to. If you create a monster type without an npc, you'll not be able to talk to it. But for a real monster it's usually not needed, you'll set it as aggressive and the player can fight it. You can also connect an npc to a door, for example. In that case it'll not have a body in the world but you can still talk to it.
So, lets place people. In the glade west of the village, I placed a few wandering villagers, men, women and children. For this I've created three npcs and three "monster" types (based on the appropriate villager base monster type). There are more than three villagers ambling about, but all the men, all the women and all the children can be the same "person" (npc), because all they do is provide some information. To see what they do, let's edit one of them (Edit button on the main window). First note that all of them have a named object. By default, freshly placed monsters don't have one, so I've created one for each using this dialog and named them.
An "object" is something the game uses to keep track of the state of things. An object can be on/off, visible/hidden and has a "state" variable. All of these can be accessed from scripts. This is why I've added named objects to each wandering villager, to be able to control their visibility from a script. If we click on the "Edit this type" button, we bring up the "monster type" dialog. There are two of these, one for genuine monsters and one for people ("city npcs"). This dialog can also be accessed from the "World/Manage Monster Types" dialog, in fact it was there where I created them. We can change a few properties here but we are more interested in the speech dialogs of the npc which is connected to this city npc ("monster") type. It can be accessed from here with the "Edit NPC" button or from the "World/Manage Npc types" menu.
For now we are interested in the dialogs of the npcs. So bring them up with the "DIALOGS" button.
Let's take a look at the dialogs of a wandering fisherman. On the left you can select either their greetings or their conversation topics. When you talk to an npc, the game will first select a greeting from the list. The game will select the first greeting and the first topic from that greeting which satisfies all prerequisites. (If there are no greetings or no greeting is selected, you'll see a "(no response)" text.) In case of our fisherman, all its greetings and topics are shared. Shared dialogs can be edited in the "World/Advanced/Shared Dialogs" dialog. (It might be a little confusing, but yes, both the window to edit things and the speech topics/greetings are called "dialog".) You can see that there are two greetings for a fisherman. The first will be selected if the global variable "fish_warlockgone" is equal to 1, while the second if it is equal to 0. In the second case there are three topics within the greeting and all have their own extra conditions. Which in this case will result in selecting one of the tree at random. To find out what the different conditions mean, please see The Quest System PDF.
One of the fisherman is the Elder Fisherman. He has his own quest, so he has his own monster type and npc. He also stands in place near the center of the map, to be easy to be found. You can ask him the same question you can ask the other people around, however, instead of answering, he'll give you a quest. You can create quests in the "World/Manage quests" dialog.
It's time we take a look at scripting. Scripts can run in three different places in the game.
First, they can run after every response (speech) an npc gives. They can be edited in the dialog editor window. These are frequently used to keep track of quest states or give to or take
from the player some item (or money).
Second, scripts can run in response to an event (the player arriving somewhere, stepping on a block, using or hitting something, a monster dying, etc.). They are attached to monsters/npcs or other map objects like doors and can be edited alongside with other properties of those map objects.
Finally, scripts can also run after a page of text has been displayed in a "scene" (cutscene). The last two kinds of scripts can be reused by different objects and can be edited independently from them, from the "World/Manage Scripts" window.
The Quest uses its own script. It looks and behaves like C, with some (large) differences. The basic syntax is the same. You write statements terminated by the semicolon (
One large difference from C is that there are 'objects' on which you can call functions just like in C++. I've talked about them a few paragraphs back. It can be a little confusing, because there are different 'objects' which you can place on the map (for example walls, trees, etc. these are all called 'map objects') and there is the special 'object' which can be attached to 'map objects', monsters, etc. This 'object' is basically a struct from C, with data members. As I've written, it holds some state (on/off, visible/invisible and a state variable which starts out as
Globals and object state (including the player's, of course) is saved into the save file, so it's preserved. Local variables behave like in C, they disappear after their block has been executed. For object access, a convenient shortcut is available. Apart from scene scripts, all scripts run in the context of an object. Dialog scripts run in the context of the npc object and map object scripts run in the context of the map object (or monster). This means there is an implicit "current" (or "this") object and you can use it without writing its id. For example, in a dialog script you can write
Generally you can refer to objects not yet created while you write scripts, but it's best to create all objects (and globals) before referring to them.
There are some peculiarities (limitations) to the quest script on top of the already mentioned ones.
Now on to the other half of this quest. I've created an innkeeper npc and an innkeeper "monster". I've connected the npc to the monster type and put an instance of it into the inn map. I've also created (and named) an object for this monster to keep track of its state. The topic to get some rum from him is called "Rum". The only response has the condition "PCQuestReceived fish_rum > 0", which means it'll only be displayed if the player has gotten this quest (remember anything not
The script on the inn's door is also interesting.
Scripts run on map objects (like this door) and monsters/npcs are usually run in response to events, like using or hitting the object (or monster). When editing a map object (or monster) the editor will display which events can happen on it ("Possible events"). For this door, we are interested in the "use" event. So the script checks if the door is being used (
There is one last
Astute observers can note that I haven't talked about yet another
At this point a small explanation is required. When we first created The Quest, I (Elendil) was only responsible for the graphics engine. The majority of the code, including the game systems and scripting were created by Stewe. He, however, has left us a long time ago. Since that time I've fixed countless bugs, added and modified things and ported the game to lots of platforms (iOS, Steam, Mac, Android). Still, I wouldn't say I understand the game completely. The code is ... convoluted. :) In any case, although The Quest script is not perfect, lots of things can be done with it. Experiment, look up how things are done in either the tutorial world or the main world and if all else fails, ask in the forums!
Let's take a look at the dialogs of the alchemist! First, it's using the usual state handling, with separate phases of his quest handled by increasing state values. There is something new here, however. On the very first response, there are answers. When a response is selected and displayed, if there are answers defined for it, they will be displayed after so the player can select one. Answers have their own condition (only one) and they are only displayed if it's true. The "Always" condition (as can be guessed) is always true. After the player selected an answer, the game will continue with the topic, which means it'll check the following responses and select the first for which all conditions are true. This way we can make the alchemist react appropriately to the answer the player selected. (One additional note: the
To enter a different map, we don't need to create a script, but we can. We have seen that case with the inn entrance. Let's take a look at the crypt entrance! It's the hole in the wall on the south side of the mound on the "Warlock's Mound" map. If we edit this object, we can see that it has a "Target". If we use this object (by clicking on it or moving into it), it'll transport us to its target. If we leave the question empty, this will happen automatically. If not, like here, the game will ask a yes/no question and only transport us when we answer "yes". The "fish_cryptin" object is on the "fish_crypt" map. There are a group of rocks at the south end of the crypt, beside a similar hole. They have the "fish_cryptin" object, so entering the crypt will put us here. As we can see, we can go to any object, not just to positions (like in the case of the inn or the arrival point for the world). The only downside is that we cannot set a direction, but we already set up both maps so that it's not needed. There is another peculiarity with this particular arrival point. It has a script.
We would like to light up the torches beside the warlock's book stand when the player puts back the book. However, the torches are lit ("on") by default and the editing window for them doesn't let us turn them off. So we use this script to turn them off, but only when the book hasn't been placed yet.
If we don't put back the book, we can still achieve the good ending by destroying the warlock's sphere before talking with him. The sphere is on its own level so we set the stairs on this level to go down there and the stairs on that level to come up here. These use positions as their targets and also set the direction so everything will feel natural. This is the way that map transitions are done usually.
The second door on level two of the crypt is magically locked (so it cannot be picked), just like the entrance door inside the crypt on the first level. The key for this door (on level two) is held by one of the Gargoyles. To achieve this, I've create two identical monster types, with one having the key and the other don't (and of course I've placed one instance of each on the map). After we have dispatched the gargoyles and entered the sphere room, we can use any available means to destroy the sphere (the script will run on hit, use or spell use).
Adding new images
For demonstration purposes, I've created a new base monster type, with its own graphics. The graphics (and sound effects) are from the Islands of Ice and Fire expansion.
Creating a new base monster type is mostly self explanatory, but please note that palette creating can be accessed from the monster type window and not from the base monster type window (even though palettes are for the graphics in the base monster type). Also when you first create a new base monster type, you can't set the paralyzed palette (as there aren't any yet), but even though the window won't show it, it'll use the "default" palette (which is no color change at all). After you've created a new monster type which uses this base monster type and created palettes there, you can come back to the base monster type window and set a different paralyzed palette.
A note on the monster walk cycle. Step 1 to 8 constitutes a full walk cycle, however step 7 is the start (the standing frame). Step 8 is when the monster starts to bring its left foot (on the right side of the image) forward and the animation continues with step 1, etc. The idling frames are step 7, then step 1, then step 7 again and then step 5.
Creating other new map object types or base item types works similarly.
The Quest editor accepts two kinds of images. 24 bit true color BMPs for things which are not transparent (like floor or wall images) and 32 bit true color BMPs with alpha channels for things which are transparent (like monsters, trees or decorations). These should be plain BMPs, without additional metadata (like color space information). Most image manipulation programs by default will create BMPs which have the appropriate format. Apart from this, there is only one requirement: all images must have widths and heights which are divisible by 4 (so the images can be compressed when exported for use by the game).
For non-transparent images, if you get BMPs or convert from other formats the resulting files will more than likely work. For transparent images, you might need to do some work. One frequently used format for transparent images is transparent PNGs. The Quest editor cannot use these, but they can be easily converted to 32 bit transparent BMPs. I'll detail here how to convert them using Photoshop. To create correct transparency and prevent color fringes, colors must be propagated to the transparent pixels. There is a freely available Photoshop plugin which can be used for this purpose. It's called "Solidify B". It's available here.
Back to the warlock. He starts out peaceful but can become aggressive so we check for that. (You can talk to aggressive npcs in game.) We also check if the book was put back or the sphere
was smashed so we can select the appropriate response. If he becomes aggressive, he'll close the portcullises (which will be raised when he dies).
In his map object script we must always call the
After we solved the warlock problem, we can go back to the village. On the road there we can run a script to get to the final parts of the quest. I've made sure this is the only way to get back to the village so the script will always trigger. I used the usual
You might have noticed that on the "Glade" map there are many positions placed with a similar script to move the plot along. I've used all those positions to run the same script no matter where the player enters the map. I could have used the same technique of restricting the map to only have one entrance from the west but I thought it wouldn't look that good.
After the script on the road coming back from the warlock has run, the world is close to finished. You either have to kill all the ghosts or you can talk to the grateful villagers. In any case, there is nothing else to do after this than go back to Freymore. The captain (and his ship) has already been made visible so we can talk to him. His script has another special construct.
Having completed our world, it's time to test it! This is very important, it's almost guaranteed that you'll not get everything right the first time and you'll need to change and fix things.
To test your world, first select "File/Export for PC/mac". This will create a ".pak" file usable by the game. By default, the editor will export the file into the appropriate folder. (It's
"Documents/The Quest/expansions". If you've exported the world somewhere else, copy the exported file into this folder.) To actually test the world, exit the editor and start the game.
In the case of the tutorial world, after starting a new character and going to Captain Verra we should see a new travel destination, called "Vacation".
Testing is very important, but it can be tricky. When a character is in a world the game saves lots of information about that world. The items collected, monsters killed, etc. This means that it can be problematic to load a save when you've changed the world. The game will load some things from the world and some things from the save file. This can lead to many problems and even to crashes. One particular problem experienced many times by expansion creators happens when they add new shops to an existing world. If a character which was near to the new shop goes there it might happen that all the items in the shop get dumped somewhere on the map. This (and similar things) can be prevented by waiting at least a week (in game time) on a different map. This is because things in the world get reset after one week in game has passed, which clears out the saved data for that map. The best might be to wait somewhere on Freymore, completely outside the new world.
Unfortunately some problems are not prevented even by this. To be sure that everything works as intended, the new world must be restarted for a proper testing. This can mean a completely new character for low level worlds but an existing high level character is just as good (for high level worlds), just make sure you (or your testers) load a save which has never been to the new world.
Uploading to the Workshop
If everything is finished and tested, it's time to upload the world to the Steam Workshop! Just save your world (Ctrl + S) then select the "File / Upload to Steam Workshop" menu item.
By default, your uploaded world can be freely downloaded and played by anyone. If you think your world is high enough quality and you'd like to sell it, you can tick the "I would like to sell this world" checkbox when you first upload it. Please note that this will not make the world available for buying automatically. This will only put the world into the "Curated" section of the Workshop, where people can vote on it. This voting is only for us (Redshift) to gauge the interest in worlds uploaded with intent to sell and is a standard feature of the Steam Workshop. However, we strongly recommend you contact us even before you upload your world if you'd like to sell it. We'll have to take a look at it ourselves and decide if we wanted it to be sold or not. There is of course no guarantee that your world will be selected. Before uploading, you have to exercise your judgment. Compare your world to the main game, to the Island of Ice and Fire DLC and to any already released paid world. It doesn't necessarily have to be as large and complex as them but it should be well developed, good looking, without bugs and interesting enough.
You can change the name and description of a world any time. Either when uploading a change or on the Steam Workshop page. The preview image can only be changed by setting it here in the upload window. It's best if the preview image is square but that's not strictly necessary. After you've uploaded a world you can add additional images (screenshots) on the Workshop page. The visibility is "Public" by default but if you don't want to release your world to everyone at first, you can change it. (It can also be changed at any time on the Workshop page.)
Finally, something very important. Please refrain from uploading worlds with objectionable content (overly gross or violent or with sexually explicit images, etc.) or content taken from other copyrighted works (games, books, films, etc.). Problematic worlds will be deleted/hidden and their creators may be banned. If in doubt, please ask on the forums.
