Mods (short for modification) are small packages that add to or otherwise affect gameplay in RimWorld. They include art packs (for reskinning the game), more weapons, more incidents, furniture, and game-balancing mods.
This page is about making mods. For info about using mods, see Installing mods.
Mod-making tutorials
Mod-making tutorials are available at the Modding Tutorials page. If you can't find what you need, you should try looking in Random Bits of Information to check if the information you're looking for has been found but just hasn't been organized into the correct article yet.
你能修改怎么
你能修改 defs, code, images（图片）, and sounds（声音）.
- Defs: XML files containing lists of definitions for use by the game. There are a lot of these. They define every thing, skills, storyteller, and many other types of data. Find them in YourModName/Defs. More about this later.
- Code: You can add .NET assemblies and the game will load them. Place your DLLs in YourModName/Assemblies. More about this later.
- Images: You can add images.
- Sounds: You can add sound files.
The basics: Defs
The most basic kind of RimWorld modding is done by editing defs.
Definitions each define some piece of the game. Different kinds of definitions can define:
- Sound
- Weapons
- Buildings
- Plants
- Animals
- More (To be determined)
When the game runs, it collects all the definitions into pools. It then semi-randomly draws from these pools in various circumstances. It will randomly draw guns of a certain category to arm a new enemy mercenary. Or, it will randomly spawn an animal type on the edge of the map. Modding the game means adding your definitions to these pools and watching the game use them in this way.
Definitions are organized into packages. Each package is saved as a single XML file.
Groups of packages are organized into mods. A mod is a unit of interlinked functionality and content. It could be a pack of new weapons, a new animal, or a total conversion of the game. A mod will usually contain several packages of various types, as well as content like images and sounds.
The base game is defined in a single mod called Core.
Players can choose which mods to activate. In some cases, several mods can be active at once. You could use a medieval mod to replace the core mod, and add on a weapons pack created by someone else. The game will run with the medieval mod content, and also randomly spawn in weapons from the extra weapons pack.
Mod file structure
For defining new game content, XML files are used. Here is an example of the format, that applies to most of the definitions:
<?xml version="1.0" encoding="utf-8" ?>
<SomeDefs>
<SomeDef>
<defName>MyNewDefinitionOfContent</defName>
<!-- more tags will appear depending on what are you defining -->
</SomeDef>
</SomeDefs>
Remember, that the word Some must be replaced by the name of whatever are you defining. For thing it's <ThingDef>.
The RimWorld mods use the following directory structure:
┌About ├╴About.xml (Contains info about the mod) ├╴Preview.png (Image that appears above the mod info in game. Max width 600px.) │ ├Assemblies (If your mod uses any DLL files put them here) ├╴MyMod.dll │ ├Defs (Contains xml definitions of the mod) ├┬ThingDefs │├╴Things.xml │└╴Buildings.xml ├┬ResearchProjectDefs │└╴MyProjects.xml │the folder name must be specific here. Look in Core mod to see what are other names supposed to be │ ├Sounds │ ├Source ├╴MyMod.cs (Optionally, put the source code of your mod here) │ ├Strings │ ├Textures (Put any image textures here, preferably in .png format.) └┬Things ├╴MyMod_ImageA.png └╴MyMod_ImageB.png
Mod info
This is found in MODNAME/About
- The contents of About.xml are plain text. HTML Markup tags cause NullRef's.
- You can have an image for your mod. Restrict the image width to 600 pixels
Textures
These are found in MODNAME/Textures
- You can have any path you want from this point on.
- When referencing textures in your mod, using <graphicPath>, have the complete path relative to your mod, including the filename (but not the file extension). Example for the RoyalBed Testmod:
<graphicPath>Things/Building/RoyalBed</graphicPath>
Interactive "things"
A thing is anything that exists in the game world. It includes resources, races (humanoid and animal), buildings, furniture, and many others.
These are defined in MODNAME/Defs/ThingDefs
If you make a new workbench, you'll need to define a recipe for it. This is a list, so you can have many new recipes listed.
The recipes themselves are defined in: MODNAME/Defs/RecipeDefs
In here you can define what ingredients/resources are required, what can be used, and what the default recipe is.
Any new resources will need to be defined in: MODNAME/Defs/ThingDefs
Turrets
These are defined in two files in: MODNAME/Defs/ThingDefs/Buildings_Big.xml and Weapons_Guns.xml (Remember, these can be named anything)
Buildings_Big.xml defines the structure of the turret itself. For example:
<building> <turretGunDef>Gun_TurretImprovised</turretGunDef> <burstCooldownTicks>300</burstCooldownTicks> </building>
Weapons_Gun.xml defines the weapon the turret uses. Anything can be used as a weapon for turrets, including grenades.
Resources
These are defined in: MODNAME/Defs/ThingDefs/Resources.xml
Research projects
These are found in: MODNAME/Defs/ResearchProjectDefs
You can have research trees as well, where additional research projects get unlocked as you move through. This is how to add prerequisites:
<prerequisites> <li>-this is the <defName> of the prerequisite-</li> </prerequisites>
Because it's a list, you can have multiple prerequisites for a research project.
Advice
- The tilde key (` or ~) brings up the development console, which will report any errors or warnings it encounters when a mod loads or during gameplay. This is the quickest way to see what, if any, errors exist in your mod. (You don't need to turn on development mode for this.)
- Use development mode (found in the options menu) to help debug your mod, spawn items related to your mod, or fire incidents at will. (Or just mess around, if you'd like.)
The other stuff: Code, Graphics, Sound
You can find links to tutorials on the Modding Tutorials page. There's also more tutorials about the basics there, so don't miss out on that.
