This is the table of contents for the modding tutorial. Here, you'll learn step by step how to create mods of gradually increasing complexity.
+
This is the hub page for tutorials, guides, and reference materials for creating mods for RimWorld. If you are looking for instructions on how to use RimWorld, please check out the general [[Modding]] hub.

In light of little official documentation, most of the knowledge here was gained by experience, trial-and-error, decompiling and learning from the source. Keep in mind that RimWorld is a big game that underwent substantial code changes during its alphas. While most of this wiki was updated for 1.0, some information you find may be outdated.  
+
As RimWorld does not have a formal modding API, nearly all of the information here has been gathered and maintained by the modding community.

 +
* [[Modding_Tutorials/Plague_Gun_(1.1)|Plague Gun]] - This tutorial was created for RimWorld 1.0 but updated for 1.4. While the exact content is obsolete as you can now accomplish the same result with purely vanilla XML, it is still useful as a crash course for end-to-end mod creation and is here until newer tutorials can replace it.
 +
 
 +
===Uploading to Steam Workshop===
 +
* You can upload your mod to Steam Workshop by enabling Development Mode from your game Options and then using the Upload option under the Advanced button in the vanilla mod manager.
 +
* Note that in order to upload to Steam Workshop, you must own the game on Steam Workshop. Owning RimWorld on GOG or Epic will not work.
 +
* Your Preview.png should be a 640x360 or 1280x720 PNG and '''must''' be under 1MB. If it is too large, then your upload will be rejected with <code>Error : Limit Exceeded</code>
 +
* If you get a <code>OnItemSubmitted Fail</code> error, this usually means that Steam Workshop is having some technical issues at the moment. If it keeps occurring, then the only thing to do is to wait a few hours for it to clear up.
 +
* Steam mod descriptions don't use markdown, they use a variant of BBCode. Please check out the [https://steamcommunity.com/comment/Guide/formattinghelp Steam text formatting guide].

==What's a mod?==
+
'''Note:''' All of the above tutorials have been cleaned up and reviewed by the #mod-development team on the [https://discord.gg/rimworld RimWorld Discord] in cooperation with RimWorld Wiki staff editors. Please let us know before creating, adding, or making any major edits to the vetted tutorials and guides section!

A mod is a folder containing data the game reads/loads. Mods can add, remove or alter the content of other mods (including the Core mod) in the broadest sense of the word. For more info, see also [[Modding]].

This is the hub page for tutorials, guides, and reference materials for creating mods for RimWorld. If you are looking for instructions on how to use RimWorld, please check out the general Modding hub.

As RimWorld does not have a formal modding API, nearly all of the information here has been gathered and maintained by the modding community.

NEW: RimWorld 1.5 Mod_Updates - A work-in-progress list of changes datamined by the modding community in the current unstable version of RimWorld 1.5. THERE MAY BE ANOMALY SPOILERS, YOU HAVE BEEN WARNED.

Uploading to Steam Workshop[edit]

  • You can upload your mod to Steam Workshop by enabling Development Mode from your game Options and then using the Upload option under the Advanced button in the vanilla mod manager.
  • Note that in order to upload to Steam Workshop, you must own the game on Steam Workshop. Owning RimWorld on GOG or Epic will not work.

  • If you get a OnItemSubmitted Fail error, this usually means that Steam Workshop is having some technical issues at the moment. If it keeps occurring, then the only thing to do is to wait a few hours for it to clear up.
  • Steam mod descriptions don't use markdown, they use a variant of BBCode. Please check out the Steam text formatting guide.
