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.

==About RimWorld==
RimWorld is a multi-platform game written on Unity 2019.4. However, the Unity Editor is not used for creating mods unless you are creating new shaders.

===Slightly Outdated===

* [[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 While the exact content is obsolete as you can now accomplish the same result with purely vanilla XML, it is still useful as a crash course for end-to-end mod creation and is here until newer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>
* 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].
