SHORTTUTORIAL: DefPatches - roxxploxx/RimWorldModGuide GitHub Wiki

Zhentar's tutorial on DefPatches - Zhentar did a wonderful job on a tutorial.

There are a few additional things to be said:

---

• On else if - need a link about this
• Selecting both Defs and ThingDefs - Sometimes, your xpaths will have to modify both of these root elements. You can create an xpath that checks both of these (need someone to validate this works):

*[self::Def or self::ThingDef]/foo/bar

• On double vs single slashes - Careful about your slash use as it greatly impacts performance
  • XPath Syntax - for quick reference
