This guide is for modders who write or port script mods for The Witcher 3 Remastered (patch 5.01; the game's own files number it 4.10, and this guide says Remastered). It assumes you can read WitcherScript and have installed a mod by hand. It does not teach the language.
Remastered lets a mod change one method or add one field with an annotation (@wrapMethod, @replaceMethod, @addMethod, @addField) instead of shipping a whole copy of a game file. Annotations cover most script modding, but not all of it, and the gaps show up only at compile time. This guide gives the rules, the exact compiler message that reveals each one, and a workaround where one exists.
