EngineSettings - CodenameCrew/YoshiCrafterEngine GitHub Wiki

EngineSettings contains every setting that can be changed during gameplay and in scripts. Settings changes aren't persistent, so that means every parameter you change in there will reset back to the user's value at the end of each song.

Since it'd be too long to list all parameters that can be messed with, you can check EngineSettings.hx in the source code, which contains a class named SuperCoolSettings which contains all Yoshi Engine settings that can be altered in scripts.
