Since one of mods doesn't work, as I want (in my case: Mechanical User from Extra Utilities 2 have cooldown after each action, which doesn't work properly with redstone pulse behavior), I tried to edit that behavior.
I created same package and name of class as mod's class which I want to modify, but "edited" tile entity still have same behavior before modifying.
What I should do in that case? It's requires Coremod functionality? If ASM is possible without coremod, can I use javassist library, or I restricted to use only ObjectWeb ASM? Or even mixin can be useful?
