If I used partialTicks variable on drawScreen method, it won't work anymore.
But I remove the partialTicks from drawScreen and use the Minecraft.getSystemTime(); to it works.
How can I use partialTicks on drawScreen?
How to obfuscate the forge mod with proguard or something?
And how to make mod like this? I know default package is not allowed to use from other package. But OldAnimations Mod is using default package(obfuscated minecraft source) for core mod.
