Fast Block Place Mod 1.8.9 Review

minecraft { version = "1.8.9-11.15.1.2318-1.8.9" runDir = "run" mappings = "stable_20" }

private static class PatchClickBlock extends MethodVisitor { public PatchClickBlock(MethodVisitor mv) { super(Opcodes.ASM4, mv); } fast block place mod 1.8.9

This mod removes the delay between placing blocks, allowing you to place them as fast as you can click (limited only by the server’s entity-action rate). It uses to patch the client-side PlayerControllerMP class, which is the most reliable method for 1.8.9.
