I'm attempting to remove the instructions from BlockDynamicLiquid which cause a third water source to appear between two existing sources. However, I cannot get the program to run. This is the class I've written: package com.xydre.minecraft.aqua.asm; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import org.objectweb.asm.ClassReader; import org.objectweb.asm.ClassWriter; import org.objectweb.asm.tree.ClassNode; import org.objectweb.asm.tree.MethodNode; import net.minecraft.launchwrapper.IClassTransformer; public class FiniteTweak implements IClassTransformer { public static Logger logger = LogManager.getLogger("Aqua"); @Override public byte[] transform(String name, String transformedName, byte[] basicClass) { if (transformedName.equals("net.minecraft.block.BlockDynamicLiquid")) { return patchFiniteTweak(basicClass); } return basicClass; } private byte[] patchFiniteTweak(byte[] basicClass) { ClassNode classNode = new ClassNode(); ClassReader classReader = new ClassReader(basicClass); classReader.accept(classNode, 0); String methodName = "func_149674_a"; String deobfMethodName = "updateTick"; MethodNode targetMethod = null; for (MethodNode methodNode : classNode.methods) { if (methodName.equals(methodNode.name) || deobfMethodName.equals(methodNode.name)) { targetMethod = methodNode; break; } } for (int i=72; i<82; i++) { logger.info(i); targetMethod.instructions.remove(targetMethod.instructions.get(i)); } ClassWriter writer = new ClassWriter(ClassWriter.COMPUTE_MAXS | ClassWriter.COMPUTE_FRAMES); classNode.accept(writer); return writer.toByteArray(); } } And this is the output: [17:21:38] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker [17:21:38] [main/INFO] [LaunchWrapper]: Using primary tweak class name cpw.mods.fml.common.launcher.FMLTweaker [17:21:38] [main/INFO] [LaunchWrapper]: Calling tweak class cpw.mods.fml.common.launcher.FMLTweaker [17:21:38] [main/INFO] [FML]: Forge Mod Loader version 7.10.85.1230 for Minecraft 1.7.10 loading [17:21:38] [main/INFO] [FML]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_40, running on Linux:amd64:3.11.4-031104-generic, installed at /usr/lib/jvm/java-8-oracle/jre [17:21:38] [main/INFO] [FML]: Managed to load a deobfuscated Minecraft name- we are in a deobfuscated environment.
