It works on the dev environment. But crashes upon loading on the client.

And why is that? The block needs to fall after all...

My coremod works perfectly in the dev environment, but not in the actual client.

Thank you so much! It works!

Scratch that, now the method is found but not run. public class CppClassTransformer implements IClassTransformer { @Override public byte[] transform(String className, String string, byte[] bytes) { if (className.equals("atr")) return transformBlock(bytes, true); if (className.equals("net.minecraft.block.Block")) return transformBlock(bytes, false); return bytes; } private byte[] transformBlock(byte[] bytes, boolean obfuscated) { String targetMethodName = obfuscated ? "func_176213_c" : "onBlockAdded"; ClassNode classNode = new ClassNode(); ClassReader classReader = new ClassReader(bytes); classReader.accept(classNode, 0); for (MethodNode methodNode : classNode.methods) { if (methodNode.name.equals(targetMethodName)) { System.out.println("Found method!"); InsnList injectionList = new InsnList(); injectionList.add(new VarInsnNode(Opcodes.ALOAD, 1)); injectionList.add(new VarInsnNode(Opcodes.ALOAD, 2)); injectionList.add(new VarInsnNode(Opcodes.ALOAD, 3)); injectionList.add(new VarInsnNode(Opcodes.ALOAD, 0)); injectionList.add(new MethodInsnNode(Opcodes.INVOKESTATIC, "io/github/anon10w1z/craftPP/CppClassTransformer", "onBlockAdded", "(Lnet/minecraft/world/World;Lnet/minecraft/util/BlockPos;Lnet/minecraft/block/state/IBlockState;Lnet/minecraft/block/Block;)V")); methodNode.instructions.add(injectionList); } } ClassWriter writer = new ClassWriter(ClassWriter.COMPUTE_MAXS | ClassWriter.COMPUTE_FRAMES); classNode.accept(writer); return writer.toByteArray(); } @SuppressWarnings("unused") public static void onBlockAdded(World world, BlockPos blockPos, IBlockState blockState, Block block) { if (CppConfigHandler.additionalFallingBlocks.contains(block)) world.scheduleUpdate(blockPos, block, block.tickRate(world)); System.out.println("Hai"); } } "Found method!" is printed but "Hai" is not when the block is placed. EDIT: Forgot the return. Testing with it now EDIT2: No dice.

onBlockAdded does nothing. By clearing the instruction list anyways you destroy any hooks that another coremod might have put there. In bytecode there is always a return instruction. Loading the values on the stack before calling your method. You should really dig deeper in understanding how bytecode works before making a coremod. Thanks for the advice, I'll do my googling. But why is it still crashing?

I'm overriding the whole method functionality, and the method doesn't return a value. EDIT: Now it doesn't crash, but how can I pass the parameters from the vanilla method to my delegate method? EDIT2: It turns out it didn't find the method in the first place. When I fixed that issue it crashed.

The actual error is that the Block class is not loaded.

If possible, is there a way to change the subclass of a vanilla class, e.g. make BlockDirt subclass BlockFalling?

That is a thing that takes ~5-10 minutes using pure ASM. No need to throw a huge library at it. This is a horrible idea but can be done without any base edits. Alright then I'll ditch Byte Buddy

I'm trying to make dirt and clay fall like sand, and change the getItemByText and getBlockByText methods in CommandBase to allow using items and blocks by ID in commands.

My Byte Buddy code works perfectly in the development environment, but for the compiled mod it doesn't seem to work. String blockClassName = deobfuscated ? Block.class.getName() : "atr"; installMethodInterceptor(blockClassName, named(onBlockAddedName).or(named(onNeighborBlockChangeName)).or(named(updateTickName)).or(named(tickRateName)), CppBlockInterceptor.class); String commandBaseClassName = deobfuscated ? CommandBase.class.getName() : "z"; installMethodInterceptor(commandBaseClassName, returns(Item.class).or(returns(Block.class)), CppCommandInterceptor.class); private static void installMethodInterceptor(String methodContainerName, ElementMatcher<? super MethodDescription> methodMatcher, Class methodInterceptor) { try { Class methodContainer = Class.forName(methodContainerName); new ByteBuddy().redefine(methodContainer).method(methodMatcher).intercept(MethodDelegation.to(methodInterceptor)).make().load(methodContainer.getClassLoader(), ClassReloadingStrategy.fromInstalledAgent()); } catch (Exception e) { e.printStackTrace(); } } And this fails with a ClassNotFoundException for the obfuscated class names. Shouldn't they have been obfuscated since it's not in a development environment?

The event is fired for every element on every frame. Since your rendering only needs to happen once per frame, you pick the proper element type. For example the experience bar element rendering only happens in survival mode.

Take your super.onUpdate call outside the world.isRemote check. That should fix it.

BlockEvent.BreakEvent. When the block is broken, check the harvest level of the player's held item. If it is below the normal requirement, drop the diamond. You can also modify the amount of XP dropped.

These are the Forge forums...

This is part of a method called from my event handler. I'll try the .copy() method out. UPDATE: Worked like a charm! Thanks.

In 1.8 I use an event handler to add functionality for an automatic smelting enchantment. if (player != null && !player.capabilities.isCreativeMode && EnchantmentHelper.getEnchantmentLevel(this.effectId, player.getHeldItem()) > 0) { HarvestDropsEvent event = (HarvestDropsEvent) baseEvent; ItemStack drop = event.drops.size() == 0 ? null : event.drops.get(0); if (drop != null) { ItemStack smeltStack = new ItemStack(drop.getItem(), 1, drop.getMetadata()); ItemStack smeltResult = FurnaceRecipes.instance().getSmeltingResult(smeltStack); if (smeltResult != null) { smeltResult.stackSize *= drop.stackSize; event.drops.clear(); event.drops.add(smeltResult); } } } This code works only the first time breaking a certain block. After that, nothing drops. For example, the first time breaking an iron ore yielded one iron ingot. Tries after that all yielded nothing. This is done using the HarvestDropsEvent.

Alright I figured it out, first get the list of ore IDs for the stack, stream them and map them to their corresponding name. Thanks for the help guys.

I want to do it the other way around. From an ore dictionary recipe, get the inputs as strings. And my mod is unique,

And what do you want to tell us with that? He's using that as his reasoning for having bad variable names

I want to determine the inputs, as strings, from an OreDictionary recipe. For example, for an iron pickaxe get the inputs as: ["ingotIron", "ingotIron", "ingotIron", "null", "stickWood", "null", "null", "stickWood", "null"]

That's unfortunate. Thanks for helping.

I'm writing a mod to write certain fields of items and blocks to Json files, using the library json-io. I have to specify the fields I want outputted to the library.

I need to figure out the obfuscated name of several (10+) fields in vanilla classes. I attempted to use the FMLDeobfuscationRemapper to do this, but unfortunately it returns an empty map. try { Method getFieldMapMethod = FMLDeobfuscatingRemapper.class.getDeclaredMethod("getFieldMap", String.class); getFieldMapMethod.setAccessible(true); Map<String, String> itemFieldMap = (Map<String, String>) getFieldMapMethod.invoke(FMLDeobfuscatingRemapper.INSTANCE, "net.minecraft.item.Item"); System.out.println(itemFieldMap.keySet()); } catch (Exception e) { e.printStackTrace(); } This prints out [].
