Hey, so I've been reading through this http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571568-tutorial-1-6-2-changing-vanilla-without-editing

And I want to create my own coremod to change some of the 1.8 player animations back to 1.7's style, example: blockhit, sneaking, damage etc.

But I don't know how to do this for 1.8 let alone 1.6.2 if I was using it, so I was wondering if anyone can give me some help or explain it in an easier way to understand.

Thanks.

TL;DR: Don't

 

You should be able to accomplish this with the event system, although your biggest problem (regardless of what you do, codewise) is going to be doing the actual animations and rendering them.

 

But on the off-chance that the events fired are not sufficient for this, creating a coremod is a huge, huge headache.  You thought coding animations was hard?  Coding ASM is much harder.  Here's an example:

 

	private void patch(ClassNode classNode) {
	MethodNode method = ASMHelper.findMethod(classNode, "func_149674_a", VOID_TYPE, WORLD_TYPE, INT_TYPE, INT_TYPE, INT_TYPE, RANDOM_TYPE);
	InsnList patch = new InsnList();
	AbstractInsnNode absNode = findLast(RETURN, method.instructions);
	patch.add(new VarInsnNode(ALOAD, 1));
	patch.add(new VarInsnNode(ILOAD, 2));
	patch.add(new VarInsnNode(ILOAD, 3));
	patch.add(new VarInsnNode(ILOAD, 4));
	patch.add(new MethodInsnNode(INVOKESTATIC, "com/draco18s/hardlibcore/asm/HardLibPatcher", "eventFunc", getMethodDescriptor(VOID_TYPE, WORLD_TYPE, INT_TYPE, INT_TYPE, INT_TYPE)));
	method.instructions.insertBefore(absNode, patch);
}

 

I only changed the names of the methods in order to opaque the point of the patch.  Can you figure out what it does?

I have already made this mod, and all you have to do is drag it into the mc version jar and it works, I just want to know how I can get it to work with forge because I want to play with the other forge mods Ive made as well as this mod

Runtime patching with ASM (what coremods do) is different to (and a lot harder than) compiling your code with MCP and dropping the modified classes into the Minecraft JAR.

 

You'll need to have a solid understand of the Java bytecode format and the ASM library to make a coremod, neither of which you're likely to learn here or in Forge tutorials. You'll need to find your own resources.

So there isnt any other simple way to make the mod I've made work with forge?

I don't know. You may be able to subscribe to and cancel

RenderPlayerEvent.Pre

and handle the player rendering yourself, but that may conflict with other mods that do the same thing. You may also be able to use the Render Player API mod to handle your animations.

I havent made any animations, Ive just edited some of the values in several classes of the Minecraft code

Can you use events or reflection to modify these values?

I havent tried with reflection but events wont work

If it is just private field members, then use Reflection.
