NoClassFound Error - overwrite Chunk.class (adq.class) - Core Mod

[CreativeMD]

Hi,

i have a really difficult problem. I'm working on a core mod, but i can't patch the adq class.

I have no idea why this is happening. Every other patch works perfect.

I changed the Forge version, i tried to patch a normal chunk.class (from mcp), but it is always the same error. But if i patch the adq class directly out of the forge universal jar it works.

Can anyone help?

 

The error:

What is a base edit mod???

[CreativeMD]

Yes, it would be incompatible, but how can i do this in another way?

[CreativeMD]

How do i use this, do you have an example?

[CreativeMD]

Yes, i used this tutorial, but i have to add a field to this class, and these tutorial only shows how to patch a method.

So i have no idea how to do it and also no idea why there is an error?

[CreativeMD]

For some reason this doesn't work

 

  Reveal hidden contents

// you should know all this

ClassReader reader = new ClassReader(bytes);

ClassNode clazz = new ClassNode();

reader.accept(clazz, 0);

 

// add the field

String[] type;

clazz.fields.add(new FieldNode(Opcodes.ACC_PUBLIC, "modsGenerated", Type.getDescriptor(String[].class), null, null));

// Use Type.getObjectType("some/package/foo/SomeClass").getDescriptor() if you must not trigger class loading to prevent a cycle

 

// you should know this again

ClassWriter writer = new ClassWriter(ClassWriter.COMPUTE_FRAMES | ClassWriter.COMPUTE_MAXS);

clazz.accept(writer);

bytes = writer.toByteArray();

return bytes;

There is no error, i just forget to set the default value. Thanks for everything.
