Bon alors j'ai un peu changé de direction mais maintenant j'essaye d'ajouter un appel a une de mes méthode dans le constructeur de EntityPlayer, j'ai essayé de faire mais ça ne marche pas :
@Override
public byte[] transform(String name, String transformedName, byte[] basicClass)
{
if(name.equals("aeb") || name.equals("EntityPlayer")) {
// Par exemple ici pour l'explosion : <nom obfusqué>=agw et <nom normal>=net.minecraft.world.Explosion
//Pyrion.LOGGER.info("About to patch : " + name);
return patchEntityPlayer(name, basicClass, name.equals("aeb"));
}
return basicClass;
}
private byte[] patchEntityPlayer(String name, byte[] basicClass, boolean obf)
{
String targetMethodName = obf ? "<init>" : "<init>"; // On veut modifier la méthode explosionB
ClassNode classNode = new ClassNode();
ClassReader classReader = new ClassReader(basicClass);
ClassWriter cw = new ClassWriter(classReader, ClassWriter.COMPUTE_MAXS);
classReader.accept(classNode, ClassReader.EXPAND_FRAMES);
MethodNode mnode = ASMHelper.findMethod(classNode, targetMethodName, "(Lnet/minecraft/world/World;Lcom/mojang/authlib/GameProfile;)V"); // On récupère le contenu de la méthode
MethodVisitor mv = cw.visitMethod(Opcodes.ACC_PUBLIC, "<init>", "(Lnet/minecraft/world/World;Lcom/mojang/authlib/GameProfile;)V", null, null);
mv.visitCode();
mv.visitVarInsn(Opcodes.ALOAD, 0);
mv.visitMethodInsn(Opcodes.INVOKESPECIAL, "EntityPlayer", "<init>", "(Lnet/minecraft/world/World;Lcom/mojang/authlib/GameProfile;)V", false);
// Generate INVOKEDYNAMIC instead of NEW+INVOKESPECIAL.
// This will instantiate the target class by calling its private constructor.
// Bootstrap method is called just once to link this call site.
mv.visitInvokeDynamicInsn("invoke", "()Lfr/eno/pyrion/Pyrion;",
new Handle(Opcodes.H_INVOKESTATIC, "Pyrion", "patchInventory", "(Lnet/minecraft/entity/EntityPlayer;)V", false));
// Here we have newly constructed instance of InvokeGenerator.Target
mv.visitInsn(Opcodes.POP);
mv.visitInsn(Opcodes.RETURN);
mv.visitMaxs(0, 0);
mv.visitEnd();
cw.visitEnd();
byte[] classData = cw.toByteArray();
classNode.accept(cw);
return cw.toByteArray();
}
