How to replace a minecraft class with my own class?? or replaceing methods

ismaeel96 · July 23, 2014

hi,

im trying to make a mod, i used to be able to just edit the classes but now we cant edit the classes in the new forge gradle. i want to know how to replace a mc class with my own class and if we cant do that i want to know how to override a method in a different class?

i either have to override a whole bunch of methods or edit the class and replace the original with my own

here is how i was trying to override methods

package com.example.examplemod;

(all imports that i need)

@Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)

@SideOnly(Side.CLIENT)
public class ExampleMod extends RendererLivingEntity
{


 public static final String MODID = "examplemod";
 public static final String VERSION = "1.0";

public ExampleMod(ModelBase p_i1261_1_, float p_i1261_2_) 
        {
	super(p_i1261_1_, p_i1261_2_);
	// TODO Auto-generated constructor stub
}

    @Override
    protected void renderModel(EntityLivingBase p_77036_1_, float p_77036_2_, float p_77036_3_, float p_77036_4_, float p_77036_5_, float p_77036_6_, float p_77036_7_)
    {
       ...
    }


        // eclipse tells me to add this unimplemented method
@Override
protected ResourceLocation getEntityTexture(Entity p_110775_1_) {
	// TODO Auto-generated method stub
	return null;
}
    
}

my question is: how do i go about replaceing a whole class with my own or how to override a method that is in a mc class?

when i run eclipse MC doesnt run, i get this VVV
