When a mob dies, I want this mob to spawn as an exact replica of the mob but with my own AI. This means I want it to copy the rendering function of the mob that died. In EntityDeadMob.java, when the mob is spawned, the entityToDisplay variable is set as well as the position. When I run it with this code, I get an error.

 

EntityDeadMob.java

package com.julianscode.mobloot;

import net.minecraft.entity.Entity;
import net.minecraft.entity.monster.EntityMob;
import net.minecraft.world.World;

public class EntityDeadMob extends EntityMob {
public Entity entityToDisplay;
public EntityDeadMob(World p_i1738_1_) {
	super(p_i1738_1_);
	// TODO Auto-generated constructor stub
}

}

RenderDeadMob.java

package com.julianscode.mobloot;

import cpw.mods.fml.client.registry.RenderingRegistry;
import net.minecraft.client.renderer.entity.Render;
import net.minecraft.entity.Entity;
import net.minecraft.util.ResourceLocation;
import net.minecraft.client.renderer.entity.RenderManager;

public class RenderDeadMob extends Render {

Render display;

@Override
public void doRender(Entity p_76986_1_, double p_76986_2_,
		double p_76986_4_, double p_76986_6_, float p_76986_8_,
		float p_76986_9_) {
	EntityDeadMob deadmob = (EntityDeadMob) p_76986_1_;
	this.display = RenderManager.instance.getEntityRenderObject(deadmob.entityToDisplay);
	this.display.doRender(deadmob.entityToDisplay, p_76986_2_, p_76986_4_, p_76986_6_, p_76986_8_, p_76986_9_);
}

@Override
protected ResourceLocation getEntityTexture(Entity p_110775_1_) {
	return null;
}

}

Probably yelling at other people that haven't heard of OOP and trying to reinvent the water in minecraft.

 

Oh and by the way, can this error be any clearer? Try to read your logs, it generally helps.

[/Code]

 

Basically your RenderObject or the mob you want to render is empty, most likely a case of the event not capturing the mob.

Try to see when you kill it if Event.EntityLiving.GetEntityid(); or something like that returns an id.

Cool thanks, I'll try that.
