Custom 3D item rendering error

chimera27 · September 2, 2013

I keep getting a null pointer exception when trying to render my item and have no idea what's causing it! Anyone know what i'm doing wrong here?

My clientproxy (The place that i'm registering the item renderer is at the very bottom)

}

And my custom renderer

package project.main.client;

import org.lwjgl.opengl.GL11;

import project.main.models.ModelPowerBeam;
import net.minecraft.entity.Entity;
import net.minecraft.item.ItemStack;
import net.minecraftforge.client.IItemRenderer;

public class ItemRenderer implements IItemRenderer {

protected ModelPowerBeam modelpowerbeam;
public ItemRenderer(){
	modelpowerbeam = new ModelPowerBeam();
}
@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {

switch(type){
case EQUIPPED: return true;
default: return false;
}
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item,
		ItemRendererHelper helper) {
	return false;
}

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {

switch(type){
case EQUIPPED:{
GL11.glPushMatrix();

modelpowerbeam.render((Entity)data[1], 0, 0, 0, 0, 0, 0.0625F);
}
default: break;
}
}

}

Also here's the null pointer exception it's throwing at me:
