Creating a mob

edymondo · September 1, 2014

I am having trouble with creating a custom mob, i am having the problem of nothing happening when i use the spawn egg. I think it is something to do with the model or the model class as i haven't used techne before. I am using a basic biped model.

here is all the relevant code:

Model Class

package net.mymod.Model;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.entity.Entity;
import net.minecraft.util.MathHelper;

public class ModelVampire extends ModelBase
{
  //fields
    ModelRenderer head;
    ModelRenderer body;
    ModelRenderer lleg;
    ModelRenderer rleg;
    ModelRenderer rarm;
    ModelRenderer larm;
  
  public ModelVampire()
  {
    textureWidth = 64;
    textureHeight = 64;
    
      head = new ModelRenderer(this, 0, 0);
      head.addBox(-3F, -6F, -3F, 9, 10, 10);
      head.setRotationPoint(-1.5F, -10F, -2F);
      head.setTextureSize(64, 32);
      head.mirror = true;
      setRotation(head, 0F, 0F, 0F);
      body = new ModelRenderer(this, 0, 20);
      body.addBox(-5F, 0F, -4F, 10, 15, ;
      body.setRotationPoint(0F, -6F, 0F);
      body.setTextureSize(64, 32);
      body.mirror = true;
      setRotation(body, 0F, 0F, 0F);
      lleg = new ModelRenderer(this, 16, 43);
      lleg.addBox(-2F, 0F, -2F, 4, 15, 4);
      lleg.setRotationPoint(3F, 9F, 0F);
      lleg.setTextureSize(64, 32);
      lleg.mirror = true;
      setRotation(lleg, 0F, 0F, 0F);
      rleg = new ModelRenderer(this, 0, 43);
      rleg.addBox(-2F, 0F, -2F, 4, 15, 4);
      rleg.setRotationPoint(-3F, 9F, 0F);
      rleg.setTextureSize(64, 32);
      rleg.mirror = true;
      setRotation(rleg, 0F, 0F, 0F);
      rarm = new ModelRenderer(this, 38, 24);
      rarm.addBox(0F, -1F, -2F, 5, 20, 4);
      rarm.setRotationPoint(5F, -5F, 0F);
      rarm.setTextureSize(64, 32);
      rarm.mirror = true;
      setRotation(rarm, 0F, 0F, 0F);
      larm = new ModelRenderer(this, 38, 0);
      larm.addBox(-2F, -1F, -2F, 5, 20, 4);
      larm.setRotationPoint(-8F, -5F, 0F);
      larm.setTextureSize(64, 32);
      larm.mirror = true;
      setRotation(larm, 0F, 0F, 0F);
  }
  
  public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5)
  {
    super.render(entity, f, f1, f2, f3, f4, f5);

  {
    super.setRotationAngles(f, f1, f2, f3, f4, f5, entity);
    
    this.head.rotateAngleY = f3 / (180F / (float)Math.PI);
    this.head.rotateAngleX = f4 / (180F / (float)Math.PI);
    //this.lhornang.rotateAngleY = f3 / (180F / (float)Math.PI);
    //this.lhornang.rotateAngleX = f4 / (180F / (float)Math.PI);
    //this.rhorn.rotateAngleY = f3 / (180F / (float)Math.PI);
    //this.rhorn.rotateAngleX = f4 / (180F / (float)Math.PI);

public static void registerMonsters(Class entityClass, String name) {
	int entityId = EntityRegistry.findGlobalUniqueEntityId();
	long x = name.hashCode();
	Random random = new Random(x);
	int mainColor = random.nextInt() * 16777215;
	int subColor = random.nextInt() * 16777215;

	EntityRegistry.registerGlobalEntityID(entityClass, name, entityId);
	EntityRegistry.addSpawn(entityClass, 50, 2, 4, EnumCreatureType.monster, BiomeGenBase.beach, BiomeGenBase.desert, BiomeGenBase.forest);

	EntityList.entityEggs.put(Integer.valueOf(entityId), new EntityList.EntityEggInfo(entityId, mainColor, subColor));
}
}

Main modding class (there's not much in there to do with it)

	
EntityHandler.registerMonsters(EntityVampire.class, "Vampire");

If anyone could help that would be great, i am really stuck on this. thanks

You probably got an error in you console, show it!

There are no errors in eclipse, but i hadn't thought of checking the console (good idea knokko) here is everything it says, and there do seem to be a lot of errors.

Here you go, everything from my last testing session.
