Change rotation of model elements


Recommended Posts


i created a custom mob. Now my problem is, that the ears from my deer don't move when the head moves.

And so it looks kinda crazy :D


Here is my ModelDeer.java :


package zcelo.mobs;

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

public class ModelDeer extends ModelBase
    ModelRenderer Body;
    ModelRenderer leftfrontleg;
    ModelRenderer rightfrontleg;
    ModelRenderer rightbackleg;
    ModelRenderer leftbackleg;
    ModelRenderer throat;
    ModelRenderer head;
    ModelRenderer tail;
    ModelRenderer leftear;
    ModelRenderer rightear;
  public ModelDeer()
    textureWidth = 64;
    textureHeight = 32;
      Body = new ModelRenderer(this, 28, 0);
      Body.addBox(0F, 0F, 0F, 6, 5, 12);
      Body.setRotationPoint(-3F, 11F, -5F);
      Body.setTextureSize(64, 32);
      Body.mirror = true;
      setRotation(Body, 0F, 0F, 0F);
      leftfrontleg = new ModelRenderer(this, 0, 0);
      leftfrontleg.addBox(-0.5F, 0F, -1F, 1, 9, 2);
      leftfrontleg.setRotationPoint(2.4F, 15F, -3.9F);
      leftfrontleg.setTextureSize(64, 32);
      leftfrontleg.mirror = true;
      setRotation(leftfrontleg, 0F, 0F, 0F);
      rightfrontleg = new ModelRenderer(this, 0, 0);
      rightfrontleg.addBox(-0.5F, 0F, -1F, 1, 9, 2);
      rightfrontleg.setRotationPoint(-2.4F, 15F, -3.9F);
      rightfrontleg.setTextureSize(64, 32);
      rightfrontleg.mirror = true;
      setRotation(rightfrontleg, 0F, 0F, 0F);
      rightbackleg = new ModelRenderer(this, 0, 0);
      rightbackleg.addBox(-0.5F, 0F, -1F, 1, 9, 2);
      rightbackleg.setRotationPoint(-2.4F, 15F, 4.9F);
      rightbackleg.setTextureSize(64, 32);
      rightbackleg.mirror = true;
      setRotation(rightbackleg, 0F, 0F, 0F);
      leftbackleg = new ModelRenderer(this, 0, 0);
      leftbackleg.addBox(-0.5F, 0F, -1F, 1, 9, 2);
      leftbackleg.setRotationPoint(2.4F, 15F, 4.9F);
      leftbackleg.setTextureSize(64, 32);
      leftbackleg.mirror = true;
      setRotation(leftbackleg, 0F, 0F, 0F);
      throat = new ModelRenderer(this, 20, 0);
      throat.addBox(-1F, 0F, 0F, 2, 9, 2);
      throat.setRotationPoint(0F, 6F, -10F);
      throat.setTextureSize(64, 32);
      throat.mirror = true;
      setRotation(throat, 0.6320364F, 0F, 0F);
      head = new ModelRenderer(this, 46, 17);
      head.addBox(-1.5F, -3F, -5F, 3, 3, 6);
      head.setRotationPoint(0F, 6F, -8.5F);
      head.setTextureSize(64, 32);
      head.mirror = true;
      setRotation(head, 0F, 0F, 0F);
      tail = new ModelRenderer(this, 6, 0);
      tail.addBox(-0.5F, 0F, 0F, 1, 3, 1);
      tail.setRotationPoint(0F, 9F, 7F);
      tail.setTextureSize(64, 32);
      tail.mirror = true;
      setRotation(tail, -0.5205006F, 0F, 0F);
      leftear = new ModelRenderer(this, 16, 0);
      leftear.addBox(-0.5F, -3F, -0.5F, 1, 3, 1);
      leftear.setRotationPoint(0.7F, 4F, -9F);
      leftear.setTextureSize(64, 32);
      leftear.mirror = true;
      setRotation(leftear, -0.5205006F, 0F, 0F);
      rightear = new ModelRenderer(this, 15, 0);
      rightear.addBox(-0.5F, -3F, -0.5F, 1, 3, 1);
      rightear.setRotationPoint(-0.7F, 4F, -9F);
      rightear.setTextureSize(64, 32);
      rightear.mirror = true;
      setRotation(rightear, -0.5205006F, 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);
    setRotationAngles(f, f1, f2, f3, f4, f5);
  private void setRotation(ModelRenderer model, float x, float y, float z)
    model.rotateAngleX = x;
    model.rotateAngleY = y;
    model.rotateAngleZ = z;
  public void setRotationAngles(float f, float f1, float f2, float f3, float f4, float f5)
    super.setRotationAngles(f, f1, f2, f3, f4, f5, null);
    this.head.rotateAngleX = f4 / (180F / (float)Math.PI);
    this.head.rotateAngleY = f3 / (180F / (float)Math.PI);
    this.leftfrontleg.rotateAngleX = MathHelper.cos(f * 0.6662F) * 1.4F * f1;
    this.rightfrontleg.rotateAngleX = MathHelper.cos(f * 0.6662F + (float)Math.PI) * 1.4F * f1;
    this.leftbackleg.rotateAngleX = MathHelper.cos(f * 0.6662F + (float)Math.PI) * 1.4F * f1;
    this.rightbackleg.rotateAngleX = MathHelper.cos(f * 0.6662F) * 1.4F * f1;



Maybe, someone can explain me how to change the rotation of elements in my model.

What I mean is you will have to move the position of the ears around because addChild moves them to a new place so the rotation point is the same as the head. To fix it, in Techne, just move both ears' rotation points to where the head is and then move the actual model back into position.
