You are using a corrupted model from techne, that's not your fault but techne creates corrupted files, you can correct your file here : http://scarex.fr/model_corrector.php.

 

For the animation, I found this :

/**
     * Used for easily adding entity-dependent animations. The second and third float params here are the same second
     * and third as in the setRotationAngles method.
     */
    public void setLivingAnimations(EntityLivingBase p_78086_1_, float p_78086_2_, float p_78086_3_, float p_78086_4_)
    {
        EntityIronGolem entityirongolem = (EntityIronGolem)p_78086_1_;
        int i = entityirongolem.getAttackTimer();

        if (i > 0)
        {
            this.ironGolemRightArm.rotateAngleX = -2.0F + 1.5F * this.func_78172_a((float)i - p_78086_4_, 10.0F);
            this.ironGolemLeftArm.rotateAngleX = -2.0F + 1.5F * this.func_78172_a((float)i - p_78086_4_, 10.0F);
        }
        else
        {
            int j = entityirongolem.getHoldRoseTick();

            if (j > 0)
            {
                this.ironGolemRightArm.rotateAngleX = -0.8F + 0.025F * this.func_78172_a((float)j, 70.0F);
                this.ironGolemLeftArm.rotateAngleX = 0.0F;
            }
            else
            {
                this.ironGolemRightArm.rotateAngleX = (-0.2F + 1.5F * this.func_78172_a(p_78086_2_, 13.0F)) * p_78086_3_;
                this.ironGolemLeftArm.rotateAngleX = (-0.2F - 1.5F * this.func_78172_a(p_78086_2_, 13.0F)) * p_78086_3_;
            }
        }
    }

I was already using that for the animation, im not sure what you mean by corrupted though, also why would the file being corrupted stop the animation from working.

P.S in order to make an animation work you have to make an attack timer in your mod class, which is what I assume is/was the problem.

Im serious don't look at it!!

File corruption with techne example :

LegR = new ModelRenderer(this, 46, 0);
      LegR.addBox(0F, 0F, 0F, 4, 16, 4); // The variables names should begin with a lower case letter
      LegR.setRotationPoint(1F, 8F, -2F);
      LegR.setTextureSize(64, 64);
      LegR.mirror = true; // Miror texture should be after the initialization
      setRotation(LegR, 0F, 0F, 0F);

 

The reason that your animation doesn't work is because your event is fired once, but the method setLivingAnimation is fired every render tick.

Why are you using a Forge Event to handle your animation?!?!?!?! No no no. Not good.

 

It's YOUR entity class, and YOUR model, use the methods already available to you: ModelBase#setLivingAnimations has access to any of your entity fields that have been synced to the client, whether by packet, DataWatcher, or World#setEntityState + YourEntity#handleHealthUpdate.

which forge event? @SideOnly(Side.CLIENT) this?

Well, it's not really a Forge event, but it looks as though you copied it from a Forge event and may have been expecting it to act like one:

// in your Model class:
public void LivingAttackEvent(EntityLivingBase entity, float par1, float par2, float par3){

Where are you calling that from? Are you calling it at all?

 

Perhaps you should check out Jabelar's tutorial on animations / entities.

It looks like you are trying to mimic the vanilla Iron Golem attack animation, correct? In any case, you should look at the Iron Golem code, both the Entity and the Model, to see how it handles the attack timer / animation.

 

Here's what you should pay attention to / learn as you look through the IronGolem classes:

1. Golem attacks, calls world.setEntityState(this, byteFlag)

2. Minecraft sends a packet for you that calls golem#handleHealthUpdate(byteFlag) on the client side

3. When byteFlag is received, it starts the golem's attack timer - again, this is on the client side, which is important

4. attack timer is decremented every tick in the entity's onLivingUpdate method

5. In the model class, which is client side, it can now see that the attack timer is ticking and animate accordingly in setLivingAnimations
