1.15 Mcreator (2020) Mob Sitting

hey guys im stuck on another code part here, important one; making the tamed mob to sit (the model sit), i cant figger it out the part marked on the code below:

private void setRotation(ModelRenderer model, float x, float y, float z) {
			model.rotateAngleX = x;
			model.rotateAngleY = y;
			model.rotateAngleZ = z;
		}

		
			// SITTING CODE

		

		public void setLivingAnimations(T entityIn, float limbSwing, float limbSwingAmount, float partialTick) {
        
        	if (entityIn.isSitting()) {       <---------------- THIS PART
