Rotating the right arm when holding a specific item

[TheMattyBoy]

I'm trying to make both the players arms go forward when they hold a specific item, but I can only get the left arm forward using 'heldItem[Left/Right]' due to the heldItemRight's switch() statement:

switch (this.heldItemRight)
{
    case 0:
    case 2:
    default:
        break;
    case 1:
        this.bipedRightArm.rotateAngleX = this.bipedRightArm.rotateAngleX * 0.5F - ((float)Math.PI / 10F) * (float)this.heldItemRight;
        break;
    case 3:
        this.bipedRightArm.rotateAngleX = this.bipedRightArm.rotateAngleX * 0.5F - ((float)Math.PI / 10F) * (float)this.heldItemRight;
        this.bipedRightArm.rotateAngleY = -0.5235988F;
}

rather than heldItemLeft's if() statement:

if (this.heldItemLeft != 0)
{
    this.bipedLeftArm.rotateAngleX = this.bipedLeftArm.rotateAngleX * 0.5F - ((float)Math.PI / 10F) * (float)this.heldItemLeft;
}

Well, this is what happens in

RenderLivingEvent.Pre

, in

RenderLivingEvent.Post

both arms render like on a regular item. Any suggestions? Here's my code:

@SubscribeEvent
public void onLivingRender(RenderLivingEvent.Pre event) {
if(event.entity instanceof EntityPlayer) {
	EntityPlayer player = (EntityPlayer)event.entity;
	if(player.getHeldItem() != null) {
		ItemStack stack = player.getHeldItem();
		if(stack.getItem() == GadgetItems.hang_glider) {
			ModelPlayer model = (ModelPlayer)event.renderer.getMainModel();
			model.heldItemLeft = 5;
			model.heldItemRight = 1; //this is 1 because of the switch() statement. If it's 5 it will render as 0.
		}
	}
}
}
