[1.9]Swing left arm

[Ironfists]

Hi, I've got a pretty complex problem(I guess). I need that the player swing his left arm when right clicking, well that's easy by using the "swingHand(EnumHand)"

 

But, the more problematic thing is that I want to be able to swing both arms at the same time, and it is no possible with the vanilla code because there is only 1 variable for the swing animation so only the last hand will have the animation.

 

My guess is that I have to make a separate variable for the left hand animation and modify the "renderItemInFirstPerson" method in the ItemRenderer.class.

 

So how could I do so that the game use my own "renderItemInFirstPerson" method instead of the vanilla one?

 

edit: I don't care about the swing animation in 3rd person, I just want the 1st person player to see the animation

It doesn't seem to have a grasp on ItemRenderer

Because it contains the code that render the first-person right and left arm with along with their animation logic
