I been trying to figure out how to change the default item swing of Minecraft (Where you just hack and slash) to where the item will follow the path of the mouse cursor (similar to how the Wii Sport's sword worked). Right now I've been trying to find the related class(s) to see how the vanilla animation works. So far, it seems that the EntityOtherPlayerMP and WorldClient class might be it.
Am I looking in the wrong classes, and any advice on how I could create the new animation?
