I am hoping to use this infor so I know where the mouse actually WAS, so that I can use this to figure out where the center is? If that makes sense? I am really feeling my way through this. I am created a VR gun for the Oculus Rift, it just getting anything other than Relative mouse movements...I did get absolute mouse mode working , the motion is right just a LOT of jumpy right angle in between movement...but this is what I am doing.
