Hello,
I’m developping a basic application to load and modify molecules and my main goal is to implement Kinect to do it.
So far I’ve been able to do it with a mouse and I would like to do it with my right hand.
After searching for a while I tried to define my cursor in a screen environment like if it would be done with a mouse (Input.mousePosition.x) substituting this for the hands coordinates (normalized for the screen dimensions).
I can’t make the cursor follow my hand, but I can make a game object follow any part of my body so my coordinates are being imported and when I debug my control variables they return a value contained in the screen dimensions.
I guess my error is in OnGUI().
Can anybody help me.
Thanks in advance.
