Howdy Everyone! I have an orthographic camera facing z negative at positive z = 20. I want the player to pan the camera with one finger and zoom the camera when they pinch. So far I have the pinch function working but I can't figure out why my pan function broken. Can anyone tell me what I'm doing wrong?
