Hello. What would be the best way to determine when the user’s touch.position comes into contact with a collider? I know that is is using a raycast, but how do I draw a ray from the touch.position? Thanks
Use the ScreenPointToRay
It should be easy to rewrite the following script to use Touch input instead of mouse input.
