Is it possible to check which point is being touched?
Hello, guys. I'm coding with some primitive meshes such as sphere, cube, cylinder.
For now, I'm planing about game like billiard.
If I add force to specific mesh, the mesh checks which point is being touched and how many powers received. And the mesh goes to vector which is opposite vector of touch vector.
As I know, in Unity, objects check only whether it is touched or not by OnTriggerEnter or OnCollisionEnter and so on, but there isn't any functions which I planned.
Is anybody knows how to check which point is being touched in meshes? [If possible, I'd like to know absolute position in gameScene.]
THx for reading!

You can solve this using Physics.Raycast(). There are a bizillion posts on Raycasting on UA.
@robertbu Thx for replying. But I think that raycast is only for forward direction, nor for left, right, nor back. However I'll check the raycast references. Thanks!
Raycast can go any direction you want. You can raycast any down the length of a cue for example to see where the cue is hitting (or will hit if it is not yet in contact). Alternately, you can get position information from OnCollisionEnter(). The Collision that is passed as a parameter in this callback contains an array of contact points in world space.
