Instantiating GameObject On The Surface Of Another GameObject On Tap

[mgear]

use raycast, to get tap location (and surface normal direction) on the 3d models mesh collider

Unity - Scripting API: Physics.Raycast

then can instantiate object on that hit point, and align to surface

Character align to surface normal ???

D'oh. I forgot the raycasting part. Here, try this instead: var hit : RaycastHit; var castPos = Vector3(transform.position.x,transform.position.y-.25,transform.position.z); if (Physics.Raycast (castPos, -transform.up, hit)) { transform.rotation = Quaternion.FromToRotation (Vector3.up, hit.normal); }
