Question by rednax20 · Oct 04, 2014 at 08:24 PM · raycastpointfrom

raycast from a point straight down

I would like to instantiate a character from a random point, on a terrain. the only problem is that i won't know how high my terrain will be at that spot. my thought was i could ray cast from a point above the terrain so that I could take the raycasthit.point, and create the player.

the problem is i can't figure out how to ray cast without a camera (It may not even be possible)

so If someone could tell me how or link me to some documentation that would be great.

And if there's some other/better way to do this, I would definently try it.

thanks

First, you can use Terrain.GetHeight() instead of ray casting. If you really wanted to do a Raycast, it could be something like this:

 var hit : RaycastHit;
 var ray = new Ray(somePosition, Vector3.down);
 if (Terrain.activeTerrain.collider.Raycast(ray, hit, 1000)) {
     Debug.Log("Hit at "+hit.point);
 }
