Stick an object to the ground while moving?

Question

Hi everyone,

I'm trying to make a basic movement engine for a rpg game without using the character controller or a rigidbody. The reason I don't want to use them is because there is no element of gravity in my game (you can't jump or fall). I am trying to find the best way to get my player (a cube that can move in 8 directions) to stay attached to the ground, (which has sloped areas as well as flat) while moving (without using gravity). What would be the best way to go about this?

I have looked around the web for possible solutions and found that "raycasting" may have been used for this, but I have no idea how I would set that up.

Thanks in advance! (Sorry for all the parenthesis :I )

 function Update () {
     var hit : RaycastHit;
     if (Physics.Raycast (transform.position, -Vector3.up, hit)) {
         var distanceToGround = hit.distance;
         //use below code if your pivot point is in the middle
         transform.position.y = hit.distance - transform.collider.bounds.extents;
         //use below code if your pivot point is at the bottom
         //transform.position.y = hit.distance;
     }
 }

Put this code in your objects movement script. It should work...
