    I have taken the ShootBallFPS script, and I am trying to change it to make the instantiated "ball" begin at a different location than the person shooting it. This is because it is colliding with the player model (it's a 3rd person camera angle). So, I am trying to get the projectile to start out a little bit in front of the player. I am having no luck.

    Basically, I want the projectile to start out at +5 units along the local z axis of the "shooter" before going on its way.

    Thanks for any help anyone can offer.

    Code (csharp):
    1.  
    2. var shoot : Rigidbody = Instantiate (ball, transform.position, transform.rotation);
    3.  
    transform.position is the position where the ball will be spawned.
    You want to transform the local space direction to world space, you can use the TransformDirection function for this.
    So you want to instantiate it 5 units in front:

    Code (csharp):
    1.  
    2. offsetPosition = transform.position;
    3. offsetPosition += transform.TransformDirection (Vector3.fwd * 5);
    4. var shoot : Rigidbody = Instantiate (ball, offsetPosition, transform.rotation);
    5.
