Question by william9518 · Aug 30, 2013 at 11:52 PM · raycastraycastingline drawingbullet marks

Raycast Bullet Tracer.

How would one make a Raycast bullet tracer? I have tried, but the tracer only appears if I hit something, as I used

 if(Physics.Raycast(transform.position, transform.forward, Hit, maxDistance)){

With the Hit variable being a RaycastHit. But I want a tracer even if I don't hit something. I have tried using a temporary Vector3 storing the LineRenderer's second position parameter (The end of the line), like this:

 var temp : Vector3 = gameObject.transform.position += new Vector3();

But this does not correspond with the rotation of the player. How can I do this?

Thanks in advance, William

You can simulate the hit by deciding on a distance. So the logic would look like:

 var hitPos : Vector3;
 if(Physics.Raycast(transform.position, transform.forward, hit, maxDistance)){
     hitPos = hit.point.
 }
 else {
   hitPos = transform.position + transform.forward * someDistance;
 }

Where 'someDistance' is the distance you decided on to simulate a hit.
