Question by MonkeyAssassin8 · Aug 25, 2010 at 01:51 AM · topdownshooterpointerlaser

How do I make a laser pointer?

I am making a top down shooter and I would like to know how to make a laser pointer. I currently have a directional light, but that only shows where it hits, I want it to light up it's whole path in a small beam.

I actually want what you originally had. A light that shows where it hits without going through the object. You said directional light. Did you mean spot light? Could you say how you achieved it.

maybe the code would be like this?:

function Update () { var lineRenderer : LineRenderer = GetComponent(LineRenderer); lineRenderer.useWorldSpace = false; lineRenderer.SetVertexCount(2); var hit : RaycastHit; Physics.Raycast(transform.position,transform.forward,hit); if(hit.collider){ lineRenderer.SetPosition(1,Vector3(0,0,hit.distance)); } else{ lineRenderer.SetPosition(1,Vector3(0,0,5000)); } }

@script RequireComponent(LineRenderer)

and use a texture like this
