I'm trying to make a laser for a weapon in a space ship game I'm making but not having much luck. I've tried using raycasts and a line renderer but then the line only shows when you hit something and I need it to show all the time. Does anyone have any ideas? I'm using unity free and JavaScript.
**EDIT**:
here is my script so far:
#pragma strict
var LRenderer : LineRenderer;
function Start () {
gameObject.AddComponent(LineRenderer);
LRenderer = GetComponent(LineRenderer);
LRenderer.SetPosition(0, transform.position);
LRenderer.SetPosition(1, transform.position);
LRenderer.SetColors(Color.blue, Color.white);
}
function Update () {
var ray = new Ray (transform.position, transform.forward);
var hit : RaycastHit;
if(Input.GetKey(KeyCode.Space)){
if(Physics.Raycast(ray, hit)){
LRenderer.SetPosition(0, ray.origin);
LRenderer.SetPosition(1, hit.point);
}
}
}
The issue is I can figure out how to make the ray be drawn while shooting as well as when it hits. It this case the linerenderer only shows when the ray hits, and I want it to show while the ray is firing along the ray.
