Radar script modification, translate x y when camera spins.

Question

I'm using the radar script found at http://www.unifycommunity.com/wiki/index.php?title=Radar Works great for creating a HUD radar.

It works by showing objects around a central object, in my case the camera. What I need to do is translate the x y so when my camera spins around the objects that were behind me on the radar are now in front. My first guess was to use transform.TransformDirection somehow but it's a little unclear to me at the moment.

void drawBlip(GameObject go, Texture2D blipTexture) { if (_centerObject) { Vector3 centerPos = _centerObject.transform.position; Vector3 extPos = go.transform.position;

     float dist = Vector3.Distance(centerPos, extPos);

     float bX = centerPos.x - extPos.x;
     float bY = centerPos.z - extPos.z;

     bX = bX * radarZoom;
     bY = bY * radarZoom;

     if(dist &lt;= (_radarWidth - 2) * 0.5 / radarZoom)
     {
         Rect clipRect = new Rect(_radarCenter.x - bX - 1.5f, _radarCenter.y + bY - 1.5f, 3, 3);
         GUI.DrawTexture(clipRect, blipTexture);
     }
 }

By the looks of it just change:

Vector3 extPos = go.transform.position;

to:

Vector3 extPos = _centerObject.transform.InverseTransformPoint(go.transform.position);

That was 98% right, but I used InverseTransformDirection() and it worked perfectly. Thanks!
