I have written a script here that is supposed to gather a list of objects to be circled, and apply a guitexture circle around each one. I am having 2 problems.
It is not placing the textures in the right places. I only get 2 placed, one stretched horizontally in the center, and one stretched horizontally centered in the bottom left corner (3/4 of it is cut off). I know there should be more than that and that those 2 spots are not the right locations. All the objects are properly tagged and parts of this code have worked before when it was applied to a single object that was selected. In fact, the only things that have changed since the last working version in DrawHUDMap() is the instantiate and the arrays. replace the arrays with single gameobject variables and comment out the instantiate line and youll more or less have the working code I had before.
The other problem is an error:
IndexOutOfRangeException: Array index is out of range.
(wrapper stelemref) object:stelemref (object,intptr,object)
HUDMap.DrawHUDMap (UnityEngine.GameObject[ ] targets, Color ringcolor) (at Assets/Scripts/HUDMap.js:76)
HUDMap.Update () (at Assets/Scripts/HUDMap.js:25)
It seems to me if the out of range error there is fixed, it will probably draw the circles correctly.
Here is the script. Sorry about all the commented code, I’ve been trying to work through this, unsuccessfully, since I added arrays. I didn’t clean it up so the error would show the correct line in this code.

if(tar[0] != null){
DrawHUDMap(tar,Color(1,1,1,1));
}else if(tar[0] == null){

}
}
function DrawHUDMap (targets:GameObject[],ringcolor:Color){
for(var i=0;i<targets.length;i++){
var target : GameObject = targets[i];
var bounds : Bounds = target.collider.bounds;
var cam : Camera = Camera.main;
var center : Vector3 = cam.WorldToScreenPoint(bounds.center);
var radius : float = 0;
var r : float = 0;
// top

if(r > radius) radius = r;
//center is the objects position, z is the camera distance value
//diameter will be the width of the texture containing the selection ring.
//radius = radius*1.25;
tring[ontarget] = Instantiate(RingPrefab, target.transform.position, target.transform.rotation);
//Instantiate a ring. here, then apply this code to it
if(radius < 10) radius = 10;
if(center.x>0 center.x<Screen.width center.y>0 center.y<Screen.height center.z>0){
tring[ontarget].guiTexture.color = ringcolor;
tring[ontarget].guiTexture.color.a = 400/(radius*radius)+0.1;//(radius*10/250*10)+5;
//Debug.Log(tring.guiTexture.color.a);
tring[ontarget].guiTexture.enabled = true;
tring[ontarget].guiTexture.pixelInset = Rect(center.x-Screen.width/2-radius,center.y-Screen.height/2-radius,radius*2,radius*2);
}else if(center.x<=0 || center.x>=Screen.width || center.y<=0 || center.y>=Screen.height || center.z<0){
tring[ontarget].guiTexture.enabled=false;
}
ontarget++;
if(ontarget>totaltargets) totaltargets = ontarget;
//Debug.Log(center.z);
//if (center.z<0)
//tring.guiTexture.enabled=false;
//Debug.Log(guilocation);
}
}
So, I guess my basic questions here are probably: How do I increase the size of an array? Or better yet, How do I define it as a dynamic array? Is that the problem I’m having with the rings not being there, or in the right spots?
Thanks
EDIT: You can ignore line 36 about the null reference error, that’s been fixed.
