Problem about targetting multiple enemies

Questions & Answers

Currently I am using the ObjectLabel script to put a targetting reticle over targets in my space simulation game. But it works for just 1 target. I want the targetting reticle appear over all targets around the player.

So I created sphere with a collision trigger and added this script:

`
private var targetList : Array = Array();

private var targetPosition : Vector3;

var targetReticle : GameObject;

function Start ()
{

}

function Update ()
{

}

function OnTriggerEnter (other : Collider)
{
targetPosition = other.gameObject.transform.position;

targetReticle.SendMessage("AddItem",targetPosition);

    //Sends the target's position to the TargetReticle GUITexture object

}
`

Then I modified the ObjectLabel script as follows:
`

var target : Transform; // Object that this label should follow

var offset = Vector3.up; // Units in world space to offset; 1 unit above object by default

var clampToScreen = false; // If true, label will be visible even if object is off screen

var clampBorderSize = .05; // How much viewport space to leave at the borders when a label is being clamped

var useMainCamera = true; // Use the camera tagged MainCamera

var cameraToUse : Camera; // Only use this if useMainCamera is false

private var cam : Camera;

private var thisTransform : Transform;

private var camTransform : Transform;

//CUSTOM VARIABLES

private var targetList : Array = Array(); //List of Targets are stored here

var arrayLenght : int; //Lenght of the target array

private var i : int = 0;

function Start () {

thisTransform = transform;

if (useMainCamera)

    cam = Camera.main;

else

    cam = cameraToUse;

camTransform = cam.transform;

}

function Update ()
{
var arrayLenght = targetList.length;

for(i = 0; i <= arrayLenght; i++)

{
	Debug.Log("Value of i:"+i);

	Debug.Log("Position of the target:"+targetList*);*

  •   Debug.Log("Array lenght:"+arrayLenght);*

  •   if (clampToScreen) {*

_ var relativePosition = camTransform.InverseTransformPoint(targetList*);*_

* relativePosition.z = Mathf.Max(relativePosition.z, 1.0);*

* thisTransform.position = cam.WorldToViewportPoint(camTransform.TransformPoint(relativePosition + offset));*

* thisTransform.position = Vector3(Mathf.Clamp(thisTransform.position.x, clampBorderSize, 1.0-clampBorderSize),*
* Mathf.Clamp(thisTransform.position.y, clampBorderSize, 1.0-clampBorderSize),*
* thisTransform.position.z);*
* }*

* else {*

* thisTransform.position = cam.WorldToViewportPoint(target.position + offset);*

* }*
}
}
//CUSTOM FUNCTIONS HERE
function AddItem(item : Vector3)
{
targetList.Add(item);
}
@script RequireComponent(GUIText)
`
The code actually does get all the targets in the dedection sphere BUT it only puts the reticle on the last object in the array. How do I change the code to keep the reticle on till the objects get destroyed?
Thanks.

Isn’t it becouse you are actually only moving one sphere around and in the end it is on the last one?
“So I created sphere with a collision trigger and added this script:”
If you want more spheres you have to instantied them in the loop. Make this script more of a controller.
