2D GUI Group moving with players.

I have four players that have health and energy. The bars should all float just above the player’s heads, and move/update along with them.

I cannot figure out how to make the gui I have move, specifically because I’m using a “group”, and I’m not sure I fully understand it, or what to use instead.

Here is the current code I use, which only places it in the corner:

var barDisplay : float = 0;
var pos : Vector2 = new Vector2(20,40);
var size : Vector2 = new Vector2(60,20);
var healthBarEmpty : Texture2D;
var healthBarFull : Texture2D;
function OnGUI()
    // draw the background:
    GUI.BeginGroup (new Rect (pos.x, pos.y, size.x, size.y));
        GUI.Box (Rect (0,0, size.x, size.y),healthBarEmpty);
        // draw the filled-in part:
        GUI.BeginGroup (new Rect (0, 0, size.x * barDisplay, size.y));
            GUI.Box (Rect (0,0, size.x, size.y),healthBarFull);
        GUI.EndGroup ();
    GUI.EndGroup ();
function Update()
    // for this example, the bar display is linked to the current time,
    // however you would set this value based on your desired display
    // eg, the loading progress, the player's health, or whatever.
    barDisplay = health;

Health is a separate variable that starts at 100 and decreases as they take damage.

I considered just using several drawn boxes, and changing the size of that. Would that be a suitable way to do this? Is there an easy way to move this group?

Use Camera.WorldToScreenPoint to get the screen coordinates of your characters, and use these values to draw whatever you want to draw in your OnGUI function.
