Floating Healthbar almost there, problems on camera zoom...

Unity Engine
1

I have a very simple healthbar OnGUI setup for my enemies:

    void OnGUI()
    {
        // Get our position where the enemy is, tried setting this to values above/below Y axis, didn't work
        Vector3 worldPosition = transform.position + new Vector3(0.0f, 0.0f, 0.0f);
        Vector3 healthBarPos = Camera.main.WorldToScreenPoint(worldPosition);

         // Draw a simple texture for a black background over the enemy
        GUI.DrawTexture(new Rect(healthBarPos.x - 26, (Screen.height - healthBarPos.y) - 110, 62, 8), healthBackTexture);
         // Draw a simple texture for a green health bar inside the black background, it scales off the health / maxHealth
        GUI.DrawTexture(new Rect(healthBarPos.x - 25, (Screen.height - healthBarPos.y) - 109, 60 * (health / maxHealth), 6), healthTexture);
    }

The healthbar displays over the enemy just fine, the problem I run in to is if I zoom in the healthbar will float down towards the feet of the model, this also happens for the GUI.Label I was using for the enemy name but I edited that out to make things super simple.

Here’s a quick youtube video show how it looks when i zoom in / out.

Is there a way to set the script to some how retain the position of always being over the enemies head and not float down when the camera zoom changes? I’m sure its some super simple thing for the position/viewport but I can’t seem to find anything or figure it out. I’m sure i’ll feel like an idiot once I figure it out. lol

Vector3 worldPosition = transform.position+newVector3(0.0f, 0.0f, 0.0f);

Change the +new Vector3 part to reflect the height of your character.
An example would be…

Vector3 worldPosition = transform.position+newVector3(0.0f, 2.0f, 0.0f);

Thanks, that put me in the right direction. Turns out I had to remove the -110 from the Y position as well, since 110 is what puts it at the top when zoomed out but not when zoomed in. Managed to get it all working, thanks!
