Title: Best way to anchor a widget to an object in the scene?
Post by: laurentl on June 10, 2013, 01:53:28 PM

I see that anchor only attach to camera, panels and widgets. Is there a script to attach to a 3D object so that the health bar follows the object?

No, that's what UIFollowTarget does from the HUDText add-on. Also it's just 3 lines of code anyway.

I'm actually using it for context menu :)

I tried this but the UI gets sent really far.

1.         void LateUpdate()
2.         {
3.                 transform.position = cam.WorldToScreenPoint (target.position);
4.         }

That's because WorldToScreenPoint gives you screen space coordinates, and then you just go and assign them to transform.position which is in world space coordinates.
