Convert World Space GameObject Position to Screen Space Canvas UI Position

Question

I have a GameObject that is in World Space. I also have UI GameObject that is in Canvas that is Screen Space that uses Camera.

How can I convert the position of World Space GameObject and assign it to the UI GameObject in Screen Space Canvas?

WorldToScreenPoint doesn't use help.

Answer 1

camera.WorldToScreenPoint(transform.position) should work. Keep in mind! 0,0 is bottom left. So to position a UI element, you need to invert Y

To do that, you can do this:

Vector3 screenPos = camera.WorldToScreenPoint(transform.position);
Vector3 uiPos = new Vector3(screenPos.x, Screen.height - screenPos.y, screenPos.z);

Hope it helps!
