    Say I have an enemy, he is on screen. His attached world space UI element is directly above his head.
    Now say I have an off-screen enemy. What I want is for his attached world space UI element to be at the edge of the screen closest to him.

    Essentially if they are visible on screen, have the UI element follow them. If they are off screen, have the UI element follow them at the closest point that is still on the screen.

    I can do everything except I can't determine how to do that last bit. Any thoughts on this?

    Thanks!

    This is the same concept as the quest marker and whatnot. CodeMonkey has an excellent tutorial on it, but the meat of it is simple math, you can check around at the 5 minute mark or so:
