I'll explain my issue (My English is a little lame sorry).

I have a Player ( Camera) who is able to move in a Unity Scene. In this scene there is some GameObjects. Those GameObjects May be too far for the camera to see. What I want to achieve is to have an UI Image that appear in the direction of every objects. Even if the objects are too far.

Example : The player stand at a position. In front of him there is an object that is far. I want to have a GUI on screen who says "there is an object at 200 m ". If there is an object behind him I dont want anything to appear. But if he turns back, it will appear cause the player is in the direction of the said GameObject.

I really hope I made myself clear. Please tell me if you need any further explanations. Thank You community !
