Displaying a radar to indicate the relative locations of objects
A radar displays the locations of other objects relative to the player, usually based on a circular display, where the center represents the player, and each graphical blip indicates how far away and what relative direction objects are to the player. Sophisticated radar displays will display different categories of objects with different colored or shaped blip icons.
In the screenshot, we can see two red square blips, indicating the relative position of the two red cube GameObjects tagged Cube near the player, and a yellow circle blip indicating the relative position of the yellow sphere GameObject tagged Sphere. The green circle radar background image gives the impression of an aircraft control tower radar or something similar:
