Radar conundrum

UI
1

This my Radar Idea. I am building a FPS to play over a LAN. And I want the players to have a unique radar on the GUI.

The radar is to be a bunch of Red dots on the GUI that will tell the player where his Enemies are. Like if an enemy is above him the red dot will be at the top of his GUI, and As the player looks up the red dot will than land in the center of the enemy and follow him as long as he is in view. If the target flies off the screen to the left the radars dot will move to the left of the screen and not move except up and down depending on the characters movements.

IS this idea even possible. And if so what should I look in to to start scripting it out. All the assets for the Radar (the dots) are done already. So all is left to do is set up the scripts

Yes, it’s very much possible. Basically, you need to find out the screen space position of your enemy. This can be done using Camera.WorldToScreenPoint or Camera.WorldToViewportPoint:

On top of that, you may need to add some additional checks to find out where the enemies outside of your screen are. The Plane class is very handy for this. You can use GeometryUtility.CalculateFrustumPlanes to obtain the six planes that make up your viewing frustum.
