To create a rotating radar, you'll need a Radar (obviously), a LoopTimer, and two Add components. You'll need to set the LoopTimers TickTime property to 0.3 (you can vary this value.)

The first wire will run from the LoopTimer to the first Add component. This is to set the number of degrees that we want to rotate the radar (in this case, 30.)

The second wire runs from the first Add component to the second Add component.

The third wire runs from the second Add component back to the first one. This is the "loop" or "flip-flop" that increments the radar's angle.

The fourth wire goes from the first Add component to the radar. This is what "rotates" the radar".

Now that we can rotate the radar, we need to stop it when it finds a target. The fifth wire runs from the Radar to the LoopTimer, telling it to stop.

Lastly, if we lose the target, we need to start rotating the radar again. The sixth wire takes care of this.

Now you can make a rotating radar whenever you need one!
