A simple Enemy detection set piece. Here is what it does.

1. rotates between two points (the distance and speed can be adjusted)
2. if player is found then follows the player instead of rotating, this can be changed to do damage or shoot at etc or just a plain game over screen.
3. blinks and disables the vision cone blink is set to happen randomly

1. loses sight of player if behind a wall and returns to rotating.

Really simple blueprint for your game.
