Object following player and object moving away from the player

In my game, BruhAdventure there will be cops walking around and if you do something wrong they will attack you if you are near and npcs that are walking around will move away or attack you aswell.

I would just make it a bouncing ball object -- look in direction of your object - to move way you could have an invisible object act as a sensor to send the target object in random directions if it overlaps your sensor. Of course the sensor would be invisible.

What about if it's in a platform game?
