I have a problem where the main actor is going throughout the world and as he scrolls up enemies randomly spawn in a given area. What I am trying to do is to in some sort delay the spawning of the enemy if the character is in close range to where the enemy might spawn. Any help is greatly appreciated. Thanks in advance.
Here is the enemy code
