Spawning AI That Will Follow A Main Character

Hi, I am trying to figure out how to make a blue print that will spawn enemies that chase the main player. I am hoping to replicate something like Left for Dead 2 where zombies just keep spawning and chasing the character.

So far I have been able to place an AI on my map and then have him follow my character.

Here is a picture of my level blue print:

I found one way to do it although I would make sure you have a spawn cap before you use it.
