Enemies to roam in an area

I'm new to Construct 2 and have looked around but can't find an exact answer I am looking for.

I want the enemies to roam around on the layout randomly on a top down viewed game. Is there anyway to do that?

Similar to how you would do it in the platformer begginers example, but instead of having invisible blocks that just turn them left and right you add other options, up, down, etc...

Thanks. I got them to stay inside but how do I make them roam randomly?

The enemies seem to follow a certain pattern right now.

You can update your logic to say when they collide with it pick a random number between 1-4 and send them in a direction based on the number. Or if they have other things they can do besides just move in directions you can have them do other things as well, jump, attack, fall asleep, etc...
