How: Make enemy "wander" in area

Top down zombie shooter:

How do I make zombies wander around in a given area?

Pathfinding behavior seems too specific as it only goes to one location. This is good because I can make it destroy a door, but once the door is destroyed, I want the zombie to enter and wander around looking for the next thing to do (break windows, break more doors, break walls, find player)

Here is my cap file

you could do pathfinding, but when he gets to a new location, he starts calculating the next location. Zombies like to linger a little, so you could do something like. On arrive at location, wait 3 seconds and start to calculate next location. Just an idea

You could randomize the forward movement and angle of movement. Also move towards a point. Will give a wandering effect. If you ever get to the point you can just randomize a new target point within a given range.

EDIT: Had some time so put the example together. Every now and then exhibits a bit of mob mentality, but explains the idea.

This is great! Thanks. However, it's not following the player as much as I want to.

add something like Line of Sight, when they get close make them follow your guy.

There was a plugin called Running away or something, look it up, it does just that- random going around
