Need help with enemies

Dwight · January 3, 2007, 11:43am

Hi peeps,

I’m building a sort of maze game, I’m pretty new to this. I’ve made games before but none of them where tile-based.

Now I followed a tutorial from Outside Of Society, this tutorial helped me with the tiles, walls and enemies.

The enemies are pretty basic and choose random directions. The problem is that I don’t want the enemies to be able to walk over each other, but they have to find a new direction at that moment.

But I can’t figure out how :h:

here is the code of the enemy MC:

Is there someone who can give me a hint, how to solve this? Or even better, maybe knows how to solve this?

Thanks in advance
