Zombies getting stuck when chasing you?

[Chilton]

Add in more nodes, and for christ sake make sure theyre connected. To see how the nodes are ordinated, go into MapView, and turn on nodes, the line connecting nodes show how theyre connected. They should avoid any obstacles in a 2x2 grid area.

Thanks for this, I didn't realise you needed to add nodes for AI to work. They still seemed to be getting stuck on stairs, so I added like 3 for each step - is this right? Can you have too many nodes?

You can, yes. Stairs can be tricky, but the key is to have one for each step, and if scripting have no movement delays.
