Unreal has an actor called a PathNode , which does exactly what we want—we can
place it in the hallway, and Unreal will connect our rooms together. Right-click on
the floor, then select Add Actor | Add PathNode , or beter yet use the shortcut—
hold down the key and click on the floor:
An apple icon appears. Click the Build Paths buton and you should see some more
connecions. You may have to move the PathMode around and rebuild paths to get
it to connect up, or you may need to add more than one PathNode .
Add a few PathNodes to your map now and make sure every room is connected by
paths. Run the game and add a few bots, and you'll see they're now able to traverse
the whole space.
