It's built-in wall checking for an object when move is called.

You use it like this:

move(dx, dy, time, 4);

If you want blockcheck and eventwhendone (onMovementFinished) you do:

move(dx, dy, time, 4 + 8);

Personally I have had no pleasant experiences with it at least on the serverside and can't really recommend it then again I haven't used it in ages.
