I don't think a query of "can be here" will cut it. You need something more advanced, and luckily, there is something that might work: Get a function CanMove, that gets the start and end pos, which must be exactly 1 block apart, and the entity dimensions, and return the bool result and the Y coord of the dest point.. That way you can make your A* algorithm without many changes and it will work even for doors and such. It still won't work for things like traversing a hole over a row of opened trapdoor's ledges, but hey, we'll even be better than vanilla because our zombies will walk around doors instead of trying to knock them down
