We need to pick up the flag with check == 64, so we look at the script that
generates flags to figure out which one has idx == check == 64.
If an enemy is within 3 units, it will always move in a direction. If there is no better move, it will move to the right.
Item IDs are generated per floor with respect to how many items are currently on
the floor. Item pickup picks up all items with the same ID on the current floor.
Resort items will renumber the item IDs you currently have with respect to the
order in the script. We pick up items one by one and renumber them so that id = 0. This allows us to pick up more than eight items at a time. Once we have more
than thirteen items in our inventory, we can resort again to make something with
id == 12, allowing us to pick up our flag remotely.
socket.io event handlers run asynchronously. If we launch multiple
socket.on("action") handlers and travel onto the stairs, it will increment our
floor number multiple times and hopefully set our game state to floor 5. We can
spam movements via some simple javascript.
for (i = 0; i < 10; i++) {
socket.emit("action", {type: "move", direction: 4});
}
