QuoteHowever, we could add a serverside check if the player is very close to the world bounds (i.e the point at which the client starts slowing down the player - which is ~ 16 blocks from the world edge), then trigger an event and/or set a bool. It wouldn't be 100% perfect because the player could still move a bit closer to the edge at that stage. Would that still work for you?
this should work. its mainly needed for my server clustering system. i just need a way to know when a player is at the end of the map so i can send them to the next server in the cluster.
