Selecting All Players

How can I teleport all players to a location, or even just select all players, rather than just a $sender?

Do a foreach loop on $server->getOnlinePlayers()

foreach($p->getLevel()->getNearbyEntities(new AxisAlignedBB($pos->getX()-10, $pos->getY()-10, $pos->getZ()-10, $pos->getX()+10, $pos->getY()+10, $pos->getZ()+10), $p) as $entity)

(+/-10 is the range)

That's slower.

Ok dont know but u have a range so not all player will be telepotet only the player nearby u

i suggest you dig out the plugin "LocalChat" in the plugin repo

Yes... but, you can also select by player using chunks.

Simple the same i have made a minigame with that. If a player is near 10blocks and a other player break a grassblock all players near will be teleport random in the sky for fall damage... other damage is disable in world ^^

But how would you teleport ALL players in a given world to a location? Not all players near you, all players in the world.
