"""An ender pearl in flight when its thrower dies, on a dedicated server, against vanilla's, seen by a vanilla client.
|
|
|
|
A vanilla dedicated server and Horizon's (`horizon-client --dedicated --nogui`) each serve a copy of one flat world
|
|
vanilla generated first, with Alice an operator in survival. LocatorBarClient (a player made of vanilla's protocol
|
|
code) throws an ender pearl straight up (ServerboundUseItemPacket), runs /kill on itself while the pearl flies,
|
|
presses the death screen's button (PERFORM_RESPAWN) and waits for the pearl to come down, with the rule
|
|
ender_pearls_vanish_on_death true: ThrownEnderpearl.tick discards a dead owner's pearl, so the respawned player is
|
|
never teleported. The teleports, game mode changes and respawns Alice is sent from the throw on are compared
|
|
exactly.
