Description
Expected behavior
If I override player movement in a PlayerMoveEvent, it should not call a PlayerTeleportEvent. I believe this is a genuine oversight, while it is niche I do believe it needs to be addressed for consistency
@EventHandler
public void onPlayerMove(PlayerMoveEvent event) {
// Why does this call PlayerTeleportEvent ?
Location to = event.getFrom();
to.setPitch(event.getTo().getPitch());
to.setYaw(event.getTo().getYaw());
event.setTo(to);
}
Observed/Actual behavior
When using the above logic to override the player movement, it calls PlayerTeleportEvent,
Steps/models to reproduce
public class Main extends JavaPlugin implements Listener {
private static boolean shouldFreeze = false;
@Override
public void onEnable() {
getServer().getPluginManager().registerEvents(this, this);
getServer().getScheduler().runTaskTimerAsynchronously(this, () -> {
shouldFreeze = !shouldFreeze;
}, 20, 100);
}
@EventHandler(priority = EventPriority.MONITOR)
public void onPlayerTeleport(PlayerTeleportEvent event) {
getServer().broadcastMessage(event.getCause().toString());
}
@EventHandler
public void onPlayerMove(PlayerMoveEvent event) {
if(shouldFreeze) {
// Why does this call a teleport event?
Location to = event.getFrom();
to.setPitch(event.getTo().getPitch());
to.setYaw(event.getTo().getYaw());
event.setTo(to);
}
}
}

Research direction
Start by reproducing the supplied listener with PlayerMoveEvent and PlayerTeleportEvent on the reported Paper 1.19 version. Trace how changing PlayerMoveEvent#setTo produces the teleport event, then verify that movement overrides no longer emit PlayerTeleportEvent while genuine teleports still do.
