i used if($player->isFlying) for testing only xd

 

Avoid calling close() on entities inside an event.

 

I used $player->kick it still shows that error

 

Maybe if instead of using player->kick or close after your checks, you set a variable to true, and at the very end of your method that handles the event, if that variable is true, kick the player. That way the plugin isn't trying to use information from a closed player.

 

You from a array?

Like that?

PHP:

$hacker = [];

if(in_array($player->getName(), $this->hacker){
}

 

Nvm on that, try return; after you kick the player.

 

Already tried didn’t work

 

After both $player->kick()?

 

Yup didn’t work I tried

 

Try scheduling a delayed task (1 tick delay) which kicks the player.
