Solved Wait for event

Hi, is there anyone know how to make a code tht wait until an event is executed?
My code↓

PHP:

public function onCommand(CommandSender $sender, Command $cmd, $lbl, $args):bool{
    switch($cmd->getName()){
        case "test":{
            $sender->sendMessage("Please execute a block");
            //wait until the event below is executed
            break;
        }
    return true;
}

public function onInteract(PlayerInteractEvent $event){
    $player = $event->getPlayer();
    $block = $event->getBlock();   //question: how to save this variables to the function above??
}

 

Something like this would work

PHP:

private $wait = [];
public function onCommand(CommandSender $sender, Command $cmd, $lbl, $args):bool{
    switch($cmd->getName()){
        case "test":{
            $sender->sendMessage("Please execute a block");
            $this->wait[$sender->getId()] = true;
            //wait until the event below is executed
            break;
        }
    return true;
}

public function onInteract(PlayerInteractEvent $event){
    $player = $event->getPlayer();
    $block = $event->getBlock();
    if(isset($this->wait[$player->getId()]){
        //do stuff
        unset($this->wait[$player->getId()]);
    }
}


 

Ohh tq
