    Hi, I thought I'd use ClosureTask but when I try to stop RepeatingTask I still can't get the TaskHandler inside Closure. What should I do with this?

    PHP:
    $task = new ClosureTask(...);
    $this->getScheduler()->scheduleRepeatingTask($task20);
    $handler $task->getHandler();
    // Do whatever you want to do with the handler, f.e: Cancelling the event
    where $this is an instance of PluginBase

    PHP:
            $task = new ClosureTask(function (int $currentTick): void {
                if (
    mt_rand(0100) === 0) {
                    
    //end the task...
                    //what TaskHandler...
                    
    $this->handler->cancel();
                    return;
                }
                
    $this->getServer()->getLogger()->info("Hello!");
            });
            
    $this->handler $this->getScheduler()->scheduleRepeatingTask($task20);
    Is there a smart way to cancel a task from within a closure like this?
    Otherwise, you have to store Task in the property of the main class.
    I don't know if this is smart.

    Don't think you can do that, no

    You can simply do this
    PHP:
    $handler $this->getScheduler()->scheduleRepeatingTask(new ClosureTask(function (int $currentTick)use(&$handler): void {
                if (
    mt_rand(0100) === 0) {
                    
    //end the task...
                    
    $handler->cancel();
                    return;
                }
                
    $this->getServer()->getLogger()->info("Hello!");
            }), 
    20);
