How to do action all 10 seconds

Hi,
I'm making a minigame and need things like a start counter.
Which is the most performant way to make such a counter in a PocketMine plugin?
For example, run Message A after 10 seconds, ...

if($this->time == 0) $this->time = 0?

PHP:

if($this->time > 0){
   $this->time--;
} else {
   # Send message and stop destroy this task
}


It's not! Your code will be repeated after 10 seconds will be passed, every single second. This what player would see:

PHP:

The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!
The game has started!


And how the code can be true?

DID YOU KNOW : That you're resetting $time to 0 when it is 0? and using $this->time-- to make it -1?

Sory I Forgot Some Thing
This IS True

PHP:

public $time = 0;
public $pla = 0;

public function onRun($tkck){//$this->time--;
if($this->pla == 1){
$this->time--;
if($this->time == 0){//-----------------------
// code
$this->pla = 0;
}}
}// How Can Start Time !
$this->time = 10;
$this->pla = 1;
//
true :)


do you know what you're doing? No

Yes I Know
You Can Test IT

Again, you created infinity loop. (Don't point out that it can be cancelled from other class)

Test IT

If I test it, nothing will happen.

I USE This For My Games

PHP:

public $time = 0;
public $pla = 0;

public function onRun($tkck){//$this->time--;
if($this->pla == 1){
$this->time--;
if($this->time == 0){//-----------------------
// code
$this->pla = 0;
}}
}// How Can Start Time !
$this->time = 10;
$this->pla = 1;
//

There I can easily add more conditional checks.

Run this script.

PHP:

<?php

$timer = new Timer();

for($i = 0; $i < 50; $i++){
   $timer->onTick($i * 20);
}

class Timer {

   public $time = 10; // # Ten seconds when something will happen!
  
   public function onTick($currentTick){
     $this->time--;
     if($this->time == 0){
       $this->log("10 Seconds passed!");
    
       $this->time = 0;
     } else {
       $this->log("".(($currentTick / 20)));
     }
   }
  
   public function log($msg){
     echo "".$msg."</br>";
   }
  
}

?>

That code was made to test yours

$this->time = 0;
} else {
Time == 0 ?
10 sec passed
And This IS Not yours
It's a clear 100%
I Think You Have Some Problem With Your Code
I Didnot see Your Code
All Your Code IS Err

It's a clear 100%
