# Phaser: How to use a simple timer from 0 to 3

I am using the following code (which is a simplified snippet in order to make it more readable):

var player;
var box_tnt;

function create (){
}

//the function hitTnt stop the game because the player died
function hitTnt (player, boxes){
this.physics.pause();
player.setTint(0xff0000);
player.anims.play('default');
gameOver = true;
textGameOver.setText('GAME OVER');
}

• Actual comportment:

When the player hits the bomb: player die; end of the game

• Desired comportment:

When the player hit the bomb: the bomb wait 3 seconds and then explode! If the player is too close, he dies. But I struggle a lot to use a timer even after reading a lot of examples in the forum; I am a newbie concerning Phaser so I didn't succeed to it so far.
