Hi all,

I modify the invader exemple [here](https://www.team-azerty.com/html/1erAvril/covid-19/), and I wanted to make it mobile friendly.

I add “button” :  
boutonGauche = game.add.button(0, game.world.height - 60, ‘bouton-gauche’, bougerGauche);  
boutonDroite = game.add.button(game.world.width - 64, game.world.height - 60, ‘bouton-droit’, bougerDroite);  
boutonFeu = game.add.button(game.world.centerX - 32, game.world.height - 60, ‘bouton-feu’, fireBullet);

With this fonction :  
function bougerGauche() {  
player.x -= 5;  
}  
function bougerDroite() {  
player.x += 5;  
}

But nothing append, the animation restart each time I press on screen.

Can you help me please ?

Problem is

```
game.input.onDown.add(startFullScreen, this);

```

Maybe you want `addOnce()`?
