Use function one time when collided

[AbdSab]

Hi all
 
I have a little problem, i have set the collision of two spritse:

game.physics.arcade.collide(sprite1, sprite2, this.collisionSprite, null, this);collisionSprite: function(){      variable++;}

The problem is when the sprite1 collide with sprite2 the variable keep increasing, i want to increase the variable just one time, is there any solution please.

 

And thank's for any help
