adding property for the group

[dudeperfect]

I have a group of boosts, and I would like to add a property for all of them. I have a method, that creates individual item:

dropFruit: function() {

        var fruit = this.boosts.create(40, -10, 'apple');

        this.physics.enable(fruit);

        fruit.body.gravity.y = 40;

        fruit.collided = false;

    },

 

then I have collision method:

    collisionWithBoost: function(croc, boost) {

        this.score += 10;

        boost.collided = true;

    },

 

it doesn't recognize this, even that second argument(boost) is from the boosts group. Is it possible to do thing like I tried to?
