Remove child from group in collider

Hi, i am working in a game and cant remove child from a group… I have tried a lot of things and read a lot but cant find a solution. This is my actual collider code.

    this.physics.add.collider(
    this.player,
    this.enemie1,
    function (callback){
        this.enemie1.remove(this.enemie1.get(),true)
        this.player.destroy();
        let explosion = this.add.sprite(200, player.y, 'boom');
        explosion.play('explode');
        explosion.on('animationcomplete', function(listener){
            this.gameOver = true;
        }.bind(this))
    }.bind(this));   

I have tried this way too but this deletes more than one enemie

this.enemie1.children.iterate(function (child) {
                this.enemie1.remove(child,true);
            }.bind(this));

So, this is the solution :slight_smile:

    this.physics.add.collider(
        this.player,
        this.enemie1,
        function (player,enemie){
        enemie.destroy()
        player.destroy();
        let explosion = this.add.sprite(200, player.y, 'boom');
        explosion.play('explode');
        explosion.on('animationcomplete', function(listener){
            this.gameOver = true;
        }.bind(this))
    }.bind(this));
