Overlap objects

Phaser 3
1

Is there a way no not let objects spawn above each other?

    //criar 50 zonas de objetos
    this.objects = this.physics.add.group({
        classType: Phaser.GameObjects.Sprite
      });

    for(var i = 0; i<600; i++){

        var x = Phaser.Math.RND.between(50, this.physics.world.bounds.width - 100);
        var y = Phaser.Math.RND.between(50, this.physics.world.bounds.height - 100);

        //if para evitar criar objetos na areia e nos obstaculos
        if(!this.obstaculos.getTileAtWorldXY(x, y) && !this.areia.getTileAtWorldXY(x, y)){

            this.objects.create(x, y, this.getObjectSprite());

        }else{
            
           // console.log('Colision with layers');
            i--;

        }
    }
