javascript - Phaser Tilemaps -

have tried code below , tileset doesn't load.

  this.game.physics.startsystem(phaser.physics.arcade);    map = game.add.tilemap('tilemap');      map.addtilesetimage('floor', 'tiles');      layer = map.createlayer('groundlayer');      layer.resizeworld();

found code worked

this.game.physics.startsystem(phaser.physics.arcade);    this.map = game.add.tilemap('tilemap');      this.map.addtilesetimage('floor', 'floor');      this.layer = this.map.createlayer('groundlayer');      game.physics.enable(this.map, phaser.physics.arcade);      this.map.setcollisionbetween(0, 1, true, "groundlayer");      this.layer.resizeworld();
