                break;
                case 37: //rotate anti-clockwise
                controller.tryRotate(1, Model.blockData, Model.boardData);
                break;
                case 39: //rotate clockwise
                controller.tryRotate(-1, Model.blockData, Model.boardData);
                break;
                }
                Model.painter.drawBlock(Model.blockData);
            }

    }
    
}

here it includes two parts:

one is for controller setting, defining the key Events for each of controlling of the game;

The other is game iteration, i use enter frame event as my looping base, of course, you can also use Timer class to build the iteration if you prefer. About the details of game logic, you can read more in my coding.
