Chú ý rằng sự kiện này CLICK không phải là một sự kiện MouseEvent nhưng là một sự kiện InteractiveScene3Devent Papervision3D. Trong tất cả các cách khác, các cú pháp nên quen thuộc với bạn. Chẳng bao lâu bạn sẽ tạo ra onClick () chức năng, và sau đó bạn sẽ sử dụng chức năng để động khối lập phương. | Notice that this CLICK event is not a MouseEvent event but is a Papervision3D InteractiveScene3Devent event. In all other ways the syntax should be familiar to you. Soon you will create the onClick function and then later you will use that function to animate the cube.

To be able to test what you have done so far you will need to create the shell for the onClick onKeyD and onKeyU functions.
