Once you’ve worked with mouse events, keyboard events are a breeze. In fact, key presses have fewer events associated with them than a mouse, though you can use multiple keys at a time for complex commands. But basically, a key possesses the down and up events.

An example of combination keys would be holding down the Shift key while using the arrows to make the object move faster.

In the following exercise, you will program keys to move an object in the 3D environment.

Let’s do it…

To move a 3D object, we can use the Transform class and modify the position of the model when a key is pressed. To achieve this, follow these steps:

1. In the Transform class, we will be adding a new function that will move an...
