-This tutorial shows how to move and animate SceneNodes. The
-basic concept of SceneNodeAnimators is shown as well as manual
-movement of nodes using the keyboard. We'll demonstrate framerate
-independent movement, which means moving by an amount dependent
-on the duration of the last run of the Irrlicht loop.
-
-Example 19.MouseAndJoystick shows how to handle other input than keyboard.
-
-As always, include the header files, use the irr namespace,
-and tell the linker to link with the .lib file.
