n Reserving a space for the game engine to draw the game world and accept input,
such as mouse clicks or drags to move the view or modify actors.
n Displaying and managing a complete list of all available game assets, such as
textures, audio files, Lua scripts, and so on.
n Reading actor information from the game engine and sending any changes to
actor components back to the game engine.
n Displaying a complete list of all the actors in the current scene and allowing
them to be selected for modification.
n Displaying the components of the currently selected actor so it can be modified.
n Displaying a menu for opening levels, creating new components on selected
actors, and so on.

I ' ll cover each of these areas in the next few sections.
