Engine

For the game by Luke Drelick, see Engine (game).

An engine is one or more robots working to perform a specific task. Engines are the meat and potatoes of any decent game. Typical functions of gameplay engines include allowing the player to wield a sword, controlling jumping/gravity in a sidescrolling game, drawing and moving sprites on the screen, handling text boxes, status menus, and battles in an RPG, and simulating first-person perspective.
