Gocos2D

Introduction:

Gocos2D is a Google Go(lang) game development library based on the popular Cocos2D video game sdk. For those who are unfamiliar with Cocos2D, the design philosophy behind the project is that it intends to simplify game development. One way it does this is by providing objects called singletons that handle openGL commands and initialization for you; effectively simplifying the game development experience drastically.

Here is an example of what the Cocos2D/Gocos2D experience is like in regards to the singletons.

The main singleton is called the director. The director's job is to handle your games scenes for you. You can pass the director a scene that contains all your sprites and scene related logic; then the director pushes it onto the scene stack. The director will then draw your scene to the openGL context while updating your game logic for you. If the director is commanded to swap scenes with another, for instance when you beat level 1 and need to start level 2, the director pops level 1 off the stack. Which the garbage collector then collects the popped scene and the director starts the entire process all over again but this time with the current scene pointer pointing at level 2's scene.

Variables

var Director = new(director)

The Director is a singleton that is designed to simplify how you manage your game. It is used to initialize a openGL context and It maintains a stack of scenes. You are able to update and draw your scenes directly by calling Director.Update and Director.Draw in your game loop.
