Director Class

Extends EventTarget

Module: cc

ATTENTION: USE cc.director INSTEAD OF cc.Director.
cc.director is a singleton object which manage your game's logic flow.
Since the cc.director is a singleton, you don't need to call any constructor or create functions,
the standard way to use it is by calling:
- cc.director.methodName();
It creates and handle the main Window and manages how and when to execute the Scenes.

The cc.director is also responsible for:
- initializing the OpenGL context
- setting the OpenGL pixel format (default on is RGB565)
- setting the OpenGL buffer depth (default on is 0-bit)
- setting the color for clear screen (default one is BLACK)
- setting the projection (default one is 3D)
- setting the orientation (default one is Portrait)


The cc.director also sets the default OpenGL context:
- GL_TEXTURE_2D is enabled
- GL_VERTEX_ARRAY is enabled
- GL_COLOR_ARRAY is enabled
- GL_TEXTURE_COORD_ARRAY is enabled

cc.director also synchronizes timers with the refresh rate of the display.
Features and Limitations:
- Scheduled timers & drawing are synchronizes with the refresh rate of the display
- Only supports animation intervals of 1/60 1/30 & 1/15

Parameters
  • type String A string representing the event type being removed.
  • callback Function The callback to remove.
