Questions tagged [ccnode]

CCNode is the main element of a framework. Anything that gets drawn or contains things that get drawn is a CCNode. The most popular CCNodes are: CCScene, CCLayer, CCSprite, CCMenu.

The main features of a CCNode are:

  • They can contain other CCNode nodes (addChild, getChildByTag, removeChild, etc)
  • They can schedule periodic callback (schedule, unschedule, etc)
  • They can execute actions (runAction, stopAction, etc)
  • Some CCNode nodes provide extra functionality for them or their children.

Subclassing a CCNode usually means (one/all) of:

  • overriding init to initialize resources and schedule callbacks
  • create callbacks to handle the advancement of time
  • overriding draw to render the node

Features of CCNode:

  • position
  • scale (x, y)
  • rotation (in degrees, clockwise)
  • CCCamera (an interface to gluLookAt )
  • CCGridBase (to do mesh transformations)
  • anchor point
  • size
  • visible
  • z-order
  • openGL z position

Default values:

  • rotation: 0
  • position: (x=0,y=0)
  • scale: (x=1,y=1)
  • contentSize: (x=0,y=0)
  • anchorPoint: (x=0,y=0)

Limitations:

  • A CCNode is a "void" object. It doesn't have a texture
