/**
|
|
A CCCamera is used in every CCNode.
|
|
Useful to look at the object from different views.
|
|
The OpenGL gluLookAt() function is used to locate the
|
|
camera.
|
|
|
|
If the object is transformed by any of the scale, rotation or
|
|
position attributes, then they will override the camera.
|
|
|
|
IMPORTANT: Either your use the camera or the rotation/scale/position properties. You can't use both.
|
|
World coordinates won't work if you use the camera.
|
|
|
|
Limitations:
|
|
|
|
- Some nodes, like CCParallaxNode, CCParticle uses world node coordinates, and they won't work properly if you move them (or any of their ancestors)
|
|
using the camera.
|
|
|
|
- It doesn't work on batched nodes like CCSprite objects when they are parented to a CCSpriteBatchNode object.
|
|
|
|
- It is recommended to use it ONLY if you are going to create 3D effects. For 2D effects, use the action CCFollow or position/scale/rotate.
