Detailed Description
An instance of a subclass of CC3NodeAnimation manages the animation of nodes.
It is held in the animation property of the node itself, and is activated when the establishAnimationFrameAt: method is invoked on the node.
A single CC3NodeAnimation instance can be shared by multiple nodes. This is a typical situation when creating many copies of a node that is animated.
CC3NodeAnimation is an abstract class. Subclasses define concrete animation data storage.
Member Function Documentation
| + (id) animationWithFrameCount: | (GLuint) | numFrames |
Allocates and initializes an autoreleased instance to animate with the specified number of animation frames.
| - (void) establishFrameAt: | (ccTime) | t | |
| forNode: | (CC3Node *) | aNode | |
Updates the location, rotation, quaternion, and scale of the specified node based on the animation frame located at the specified time, which should be a value between zero and one, with zero indicating the first animation frame, and one indicating the last animation frame.
Only those properties of the node for which there is animation data will be changed. If the shouldInterpolate property is set to YES, linear interpolation of the frame data is performed, based on the frameCount and the specified time.
| - (id) initWithFrameCount: | (GLuint) | numFrames |
Initializes this instance to animate with the specified number of animation frames.
Property Documentation
- (GLuint) frameCount [read, assign] |
The number of frames of animation.
- (BOOL) isAnimatingLocation [read, assign] |
Indicates whether location data is available for animation.
Default returns NO. Subclasses with data should override appropriately.
- (BOOL) isAnimatingQuaternion [read, assign] |
Indicates whether rotation quaternion data is available for animation.
Default returns NO. Subclasses with data should override appropriately.
- (BOOL) isAnimatingRotation [read, assign] |
Indicates whether rotation data is available for animation.
Default returns NO. Subclasses with data should override appropriately.
- (BOOL) isAnimatingScale [read, assign] |
Indicates whether scale data is available for animation.
Default returns NO. Subclasses with data should override appropriately.
- (BOOL) shouldInterpolate [read, write, assign] |
Indicates whether this animation should interpolate between frames, for accuracy.
The initial value of this property is YES.
