Detailed Description

An interval action is an action that takes place within a certain period of time.

It has an start time, and a finish time. The finish time is the parameter duration plus the start time.

These CCActionInterval actions have some interesting properties, like:

• They can run normally (default)
• They can run reversed with the reverse method
• They can run with the time altered with the Accelerate, AccelDeccel and Speed actions.

For example, you can simulate a Ping Pong effect running the action normally and then running it again in Reverse mode.

Example:

CCAction *pingPongAction = CCSequence::actions(action, action->reverse(), NULL);
