|

@brief CCActionManager is a singleton that manages all the actions.
|
|
Normally you won't need to use this singleton directly. 99% of the cases you will use the CCNode interface,
|
|
which uses this singleton.
|
|
But there are some cases where you might need to use this singleton.
|
|
Examples:
|
|
- When you want to run an action where the target is different from a CCNode.
|
|
- When you want to pause / resume the actions
