/** @class ActionManager
@brief ActionManager 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 Node interface,
2010-08-05 14:37:36 +08:00
which uses this singleton.
But there are some cases where you might need to use this singleton.
Examples:
2021-12-25 10:04:45 +08:00
- When you want to run an action where the target is different from a Node.
- When you want to pause / resume the actions.
