Cocos2d-x::Actions

Actions are orders given to a CCNode object. These actions usually modify some of the object's attributes like position, rotation, scale, etc. If these attributes are modified during a period of time, they are CCIntervalAction actions, otherwise they are CCInstantAction actions. For example, the CCMoveBy action modifies the position property during a period of time, hence, it is a subclass of CCIntervalAction.

You can run TestCpp->Actions test to see the action's visual effects. And cocos2d-x/samples/Cpp/TestCpp/Classes/ActionsTest, ActionsEaseTest are good sample codes for the usage.

Example:

// Move a sprite 50 pixels to the right, and 10 pixels to the top over 2 seconds.
2CCActionInterval*  actionBy = CCMoveBy::create(2, ccp(50,10));

The CCIntervalAction actions have some interesting properties: They can be accelerated using the time-altered actions

• CCEaseIn
• CCEaseOut
• CCEaseInOut
• CCSpeed Etc. (See the ActionsEaseTest.cpp example for more info)

You can pause/resume all actions by using the CCActionManager:

// Pause actions
CCDirector *director = CCDirector::sharedDirector();
m_pPausedTargets = director->getActionManager()->pauseAllRunningActions();
// resume actions
CCDirector *director = CCDirector::sharedDirector();
director->getActionManager()->resumeTargets(m_pPausedTargets);

###Basic Actions Basic actions are the ones that modify basic properties like:

####Position

• CCMoveBy
• CCMoveTo
• CCJumpBy
• CCJumpTo
• CCBezierBy
• CCBezierTo
• CCPlace

####Scale

• CCScaleBy
• CCScaleTo

####Rotation

• CCRotateBy
• CCRotateTo

####Visibility

• CCShow

• CCHide

• CCBlink

• CCToggleVisibility

• Opacity

• CCFadeIn

• CCFadeOut

• CCFadeTo

####Color

• CCTintBy
• CCTintTo

Example：

CCSprite *sprite = CCSprite::create("Images/grossini.png");
sprite->setPosition(ccp(100, 100));
addChild(sprite);

CCMoveBy* act1 = CCMoveBy::create(0.5, ccp(100, 0));
sprite->runAction(CCRepeat::create(act1, 1));
