执行结果：

2
并行动作和序列动作

CCSequence
中持续时间为全部动作累计的总合。CCSequence
中不能够

有CCRepeatForever
动作。

CCSpwan中持续时间为并行动作持续时间最长的决定。

3
假动作

CCCallFunc系列动作包含CCallFunc()、CCCallFuncN()、CCCallFuncND,以及CCCallFuncO四个动作，CCCallFunc系列动作的后缀”N”表示Node參数，指的是运行动作的对象，”D”表示Data參数，指的是用户自己定义的数据。”O”表示对象，指的是一个用户自己定义的CCObject參数。

在不同的情况下。我们能够依据不同的需求来选择不同的CCCallFunc动作。

typedef void (CCObject::*SEL_CallFunc)();

//无參类型

typedef void (CCObject::*SEL_CallFuncN)(CCNode*);

//传递CCNode *
类型变量

typedef void (CCObject::*SEL_CallFuncND)(CCNode*, void*);

//传递CCNode *
类型变量，和无类型变量

typedef void (CCObject::*SEL_CallFuncO)(CCObject*);

//传递CCObject *类型变量

#define callfunc_selector(_SELECTOR) (SEL_CallFunc)(&_SELECTOR)

CCCallFunc * func = CCCallFunc::create(this,

callfunc_selector(T13Action::funcCallBack));

CCCallFuncN * func = CCCallFuncN::create(this,

callfuncN_selector(T13Action::funcNCallBack));

CCCallFuncND * func = CCCallFuncND::create(this,

callfuncND_selector(T13Action::funcNDCallBack), (void *)"30");

CCArray * array = CCArray::create();

array->addObject(woman);

CCCallFuncO * func = CCCallFuncO::create(this,

callfuncO_selector(T13Action::funcOCallBack),(CCObject*)array);

CCSequence * seq = CCSequence::create(to, func, NULL);

man->runAction(seq);
