首先看一张图片,表示了CCCallFunc的继承关系:
[cpp]
CCSequence::actions(CCCallFunc::actionWithTarget(this,callfunc_selector(ExtendActionLayer::onCallBack1)));
void ExtendActionLayer::onCallBack1()
{
flight->runAction(CCTintBy::actionWithDuration(0.5f,255));
}
2、CCCallFuncO,回调,O表示CCObject,CCCallFunco可以带CCObject参数的函数
[cpp]
CCSequence::actions(CCCallFuncO::actionWithTarget(this,callfuncO_selector(ExtendActionLayer::onCallBack2),CCInteger::create(2));
void ExtendActionLayer::onCallBack2(CCObject* data)
{
CCInteger* num = dynamic_cast<CCInteger*>(data);
pSender->runAction(CCTintBy::actionWithDuration(num->getValue(),255));
}
3、CCCallFuncN,回调,N表示CCNode,表示可以传递Node*类型
[cpp]
CCSequence::actions(CCCallFuncN::actionWithTarget(this,callfuncN_selector(ExtendActionLayer::onCallBack3)));
void ExtendActionLayer::onCallBack3(CCNode* pSender)
{
// 在这个例子里,pSender就是flight,因为是他执行了那个actionF
pSender->runAction(CCTintBy::actionWithDuration(1.0f,255));
}
4、CCCallFuncND,回调,ND表示CCNode和Data,可以传递对象本身和一个void*类型参数,void*表示可以是任意类型的参数
[cpp]
CCSequence::actions(CCCallFuncND::actionWithTarget(this,callfuncND_selector(ExtendActionLayer::onCallBack4),(void *)2));
void ExtendActionLayer::onCallBack4(CCNode* pSender,void* pData)
{
pSender->runAction(CCTintBy::actionWithDuration(static_cast<float>((int)pData),255));
}
