Question

尝试在延迟后运行GoToGameOverScene（this）函数。我得到“无视值，因为它应该是”

// set up the time delay
DelayTime *delayAction = DelayTime::create(2.5f);
// perform the selector call
CallFunc *callSelectorAction = CallFunc::create(this, SEL_CallFunc(GoToGameOverScene(this)));
// run the action
this->runAction(Sequence::create(delayAction, callSelectorAction, NULL));

其他功能如下：

void GameScreen::GoToGameOverScene(cocos2d::Ref *pSender)
{
    auto scene = GameOver::createScene();

    Director::getInstance()->replaceScene(scene);
}

Answer 1

SpriteNM->runAction(Sequence::create(DelayTime::create(1.0),CallFunc::create(std::bind(&ClassNM::MethodNM, this,IfParameter)),NULL));

Answer 2

更改此

CallFunc *callSelectorAction = CallFunc::create(this, SEL_CallFunc(GoToGameOverScene(this)));

到

CallFunc *callSelectorAction = CallFunc::create(this, callfunc_selector(ClassName::GoToGameOverScene));

干杯...

Answer 3

如果您使用的是v 3.3，则必须以这种方式使用它：

CallFunc *callSelectorAction = CallFunc::create(this, CC_CALLBACK_1(ClassName:GoToGameOverScene,this));

其中，CC_CALLBACK_1在您的函数有一个参数时使用。

Answer 4

this->runAction(Sequence::create(DelayTime::create(1.0),CallFunc::create(std::bind(&ClassName::MethodName, this,IfParameter)),NULL));

或

SpriteName->runAction(Sequence::create(DelayTime::create(1.0),CallFunc::create(std::bind(&ClassName::MethodName, this,IfParameter)),NULL));

在cocos2dx中延迟后调用一个函数
