ios - 带参数的顺序调用方法 cocos2d-x v3.1

Question

我只想调用一个接受 Sprite 类型参数的方法 -

到目前为止我的代码 -

auto obstacleSprite   =   CCSprite::create(OBSTACLE_SPRITE);
obstacleSprite->setPosition(Vec2(visibleSize.width*0.25,visibleSize.height*0.15));
this->addChild(obstacleSprite);

Sequence *seq   =   Sequence::create(DelayTime::create(randomDelay),CallFunc::create( std::bind(&GamePlayScene::createObstacles,this) ), NULL);

this->runAction(seq);

要调用的方法

void GamePlayScene::createObstacles(Sprite *spriteObj){
    CCLOG("HA HA HA");
}

我不知道如何在 CallFunc 中传递 Sprite(obstacleSprite) 对象。请帮忙。

你可以这样做(我现在无法测试):

Sequence *seq = Sequence::create(DelayTime::create(randomDelay), CallFunc::create(std::bind(&GamePlayScene::createObstacles, this, obstacleSprite)), NULL);

此外，请查看:“tests/cpp-tests/Classes/ActionsTest/ActionsTest.cpp”，第 981 和 1010 行。
