计划选择器错误

标签: c++ windows-8 cocos2d-x

我正在尝试将我的iPhone应用程序移植到Windows 8,我对此行有问题(它的目标是c):

[self schedule:@selector(fire:)];

c ++上的等价物应该是:

this->schedule(schedule_selector(AirScene::fire));

AirScene是我班级的名称,但我在Visual Studio 2012中返回此错误:

error C2064: term does not evaluate to a function taking 1 arguments

因此,换句话说,找不到功能计划(选择器)。这很奇怪,因为我对非计划方法没有任何问题,你有什么想法吗?

<强>固定。

用于Windows 8模板的cocos 2d版本是旧版本,因此安排选择器的好方法是:

CCScheduler::sharedScheduler()->scheduleSelector(schedule_selector(AirScene::fire), this, 0, false);
