以毫秒为单位获取当前时间 Cocos2d [英] Getting current time in milliseconds Cocos2d

问题描述

我已经尝试谷歌搜索，但仍然找不到最佳答案.

I've tried to google around but I still can't find the best answer.

我想要的很简单，我只想以毫秒为单位获取当前时间.

All I want is very simple, I just want to get the current time in milliseconds.

如何在 cocos2d 中做到这一点?

How can I do that in cocos2d?

推荐答案

一、类变量:

CGFloat gameTime;

然后在你的类中初始化:

Then in your class initialize:

[self scheduleUpdate];

最后，在你还在上课的时候:

Finally, while still in your class:

- (void) update:(ccTime)delta {
    gameTime += delta;
}

delta 是自上次调用更新以来的毫秒数.将 gameTime 保存在数据库中的某个位置，以作为终生游戏时间.

delta is the milliseconds since the last call of update. Save gameTime somewhere in a database for lifetime gameTime.
