我正在尝试为我的游戏创建暂停屏幕。游戏是在连续滚动背景(从上到下)与独立移动(从左到右)的障碍物的情况下开发的。

下面是代码:

暂停场景.h

@interface PauseScene : CCNode {}
@property (nonatomic, retain) HelloWorldScene *mainScene;
//+ (PauseScene *)scene;
- (id) init;
@end

暂停场景.m

@implementation PauseScene

- (id) init {
    if (self = [super init]) {
        // Adding RESUME and QUIT button and few others to make the whole Pause screen
    }
    return self;
}

// Called the method when Resume button is selected
- (void) Resume:(id) sender {
    //[[CCDirector sharedDirector] startAnimation];
    //[[CCDirector sharedDirector] resume];

    self.mainScene.userInteractionEnabled = YES;
    [self.mainScene removeChild: self];
    [self.mainScene StartGame]; // StartGame in MainScene contains the same code which commented out above, I will paste StartGame method later
}

// Quit method is called when the Quit button is pressed
- (void) Quit:(id) sender {
    //[[CCDirector sharedDirector] resume];
    //[[CCDirector sharedDirector] startAnimation];

    self.mainScene.userInteractionEnabled = YES;
    [self.mainScene removeChild: self];
    NSLog(@"Pre Reload", nil);
    //[self.mainScene scheduleOnce:@selector(ReloadGame) delay: 1.0f];
    [self.mainScene ReloadGame]; // Reload method contains the code commented above
}

@end

PauseScene 仅仅是节点类。

MainScene 文件中的 StartGame 和 ReloadGame 方法

- (void) StartGame {
    // Create and display HUD layer, like, scores, navigation buttons, etc.

    // Resuming the game
    //[[CCDirector sharedDirector] stopAnimation];
    [[CCDirector sharedDirector] resume];
    [[CCDirector sharedDirector] startAnimation];
}

- (void) ReloadGame {
    // Resume the game
    //[[CCDirector sharedDirector] stopAnimation];
    [[CCDirector sharedDirector] resume];
    [[CCDirector sharedDirector] startAnimation];

    [[CCDirector sharedDirector] replaceScene:[HelloWorldScene scene] withTransition:[CCTransition transitionFadeWithDuration:1.0f]];
}

暂停按钮显示在 MainScene 的 HUD 层,所以,当点击暂停按钮时,我们会暂停游戏并显示 PauseScene

- (void)onPauseClicked:(id)sender {
    // Code to display the pause node of this scene

    // Pause the game
    [[CCDirector sharedDirector] stopAnimation];
    [[CCDirector sharedDirector] pause];
}

当我注释掉它stopAnimation并分开时pause,暂停和恢复工作完美。但是当我实现其中任何一个时,在退出游戏的时候,replaceScene它并没有以某种方式工作。我认为这是因为游戏进入了暂停模式,但即使我使用调度程序在 5-10 秒的延迟上调用 replaceScene,它也无法正常工作。

如果我不使用这些stopAnimationand ,即使我的游戏暂停pause,一些给出的精灵也不会被暂停并继续。CCAction

感谢您的帮助,因为我正在使用 Cocos2d 3.0 并且无法找到任何适当的帮助。

感谢@LearnCocos2D 的提示。

我只需删除代码stopAnimationstartAnimationpauseresume方法即可成功实现暂停/恢复。paused我只是用节点的属性替换了这些。

要暂停游戏,需要为游戏中的每个节点设置 paused = YES 并反向恢复。
