Question

我有这个：

-(void)fadeBackground
{
    ccColor4B color = {0,0,0,255};
    CCLayerColor *fadeLayer = [CCLayerColor layerWithColor:color];
    [self addChild:fadeLayer z:7];
    fadeLayer.opacity = 0;


    id fade   = [CCFadeTo actionWithDuration:1.0f opacity:200];//200 for light blur
    id calBlk = [CCCallBlock actionWithBlock:^{
        //show pause screen buttons here
        //[self showPauseMenu];
    }];
    id fadeBack = [CCFadeTo actionWithDuration:2.0f opacity:0];

    id sequen = [CCSequence actions:fade, calBlk, fadeBack, nil];

    [fadeLayer runAction:sequen];

}

如何在fadein发生时停止操作并在fadeBack发生时恢复它们？

Answer 1

[[CCDirector sharedDirector] pause];＆amp; [[CCDirector sharedDirector] resume];将在所有Sprite / Layers或任何其他cocos2d节点中暂停和恢复调度程序和操作。

如果您想暂停/恢复特定CCLayer及其包含的子项

////for pausing
[myLayer pauseSchedulerAndActions];
for(CCNode *child in myLayer.children){
[child pauseSchedulerAndActions];
}

///for resuming
[myLayer resumeSchedulerAndActions];
for(CCNode *child in myLayer.children){
[child resumeSchedulerAndActions];
}

Answer 2

要暂停，您可以使用此通话，需要为游戏中的每个菜单调用相同的内容。

   [self  pauseSchedulerAndActions];
   [menu  pauseSchedulerAndActions];

要恢复：

  [self resumeSchedulerAndActions];
  [menu  pauseSchedulerAndActions];

如何在消失cclayer然后在cocos2d中恢复游戏时暂停所有操作？
