由于某种原因,我在 +[CCSprite spriteWithSpriteFrameName:] 中遇到断言失败。

我基本上是在尝试“更新PinkBerries”,或者换句话说,创建更多的精灵“浆果”以添加到屏幕上。他们是我游戏中的“敌人”。

这是我的代码:

- (id) init
{
    if((self = [super init]))
    {

        CCLOG(@"%@ init", NSStringFromClass([self class]));

        self.touchEnabled = YES;

        [self scheduleUpdate];
    }
    return self;
}

-(void)updatePinkBerries:(ccTime)dt
{
    CGSize winSize = [CCDirector sharedDirector].winSize;

    double curTime = CACurrentMediaTime();

    if (curTime > _nextPinkBerrySpawn)
    {
        // Figure out the next time to spawn an asteroid
        float randSecs = randomValueBetween(0.20, 1.0); _nextPinkBerrySpawn = randSecs + curTime;

        // Figure out a random Y value to spawn at
        float randY = randomValueBetween(0.0, winSize.height);

        // Figure out a random amount of time to move from right to left
        float randDuration = randomValueBetween(2.0, 10.0);

        // Create a new asteroid sprite
        CCSprite *pinkBerry = [CCSprite spriteWithSpriteFrameName:@"ship.png"]; [_batchNode addChild:pinkBerry];

        // Set its position to be offscreen to the right
        pinkBerry.position = ccp(winSize.width + pinkBerry.contentSize.width/2, randY);

        // Move it offscreen to the left, and when it's done, call removeNode
        [pinkBerry runAction:
         [CCSequence actions:
          [CCMoveBy actionWithDuration:randDuration position:ccp(-winSize.width- pinkBerry.contentSize.width, 0)],
          [CCCallFuncN actionWithTarget:self selector:@selector(removeNode:)], nil]];
    }
}

我从 Ray Wanderlich 教程中认识到这一点。因为他的作品与您可能使用的不同,您应该创建自己的文件CCSpriteBatchNode和随附的plist文件,以免他项目中的项目名称与您的项目名称混淆。
