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]];
}
}
