我正在尝试使用cocos2d开发iphone游戏,我是初学者。 我试图在屏幕的上边界显示生命数量时遇到一些问题。所以我想从3个生命开始,并在每个错误中减少其中一个。这是我的代码
-(void)life {
NSMutableArray *position = [NSMutableArray
arrayWithObjects:@"460", @"440", @"420", nil];
spriteLifeArray = [[NSMutableArray alloc] init];
for (int i = 0; i<life; i++) {
spriteLife = [CCSprite spriteWithSpriteFrameName:@"cuore.png"];
[spriteLife setTag:i];
spriteLife.scale = 0.5;
spriteLife.position = ccp([[position objectAtIndex:i] floatValue], 305);
[self addChild:spriteLife];
[spriteLifeArray addObject:spriteLife];
}
}
这是我的游戏功能和删除生命的功能
-(void)gameOver:(int)value punteggio:(id)punti{
if (value == 1) {
// partita vinta
} else if(value == 2) {
if (life > 1) { // 1
life = life - 1;
for (CCSprite *spr in spriteLifeArray) {
if (life == spr.tag) {
[self removeChild:spr cleanup:YES];
[self actionBlink];
}
}
} else {
// partita persa
}
}
}
资源文件夹中存在名为“cuore.png”的文件,但是当我尝试编译时,在启动画面后应用程序崩溃。这是日志:

我想我犯了一个愚蠢的错误或遗漏了什么。有人可以帮帮我吗?
答案 0 :(得分:2)
您使用的CCSprite构造函数将在CCSpriteFrame缓存中查找CCSpriteFrame对象。如果你想要从名为'cuore.png'的文件中创建一个sprite,请使用构造函数:
CCSprite * spriteLife = [CCSprite spriteWithFile:@"cuore.png"];
精灵帧通常用于动画,或管理包含许多(有时不相关)纹理的大纹理地图集。

spriteWithSpriteFrameName通常与CCSpriteFrameCache一起使用,请使用'spriteWithFile'。 :)
