为什么我的变量没有在Cocos2d中设置？

在我的游戏管理单独的对象创建：为什么我的变量没有在Cocos2d中设置？

// Load levels 
     // Create array property to store level objects 
     self.levels = [[[NSMutableArray alloc] init] autorelease]; 
     //Create 2 level objects with spawnRates 
     Level *level1 = [[[Level alloc] initWithLevelNum:1 spawnRate:10000 bgImageName:@"Icon.png"] autorelease]; 
     Level *level2 = [[[Level alloc] initWithLevelNum:2 spawnRate:10000 bgImageName:@"Icon.png"] autorelease]; 
     Level *level3 = [[[Level alloc] initWithLevelNum:3 spawnRate:80 bgImageName:@"Icon.png"] autorelease]; 
     Level *level4 = [[[Level alloc] initWithLevelNum:4 spawnRate:80 bgImageName:@"Icon.png"] autorelease]; 
     Level *level5 = [[[Level alloc] initWithLevelNum:5 spawnRate:2 bgImageName:@"Icon.png"] autorelease]; 
     Level *level6 = [[[Level alloc] initWithLevelNum:6 spawnRate:1 bgImageName:@"Icon.png"] autorelease]; 
     //Put level objects into array property 
     [_levels addObject:level1]; 
     [_levels addObject:level2]; 
     [_levels addObject:level3]; 
     [_levels addObject:level4]; 
     [_levels addObject:level5]; 
     [_levels addObject:level6]; 
     //Set current level index to 0 
     self.curLevelIndex = 0;

并进一步向下行，我实现方法由层被称为像这样：

- (Level *)curLevel { 
    NSLog(@"curLevelIndex is %d", _curLevelIndex); 
    //returns object at current level index where at start, first slot [0] = spawnrate = 1 
    return [_levels objectAtIndex:_curLevelIndex]; 
} 

- (void)restartGame { 
    _curLevelIndex = 0; 
    [self nextLevel]; 
} 

- (void)levelComplete { 
    NSLog(@"curLevel spawnRate is %d", [self curLevel].spawnRate); 

    //Increase currentlevelindex 
    _curLevelIndex++; 

    if (_curLevelIndex >= [_levels count]) { 
     _curLevelIndex = 0; 
     NSLog(@"resetting levels"); 
    } else { 
     //make it faster 
     //NSLog(@"current level %d", [[_levels objectAtIndex:_curLevelIndex].spawnRate ]; 
     NSLog(@"new level %d", _curLevelIndex); 
    } 

}

请原谅所有NSLogs但我要去疯狂试图找出为什么我的spawnRate没有被改变。在我的游戏的更新方法中，我这样做：

if (timeSinceLastRateBump > 3) { 
     NSLog(@"DIFFICULTY INCREASES NOW>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"); 
     [[GameManager sharedGameManager] levelComplete]; 
     timeSinceLastRateBump = 0; 
    }

这就是每秒或多或少地调用。现在即时得到这个在我的NSLog：

这证明curLevelIndex从0到1增加至2但spawnRate保持为0，为什么？

，而不是在你的日常levelComplete

看不到任何改变spawnRate值的代码 – Morion

为spawnRate显示你的Level类（setters，getters） – YvesLeBorg

为每个Level实例创建不同的spawnRate。我创建了6个Level实例，并将它们放入self.levels数组中。当调用levelComplete方法时，curLevelIndex获取++，因此返回[self.levels objectAtIndex：_curLevelIndex];方法 - （Level *）curLevel;应该在新的curLevelIndex处返回Level。 – marciokoko

，：

NSLog(@"new level %d", _curLevelIndex);

做的事：在日志

Level* current = [self curLevel]; 
NSLog(@"current level no : %d , spw rate : %f",current.levelNumber,current.spawnRate]; 
// *** WAG for the getters.

和断点。如果电流为零，请指出。如果没有，请检查var并查看该对象中的产卵率。

我仍然得到0 spawnRate。目前是不是零，我得到我的水平与我分配spawnRate和一切:( – marciokoko

杜赫...使用％f记录你的产卵率，你记录什么不是你有什么。 – YvesLeBorg

中的代码：

NSLog(@"curLevel spawnRate is %d", [self curLevel].spawnRate);

％d被用于双精度值，而不是一个浮子。将其更改为％f。
