爲什麼我的變量沒有在Cocos2d中設置？

在我的遊戲管理單獨的對象創建：爲什麼我的變量沒有在Cocos2d中設置？

// 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;

並進一步向下行，我實現方法由層被稱爲像這樣：

- (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); 
    } 

}

請原諒所有NSLogs但我要去瘋狂試圖找出爲什麼我的spawnRate沒有被改變。在我的遊戲的更新方法中，我這樣做：

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

這就是每秒或多或少地調用。現在即時得到這個在我的NSLog：

這證明curLevelIndex從0到1增加至2但spawnRate保持爲0，爲什麼？

，而不是在你的日常levelComplete

看不到任何改變spawnRate值的代碼 – Morion

爲spawnRate顯示你的Level類（setters，getters） – YvesLeBorg

爲每個Level實例創建不同的spawnRate。我創建了6個Level實例，並將它們放入self.levels數組中。當調用levelComplete方法時，curLevelIndex獲取++，因此返回[self.levels objectAtIndex：_curLevelIndex];方法 - （Level *）curLevel;應該在新的curLevelIndex處返回Level。 – marciokoko

，：

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

做的事：在日誌

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

和斷點。如果電流爲零，請指出。如果沒有，請檢查var並查看該對象中的產卵率。

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

杜赫...使用％f記錄你的產卵率，你記錄什麼不是你有什麼。 – YvesLeBorg

中的代碼：

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

％d被用於雙精度值，而不是一個浮子。將其更改爲％f。

爲什麼我的變量沒有在Cocos2d中設置？
