ccTouch事件在所有相同的精靈（精靈陣列）

Question

我剛剛開始從一個教程學習Cocos2d。我想隨機飛行'蝙蝠'，當我觸摸屏幕上的任何地方時，所有蝙蝠聚集在我的觸摸位置，並且他們又開始隨機飛行。
這裏是我的代碼：

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

    [[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"Bat.plist"]; 

    //Bats Array Initialization 
    bats = [[NSMutableArray alloc] init]; 

    //Add bats using a batch node. 
    CCSpriteBatchNode *batch1 = [CCSpriteBatchNode batchNodeWithFile:@"Bat.png" capacity:10]; 
    [self addChild:batch1 z:2 tag:TAG_BATS]; 

    //Make them start flying up. 
    for(int x=0; x<5; x++){ 
     //Create SimpleAnimObject of bat 
     bat1 = [SimpleAnimObj spriteWithBatchNode:batch1 rect:CGRectMake(0,0,48,48)]; 
     [batch1 addChild:bat1]; 
     [bat1 setPosition:ccp(arc4random()%900+40, arc4random()%600+50)]; 
     [bat1 setScale:0.6f]; 

     float flappingSpeed = [self makeBatFlyUp:bat1]; 
     bat1.velocity = ccp((arc4random()%1000)/500 + 0.2f, 0.1f/flappingSpeed); 

     [bats addObject:[NSValue valueWithPointer:bat1]]; 
     [bat1 retain]; 

     //Set the bat's direction based on x velocity. 
     if(bat1.velocity.x > 0){ 
      bat1.flipX = YES; 
     } 
    } 

    self.isTouchEnabled = YES; 
    [self schedule:@selector(step:)]; 


} 
return self; 
} 
-(float)makeBatFlyUp:(SimpleAnimObj*)bat { 
CCSpriteFrameCache * cache = [CCSpriteFrameCache sharedSpriteFrameCache]; 

float delay = (float)(arc4random()%5+5)/150; 
CCAnimation *animation = [[CCAnimation alloc] initWithName:@"simply_bat_fly" delay:delay]; 

int num = arc4random()%9+1; 
for(int i=1; i<=9; i+=1){ 
    [animation addFrame:[cache spriteFrameByName:[NSString stringWithFormat:@"b%i.tiff",num]]]; 
    num++; 
    if(num > 9){ num = 1; } 
}  

[bat stopAllActions]; 
[bat runAction:[CCRepeatForever actionWithAction: [CCAnimate actionWithAnimation:animation]]]; 

bat.animationType = BAT_FLYING_UP; 

return delay; 
} 

在觸摸事件：

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{ 

CGPoint touchLocation = [touch locationInView:[touch view]]; 
touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation]; 
touchLocation = [self convertToNodeSpace:touchLocation]; 

float velocityBat = 1024/3.0 ; 

CGPoint moveDifference = ccpSub(touchLocation,bat1.position); 
float distanceMove = ccpLength(moveDifference); 
float moveduration = distanceMove/ velocityBat; 

// here i have to use Array but i don't know how to use array to access all same sprites. 

self.moveAction = [CCSequence actions:       
        [CCMoveTo actionWithDuration:moveduration position:touchLocation], 
        [CCCallFunc actionWithTarget:self selector:@selector(bearMoveEnded)], 
        nil 
        ]; 
[bat1 runAction:moveAction]; 

return YES; 
} 

蝙蝠是正常飛行，但是當我在屏幕上只觸摸蝙蝠跟着我的觸摸事件別人都保留隨機移動。
任何人都可以幫我嗎？如果我錯過任何事情或者我錯了什麼地方？

謝謝！

您只有一個對正在使用的蝙蝠的引用：bat1變量。你需要使用蝙蝠陣列來訪問所有的蝙蝠。

此外，擺脫[bat1 retain]線，因爲通過將每個蝙蝠添加到蝙蝠陣列它已被保留。通過調用addChild:node將Cocos節點作爲父節點的子節點時，也會保留Cocos節點。
