如何檢查是否有東西在移動？

Question

我正在製作一個有敵人拍攝東西的cocos2d應用程序。很多時候，一旦一個精靈被編程移動到一個隨機的地方，一旦它的隊友被殺死，就直接進入他自己種類的其他敵人的交火。我該如何做一些事情來檢查它是否正在移動，因爲大部分時間，遊戲看起來像試圖自殺的敵人。我希望敵人能夠自己，但不是在他們移動時。

-(void)enemy2{ 

    enemy2 = [CCSprite spriteWithFile:@"enemy2.png"]; 
    int d = arc4random()%480+480; 
    int o = arc4random()%320+320; 
    x = arc4random()%480; 
    if(x <= 480 && x>= 460){ 
    x=x-100; 
} 
if(x <= 100){ 
    x = x+50; 
} 

y = arc4random()%320; 
if(y <=320 && y >= 290){ 
    y = y-100; 
} 
if(y < 100){ 
    y = y + 100; 
} 
enemy2.position = ccp(o,d); 

xc = x; 
te = y; 
    [enemytwo addObject :enemy2]; 




[self addChild:enemy2]; 

for(CCSprite *enetw in enemytwo){ 

    CCRotateBy *rotation = [CCRotateBy actionWithDuration:15 angle:1080]; 
    CCRepeatForever * repeatforever = [CCRepeatForever actionWithAction:rotation]; 

    int f = arc4random()%480; 
    int s = arc4random()%320;  
    if(f <= 480 && s>= 460){ 
     f=f-100; 
    } 
    if(f <= 100){ 
     f = f+50; 
    } 

    s = arc4random()%320; 
    if(s <=320 && s >= 290){ 
     s = s-100; 
    } 
    if(s < 100){ 
     s = s + 100; 
    } 

    CCMoveTo *move = [CCMoveTo actionWithDuration:0.8 position:ccp(f,s)]; 
    [enetw runAction: repeatforever]; 
    [enetw runAction:[CCSequence actions:move, nil]]; 



}

Answer 1

我會創建一個存儲BOOL是否而不是角色正在移動。只要角色即將移動，請將BOOL設置爲YES。由於您正在使用動作來移動精靈，因此您可以使用一系列動作，其中第一個動作是移動動作，然後第二個動作是將您的BOOL設置爲NO的塊。這樣，一旦移動動作完成，它就會被存儲起來供以後參考。它看起來像這樣。

BOOL isObjectMoving;將這個其他地方，可能在實體子類或任何其他

CCMoveTo *move = [CCMoveTo actionWithDuration:0.8 position:ccp(f,s)]; 
CCCallBlock *end = [CCCallBlock actionWithBlock:^{ 
    isObjectMoving = NO; 
}]; 

isObjectMoving = YES; //Set it to YES until the movement action finishes and sets it back to NO 

[yourObject runAction:[CCSequence actionOne:move actionTwo:end]];
