Cocos2D - 在幾個CCSprites上使用循環重複動作不能按預期工作......爲什麼？

Question

這工作：

for (Object *oneObj in allObjects) { 

    id moveAction = [CCMoveTo actionWithDuration:0.3f position:ccp(tx, ty)]; 
    id rotateAction = [CCRotateTo actionWithDuration:0.3 angle:0.0f]; 

    id action = [CCSpawn actions:moveAction, rotateAction, nil]; 
    id sequence = [CCSequence actions: action, 
            [CCDelayTime actionWithDuration:0.1f], 
            nil]; 

    [oneObj runAction:sequence]; 
} 

這不工作（只是一個對象被這個感動）：

id moveAction = [CCMoveTo actionWithDuration:0.3f position:ccp(tx, ty)]; 
id rotateAction = [CCRotateTo actionWithDuration:0.3 angle:0.0f]; 

id action = [CCSpawn actions:moveAction, rotateAction, nil]; 
id sequence = [CCSequence actions: action, 
          [CCDelayTime actionWithDuration:0.1f], 
          nil]; 

for (Object *oneObj in allObjects) { 
    [oneObj runAction:sequence]; 
} 

爲什麼呢？

Answer 1

因爲一個動作只能在一個節點上運行。你有那麼每個對象都運行自己的序列的拷貝複製序列：

[oneObj runAction:[sequence copy]];
