runAction不适用于来自CCSpriteBatchNode的sprites

问题描述

我使用Cocos2d 2.1rc0。

I am using Cocos2d 2.1rc0.

我有这个项目，当我没有使用CCSpriteBatchNode工作完美。然后我决定使用批处理节点来减少绘制调用，我的问题开始了。

I have this project that was working perfectly when I was not using CCSpriteBatchNode. Then I decided to use batch nodes to reduce draw calls and my problems started.

很多东西都不能正常工作。 reorderChild是一个。另一个是runAction，没有runAction Cocos是没用的。

A lot of stuff is not working well. reorderChild is one. Another one is runAction and without runAction Cocos is useless.

这是一个不使用batchNodes而不使用它的方法示例。

This is an example of a method that works without batchNodes and do not work with it.

// move/rotate all objects

for (int i=0; i<[allObjects count]; i++) {

        Card *object = [allObjects objectAtIndex:i];
        [object stopAllActions];

        CGPoint center = object.position;
        center.x = center.x + 100;
        center.y = center.y - 200;

        CCMoveTo *moveAction = [CCMoveTo actionWithDuration:0.3f position:ccp(center.x, center.y)];
        CCRotateTo *rotateAction = [CCRotateTo actionWithDuration:0.3 angle:0.0f];

        CCSpawn *action = [CCSpawn actions:moveAction, rotateAction, nil];

        [object runAction:[CCSequence actions: action,
                             [CCDelayTime actionWithDuration:0.1f],
                             nil]];
}

完全没有任何反应。

我试图消除CCSpanw和使用runAction直接只是与移动和没有工作。如果我使用常规精灵，它工作。

I have tried to eliminate the CCSpanw and use runAction directly just with move and nothing works. If I use regular sprites, it works.

该数组中的对象派生自基于CCSprite的类。

Objects in that array derive from a CCSprite based class.

是否有任何解决方法？

推荐答案

解决方案是将类转换为从数组提取的对象...

the solution is to cast the class to the object extracted from the array...

而不是

Card *object = [allObjects objectAtIndex:i];

此

Card *object = (Card *)[allObjects objectAtIndex:i];
