Iphone Sprite.rotation在box2d中不工作

我有一个精灵数组，允许用户在ccTouchesMoved中移动

当用户选择了一个精灵（通过触摸它）时，他们可以选择使用ccTouchesMoved方法旋转精灵，直到取消选择旋转功能为止

精灵可以正确旋转，但是我有另一种方法，可以在精灵周围创建边，这样它们就可以进行碰撞等等

当调用此方法时，它将重置所有精灵的旋转，将它们设置回0，我不知道为什么

 for (CCSprite *sprite in bounceBarriers)
    {
        curBarrier = sprite;
        curBarrier.rotation = 20;
        [self bounceCreator];
    }

//bounceCreator:

b2BodyDef barrierBodyDef;
barrierBodyDef.type = b2_staticBody;
barrierBodyDef.position.Set(curBarrier
                            .position.x/PTM_RATIO, curBarrier.position.y/PTM_RATIO);
barrierBodyDef.userData = curBarrier; //the userData is set to the current sprite

_body2 = _world->CreateBody(&barrierBodyDef);
barrierBodyDef.position.Set(0,0);

b2Body *barrierBody;
barrierBody = _world->CreateBody(&barrierBodyDef);

b2EdgeShape barrierEdge;
b2FixtureDef barrierShapeDef;
barrierShapeDef.shape = &barrierEdge;
barrierShapeDef.friction = 1.0f;
barrierShapeDef.restitution = 1.0f;
barrierEdge.Set(b2Vec2((curBarrier.position.x-70)/PTM_RATIO, (curBarrier.position.y+10)/PTM_RATIO),
                b2Vec2((curBarrier.position.x-70)/PTM_RATIO, (curBarrier.position.y-10)/PTM_RATIO));
barrierBody->CreateFixture(&barrierShapeDef);
barrierEdge.Set(b2Vec2((curBarrier.position.x-70)/PTM_RATIO, (curBarrier.position.y-10)/PTM_RATIO),
                b2Vec2((curBarrier.position.x+70)/PTM_RATIO, (curBarrier.position.y-10)/PTM_RATIO));
barrierBody->CreateFixture(&barrierShapeDef);
barrierEdge.Set(b2Vec2((curBarrier.position.x+70)/PTM_RATIO, (curBarrier.position.y-10)/PTM_RATIO),
                b2Vec2((curBarrier.position.x+70)/PTM_RATIO, (curBarrier.position.y+10)/PTM_RATIO));
barrierBody->CreateFixture(&barrierShapeDef);
barrierEdge.Set(b2Vec2((curBarrier.position.x+70)/PTM_RATIO, (curBarrier.position.y+10)/PTM_RATIO),
                b2Vec2((curBarrier.position.x-70)/PTM_RATIO, (curBarrier.position.y+10)/PTM_RATIO));
barrierBody->CreateFixture(&barrierShapeDef);

同时更新身体的旋转

   body->SetTransform([self toB2Meters: sprite.position], -1*CC_DEGREES_TO_RADIANS(20));

另外：路缘石。旋转=20；设置在那里进行测试。它被设置回0，而不是20。伟大的开始大师。这阻止了将旋转重置为0（我必须更改一些内容才能使您的方法正常工作，但是SetTransform（）方法是关键。但是，现在未设置bodyEdge，即未检测到碰撞。感谢您迄今为止的帮助，也许您还有最后一点智慧，因为这个问题在最后一天一直困扰着我。欢迎..快乐编码Sam。
