如何从cocos2d世界获得b2BodyDef ...？

我使用box2d创建不同形状的项目..我使用下面的代码创建了一个正方形.`b2DedeDef bodyDef; bodyDef.type = b2_dynamicBody;如何从cocos2d世界获得b2BodyDef ...？

bodyDef.position.Set(screenSize.width/2/PTM_RATIO,50/PTM_RATIO); 
    bodyDef.userData = sprite; 
    _sqrBody = world->CreateBody(&bodyDef); 

    // Define another box shape for our dynamic body. 
    b2PolygonShape dynamicBox; 
    dynamicBox.SetAsBox(.5f, .5f);//These are mid points for our 1m box 

    // Define the dynamic body fixture. 
    b2FixtureDef fixtureDef; 
    fixtureDef.shape = &dynamicBox; 
    fixtureDef.density = 10.0f; 
    fixtureDef.friction = 0.4f; 
    fixtureDef.restitution = 0.1f; 
    _sqrFixture = _sqrBody->CreateFixture(&fixtureDef);`

我想搬到这个object.How我可以在 “cctouches” 提前.Thanks move..any代码..

body->setTransform(myposition, body->getAngle());

你可以给myposition

自定义位置
