游戏场景：
....
auto edgeBody = PhysicsBody::createEdgeBox(winSize,PHYSICSBODY_MATERIAL_DEFAULT,3);
auto edgeNode = Node::create();
edgeNode->setPosition(winSize.width/2+origin.x , winSize.height/2+origin.y+10);
edgeNode->setPhysicsBody(edgeBody);
....
球：
auto dinosaurBody = PhysicsBody::createCircle(dinosaurSprite->getContentSize().width/2);
dinosaurSprite->setPhysicsBody(dinosaurBody);
当球与边缘身体发生碰撞时，它会弹起，我该如何移除它？
