最近项目中用到，求个代码样例，版本是cocos2d-x 2.2.2
您好请参考testcpp中的ArmatureScene.cpp示例。
// Define the dynamic body.
//Set up a 1m squared box in the physics world
b2BodyDef bodyDef;
bodyDef.type = b2_dynamicBody;
b2Body *body = 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.isSensor = true;
body->CreateFixture(&fixtureDef);
bullet->setB2Body(body);
bullet->setPTMRatio(PT_RATIO);
bullet->setPosition( ccp( -100, -100) );
body = world->CreateBody(&bodyDef);
armature2->setBody(body);
