Cocos2d-JS v3.0 alpha不支持cocos2d-x的Physics integration

cocos2d-x 3.0新的Physics integration，把chipmunk和Box2D封装到引擎内部

auto scene = Scene::createWithPhysics();
scene->getPhysicsWorld()->setDebugDrawMask(PhysicsWorld::DEBUGDRAW_ALL);

auto layer = HelloWorld::create();
layer->setPhyWorld(scene->getPhysicsWorld());

Cocos2d-JS v3.0

var scene = cc.Scene.createWithPhysics();
    //scene.getPhysicsWorld().setDebugMode(true);
    var layer1 = new GameBackgroundLayer();
    var layer2 = new MainLayer();
    scene.addChild(layer1);
    scene.addChild(layer2);

报错has no method 'createWithPhysics
