cocos2d-x
1

I’m looking for a way to get the current scene and set camera debug, but i get invalid access ;/

auto scene = HelloWorld::scene();
director->runWithScene(scene);

scene:

Scene* HelloWorld::scene()
{
auto scene = Scene::createWithPhysics();
scene->getPhysics3DWorld()->setGravity(Vec3(0,-10,0));
scene->getPhysicsWorld()->setAutoStep(false);
scene->getPhysics3DWorld()->stepSimulate(1 / 100);
scene->getPhysics3DWorld()->setDebugDrawEnable(true);

auto layer = HelloWorld::create();
layer->SetPhysics3DWOrld(scene->getPhysics3DWorld());
scene->addChild(layer);

return scene;

}

access:
Director::getInstance()->getRunningScene()->setPhysics3DDebugCamera(camera);

SOLVED

static cocos2d::Scene *scene; outside class
