Remember that Cocos2d-x uses the right-handed coordinate system, which means that the coordinate origin (0, 0) In the lower left corner of the display area.

auto dirs = Director::getInstance();
Size visibleSize = dirs->getVisibleSize();

auto myScene = Scene::create();< br />
auto label1 = Label::createWithTTF("My Game", "Marker Felt.ttf", 36);
label1->setPosition(Vec2(visibleSize.width / 2, visibleSize.height / 2));

myScene->addChild(label1);

auto sprite1 = Sprite::create("mysprite.png");
sprite1- >setPosition(Vec2(100, 100));

myScene->addChild(sprite1);

Scene switching

Director::getInstance()->pushScene(myScene);

popScene() releases the current scene, then pops the top scene from the scene stack and sets it to The current running scene. If the stack is empty, it ends directly.

Effect settings for scene switching

auto myScene = Scene::create();

// Transition Fade
Director::getInstance( )->replaceScene(TransitionFade::create(0.5, myScene, Color3B(0,255,255)));

// FlipX
Director::getInstance()->replaceScene(TransitionFlipX::create (2, myScene));

// Transition Slide In
Director::getInstance()->replaceScene(TransitionSlideInT::create(1, myScene) );
