Lambdas are also evaluated at runtime instead of compile time.Ī simple lambda: // create a simple Hello World lambda auto func = ()

Them! A lambda function is a function you write inline in your source code.

If you run the sample code for this chapter you will see a Menu containingĪbove we just learned that when you click a menu item it triggers a callback.Ĭ++11 offers lambda functions and therefore Cocos2d-x takes full advantage of * repeat for as many menu items as needed */ auto menu = Menu::createWithArray(MenuItems) creating a menu with a single item // create a menu item by specifying images auto closeItem = MenuItemImage::create( 'CloseNormal.png', 'CloseSelected.png',ĬC_CALLBACK_1(HelloWorld::menuCloseCallback, this)) Īuto menu = Menu::create(closeItem, NULL) Ī menu can also be created by using a vector of MenuItem objects: // creating a Menu from a Vector of itemsĪuto closeItem = MenuItemImage::create( 'CloseNormal.png', 'CloseSelected.png', Menu can have just a single item or many items. You tap/click the menu item and it runs the code you specified. On the menu item a callback is triggered. Have two possible states, a normal and a selected state. Cocos2d-x offers a variety of ways to create your menu items includingīy using a Label object or specifying an image to display. Menu object as a place holder for your menu items: auto myMenu = Menu::create() Īs we described options above of Play, Quit, Settings andĪbout, these are your menu items. Menus often contain buttons like Play, Quit, Settings andĪbout, but could also contain other Menu objects for a nested menu system.Ī Menu object is a special type of Node object. In your game you would probably use a Menu object to navigate through In your game you would probably use a Menu object to navigate through We are all probably familiar with what a menu is.We are all probably familiar with what a menu is.

CCNode::onEnterTransitionDidFinish () Reimplemented from CCNode.

If you override onEnterTransitionDidFinish, you shall call its parents one, e.g. If the CCNode enters the stage with a transition, this event is called when the transition finishes. You tap/click the menu item and it runs the code you specified. Event callback that is invoked when the CCNode enters in the stage. Well think back to that game loop example I gave earlier.

Now imagine somewhere deep inside Cocos2d-x when it performs the updateWorld portion, that it loops through all the the Nodes in the game and calls their update () method. If you run the sample code for this chapter you will see a Menu containingĪbove we just learned that when you click a menu item it triggers a callback.Ĭ++11 offers lambda functions and therefore Cocos2d-x takes full advantage of * repeat for as many menu items as needed */ auto menu = Menu::createWithArray(MenuItems) creating a menu with a single item // create a menu item by specifying images auto closeItem = MenuItemImage::create( 'CloseNormal.png', 'CloseSelected.png',ĬC_CALLBACK_1(HelloWorld::menuCloseCallback, this)) Īuto menu = Menu::create(closeItem, NULL) Ī menu can also be created by using a vector of MenuItem objects: // creating a Menu from a Vector of itemsĪuto closeItem = MenuItemImage::create( 'CloseNormal.png', 'CloseSelected.png', Well that’s basically exactly what happens. Lambdas are also evaluated at runtime instead of compile time.Ī simple lambda: // create a simple Hello World lambda auto func = () Them! A lambda function is a function you write inline in your source code. Using a lambda as a MenuItem callback: auto closeItem = MenuItemImage::create( 'CloseNormal.png', 'CloseSelected.
