Cocos2d-x Lua node-and node-level architectureCocos2d-x Lua uses a hierarchical (tree) structure to manage nodes (node) objects such as scenes, layers, sprites, menus, text, maps, and particle systems. A scene contains multiple layers, and a layer contains objects such as sprites, menus, text, maps, and particle systems. Nodes in a hierarchy can be any object, su
