Scene Creation Workflow
A scene is an abstract collection of environmental factors in a game, a local unit for creating a game environment. Game developers represent a part of the game's world content by creating a scene in the editor.
Cocos Creator implements a free scene structure using a node tree and a node component system. The Node is responsible for managing the parent-child relationship of the node tree and the spatial matrix transformation Transform, so that all entity nodes can be easily managed and placed in the scene.
The component system gives nodes a variety of advanced features, such as MeshRenderer component, Animation component, Light component, Terrain component, and more. One of the necessary elements of the 3D scene is the Camera component, which represents the player's viewpoint in the game, without which nothing can be seen. Therefore, when creating a scene, Creator will create a node with the Camera component mounted by default.
