文件夾規范

Constants.ts 用于控制全局
GameScene:游戲入口文件
gameManager是控制全局的變量,講入口文件賦值給它,這樣其他組件引用Hello的時候,可以使用GameScene里的屬性.
GameState是一個enum類型,其中每個值都是上一個值+1,用于控制游戲狀態.
gameState表示當前游戲的狀態.

import GameScene from "../../scripts/GameScene";export enum GameState {READY = 1,PLAYING,PAUSE,OVER,
}class Constants {private static _instance: Constants = null;constructor() {return Constants._instance;}public static get Instance(): Constants {return this._instance || new Constants()}public gameManager: GameScene = null;public gameState: GameState = GameState.READY;
}
let hello = Constants.Instance
export { hello as Constants }

在Player.ts里使用入口文件的函數:

const {ccclass, property} = cc._decorator;
import { Hello } from "./hello";@ccclass
export default class Player extends cc.Component {onLoad(){Hello.gameManager.setNewCoin()}
}
