场景切换
阅读一下FairyGUI官方给的Cocos Creator 3.x 的 demo,可以看见它是怎么场景切换的。
- 场景里挂一个常驻节点
- 挂上一个脚本Entry.ts
import * as cc from 'cc';
const { ccclass, property } = cc._decorator;
import * as fgui from "fairygui-cc";
import Main from './Main';
@ccclass
export default class Entry extends cc.Component {
private _currentDemo: cc.Component = null!;
onLoad() {
fgui.GRoot.create();
this.node.on("scene_replace", this._onDemoStart, this);
this.addComponent(Main);
}
private _onDemoStart(demoStr: string) {
let demo: cc.Component = this.addComponent(demoStr)!;
this._currentDemo = demo;
}
start() {
}
}
这一行代码帮助我们先切换到第一个场景:
this.addComponent(Main);
- 在Main.ts的onload里加载fgui界面:
public onLoad() {
cc.assetManager.loadBundle("UI", (err, res) => {
fgui.UIPackage.loadPackage(res, "MainPkg", this._onUILoaded.bind(this));
});
}
private _onUILoaded() {
this._view = fgui.UIPackage.createObject("MainPkg", "Main").asCom;
this._view.makeFullScreen();
fgui.GRoot.inst.addChild(this._view);
this.StartBtn = this._view.getChild("StartBtn");
this._initBtnEvents();
}
其中MainPkg对应fgui中的包名,Main对应包内的组件名,这些代码观察demo即可。
- 在Main中切换场景
private _onStartGame() {
this.node.emit("scene_replace", "Game");
this.destroy();
}
这段代码帮我们从Main脚本切换到Game脚本
- Game.ts脚本的onLoad
public onLoad() {
let UIBundle = null;
cc.assetManager.loadBundle("UI", (err, res) => {
UIBundle = res;
fgui.UIPackage.loadPackage(UIBundle, "GamePkg", this._onUILoaded.bind(this));
});
}
private _onUILoaded(err, pkg) {
this._view = fgui.UIPackage.createObject("GamePkg", "Game").asCom;
this._view.makeFullScreen();
fgui.GRoot.inst.addChild(this._view);
this.BackBtn = this._view.getChild("BackBtn");
this.BackBtn.on(cc.Node.EventType.TOUCH_END, this._onClickBack, this);
}
- 从Game返回到Main
private _onClickBack(evt: Event): void {
fgui.GRoot.inst.removeChildren(0, -1, true);
this.node.emit("scene_replace", "Main");
this.destroy();
}
