修复Laya下图文混排不支持动画表情的问题

[CoderMzx]

无法Fork2.13的分支,只能在这里提了,3.0的修复方法理论一样

新建 ChatAni.ts 类

export class ChatAni extends Laya.HTMLImageElement {
    private _srcc: string;
    private frames: Array<fairygui.Frame> = [];
    constructor() {
        super();
        this.width = 72;
    }
    public set emoji(id: string) {
        this._srcc = id;
        this.frames = []
        let movie = fgui.UIPackage.createObjectFromURL(id).asMovieClip;
        let clip: fgui.MovieClip = movie.displayObject as fgui.MovieClip
        for (let i: number = 0; i < clip.frames.length; i++) {
            this.frames.push(clip.frames[i])
        }
        this.onloadHandler();
    }
    public get emoji() {
        return this._srcc;
    }
    private onloadHandler() {
        if (this.frames) {
            Laya.timer.loop(120, this, this.loopHandler);
            this.loopHandler();
        } else {
            Laya.timer.clear(this, this.loopHandler);
        }
    }
    private _count: number = 0;
    private loopHandler() {
        let frames = this.frames;
        let _count = this._count;
        let frame = frames[_count];
        this.width = frame.texture.width;
        this.height = frame.texture.height;
        this["_tex"] = frame.texture
        this.repaint()
        _count++;
        if (_count > frames.length - 1) {
            _count = 0;
        }
        this._count = _count;
    }
    public destroy() {
        super.destroy();
        Laya.timer.clear(this, this.loopHandler);
    }
    private isListener: boolean;
    public renderSelfToGraphic(graphic: Laya.Graphics, gX: number, gY: number, recList: any[]): void {
        let isListener = this.isListener;
        if (!isListener) {
            let _sp: Laya.Node = graphic["_sp"];
            if (_sp) {
                _sp.on(Laya.Event.DISPLAY, this, this.onDisplay);
                _sp.on(Laya.Event.UNDISPLAY, this, this.onUnDisplay);

                this.isListener = isListener = true;
            }
        }
        super.renderSelfToGraphic(graphic, gX, gY, recList);
    }
    private onDisplay(): void {
        this.onloadHandler();
    }
    private onUnDisplay(): void {
        Laya.timer.clear(this, this.loopHandler);
    }
}

在Main.ts的onConfigLoaded函数中添加
Laya.ClassUtils.regClass("femoji", ChatAni);

EmojiParser.ts 类中 onTag_Emoji 方法修改为

private onTag_Emoji(tagName: string, end: boolean, attr: string): string {
        return `<femoji emoji="${fgui.UIPackage.getItemURL("Chat", tagName.substring(1).toLowerCase())}"></femoji>`;
    }
