[0]2.x的2Dshader在laya3.x已经无法使用了

private shaderValue: Laya.Value2D;

    static DissolveSurfaceSaveName: number = 9999;



    constructor() {

        super();

        this.init();

    }



    public init(): void {

        this.shaderValue = new Laya.Value2D(DissolveSurfaceSprite.DissolveSurfaceSaveName, DissolveSurfaceSprite.DissolveSurfaceSaveName);

//重要的一步  将渲染设置为自定义

        this.customRenderEnable = true;

        this.shaderValue.shader = new Laya.Shader2X(vs, ps, DissolveSurfaceSprite.DissolveSurfaceSaveName);

    }



    // 自定义渲染提交

    public customRender(context: Context, x: number, y: number) {

        if (this.texture) {

            context.drawTarget(this.texture as any, x, y, this.texture.width, this.texture.height, null, this.shaderValue);

        } else {

        }
