官方例子ShieldNode 如果改为在resources.load回调中addUserNode 节点不可见

• Creator 版本： 3.8.3

    initScene (prefab: Prefab) {
    resources.load("tilemap/shieldNode", Prefab, (err2, prefab2) => {
        if (!!err2) {
            error(err2);
        } else {
            error("nonono")
            const posArr = [v2(-249, 96), v2(-150, 76), v2(-60, 54), v2(-248, -144), v2(-89, -34)];
            const tmpP = new Vec3();
            for (let i = 0; i < posArr.length; i++) {
                const shieldNode = instantiate(prefab2);
                shieldNode.setPosition(posArr[i].x, posArr[i].y);
                this.tiledLayer!.addUserNode(shieldNode);
                this.shieldNodeMap.set(i,shieldNode);
                shieldNode.on(Node.EventType.TOUCH_MOVE, (event:EventTouch) => {
                    const deltaMove = event.getUIDelta();
                    shieldNode.getPosition(tmpP);
                    tmpP.x += deltaMove.x;
                    tmpP.y += deltaMove.y;
                    shieldNode.setPosition(tmpP);
                });
            }
        }
    });
  

  }

找到原因了 addUserNode的实现中 未调用markForUpdateRenderData 手工调用一下即可
也许这样实现是为了防止同一帧中反复addUserNode 导致反复markForUpdateRenderData ？

但看实现中是有判断dirtyVersion的：

public markDirtyRenderer (uiRenderer: UIRenderer | UIMeshRenderer): void {
    if (uiRenderer._dirtyVersion !== this._dirtyVersion && uiRenderer._internalId !== -1) {
        this._dirtyRenderers.push(uiRenderer);
        uiRenderer._dirtyVersion = this._dirtyVersion;
    }
}
