我有这段代码，我想在带有3个点的加载符号上循环，但我希望最后一个点闪烁以使其看起来像加载时一样，我不希望它是无限循环的，所以我需要帮助以使成功的循环在闪烁3次后结束。
@echo off
title Private Folder
color 0a
echo Welcome to The Private Folder
echo Made By Antonio Cardenas
ping localhost -n 3 >nul
ping localhost -n 3 >nul
ping localhost -n 3 >nul

echo Loading.
ping localhost -n 2 >nul

有人可以帮忙吗？
