Lua 脚本有时不在文件中保存值

Question

我为 Minecraft 制作了一个计时器脚本，它应该显示在游戏中花费的时间。您可以暂停恢复并重置时间。我的下一步是让它能够在一个名为 timesave.txt 的文件中节省时间，但有时它并没有节省时间而且它只是空的......如果它节省了它读取的时间并用它来恢复过去。这是代码：

name = "Timer"
description = "Just a normal Timer."
positionX = 0
positionY = 0
sizeX = 24
sizeY = 10
scale = 1

START_STOP_KEY = 0x55 --or 'U'
RESET_KEY = 0x4A --or 'J'
 --
--[[
    Timer Module Script by SebyGHG original script by Onix64(Stopwatch)


    if you wish to change the key you can take the key code from here

感谢您的宝贵时间，希望对您有所帮助！ SebyGHG

在您的写入操作后添加io.flush()或timesave:flush()以将写入的数据保存到文件中。

见https://www.lua.org/manual/5.3/manual.html#pdf-file:flush
