Lua脚本有时不会将值保存在文件中 [英] Lua script sometimes doesn't save values in the file

问题描述

我为《我的世界》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、继续并重置时间。我的下一步是让它能够将时间保存在一个名为timesave.txt的文件中，但有时它不能节省时间，它只是空的……如果它节省了时间，它就会读取并使用它来恢复旧时间。 代码如下：

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'
 --
--[[

推荐答案

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

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