How can i make my script works only one time?

[_insidious]

i wanna make that my script works only one time so at exit the script will be autodestroyed is it possible?

[XEKEX]

after you destroy the script the user can redownload it and executed again ...

[BadCase]

I am pretty sure this can be done by first renaming with os.rename and then removing the renamed file with os.remove

What's the point of "auto-destruction" of the file that is executed, if it can be simply backed up before executing it?

There are no ways (without using server) to prevent script from being executed more than one time that couldn't be easily bypassed, but if you still need to have that for some reason, basic approach is to check presence of certain file and only continue execution if the file is not present and to create that file right after the check has been passed.

You can save a file in the device if this file exists delete the script if it's not the execute it

You just need a good place to hide this file

no way, this is easy to bypass, someone can just use a file manager that that list recently created file, or just list everything by date, and got it

You can put this file in an root or in the system or in the game data for example

storing another file is the most useless thing to even suggest, i need the script will get autodestroyed after use

Save a file when the script executed for the first time and if this file exists make the script delete himself so even if he saved a backup it will delete himself when execute

That unnecessary, you can delete it right away on the execution, cause when you execute a script, it will be loaded in the memory, and the file source code is no longer needed until next execution

Not everyone has root privilege, and just like the /root, game data folder is no longer accessible without root on recent android version 10+

Okay your right do you have another solution

[MAARS]

Just put this on top of your script, the problem here will be that if the user is aware than you script self destruct, he can just make copies and execute the copies each time
 

local f_name  = gg.getFile():match("^.+/(.+)$")
local nf_name = math.random(10 ^ 9, 10 ^ 10 - 1) .. ".lua"

os.rename(f_name, nf_name)
os.remove(nf_name)

-- Your code start bellow here
gg.alert("I have deleted myself.")
