Anything you say in a game is automatically stored in memory, and is accessible via Cheat Engine memory scan. This means that if you've ran a script that you've worked on for a long time that you don't want anyone else to have, it's openly accessible to anyone who looks for it. There is no erasing it. There is, however, an ability to hide it: but not to hide it /from/ the memory - but to hide it IN the memory. If you spam the memory with incomplete, useless bits of the code, nobody will ever be able to find the full script - all they will find will be useless bits of it that can't be put together.

Any criticism/suggestions/alternatives to my idea? It's been a very important ongoing issue for as long as Script Builders have existed.

Well, that would probably be memory-inefficient, but would work to some extent, unless you reengineered the program to output chats to a file.

It can't detect anything as specific as an origin or an event, all it can access is memory.

I just came up with this idea about an hour ago. Yes, it is very inefficient for the script, but should be a very efficient solution to a very bad problem.
This is what I've come up with:

    local getSource = function(x) return x:findFirstChild("DSource") or x:findFirstChild("Source") or x:findFirstChild("source") end
    local scriptsource = getSource(script).Value
    local ssc = #scriptsource
    for i = 1, math.ceil(ssc/100)-1 do
        local newv = Instance.new("StringValue")
        newv.Value = scriptsource:sub(i*100, i*100+100))
        newv.Parent = workspace
        newv.Parent = nil
    end
    scriptsource = nil
    ssc = nil

You could simply scramble the memory and have the whole program run through a specialised memory allocator that moved memory around. However, this might be slow on systems with slower memory speeds.

Ohhh I'm thinking too complex. I see what you mean now.

What if you search for the part that spamms the memory then just scroll down?

gotta love the people who made cheat engine memory accessible
even though it can be used for the good
even even though it is named cheat engine, right, right?
awww:(

If you don't want people stealing your script, don't chat it in script builders!

Can't you do script:Destroy() collectgarbage("collect") then it's hidden from memory?

^ collectgarbage("collect") can't be run in normal scripts last time I tried it.

I tried bringing this to SH.

They vomited on it and then left, confused and worthless.

Wait, wait, wait

Cheat Engine is run locally. It can't access server-sided data.
So if I just ran collectgarbage("collect") periodically on everyone's client, would it erase all of that memory?

I don't know much about Cheat Engine, but it should.

Well I wish I had known that earlier. I've put too much time into developing fail systems at securing memory.

No. collectgarbage("collect") does not work locally.

Solution 1:

1) Create your own script builder using the script builder / the obvious source stored in that script builder OR just use loadstring() to generate it
2) Use a textlabel to send your data to the server.
3) ???
4) Profit!

Solution 2:

1) Program in studio
2) ???
3) Profit!
