Hi,
Made a custom trainer for myself and couple of other friends. But sending them updated trainer each time game gets updated is a pain.
I want my trainer to receive cheat table from a hosted location (a dropbox location would be awesome but anything would work). That's all. No authentication or anything.

NoOb Alert: An example trainer doing this task would be much much appreciated.

try get a socket/http dll compiled for ce lua.

or try this, if your windows installed powershell:

Why add this layer of unnecessary complexity? Just give them the Dropbox URL and done.

I don't think that insulting other people here is conducive to you getting help. Not only will it turn them away, but it'll turn people like me who read replies before posting away as well.

Have you written a trainer at all before in CE? Unless you're literally just updating static entries in the table in-place*, then it's going to need LUA form edits as well, in which case you'd probably just use a launcher program of sorts that launches your actual trainer.

And that brings into question how it would know when it's time to update. Are you going to stick a text file with a version check on the dropbox server (for the launcher to parse) or something, or just waste all your bandwidth having all of their copies needlessly redownload the current version every time they launch?

These questions are being asked because it seems like a simple thing, but it's not, and we want to make sure you're aware of what you're getting into. (Also I don't know if Dropbox would appreciate you doing this but that's your own risk.)



* - And if you are doing this manually each time the game updates, you could probably make AOB scans for code edits that will survive longer and save yourself some effort.

First of all, let me confess that I'm not familiar with lua scripting.

Secondly, I have generated a working trainer with ease using DaSpammer's awesome tool (thnx DaSpammer). But resulting exe trainer is ~4 MB.
Issue is: If I share a download link of trainer, it would require on each update:
1: Re-generating trainer exe.
2: Uploading it.
3: Would require them to download ~4Mb executable
4: Adding it again to antivirus exception.
Not that its impossible or anything, but its extra headache for them and for me.

Instead, I wanted to modify the trainer in a way that It just get the AOBs from a text file that is hosted online.

This way, I just have to update the couple lines of an online file using filezilla and everything is set up.
no need generating trainer again and again.
no need uploading and distributing link.
no need for them to download a new exe each time.
no need for them to add new exe into av exception.


You are right that dropbox wont work for this purpose. Instead I used an online website hosting's free service to host that text file.
Also version check is not important since we actively play the game and we'll know when game is updated and AOBs (hosted text file) needs to be updated
(hope i explained well)

Many thanks to panraven, who generously took time and shared a function that reads the file containing AOBs, from a given url from inside the trainer. This so far saved me and my friends tons of efforts.

p.s: Never meant to insult anyone, it just appeared to me a mean comment instead of constructive one, so i responded in same manner. If it was not a mean comment, my deep apologies to justa_dude.

if you don't own a website, I'd recommend using a url shortener and incase you change or move the file, so you could simply update the url destination.

And you're correct its better to update couple of lines using filezilla instead of downloading everytime the trainer.

Now second challenge for me (in order to make it more flexible) I want to populate whole hacktable dynamically

So, instead of this:

[daspamer]

Simply save in your server a table format data, like in this format:
global table like hacktable is, we'll just replace it.

Thnx very much, works like charm.

Code worked at first, then i changed urls to forum.cheatengine/robot.txt & forum.cheatengine/robots.txt and it started throwing error.

I'm trying to accomplish that:
if 1st url does not exist
or take more then 5 sec timeout
or does not contain a certain string in it,
cmdHttpGet should go look 2nd url.

If 2nd url too takes 5+ sec to load or does not have a certain string in it, show a network error.
Also bandwidth isn't a big concern because the hosted table is only a 2kb text file

I removed the question after posting because I wanted to give it hard try myself first and did not wanted to abuse the good help you guys are giving out.
Deeply appreciate the answer tho .

[panraven]

Sorry, not checked this thread.

Add back an 'assert' on opening file in 'readfile', this should make the cmdhttpget script handle common i/o error. But if the error occurs during debugging, it is likely caused by some typo or syntax error... eg. forum.cheatengine/robots.txt is not a proper url.
Add a 'wipefile' function in case the downloaded file need to manually clean up. (set file parameter to nil should not need this)

hi, I have been following this thread too. I created a trainer using lua with multilevel pointers. Using the 2nd post in this thread, I added one multilevel pointer of say ammo to a notepad file.

eg
"[[[game.exe+002F15D8]+19c]+14]+26"

I saved this exactly in ammo.txt

then in my trainer script i wrote

ammo = cmdHttpGet([[tiny-url/ammo.txt]])

now i used ammo where i need to read or writeInteger

It worked flawless

No I have 7 other multilevel pointers say for eg hp, weight, height, strenght etc etc

For each one of it have to create seperate txt files. Is there a way, I can upload all mutilevel pointers in just one notepad file?

like for eg
"[[[game.exe+002F15D8]+19c]+14]+26"
"[[[game.exe+002F15D8]+19c]+14]+36"
"[[[game.exe+002F15D8]+19c]+14]+46"
"[[[game.exe+002F15D8]+19c]+14]+56"

and save this data in text file called pointers.txt and upload it n website.
In the above txt 1st line is ammo pointer, 2nd line is hp pointer, 3rd line is strength pointer.

now i use this script in trainer
ammo = cmdHttpGet([[tiny-url/pointers.txt]])
hp = cmdHttpGet([[tiny-url/pointers.txt]])

how do I get lua to set ammo read from 1st line of pointers.txt
and hp to read from 2nd line and strenght to read from 3rd line of the pointers.txt?

Thanks

It will save me from uploading multiple text files for each pointer.
