Cheat Engine

[Antifringe]

Hello! My first contact with LUA scripting. I'm trying to make a value in my cheat table increment by some value (let's say +0.2) every second, and stop after reaching some maximum value (let's say 3).

I've found a few examples on these boards, and after some experimenting, I've found one that I can insert without generating errors:

When, where, and how is the function `ItemHack` called?

That function's first parameter, `Name1`, is never used

Your code isn't indented properly

Put `t.Enabled = true` on its own line (timers are enabled by default, no need for this in the first place)

Checking if `oldv1` is valid doesn't do much; instead, you should check if `mr` is valid

The local variable `v1` is never used

You set the new value of the memory record without reading the old value first. That's fine if nothing else writes to it; otherwise, that might be unintended

That comparison w/ the max value should be greater than or equal to, not just equal to. (due to floating point error, if you take 0 and add 0.2 to it 15 times, you get 3.0000000000000004440892, which is not equal to 3)

Thanks for the quick response!

I tried adding some more stuff to the end and now it works, but I don't really understand why :p

Thanks everyone, I appreciate the responses.

ArylinCE, I think this was code I lifted from one of your previous posts, so thank you for the head start!

I'm doing this now:

Thanks again! I needed to add an "end" to the last line, but then the script executed.

The problem is, it doesn't do anything :p. Doesn't generate LUA errors, but also doesn't actually change anything in game.

The current version of the code does not contain any deficiencies that require "end". Do not add.

Hey, thanks, I really appreciate this!

I updated Cheat Engine, and now things work perfectly. I suspect that the problem was simply just parts of my old (and bad) scripts that I hadn't properly purged, and the process of updating cleaned things up as a side effect.

I'm sorry to have wasted your time on a ghost hunt like that. this was all extremely helpful.

Hello again! Ive been playing around with scaling up the script to handle multiple variables, and it works great. Thanks so much to everyone that helped.

I'm trying to make things a bit more sophisticated now, and am running into trouble. Previously, I was telling the script to increment the value until it hits a cap, and then stop. I was inputting the cap value by hand, which works, but is clunky and requires constant editing as the game goes on. I'd rather dynamically read the in-game cap and use that instead. But I ger nil value errors for my new capacity variable when I try this.
