Cheat Engine

[Nakor]

I have been searching the forums for this but somehow I have missed it. I'm sure it is mentioned somewhere but I can't find it.

So far in my scripts I have just been modifying what happens on an event in game (for example: player gains money -> player gains much more money). What I want to know is, how do I make it so that the player presses a button and a script is executed once (not toggled on but rather just executed).

To be clear:

Player wants to add experience.
Player presses hotkey.
Script is executed that adds 1000 XP to player character (0x3E8).
Player is free to trigger script again whenever they wish.

I'm sorry for asking as I really expect it has already been answered, but thank you for your help

easiest is just a cheat entry with an assigned hotkey that does that instead of an script
Rightclick the entry, assign a hotkey, and choose the option to increase value by, and fill in 1000

You just have to make sure that the address is valid (e.g. a aa script that gets the latest correct address and writes it somewher, and the cheat entry being a pointer type)

Alternatively, if you do code injection in an often executed part of code, look up the getasynckeystate method and execute an increase only when the key is down

Ok thank you. I don't know how to do those things yet but I will look into them.

Ok one more question here:

The code that executes when a player gains experience also does a compare (JAE) to see if the character should level up or not. I am now attempting to add 1000 XP when a button is pressed as you said but the check to see if a level up should happen is not being executed (the 1000 XP is added but the level up check does not happen). I handled this in my script to increase the amount of XP the char gains each time, but since this is a hotkey and not a script I don't see how to handle it.

What happens after you gain 1 point of experience in the game?
do you level up then ?

There isn't really an easy method to automatically level up on keypress, the code that checks if you should level up needs to be called at least once

The complex method is find code that is related to the increase experience code and executed every frame, and there call the function that increases experience if the hotkey is pressed, giving it the correct cpu/stack state before calling and restoring the state as well.
Not recommended and I don't think it's worth the time if you gain the level as soon as you gain some experience the normal way

[Nakor]

Yes if you gain XP in the game you level up then (as long as you are over the required amount).

I could just leave it and tell the player that they must gain XP normally to level up (which is easy to do in this game), but I would rather know how to do it correctly.

I suppose I could locate some code that executes a lot and do a compare and then JAE in there.

My largest problem right now is that I have never yet been able to track down pointers properly. I have tried many times but for some reason I just fail at that part of it. Most of the tutorials I have been searching through today seem very out of date with missing files and everything. I guess I will keep trying as it shouldn't be that hard once I figure it out.

Pointers in combination of code injection is easier
The code that gives you experience accesses that address. Just do a codeinjection there where you register a symbol and fill the address of that symbol with the address of the experience at that point
Then you can add [ symbolname]+0 as address which will point to your experience

I just put out a +4 trainer for the game. I ended up just telling them they have to gain XP normally in order to level up. I will work on improving it later.

I wanted to click the support cheat engine box but for some reason it doesn't seem to do anything. It just shows an extra blank window. Maybe it's because I'm in Canada or something? The window shows nothing, even if I put a address into the box. It doesn't show my site or your site or an advertisement or anything.

Support ce only works if internet explorer is installed. Also in development mode you'll see a different page

[Nakor]

I never uninstalled IE but I still see nothing in that window. I see nothing in both developer mode and release.
