Cheat Engine

Little Cheat engine knowledge.

Ok, basically, i am trying to make the hud of far cry 3 dissapear and reappear on key-press. So there is a video on editing the FC3.dll file here:
youtube . com/watch?v=d5ftlActORg

However this is permanent,. What i want is on button press so i can get it back.

This mod (trainer) that does so. Google: Greetings to Malmo by tomsolo, 1st link. (Cant post links yet)

However this trainer only works on the old version of FC (FC v1.04). I am trying to get it to work on the latest versiuon (FC V1.05). I have tested it with 1.04 and works.

So the modder kindly attacted the CT file, and i open it to try and convert it to V1.05. Here are the Auto Assembly Script for this function:

[ENABLE]
FC3.dll+2A4608:
push FC3.dll+1504374

[DISABLE]
FC3.dll+2A4608:
push FC3.dll+1504390

So basically, i used a hex editor and found this address 2A4608 in the FC3.dll but the values we not the 1 below it, (1504374). So my question is why, and is what i am doing even correct?. If not how do i make a script that does the hex editing of FC3.dll form the youtube video into a keypress action. such that i can activate or deactivate the hud.

That location is a static point in the game code for the old version of the game.
You need to open the version where that code worked and find the AOB.
Use those AOB to scan for the correct location in the current game version.

Edit: Just watched the video, this should work:

Thanks Alot it works perfectly!

Edit:
So i've grown an interest and was wondering if i could dig into this (if that's ok) So there are other tweak\functions this trainer has, which are not included in the video. Say if i wanted them to work with the latest version, how would i do it?

A simple example (In this case, its interaction prompts, which is also gets disable when hud is disable):

[ENABLE]
FC3.dll+40316B:
db 90 90 90

[DISABLE]
FC3.dll+40316B:
db 89 46 20

You said to find the AOB of the static point, so the static point would be FC3.dll+40316B right? But when i run the older version (V1.04) and search 40316B as hex (4Bytes) i get nothing? But if i search all value types i get too many addresses to get the AOB, and have no new hex numbers to scan again with to reduce the number of addresses.

Am i suppose to search that? It is 4 bytes and hex right? Basically what is FC3.dll+40316B? Because when i open the old (V1.04) FC3.dll and go to the line 40316B, i don't get either hex value 89 46 20 or 90 90 90. It is some other values that form symbols.

"FC3.dll+40316B" is static FOR THAT PARTICULAR VERSION. But probably not for other versions. What you want to search for is an AOB, which is basically what you have in your "Disable" version next to "db", except it''ll probably be longer than that. So you'd want something like
