I keep running into an annoyance given that I generally enjoy games where you have inventories to manage. Usually you can bypass this using some "selected item count" but if you want an item you don't currently have you're screwed.

Generally you find a value, dissect the structure, find a pointer and from that you have pointers to every possible item once you test/identify them.

Thanks to the wonderful people here I had some Lua scripts that would add these pointers in mass so I would get to testing them but now I lost them to a HDD failure and have to remake them (surprise surprise, I have no idea how I made them work).

So my suggestion: expand on the "add address manually" button to be able to add multiple addresses with a defined interval between.

Quick mock-up and example:
http://puu.sh/t3Crg/a5a70ca436.png

This would add 200 pointers to the list, first would be [["game.dll"+0000xx]+320]+48, second would be [["game.dll"+0000xx]+320]+A8 (48+60), third [["game.dll"+0000xx]+320]+108, etc.

I ended up redoing something like that to populate the cheat table... Except a few hours later I found some CE functionality I didn't know about that reduced the work required massively and also will make the table much easier to fix in case something breaks... Learn something new every day I guess.

Could either of you help me please?

Affly, in coding communities it's somewhat a norm to post your own solution to your questions if you come up with them, so people like me can benefit too [8

Zanzer, I'm trying to dissect what you have posted along with the few results I get from google.

Here's what I'm working with. It's pretty much all there, minus the fact that I mostly have no idea how to manipulate the things I am trying to manipulate.

I'm trying to get this to work with address offsets. And I'm not even sure I'm handling everything the right way.

Zanzer · Posted: Mon Jan 02, 2017 9:13 am Post subject:

You still need to pass the address as "pcsx2-r3878.exe+003FDCA0"
Unless you have a "Player Attributes" record in your table with the address "pcsx2-r3878.exe"
Then you would've needed to pass the address starting with a plus "+003FDCA0"

I tried that and when I do AddCheatTableRecord("Test0", "pcsx2-r3878.exe+003FDCA0", 908, "string", 50) in gives me the below record, which has an offset of 38C. How am I supposed to set the offset for the record and how do I set the lengths for the record types that need them?

Zanzer · Posted: Mon Jan 02, 2017 10:27 am Post subject:

Oh, you set the offset as 908 (decimal).
You want the offset 0x908 (hexadecimal).

It correctly gave your string a length of 50.
Perhaps your string is unicode?

Thank you, that got me to figure out the offset error was because I wasn't adding "0x" to the _offset variable as I intended and I wasn't passing it in.

How do I set the length for an Array of Bytes record? It'd be nice to know how to do that for a binary type too if it applies, but it's not important because I don't think we've encountered any in our project yet.

EDIT: I still can't double post so..

Oh ha lol thank you both yeah I noticed that when you both did too xD It's not unicode, no. Not this particular string anyways, but I did test the unicode portion a second ago and it was working.

Someone else in this revival project I'm working on asked me if I could find them lua code to do this. I'd like to make sure it's "proper" before I pass it off to him, and to me that means working the binary values correctly as well as the AOB values. I think the rest are right though? I know AOB and String have sizes that need defined, and the rest are a set nber of bytes. Besides binary, I'm not sure how that value type works at all.

I did look in defines for the "vtByte" style code and I did check in Main.lua too. I ctrl+f'd for info in that and only found 1 thing. I could have searched poorly and not found something though.

Edit2: Okay thank you, that probably is all I need. I missed part of that last post. I'll post back in a sec with the new source for people. I did not see that listed in Main.lua so I probably failed at searching through it right.

You should add another parameter _parent and use that to determine where to append the new record.

Setting some properties of memory record is little tricky.

For example, Address, it is a string. Do not try assigning numerical types. You must use string. Example:
This code will set address to '400500'.

Thank you all for the replies!

I personally throw all my addresses into a class that handles all of the writeThing and readThing functions and more.

I'm implementing the _offset change, but can you explain these lines to me?
NewRecord.OffsetCount = #_offset
local index = 0
for i = #_offset, 1, -1 do

is "#_offset" a quick way to get the number of items in the list?

and "for i = #_offset, 1, -1 do"
we're creating and setting i equal to whatever #_offset is, and then looping while i is 1 through -1? I totally don't think that's right? lolol

Now I'm starting to lose touch. How exactly does setting multiple offsets work? Is it going to be like "[pcsx2-r3878.exe+0040239C]+760+ABC+123" or is it going to make multiple records, one for each offset? Like what is the end result going to be. I feel like this is way to call the code once and setup many addresses. But wouldn't it potentially be more beneficial to just loop a call to the function for every offset, since this looks like it would give every offset a generic name?

I was forming the function to be, 1 thing in, 1 thing out.

Can i just replace my if _offset ~= nil statement with yours?
I feel like I should edit it to check if the offset is a table or not, so if only one address is passed in they don't have to pre-parse a single offset into a table just to send it to a function.

I replaced the _parent part at the end with,

Yes, #_offset will return the number of items in that table.

for i = #_offset, 1, -1 do
Initialize i to equal the number of items in the table.
While i is greater than or equal to 1, do the loop.
Add -1 to i after each iteration.
If you're familiar with other programming languages:
for (int i = _offset.length; i >= 1; --i) {}

Lua tables start their index at 1, while the CE .Offset array starts at index 0.
The .Offset array is added from top-down visually in the memory record.
This means that index 0 is actually the last offset for the record.
So I flipped the insertion to make it more user friendly.

[pcsx2-r3878.exe+0040239C]+760+ABC+123
So the address above would be added as:

Cg on post 3000! lol

I am familiar with other languages, yes. I never did iterations that way until "recently" and "recently" i've only been using lua which i've been familiarizing myself with lol

Is that really a "do until i = 1" loop though? Or is it literally a "While i is greater than or equal to 1" loop?

Should my offset code be:

Same as a do until, yea. You can code your loops however you like. Smile

for, for each, while, do while, do until... they're all interchangeable
