Quick list of abilities and their offsets in decompressed XComGame.upk

[PaxEmpyrean]

Switching abilities around takes some work. The Visual Perk Editor is helpful, but since it only tells you which values to replace rather than the offset of where those values are stored, it trips over itself when you have multiple instances of a skill in different trees or if you shuffle the skills around in the wrong order. To work around this, and because I'm rebuilding all of the soldier ability trees from scratch, I made a list of which value corresponds to which ability, and the offsets for each. Replacing abilities is as simple as overwriting the value at the listed offset with the value that corresponds to the ability you want instead. You don't need to start a new game for this to work with new soldiers, but existing soldiers get really weird if you mess with their ability trees.

Good work, thanks for that. ^^

Now that time has passed there are a few things that have changed on this topic:

 

1. The offset for different abilities have changed (updated values below).

2. Inspired by the Visual Perks Editor I and this thread I decided to create a tool of my own that handles offset.

 

The primary purpose was a user-friendly tool which makes it simple to visualize and create custom ability trees that can be installed with the ToolBoks mod.

 

Ironically on the very same day as the tool was created the Toolboks author anounced that he is including support for moding the abiltity trees directly in the ToolBoks mod...

But I guess it can still be used for reference or support when creating your very own distributable custom mods.

 

The tool is found here:

http://hem.bredband.net/bertrich/XCOM/PerkGen.htm

 

Current updated offset and default values are as follows:

This tool looks really great!

 

Would you mind if it was linked to from the wiki? Even better, is it possible for it to be embedded into the perks wiki page? The current perks page is here : http://wiki.tesnexus.com/index.php/XCOM:EU_Perks

 

Also, if I provided offset values, would you be interested in adding a 2nd option to create ToolBoks custom mod entries for my upcoming expanded perk tree?

[dubiousintent]

I'd like to suggest instead the table be placed in it's own page, and that linked from the Wiki "Perks" page linked by Amineri above. Then it can also be included in other categories (such as 'Category:Enum Values XCOM Modding') or linked by other articles or mods that need the information.

 

We now have a 'Tools' page. The tool can be linked from there. Please note there is section to describe what it does as well a place for the link in the References section.

I wouldn't mind at all. Would it be very impolite of me to ask if you could do it for me? I would probably spend the better part of a day figuring out how to do it and where to do it :)

I don't think it is possible to embed the tool directly in the wiki since it uses javascript.

 

Almost everything, including logic, in the tool is based on the principle that there is exactly 48 abilities and the code is very far from well structured and update friendly.

So I would probably have to rewrite more or less the entire tool to make the changes required... Challange accepted.

Just give me a few days to redesign how output is handled before I begin redesigning the entire thing :cool:

Same question to you... Would you mind helping me create the tool page? Or possibly give me a few hints how to do it?

I am completely new to the site and would be grateful for any assistance.

[dubiousintent]

I'll be happy to put an initial entry into the 'Tools' page, and then a dummy page from the template for the Table based upon what you posted here. I'll do that and send you a PM with direct links to both. Then you can edit either or both to suit yourself. And if you need a page to document your tool, we can put that up like we do for mods. Feel free to PM with any questions.

 

Don't worry about being new to the Wiki. It's been forgotten by many since it was first put up, but is getting more attention now. And it's only recently we have started to try to put some standard guildelines in place.

Not at all impolite, but probably unrealistic ^_^. I still have many many mods in the pipeline to completion!

The good news is that the revised GetPerkInTree functions are much more regularly structured. Each rank's hex code is exactly 22 bytes long, so offsets between the "byte-to-change" from one rank to the next follows that exactly. All the perks within a rank are in adjacent bytes.

 

For example, the support tree function header starts at hex location 0x6D6A76 in XcomGame.upk.

 

The function header takes 48 bytes, and there are two initial lines of code that take a total of 22 bytes. (both numbers here in decimal)

 

After that are 11 blocks of hex, each 22 bytes long. Each block corresponds to a rank (the code now allows up to 11 ranks, although only 1-7 will be supported in the initial release). Within each block, the perks are at offsets:

Perk 0 at offset 11

Perk 1 at offset 12

Perk 2 at offset 13

Perk 3 at offset 14 // perk 3 is defined, but will not be supported in the initial release

 

Each perk only occupies a single byte.

 

So basically to get the offset for perk 'x' at rank 'y', (assuming rank is from 1-11 and perk is from 0-3) you'd use:

 

Function_start + 48 + 22 + 22*(rank-1) + 11+(perk)

 

All four class GetPerkInTree functions follow exactly the same format. The only differences between the hex code are the initial offset, the header values, the table values for the two local variables, and the specific perks.

 

The lookup formula for each class would be identical to above -- the only difference is the Function_start value.

 

 

Psi: 0x6D63E8

Sniper: 0x6D6524

Heavy: 0x6D66EA

Assault: 0x6D68B0

Support: 0x6D6A76

 

 

The psi tree works the same as the class trees, but is limited to 4 ranks (it is a much smaller function)

[Bertilsson]

Hmm... Using functions to fetch information and make generally structured and well written code... What kind of strange magic is that? :blink:

I have been using more of a quick and dirty approach depending on a big array and a single function for everything.

So yes, as previously stated I will probably need to redesign the entire thing to be a bit more dynamic which would in turn probably be easier if I used some of that strange magic. :cool:

 

But, perhaps we can continue this discussion in a new thread related to the tool or your upcoming mod? I think we are getting pretty far from topic right now.
