does anybody know if mementos procedural generation logic has a script or if it's hardcoded

[quaint lodge]

ive also been wanting this. i have a suspicion its all exe shenanigans from the bits of research ive done

(specifically the fare adjustment machines part)

[eager bobcat]

well even if it's exe as long as I can figure out where I should be able to temporarily modify it

[eager bobcat]

how much research have you done on it?

because I think DUNGEON.BF might contain some of the logic

[quaint lodge]

where is that

[eager bobcat]

but I haven't confirmed yet

it's in FIELD/ETC

[quaint lodge]

i imagine in the base cpk

(im still new to p5 modding so im not the most familiar with the game's structure)

[eager bobcat]

if it's a script it's usually in the language cpk

but yeah it's possible

[quaint lodge]

oh it is in en.cpk

[eager bobcat]

well yeah dungeon.bf is

I'm just not sure if it actually contains mementos logic or not

haven't read much into it

it's pretty long

[quaint lodge]

i do see mementos specific dialog in the msg data

[eager bobcat]

this seems suspect as well

like "Find parts" could mean the parts of the level that get stitched together for the procedural gen

[quaint lodge]

what do you use to properly decompile bf files by the way?

[eager bobcat]

Atlus Script Tools

there's also a GUI version made by shrine fox

[quaint lodge]

AT_DNG seems to also be relevant

[eager bobcat]

https://github.com/ShrineFox/AtlusScriptGUI

[eager bobcat]

I'll take a look

[eager bobcat]

most variables are obfuscated, but it can properly identify which functions are being used

since they're strings

programming 101: to make a scripting language work, you have to make the functions unobfuscated in your code usually

or at least it's easier to do it if you do

you can still use encryption with it, but there's usually not really a point

[eager bobcat]

this basically always just means it becomes a string that the exe can read

dll exports are actually similar

they also show up unobfuscated

[quaint lodge]

makes sense

[eager bobcat]

p5r doesn't use dlls though so examining the binary can be tough

there's community tools to help with that, but I'm a masochist so I'm doing it manually

most of the time

[quaint lodge]

i think its funny how it really is just one massive static binary

[eager bobcat]

gameplay functions are usually stored in the exe anyway

the bloated size is likely because of denuvo

[quaint lodge]

fuck denuvo

[eager bobcat]

lol

makes it take way longer to analyze too

Just Cause 3 took 30 minutes

P5R took 14 hours

[quaint lodge]

sounds about right

thank god theres a pre-analyzed ghidra thing

[eager bobcat]

but at least p5r has a lot of loose files

so you can modify a lot about the game

I don't mind going through the hard code though

I mean, I've been doing it a lot already

yeah

AT_DNG seems to have a lot of the mementos tutorial stuff

[eager bobcat]

also seems like denuvo completely destroys low level optimizations

[quaint lodge]

it sure does

in fact

universally

[eager bobcat]

higher level optimizations still work, so it's not always denuvo's fault a game runs poorly, but a game will usually run better without denuvo

[quaint lodge]

removing denuvo always will make performance better

whether major or minor, its still detectable

[eager bobcat]

like LOD optimizations being bad are not denuvo's fault

only CPU register optimizations are

[quaint lodge]

correct

also start times in general

[eager bobcat]

yeah

imagine Yandere Simulator with denuvo

[quaint lodge]

that actually probably wouldnt do too much

with the way unity works

[eager bobcat]

then it'd have poor high level and low level optimizations lol

[quaint lodge]

god actually

there is one way

[eager bobcat]

at the end of the day it all goes back to machine code, which is what denuvo actually hurts

[quaint lodge]

id imagine in theory you could "protect" the il2cpp binary

its also hilarious because denuvo pretty much always hurts sales more than the risk of piracy without it

game like p5r are the exception for me, as 99.9% of the time i just skip games that have it

(espescially since games that are hacked to remove denuvo run better without it anyways)

[eager bobcat]

well p5r has enough high level optimizations for denuvo's presence not to really matter

[quaint lodge]

anyways we're getting massively off topic

[eager bobcat]

like

the engine was designed for ps3

so damaging low level optimizations is balanced out by being played on better hardware

user experience isn't hurt that much

it mostly affects modders

[quaint lodge]

yeah

[eager bobcat]

either way

denuvo is an example of attacking the symptom and not the problem

piracy usually doesn't happen "just because", which is the attitude denuvo presumes

it happens due to lack of funds or accessibility

[quaint lodge]

its clearly not the solution since indie games lately outperforming AAA games by just being good games

[eager bobcat]

so just make your game accessible and don't charge too much, and don't do things consumers don't like, and you won't have to worry about it

in fact

expensive DLC doesn't really seem to contribute much at all to piracy

[eager bobcat]

that's always been the case

people buy games they want to buy

who'd have thunk

tbh I only pirate abandonware most of the time anyway

old games you can't get anymore

I've technically pirated 010 but I plan to buy it for real once I get the funds

it's a good tool

[quaint lodge]

yeah i did the same with fl studio

i had pirated it for years, and now im a proud all plugins pack owner

[eager bobcat]

nice

most software I use is free though

[quaint lodge]

black friday sale is INSANE

[eager bobcat]

I actually use Blender for video editing lol

[quaint lodge]

hundreds of dollars off

[eager bobcat]

unironically, it's my go to, and will probably remain as such since I'm familiar with it

[quaint lodge]

and the actual price of it without sale has been going down too

its just becoming more afforadble with better features lately

its awesome

[eager bobcat]

nice

[quaint lodge]

also thats interesting

didnt know that was possible

[eager bobcat]

hey @novel thistle do you have an answer to my question?

[eager bobcat]

Blender is a VFX tool

or it has VFX features

so it can do a lot of what after effects can do

[quaint lodge]

i barely know how to make a simple model in blender lmfao

[eager bobcat]

as a result of that: you can edit with it

well...

[quaint lodge]

the most complicated things ive done in blender is creating a path mesh for collision in a (incomplete) btd1 remake and following a tutorial for a sm64 romhack

that ive also not finished

[eager bobcat]

I actually think most of my time in blender has been spent on the video sequencer, not actually modeling or animating

but I have done models and animations

[quaint lodge]

i really need to learn how to do 3d model stuff, but motivation hard most of the time

[quaint lodge]

cute

[eager bobcat]

thanks

[novel thistle]

no i just followed to be nosy

[eager bobcat]

AT_DNG might be what I was looking for @quaint lodge

[quaint lodge]

huge

[eager bobcat]

it contains the wall breaking and chests

[eager bobcat]

this is a released mod if you want it btw, just to add some extra cute to the already cutest character in the game

also has a Sumi Overhaul version

[eager bobcat]

yeah I've got no idea

DUNGEON.BF and AT_DNG.BF are both related to dungeons

and have some mementos stuff in them

but I'm not seeing anything procedural

nothing about the ticket machine or whatever either

[quaint lodge]

if this helps at all, the fare adjustment machine's model is M091_201.GMD

if you can find what uses it

(im not the most sure how the game does stuff like this, but surely having the model name will help in some way)

[eager bobcat]

I can also check for GET_ITEM_WINDOW

since the script for that should be related

[quaint lodge]

i wonder how the game determines which pool of items to give you

like i know how logically its based on the section you're in

but i wonder if theres like a sort of switch statement type of thing somewhere

[eager bobcat]

this is the only thing between both files that has it

and it's not there

hrm

this might be exe

actually

it could be in a HIT file

[quaint lodge]

HIT?

[eager bobcat]

they tell the game what script index to run based on what trigger you hit

chests use them too

[quaint lodge]

oh interesting

[eager bobcat]

the problem is that mementos is procedural so idk what the name of the field files for it would be

HIT files are per field

[quaint lodge]

although the way mementos works with field items

they arent like chests

[eager bobcat]

yeah not sure

[quaint lodge]

yknow

the fare adjustment machine works quite similarly to the steal-able things in palaces

it even says "steal" when you go to interact with it

[novel thistle]

thats for will seeds i think?
iirc from poking around flowscript relevant to the seeds

[eager bobcat]

hmm

[eager bobcat]

so it could be a search object?

[quaint lodge]

it could be

[eager bobcat]

that could give me a lead

still need the right field file though

[quaint lodge]

it would certainly explain why its hard to pin down

[eager bobcat]

I know it gives you different SP restoring items based on what section of mementos you're in

[quaint lodge]

funnily enough

in theory it could be based on the song that's playing

[eager bobcat]

doubt it

song that's playing is also determined by the section

[quaint lodge]

since that conveniently lines up with the items it gives

[eager bobcat]

they'd just use both

[quaint lodge]

fair

but there could be shared logic

[eager bobcat]

I'm gonna look at the FBN files

those are basically the map logic files

[quaint lodge]

its still funny to me how overengineered this game is at times

all for a simple interaction

and then theres the phone images in conversations

[eager bobcat]

sometimes a "simple interaction" can be pretty complex

[quaint lodge]

that are just loose dds files

[eager bobcat]

void UseItem(const uint16_t charaID, Item& item)
{
    uintptr_t* joker = (uintptr_t*)(GetDatUnit(JOKER));
    uintptr_t* character = (uintptr_t*)(GetDatUnit(charaID));

    uint16_t characterHP = *(uint16_t*)(character + 0xC);
    uint16_t characterSP = *(uint16_t*)(character + 0x10);
    
    bool usedItem = false;

    if (item.quantity <= 0)
    {
        inventoryItems.erase(inventoryItems.begin() + displayItem);
        displaySelectionWindow = false;
    }

    if (item.teamRestore)
    {
        for (uint8_t i = 1; i <= 10; i++)
        {
            uintptr_t* unit = (uintptr_t*)(GetDatUnit(i));
            uint16_t unitHP = *(uint16_t*)(character + 0xC);
            uint16_t unitSP = *(uint16_t*)(character + 0x10);

            applyEffect(item.skillID, joker, unit);

            if (unitHP != *(uint16_t*)(unit + 0xC) || unitSP != *(uint16_t*)(unit + 0x10))
                usedItem = true;
        }

        if (usedItem)
        {
            item.quantity--;
            *reinterpret_cast<uint8_t*>(generalItemBaseAddress + item.type) -= 1;
        }

        return;
    }

    applyEffect(item.skillID, joker, character);

    if (characterHP != *(uint16_t*)(character + 0xC) || characterSP != *(uint16_t*)(character + 0x10))
        usedItem = true;

    if (usedItem)
    {
        item.quantity--;
        *reinterpret_cast<uint8_t*>(generalItemBaseAddress + item.type) -= 1;
    }
}```

my current code for using an item in my custom inventory

despite getting the function for using one I still had to do all this because of how reliant it was on the existing UI

I can pretty it up later

but for now that's how it works

[quaint lodge]

it doesnt look too bad to me

[eager bobcat]

it's just annoying I still had to make logic for reducing your item count

[quaint lodge]

lmfao

[eager bobcat]

like sure for my custom inventory elements

but for the game too

[quaint lodge]

also gotta say

*reinterpret_cast<uint8_t*> is quite hilarious to look at

[eager bobcat]

C++ style casting

[quaint lodge]

mixed with C style casting

[eager bobcat]

but you can just use C style casting still

[eager bobcat]

because I got tired of writing "reinterpret_cast" everywhere

[quaint lodge]

mood

personally

id just make a helper macro

[eager bobcat]

maybe

but C style casting works fine for this use case

[quaint lodge]

but then youd have to go and unset it to not conflict with other stuff

[eager bobcat]

I think it was primarily designed for reinterpret anyway

[quaint lodge]

yeah

[eager bobcat]

if I had to use dynamic or static casting it'd be different

but I really don't

anyway, I wonder if these are for mementos

[quaint lodge]

i wonder what the engine for p6 will look like

considering it wont be based on a ps3 game

(probably similar to metaphor's now that im saying it out loud)

[eager bobcat]

they updated GFD for metaphor

so it'll either be on GFD or on Unreal

@quaint lodge this was the right model, right?

[quaint lodge]

yes

[eager bobcat]

well this is not very helpful because there's no specific HIT file for mementos

[quaint lodge]

damn

[eager bobcat]

I'll look if there's a generic file for all of mementos

because there's no reason stuff like this can't be handled by a singular script

[quaint lodge]

this is atlus we're talking about here

[eager bobcat]

well I got busy with other things and coming back to it

D0 only exists for FBN files?

so it's likely that one script is in charge of mementos

if not just the exe itself

the p5 mementos models in field_tex are also labeled 09

just F09

instead of D09

since they're meant to be loaded dynamically I doubt they have MAP files

unlike other palaces

nevermind they do

they're just labeled 19

instead of 09

atlus moment

which means

the mementos HTB files are likely the 190s as well

well

HTB files don't seem to specify which procedure index to use for that

soooo

it might be exe?

mementos stuff is so confusing

[keen ridge]

AT_DNG is always Mementos whereas regular DNG is Palaces, so if it'd be anywhere, it'd be in something to do with the former. There are some pre-existing Mementos fields, but for the procedurally generated ones... almost certainly an exe thing, but I'd also check to see what logic is attached to the escalator within the Mementos entrance field.

[eager bobcat]

the escalator is in the BF

and the HTB

probably because it's always consistent

[keen ridge]

Makes sense.

[eager bobcat]

well I mean like

the HTB's script has the logic for exiting

but nothing for the SP restoring machine

but what's weird is that some mementos FBN files include the machine and some don't

so maybe the actual difference is just

which one gets loaded

I just wish I could find it

@keen ridge I'm gonna check the binary

is the flowscript command CALL_FIELD?

I'm gonna check the references to the function for that

[novel thistle]

is for loading regular fields but yee

[eager bobcat]

what should I check for mementos then?

[novel thistle]

shrug

[eager bobcat]

these don't seem right

[novel thistle]

atdng_quest_floor sems like itd be the one where you fight mementos requests

[eager bobcat]

and event floor feels like it's for deviations maybe

might just be a DNG command, not ATDNG

maybe this?

[eager bobcat]

did a little more investigating and I found this file

idk what it's for

but I'll just try changing everything to 100 and seeing what happens

does not look related

there's also FLDATDNGBONUS

gonna check that one

nope not that one either

[eager bobcat]

yeah I've got no clue what controls this

but I fixed the problem in my code

so
