 Posted: Tue Mar 19, 2024 11:31 pm Post subject: How Can I Store Values VIA AA Script? |
 |
|
I'm looking to scan last projectile fired on Halo 2, and then store its' value in an allocated storage.
I don't want duplicates of the same projectile IDs filling up all the ID slots, and I don't want the occupied ID slots to get overwritten with more recently fired projectile IDs.
The code I wrote works for several minutes before crashing the game randomly. There's got to be a better way to do this.
The purpose for this is every Halo .map has different values for all projectiles, and it would be asinine to play through every map to build a dropdown list. Please help!
Warning! Redundant Code Ahead!
| Code: | { Game : mcc-win64-shipping.exe
Version: 1.0
Date : 2024-03-02

Scans the last fired projectile and storges all the different type of projectile
IDs. They are unique on every map.

wtf why did you unroll that loop like that
You don't need 0x48 bytes to store a 4 byte value
I guess `converter` is the "Output ID" memrec in Cheat_Functionality.jpg
Do you really need `swapMode`? You could just do both. Recording a new value and modifying the value in memory isn't mutually exclusive.
Why are you pushing and popping all those registers all the time? You should only need to push / pop each register once- push it at the beginning (back it up), use it as many times as you need, then pop it at the end (restore it)
I didn't really read those 1000+ lines of code in that unrolled loop. You should probably just edit your post and delete everything between `store_3:` and `store_20:`. Readers can figure out the rest
A bit better:
| Code: | ...
aobscanmodule(projectileRead,halo2.dll,45 33 C9 44 8B 80 90 00 00 00)
alloc(newmem,2048,projectileRead)
alloc(scan,8,projectileRead)
alloc(swapMode,4,projectileRead)
alloc(converter,4,projectileRead)
alloc(projectileStorage,80,projectileRead) // 4*20
label(checkStorage)
label(loop)
label(exitLoop)
label(recordValue)
label(originalCode)
scan:
dq 0
swapMode:
dd 0
converter:
dd 0
projectileStorage:
dd 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 // 20 4-byte values
newmem:
mov [scan],rax
cmp dword ptr[swapMode],0
je checkStorage
// try to swap: check value
mov r8d,[converter]
test r8d,r8d
je originalCode
// swap game value w/ user-defined value
mov [rax+90],r8d
jmp return
checkStorage:
// loop through projectileStorage, record game value if not yet recorded
push rcx
push rdx
// rbx is free right now
mov r8d,[rax+90] // r8d = game value
lea rbx,[projectileStorage]
xor ecx,ecx
loop:
mov edx,[rbx+rcx*4] // value in projectileStorage
test edx,edx
jz recordValue // if projectileStorage slot is 0 (no record), use this slot
cmp r8d,edx
je exitLoop // if value is already recorded, ignore it
inc ecx
cmp ecx,#20
jb loop // only check at most 20 items
exitLoop:
pop rdx
pop rcx
jmp return
recordValue:
mov [rbx+rcx*4],r8d
jmp exitLoop
originalCode:
mov r8d,[rax+90]
jmp return
projectileRead+3:
jmp newmem
nop 2
return:
registersymbol(projectileRead)
registersymbol(scan)
registersymbol(swapMode)
registersymbol(converter)
registersymbol(projectileStorage)
... |
Memory record addresses should be `projectileStorage`, `projectileStorage+4`, `projectileStorage+8`, `projectileStorage+C`, ..., `projectileStorage+4C`

I went ahead and made the post much shorter like you suggested. Thanks for your help! I'm going over your example code now.
Your code is genius! Only thing is, the script is not storing the projectiles for some reason. When I fire all the addresses in [rbx+rcx*4] change to 00000000.
Issue_1: 1st Fired Weapon Results In All Storage IDs Equaling 00000000
Issue_2: 2nd Fired Weapon Results In All Storage ID's Equaling ??
Sorry to ask, but please help further if possible!
Please view attactments for clarity on current issue.

What does the "Change address" window of the memory records "Storage_ID_*" look like? They shouldn't be pointers; they should just be simple addresses. Like in your first post, "Cheat_Functionality.jpg"

I'll change them to see what I get. Thanks!
Edit: All is well! It was a blunder on my part using pointers. You're a mad genius Penguin thanks!
I will do test runs for each map. To clear the storage list I must deactivate and reactivate the script or set them all to zero when the map changes.
If players try to use IDs from the wrong map the game will crash. Any incorrect ID converted to output will crash the game.
