Title: I've run out of ideas...
Post by: The SaiNt on 2001-05-15 20:36:00
Ok, guys I really need your help here since I've run out of ideas. Below is rough idea of what I've analysed on the weapon data section in the memory of FF7PC. I have managed to map out almost everything in this section thanks to Terence's clue on the different types of attacks. My problem is here. In the chart below, under the column weapon selling status, i have problems finding out what each value means. So far, I only know the function of one of the values. This is what I need you guys to help me out with.

All values below are in decimal unless stated!

code:

         Wpn Attributes   Wpn / Atk Type   Wpn Attack Effect   Weapon Selling Status

Weapon Attributes (1st Byte)

3   Long Range
35   Normal

Weapon Attributes (3rd Byte)
----------------------------

160   Power up when suffering from status ailment
161   Power up when (Near death)
162   Raises Power when party members are dead
163   Damage Power Increased with difference of Yuffie's Lvl and Enemies Lvl
164   Damage is calculated based on difference of Max HP and Current HP
165   Damage is calculated based on difference of Max MP and Current MP
166   Damage is calculated based on amount of AP on equipped materia
167   Damage is calculated based on amount of enemies killed by character
168   Power of weapon increases if Tifa gets a MISS in her slot limit

Weapon Type(1st & 2nd byte)
---------------------------
1st byte 2   & 2nd byte 0 Weapon Type is Hand-Mounted
1st byte 4   & 2nd byte 0 Weapon Type is Hands
1st byte 8   & 2nd byte 0 Weapon Type is Staff
1st byte 16  & 2nd byte 0 Weapon Type is Headress

1st byte 0   & 2nd byte 1 Weapon Type is Spear
1st byte 1   & 2nd byte 2 Weapon Type is Sword

Attack Type(4th byte)
---------------------
4th byte 4  Attack Type is Slice
4th byte 8  Attack Type is Punch
4th byte 16 Attack Type is Cut
4th byte 32 Attack Type is Projectile

Weapon Attack Effect
--------------------
The numbers show what kind of hit animation will be shown when the weapon hits its target. For example, when Cloud uses the buster sword and attacks the enemy, a slice "explosion" is shown right? So the value for his buster weapon is 9 255 255. If you change this value to 42 255 255, the same value as Vincent's Quicksilver weapon, you'll find that when Cloud hits the enemy, a gunshot "explosion" will be displayed instead of a slice "explosion".

Weapon Selling Status
---------------------
244 255 is ???
246 255 is the default (???)
254 255 ???
255 255 means the weapon cannot be sold

Materia Slots
-------------
05 = unlinked slot
06 = right-linked slot
07 = left-linked slot

Buster Sword
------------
00DAFD18 = Wpn Attributes
00DAFD1C = Wpn Atk
00DAFD1E = Wpn Materia Growth
00DAFD20 = Wpn Attack %
00DAFD26 = Wpn Attack Type
00DAFD34 = Wpn Materia Slots
00DAFD3F = Wpn Atk Effect
00DAFD42 = Wpn Selling Status (I think)

Each Weapon is divided by 2C hex

**EDIT**
Argh, allignment is horrible! I need to sleep now, but i'm sure you guys get the general idea.

Title: I've run out of ideas...
Post by: Terence Fergusson on 2001-05-15 21:41:00
Two things I think you should be aware of.

First...
(1) All of Cloud's swords are Cut-elemental.
(2) Almost all of Tifa's gloves are Hit-elemental.
(3) Almost all of Cid's lances are Punch-elemental.
(4) All of Vincent's guns are Shoot-elemental.

Use the above to help classify the rest correctly.  (I'm not making these names up; if you finally locate the Battle Files, they'll be in there in glorious text format)


2nd thing.

No, no, NO!  Tifa's Ultimate Weapon does *not* increase due to missing limits!  And Yuffie's Ultimate Weapon does not power up according to differences between levels!

/me kills whoever started that rumour five different ways.


And have you noticed that the Yoshiyuki has the same effect number as the Princess Guard?  That just goes to prove what we've been saying all these years; the Princess Guard is not an Ultimate Weapon.


As for that last pile of codes... I'd guess it's more likely to be a Misc Status then just Weapon Selling.

Here's a test for you; change Tifa's Leather Gloves to 245 255, then see if you can sell it.


It seems that all the weapons have bits 4, 16, 32, 64 and 128 set.  Bit 1 possibly controls whether you can sell it or not.  Bit 2 is absent for Tifa's Leather Gloves, and Bit 8 is absent for every weapon except the three non-sellable weapons, every one of Tifa's gloves except her first, and every one of Red XIII's weapons, as far as I can see.


Oh, and you're still missing the Dex, Vit, Mag and Spr modifiers of each weapon.  (Not all weapons modify Spr and Vit though, and only one weapon modifies Dex)

(You're also missing selling price, but it's likely that that could be found in a separate area with *all* item codes; selling status might be there too...)

I'm currently looking into the weapon/armor/accessory data blocks and mapping their effects, so don't waste too much energy thinking about this until I unveil my results, saves us from doing a lot of work twice. So far I've mapped the accessories, except for a single 16-bit value, so you can pretty much ignore those for now. Every item (items/weapons/armors/accessories) has this value, it's what SaiNt calls selling status and should be interpreted as a 16-bit signed value (255 255 = -1, 254 255 = -2, 246 255 = -10). All the accessories have this value as -2.

The first two bytes of what SaiNt calls Wpn/Atk type is actually the equip mask. It is a 16-bit bitmask, and should be interpreted as:

code:

Bit     Equippable by
0x001   Cloud
0x002   Barret
0x004   Tifa
0x008   Aeris
0x010   Red XIII
0x020   Yuffie
0x040   Cait Sith
0x080   Vincent
0x100   Cid
0x200   Young Cloud
0x400   Sephiroth
[/quote]

So, the swords having the value 0x201 means that they're equippable by Cloud and Young Cloud. These equip masks are found in armors and accessories too, only in the accessories they are always 0x1FF (equippable by all normal characters).

I'll have more info to share later on.

Finally: SaiNt, it'll be a lot easier of you present your results in hex, since a lot of these stats are bitmasks/negative values.

Thank you so much for the effort  :)
BTW, Qhimm since you're working on the weapon, armour and accessories, I think I'll move on to either the items or the list of enemy stats.

I found it pretty stupid to classify things as shoot elemental since Yuffie doesn't actually shoot her shurikens? I believe projectile would be a better term?

As I said, I didn't make up those names.  Those are the names FF7 gives them.  Heck, there's even Shout elemental, which is given to very rare things like Air Buster's Energy Ball.  And the Cure spells fall under Restorative Magic (element) rather than Holy Power (element).

In fact, there's an awful lot of text used in the game that you never see.  But you knew that already... it's just surprising how much of it exists, even for battle mechanics.  (Example: Every attack in the game has a name.  Every single one.  Doesn't matter if the name doesn't show up; it has one.  Doesn't matter if you can't manipulate the enemy, or whatever....)

They probably just did that to clarify so maybe in beta testing it could be better tweaked...
