Heroes of Might and Magic 6

[shakotay2]

Each curve seems to have 8 slots and inside of them we find the keydata:

Once I've understood what "slot" means I might continue.

I assume the keydata to be translations or rotations of the bones.

[shakotay2]

Since that nesting goes somewhat over my head I tried what I know better but still no clue which bones this belongs to.
(Simplest guess were: the data blocks (trans/rot) are ordered like the bones are in the smd file.)

Not sure whether it's for two different bones or two slots of the same bone. Probably the latter.
Weird format.

Got it. Each slot stores only a component of the translation/rotation/scaling curves:

Code: Select all

anim group 6 (Idle), frame cnt 80
        bone 10
                slot 0, slot id 5, keyCnt 1, max key time 0

Local transformation of bone 10:

Code: Select all

T:   -0.00297    -0.0233    -0.0973
R:   -0.555    -0.0588       0.82      0.127 -> 1
S:          1          1          1

Pretty much like the native format of FBX anim curves.
Conclusion:
slot 0 to 2: curves for tran x/y/z;
slot 3 to 6: curves for quat x/y/z/w;
slot 7: curve for united scale.

That doesn't mean that FBX anim curves use a similar nesting, do they?

No, just individual curves for x/y/z components.

Thanks.

I can find the rotation values for bone10, slot3 in your previous post but unsure about the translation values (slot 0 to 2).
Is it the bold blue rectangles? (sorry for the mess, didn't recognize the 4 zeroes, time 0 before the pos values):
.

I don't get it why there's 3 different positions for that bone at time 0. I assume the game switches the slots? But forward, back, left, right would require 4 trans slots?

(And why do I have the strong feeling that I'm wasting our time? With a game's animations, that I'll never play, haha.)

[Bigchillghost]

Seems like that.

There're 4 floats in every key, with the first being the time index, the 2nd being the actual component, and the remaining two are not used. So, the 2nd float in curve slot 0 to 2 stand for tranlation x, y and z correspondingly.

But forward, back, left, right would require 4 trans slots?

Forget about that. It was just a wrong guess.

And why do I have the strong feeling that I'm wasting our time?

Well, not if you're just curious about how it works.

[shakotay2]

Thanks for the clarifications.

So, the 2nd float in curve slot 0 to 2 stand for tranlation x, y and z correspondingly.

But wait, slot0: x, slot1: y, slot2: z? Are you sure?
Would make sense for me, now, but it's hard to believe. (Now I love those good old DirectX animation frames more than ever... Plain to understand and use. A little bit outdated, though. Admitted.)
