Importing .STCK animation - We need your help!

[shakotay2]

well, thank you, too. Seems it's similar with Perfect World's .stck files.
I did care for the "simple" ones only.

Maybe you can find a Saint Seiya .stck where at least the frame counts for all odd blocknumbers
(or all even numbers) are constant (and != 1)?

[CriticalError]

here a small tip of stck structure.

where is the news compared to this thread? viewtopic.php?f=16&t=11776&hilit=perfect+world+.stck

btw: one difference between the "none constant" .stck of Perfect World and Saint Seiya are these indices:

In run.stck from Natasha I've found a sequence which fulfills the needs I asked for above:

But it's a little bit too short.

I haven't found anything too big yet, but take a look at those animations from Mouses, specially his Repulse.stck.

17 seems to repeat twice, don't know how much that meatters:

great! Doesn't matter, I guess. That's a very good starting point, imho. Will try to adjust the script - but don't expect too much. And don't expect it too soon.

edit: well, forget everything what I said about frame interpolating and none constant frame counts.
True is: - the script simply reads the frames depending on the frame count, no matter whether counts vary
- 3dsmax seems to create (interpolate/copy?) missing frames automatically

Only problem is that we seem to have constant transitions because frames are just copied:

The anims appear and Floating hit 1 perform similar to Repulse. Not sure if that's what it should be.

[asdasd123]

here's the script which was tested with Repulse.stck for mouse only!

Thank you, thank you, thank you! This is such a great advance!
Yesterday was my birthday and I'm really, really happy just by seeing some movement

The anims appear and Floating hit 1 perform similar to Repulse. Not sure if that's what it should be.

Yup, I've tested with other animations (like walk and run) and either the model only moves with his head/arms, or I get "unable to convert. undefinded to type: float"
I'm uploading a new model with known animations and the model with the error

Also I've noticed something that maybe will help (or maybe you've already noticed).
Most (but not all) models seem to have a number of frames equal to twice the number of bones. Eg: 44 bones = 88 frames
Maybe every two frames should be rotation and transition of a certain bone, the trick would be knowing what bone is it (maybe the .STCK on the main folder is for that)

[shakotay2]

Maybe every two frames should be rotation and transition of a certain bone,

that's true for most animation formats (you did not look into the script, did you? )
btw: wouldn't call it "frames", it's animation data blocks. One frame in the transition data block, 17 frames in the rotation data block

the trick would be knowing what bone is it (maybe the .STCK on the main folder is for that)

the bone's list is logged in the Listener

or I get "unable to convert. undefinded to type: float"

that's animations with the index list I mentioned before (see picture in one of the previous posts)
Maybe it's sufficient to just skip them by inserting some dummy reads.
(nope, for _Walk.stck it's a little bit harder)

The indices are very likely to be the keyposes - so not a good idea to ignore them.

[asdasd123]

kkkkk did not. In fact ... i struggle reading code

Alright, what can I do to help ?

[shakotay2]

cross fingers?

Well, I'm stuck atm and this ate way too much of my lifetime today.

The rotations are no quaternions in Misty's _Walk.stck. So I ignored them as well as those indices.
As a consequence for so much ignorance Misty's just shrinking vertically instead of walking:

btw: wish you a Happy Birthday, subsequently! But no presents any more, I fear.
(Rotations will be the last thing I'll try ...)

Alright, they are crossed

Believe me, your efforts so far have been one of the best gifts I've recieved this year

Even if you can't figure it out, I'm really thankfull for your desire to help.

Really, thank you!

Hi XeNTaxX Member

and @shakotay2

i was asking for a animatin import script (3dsmax) (.stck) files...
i saw some threads on this forum about importing .stck files.

and i wil be very happy if someone have a working import script

[darksimonus]

it s possible to import animation stck in 3dsmax?
