Bots .bsc

Post by sfynx » Sat Mar 01, 2014 7:13 pm

Hey,

First of all I am kind off new to this. So forgive me for stupid mistakes.

I need some help with writing a noesis plugin. I saw some other thread about this here:
viewtopic.php?f=16&t=9092

Allthough I didn't want to bump that since it is kinda old.
Anyway I started writing a script with the information supplied by chrrox.
I have made a mistake somewhere I guess and that is the reason I can't read out the models like it should...
I only can't seem to find the mistake.
I wrote a standalone py script to decrypt the files and a noesis script.
They both don't work xD

fmt_bots_bsc.py -> is the noesis plugin
fmt_bots2_bsc.py -> is the standalone script
obj_ordener.py -> is used to be able to read the object files it supplies.
I supplied them in the attachments. Help is very much appreciated.

the standalone script doesn't draw or do anything. It only makes the file readable as obj.

Thanks in advance,

Mistakes are part of scripting.
I don't see any stupid mistakes (well, you shouldn't forget to close files.)
I need some help with writing a noesis plugin.
I always lose too much time trying it with Noesis
(though it's a cool tool once you know how to use it.)
I know Alsair made a complete Noesis Bout/bsc py script. So ypu may ask him for it since I didn't find it in his threads any more.
fmt_bots2_bsc.py -> is the standalone script
I changed this script so that it can read gr_010_arm.bsc

This is the result:

I don't have the time to fiddle out the startup thingie so I skipped all bytes before the counts:
os.read(fil,0x347) # The offset 0x347 does apply to gr_010_arm.bsc only!
important: the folder path for the bsc file has to be changed.
(I also changed the drive letter for the arm.obj to D: - so I was sure where to search for it).

thanks very much it functions now. I can read out heads.
didn't test other stuff but will manage it.
Wouldn't have figured out myself what to change with reading the faces :D:D

Well it has been some time. I finished the script to read out all meshes, unfortunately there is a problem left.
I now want to read out the bones and connect them properly and I found the file extension .cal kinda properly for now.
Pre's for me are that files are being put together in one file. Meaning I don't need to change very much about the way I am reading out now.
I just read out the meshes subdivide them in singled out files convert them with a third program and dump the names of the mesh files in the cal file.
And since the bones are saved in another file then within the model file. It seemed to be more logical to choose this.
If another extension would be better then this I'd like to know.

Now the major problem is I don't know to much about bones. How do they exactly connect to vertices and how is the information being saved(for .csf files, or your suggested extension)?

and for the bone files from bots. They seem to be saved weirdly. The same bonenames appear multiple times. Junk bytes are right after them which makes me suggest the start of the bone name skip is still intact with 0x42 bytes. Allthough what I came across with while checking it was 64 bytes long like here:

Code: Select all

Bone02.ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌBone01.ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ

Also sometimes one11 or something appears and I don't know if it shouldn't be read or if it is just a normal bone?
further I don't know.

I could definetly use some help with the layout for this.
Help of any kind is very much appreciated.

you can find a short dump of gr_bone.bon in my post as of Fri Jun 28, 2013 11:06 pm
in this thread: viewtopic.php?f=16&t=10549

Since Alsair seemed to have solved all problems I stopped further investigations.

(Imho bsc/bon files are not the very best examples to learn/understand rigging.)

Okay so not focusing on the .bon file from bots.
What I see from your dump is that bones excist out of 4 variables?
How does an extension like cal or something else know what the bones are connected to?

And what would you suggest to look at to know a bit more about rigging bones from seperate general bone files, before trying to work on the bon files?

Do you have the noesis scrypt that finale made?
I think some posts are lost/deleted at the link you provided last?

Not sure which vars you mean. The bones have a position and and 3 angles (rotations).

Not sure if I got what you mean. The game engine "knows" which data to be read from which kind of files.
Often the mesh, the weights and the skeleton are to be found in a model file and the animations in seperate files.
And what would you suggest to look at to know a bit more about rigging bones from seperate general bone files, before trying to work on the bon files?
Well, search for 'bones' in the forums. You'll get about 1413 matches. Then in the Search these results box type 'parent'.
You'll get 80 hits. Guess reading the threads these posts are contained in will help a little bit.
Do you have the noesis scrypt that finale made?
Which script are you talking of?
Or do you mean 'Alsair'?

Yes, I have his Noesis py script. But since he deleted it from the before mentioned thread I guess he didn't want it to be public any more.
So please ask Alsair himself for it.

Okay understandable. I will look into rigging and bone stuff now.
I sent alsair a message although he doesn't seem to be very active on these forums anymore nor on skype.
I will wait some longer, but have to ask you maybe in the future, to make the decision: if you could share it with me as I allready have the python scrypt without noesis...?
Owh and do you know some kind off layout for the general bone files on how to read them out?
Allthough I don't know to much about it, it would be nice to know at least how it is saved in there(if you at least know if not no problem).

Thanks anyway

Iirc the fbx file was exported from gr_trans_110.bsc

bon file should contain animation frames.
Seems like there are about 862 of them with constant values. So the object won't move. Strange...

Well from what I understand from the previous topic and from you is that the layout for the bone dat is kinda:

Code: Select all

search for bone name at the mesh piece
find bone name in bone file
skip from start of bone name 64 (or hex 0x40)
2 bytes damage hitbox data
2 bytes distance jump data
repeat(x3) 
for full bone data(x4):
3 floats bones location data
1 float as weight.
What I don't get is why do bone names excist multiple times and why do they give multiple times the same data?
Something I haven't found in the trans files is that bone names excist twice, because they have added x01 or x02. This is different in the general bone file where they do excist twice and data differences even at the repeats. which could be logical but every different mesh piece gets a different bone name. Meaning different bones. Unless the repeating data is the animation?

Sorry for not signing in sooner, anyways I indeed have solved almost all of this. However, the one thing I'm puzzled about is whether it can be automatically be mapped to some sort of skeleton. Since each frame has static position for each mesh piece, I wasn't completely sure.

When I Imported the fbx model into Cinema4D I noticed that there are no actual "bones" connecting each mesh piece, but rather they're all floating around with each position being different from each frame.

I'm not sure if I'm missing something in noesis to enable these bones, or if these models are not capable of this.

I have the animation and everything working just fine, but the meshes aren't connecting see here (after importing to Sunburn engine):

Iirc the fbx file was exported from gr_trans_110.bsc

bon file should contain animation frames.
Seems like there are about 862 of them with constant values. So the object won't move. Strange...
I also notice 4 bytes that aren't used for each bone - could it be possible it uses these four bytes to link to another bone?

All you've gotta do to define a skeletal hierarchy in Noesis is set the NoeBone's parent. Your format wouldn't actually need a hierarchy as the anim matrices are in model space rather than local space. But maybe they store it anyway.

I'm trying to figure out how it's stored, that way I can link them to form a proper skeleton.
