I'm currently working in another thread to find a better conversion method

here's my script:

I'm afraid this doesn't work correctly at the moment...

here's what I use to test the verts:

the commented code shows you all the verts (jumbled),
image:
while uncommenting it shows you about 10 verts (clean).
image:

export a vert selection from an mdl0 file with Brawlbox, and impoort that file...
(make sure to add about 2 lines of '00' to the end of the file in a hex editor before importing)

the attatchment below is not a pdf file
it's the vert export I used
import directly into blender
(zero's are already added)

Nice start, . The big issue behind your “jumbled vs clean” verts isn’t the math loop, it’s that MDL0 vertex streams carry their own format and scale. In Section 2 (Vertices), the header stores ComponentCount (XY vs. XYZ), Format (UInt8/Int8/UInt16/Int16/Float), Divisor, Stride, VertexCount, and DataOffset. For non-float data you must divide by 2^Divisor; hardcoding 1/256 will only be correct when Divisor==8. Also, use VertexCount instead of scanning until you hit a 0,0,0 sentinel. See the MDL0 spec notes for Section 2 fields and the Divisor rule. MDL0 file format.

Python tips that build on and ’s feedback:

  • In Blender 2.49 (compiled with Python 2.6.x), integer division of ints is truncating. Either import true division or divide by a float literal. PEP 238. Blender 2.49/Python 2.6 evidence.
  • Skip encode('hex'); unpack directly with struct and little-endian codes like '<h' (signed 16-bit). struct docs.

Minimal reader for one vertex stream (Python 2.6-friendly):

from __future__ import division
import struct as S

def read_vertices(f, vsec_off):
    f.seek(vsec_off)
    f.read(0x08)                    # skip len, MDL0 offset
    data_off = S.unpack('<i', f.read(4))[0]
    f.read(4)                       # name offset
    idx = S.unpack('<I', f.read(4))[0]
    comp = S.unpack('<I', f.read(4))[0]     # 0=XY, 1=XYZ
    fmt  = S.unpack('<I', f.read(4))[0]     # 0..4 per spec
    div, stride = S.unpack('<BB', f.read(2))
    count = S.unpack('<H', f.read(2))[0]

    code_size = {0:('<B',1), 1:('<b',1), 2:('<H',2), 3:('<h',2), 4:('<f',4)}[fmt]
    code, size = code_size
    scale = 1.0 if fmt == 4 else float(1 << div)

    f.seek(vsec_off + data_off)
    verts = []
    for _ in range(count):
        x = S.unpack(code, f.read(size))[0] / scale
        y = S.unpack(code, f.read(size))[0] / scale
        z = S.unpack(code, f.read(size))[0] / scale if comp == 1 else 0.0
        verts.append((x, y, z))
    return verts

Practical checks:

  • If your export only contains the vertices block, call read_vertices(f, 0).
  • Confirm byte order is little-endian and that offsets are file-relative for this section, as documented. MDL0 file format.

I have some comments on your code.

Also,

h = h * (1/256)

just zeros h.
Why do you want that?

Member Avatar for Tcll

the readvert function is not used yet...
it was an update to be used for later...

as for the h thing
try this:

def HexToDec(n):
	h = float(S.unpack("<h", S.pack("<H", int((n.encode('hex')), 16)))[0])
	while (h > 127): # uncomment this code for better results:
		h = h*(1/256)
 	return h

this takes vert offsets > 127 and multiplies them by (1/256)

sry my code is such a mess...
I'm not the best of programmers yet...

that was the code that works perfectly on Melee's dat files

I assume you are using python 2 because str.encode('hex') only works for 2.
in that case, 1/256 = 0 and 0*h makes h 0.

Member Avatar for Tcll

sry...
was editing my comment when you posted...
have you even tried blender?
I'll try your script in blender and see how that works...

okay, i'll assume that Blender uses Python 2.x but makes divisions convert to float.

You should probably do h /= 256 instead, which is the same but more concise.

Member Avatar for Tcll

You should probably do h /= 256 instead, which is the same but more concise.

blender 2.49b uses 2.6

and thanx :D
could never understand that until recently...

btw, your code works :D
but no differant from mine really :/

EDIT:
I deleted that readvert function, now realizing it won't work...

Edited by Tcll because: n/a

I'm just curious, what are you working on right now?

Member Avatar for Tcll

the title says it all :P

Member Avatar for Tcll

You should probably do h /= 256 instead, which is the same but more concise.

overlooked this last time...

you mean: h *= (1/256)

Member Avatar for TrustyTony

overlooked this last time...

you mean: h *= (1/256)

h = 0 would be more concise in Python 2. Or do you mean h /= 256.0 ?
Or are you making something, which should use divmod?

Edited by TrustyTony because: n/a
Member Avatar for Tcll

(1 / 256)*h = (0.00390625)*h

it doesn't convert correctly when I replace the (1/256) with float(0.00390625)
float(0.00390625) does nothing in the sence where (1/256) does

that being said...
IDK why float(0.00390625) doesn't work...

Edited by Tcll because: n/a
Member Avatar for Tcll

here:
these are the images I get with the differant methods:
note: h is not set as an int or float...

float(0.00390625)*h or (commenting out the entire loop):

(1/256)*h or float(1/256)*h:

Edited by Tcll because: n/a
Member Avatar for TrustyTony

If you have Python 2 you should get same result with 0 as with 1/256 and float(0)=0.0. I think you are not using

from __future__ import division

Maybe you should start to use that and use // when you need integer results.

Do

print 1/256*h

in code before assignment and

print h

after the assignment and see the results in console if you do not believe. 1/256 == 0 in Python 2 irrespective what type of h we have.

>>> h=123
>>> h=1/256*h
>>> h
0
>>> float(1/256)
0.0
>>> h=123
>>> h/=256.0
>>> h
0.48046875
>>>
Edited by TrustyTony because: n/a
Member Avatar for Tcll

-_-

blender 2.49b requires the use of Python 2.6 to run scripts
otherwise you can only use it's scripts

1/256 = 0.00390625 (!= 0)

every number counts

Edited by Tcll because: n/a
Member Avatar for Tcll

can someone please help me make progress??

I've got a bunch of impatient people on my end demending me to make progress...

enough with this nonsence...
int(1/256) = 0
(1/256) = 0.004 (using Wii to reply)

now let's just leave that alone KK
the h is the invalad vert offset getting multiplied by (1/256)

now I really need some help...
please.

SUCCESS :D

thanx jcao :D
got the verts for any file oto import

heres an image of the main file I was using:

Member Avatar for Member #929548

what do we do with the script?

Member Avatar for Tcll

what do we do with the script?

actually...

you've hit up on one of my old threads... :P

but to answer your Q, you put it in your blender scripts directory...
although it's only valid for 248a to 249b...
(25 and 26 use a different script system)

I do intend to pick up development on this again,
but right now, I'm a little overloaded... heh
