[Model Edit] [Request] .m2 file animation ID edit edit

[piloui]

Hi there.

Changing animation ID.

Why : When you swap your character for a crature, some animations are not available, so you need to edit the animation's ID of your .m2 file in order to trigger animations that were not available before.

Actually, 2 tools allows us to do that, but they are not up to date.
Glitchy's ME and CryectsTools.

If you load an old version of .m2 file with both of these programs, all is runnig well
Glitchy'sME :


CryectsTools:

Animation Sequences
0 animID: 0

 a - Change Animation
 q - Return to Main Menu

But if you load a recent .m2 file, everything goes wrong.
The structure of the last .m2 files has obviously changed.
Glitchy'sME gives an error message:


And CryectsTools gives us something that is more understandable :

Compare yourself.
Here is the <Animations> section of the .xml fileinfo from a .m2 file given by modelviewer :

It gives us more info of the strucutre of a .m2 file.
The animation's number ( 1 to 67 or more depending of the model you have )
The animation's ID ( Index found in the AnimationData.dbc of Wow )
The animation's length
The animation's speed
The animation's flag
etc...

And here is what CryectsTools M2Modder gives us for the same model :

Animation Sequences

1 animID: 5333

60 animID: 1102304625
61 animID: 1099545411
62 animID: 1105765179
63 animID: 4390911
64 animID: 1703937
65 animID: -1
66 animID: -1
67 animID: -65511

As you can see, these numbers do not look like ID numbers
For anim N°0 : ID = 5 > correct
For anim N°1 : ID = 5333 > incorrect
the .xml gives us ID = 0
5333 is not the ID but the length of the animation N°1
M2Modder seems to jump for 1 line every animation
For anim N°2 : ID = 0 > which in fact is the <moveSpeed>, 2 lines under the ID
For anim N°3 : ID = 32 > which in fact is the <flags>, 3 lines under the ID
Etc, etc...

Long post to come to the point of it, but it was necessary.
I have no solution for Glitchy'sME, just waiting for a new release.
CryectsTools is good enough to give us the sources of the command line tools in .cpp filles ( C++ )
I'm not good enough in C++ to update the tool.
But if some of you could do it, i would be very thankfull

Hi !
Thanks for your answer friend
I have already seen this pages, and last days, i burned my brain trying to understand your python scritp, but i couldn't ^^
The WoW.Dev Wiki's pages are full of informations, but if like me you are not good enough in programmation, you are still stuck to the same point.
I get your .py files and succes to have .pyc files, but i don't know what to do with.
If you have a link for a step by step/noob/friend tutorial, it would be great to put it here, please.
Thanks again.
