Rome: Total War's Animation Modification

Glossary:

Stand = rest position of all animation, except for some animation set, all animation should start or end with position of this animation

Ready = position which character would take upon near the enemy position as ready for the fight

Advance = marching while ready, part of stand ready animation set

Retreat = Walking backward (not run away)

Shuffle = character combat manuveuring and movement without move their feet (especially when model get pushed by collision)

Selected = equivalent pose to ready on strat map character, it is pose which character do upon selected character by mouse click

null animation = not found it use in vanilla RTW/BI/ALEX or any mod so far but there is some hypothetical possibility for some possible usage based on cross comparison with M2TW animation mapping

Skeleton file's animation mapping

Tool requires:

1) IDX extract/packer, you could found it here.

2) RTW skeleton exporter (python3 script, required python 3 to work) you could found it here.

Skeleton files are inside data/animations/skeletons.dat. They need to be unpacked and convert to editable format (text) before edit and covert back to use in game.

There are 297 possible animation entries using in skeleton files, none of those files contain all of these entries and missing entries would under omission and represent by tail of "0" which represent skipping of animation entries.

 1) Character's idle position / standing crew idle position (rest position, whole table would called it shortly as "stand" as it is primary position which would coming back to visit often)

Note: 1) No vanilla skeletons that contain active entries for all of animation in mapping but all of them could be add/insert if you counting omission zeroes (zero tails) properly (modding skeleton by modder)

2) Vanilla RTW skeletons are very economical with animation entries inside so not all of those skeletons could perform all task you want to

 - Strat map animation's entries only available in skeleton specified for strat map character of specific type in vanilla
 - Character's ready idle animation entries are only using in skeletons from Rome:Medieval mods
 - Command signals animation entries are only available in swordsman, sword cavalry, and dagger skeletons in vanilla RTW
 - Artillery crew operation animation entries are only available in dagger skeleton in vanilla RTW
 - screeching animation entries are only available in dagger skeleton in vanilla RTW
 - Slingers and Head Hurlers using slinger skeletons which not able to shared with other normal units and only able to perform limit task due to they have additional bone (weapon bone) in their skeleton/model 

3) If animation entries missing in skeleton. these things could happened in game when engine demand such action to do on model

 3.1) If action is idle animations/taunt/celebrate varients, nothing would happened and character would stand in rest position instead
 3.2) If action is combat attack animation, it would never using varient entries that get ommision in skeleton and only using one that available for skeleton
 3.3) If death animation missing, game would crash before reaching main menu
 3.4) If command signal/chant/screeching animation missing, there would no sound that accompany those action and may not generate any effect in battle too
 3.5) Most of command-specific animation would generate ctd upon action if their animation entries get ommission/missing

4) Some animation entries still have no report on their role using by any sources, if anyone discover what they really are, please report

Modifying skeletons

In Rome: Total War, skeletons and animations are packed. You can find the vanilla entries inside the data/animations folder:

The savest way to modify animations and skeletons is to copy all the .dat and .idx files into a locally created folder. This folder should have the name 'animations', as otherwise the extracting tool won't work as supposed. You can ofcourse place this folder inside another one, such as the name of the mod you are working on.

When you pasted the files inside this animations folder, you can place the animations pack/unpack tools you can find here.
