Interpolation drifting: taking notes and removing link to script as it does't work (important: set no offset for frame 0 but all other, frame 8 and onwards)

===Issue=== | |||
[[Image:chr_debug_characters_shows_interpolated_animations.jpg|thumb|200px|right|5th line: current interpolation frame/total interpolation frames, TRAM name, current frame/total frames]] | |||
For unknown reasons some animations are unexpectedly interpolated. | |||
There is an XSI script that can do this: http://mods.oni2.net/node/358 | So far this has been observed with transitions from '''<u>i</u>dle <u>t</u>o <u>o</u>ther''' animations (any attack or movement). | ||
: chr_debug_characters = 1 | |||
: Use slowmotion cheat "carousel" or single step frame progression in developer mode for better visibility | |||
Normally, '''interpolations are encoded in TRAM''' files. | |||
:Example in XML, KONCOMidle1: | |||
<Interpolation> | |||
<End>0</End> | |||
<Max>65535</Max> | |||
</Interpolation> | |||
Despite the fact that idle interpolation is set to 0, ITO will always force an interpolation, most often it is '''8 frames''' long. | |||
Example in character debug display, KONCOMidle1 to KONCOMpunch_fw transition: | |||
0/8 KONCOMpunch_fw 0/37 | |||
When you let the character perform an animation via command line or scripting the transition will not happen which makes us think that ITO interpolations behavior is hardcoded. | |||
chr_animate 0 KONCOMpunch_fw | |||
KONCOMpunch_fw 0/37 | |||
===Proposed solution=== | |||
To compensate this phenomenon you can add a Z position offset to the pelvis either manually or by script. | |||
The offset would be applied to each keyframed Z position that is higher than 7 frames, create Z keyframe at frame 8 if necessary. | |||
By changing the later positions by the same amount only the delta value of frame 0 to frame 8 will increase - compensating z translation ITO shortens. | |||
===ToDo=== | |||
* create easy repeatable test setup | |||
* determine type of interpolation (is it linear?) | |||
** record and compare positions of each frame of OTI and programmatically played animation | |||
* write script to alter the Z keyframes (8 to last) | |||
* finetune the script if necessary by taking into account interpolation type | |||
