question regarding actions

[dan12345]

hi i want to implement the following -
an avatar walks, and when she finishes walking i immediately manually
manipulate the bones.
(locking the bones, and then changing their angles - no motion)
how can i do this?

do i have to create an action ( i.e. a new class )
just for the simple few line code ( which won't need any update etc. properties ), or is there some other way to make things happen
once actions end?

thanks, dan
