If you have a custom movement system, you need something else, but for standard system, do this:
PHP Code:
replaceani( "idle", "newbody-idle" );
replaceani( "walk", "newbody-walk" );
replaceani( "grab", "newbody-grab" );
replaceani( "pull", "newbody-pull" );
and so on for all the different animations.
