Revision 13060 changes the attack animation naming scheme in the actor files. This is done to allow for multiple attack animations (melee, slaughter, ranged, etc). Everyone making a mod (and creating/modifying the actors) will have to adjust to this change (see #1686 for a script to ease some of the changes). Example: <animation event="0.59" file="biped/rider_javelin_atk_a.psa" load="0" name="Melee" speed="50"/> becomes <animation event="0.59" file="biped/rider_javelin_atk_a.psa" load="0" name="attack_ranged" speed="50"/> where attack_ranged is one of attack_melee, attack_ranged, attack_charge (currently unused), attack_slaughter. The slaughter animations were previously using the (single) attack animation, which resulted in some visual awkwardness for ranged units. They should now be using a melee attack animation (using a sword/knife), but as there are a lot of units/actors I would like you to post here about related issues (missing slaughter animation, no attack animation played while it was played previously, etc).
