I think this can be done already...such as in the Woodsmen faction right? Not sure it works with the AI though...
:| EDIT:... K, I looked at it. I think it is this...
- <skill>
<type value="move" />
<name value="charge_skill" />
<ep-cost value="0" />
<speed value="460" />
<anim-speed value="115" />
<animation path="models/marauder_charge.g3d" />
- <sound enabled="true" start-time="0">
<sound-file path="sounds/horseman_walk1.wav" />
<sound-file path="sounds/horseman_walk2.wav" />
<sound-file path="sounds/horseman_walk3.wav" />
</sound>
</sound>
</skill>
Or the one that is named "butt skill"... :| Not sure what that one is for, don't remember it...
<skill>
<type value="attack"/>
<name value="butt_skill"/>
<ep-cost value="100"/>
<speed value="90"/>
<anim-speed value="90"/>
<animation path="models/marauder_ram.g3d"/>
<sound enabled="true" start-time="0.2">
<sound-file path="sounds/horseman_attack1.wav"/>
...
</sound>
Anyways, not sure if this is GAE only...if it is, just use GAE for now...
