1) Put a unit and name it like "civ" (not as a player) on the map and make a "move" waypoint. In the init of the waypoint type: civ switchMove "InBaseMove_repairVehicleKnl"; civ disableAI "ANim"; Now put a soldier as player and preview the mission. Shoot at the AI that plays the animation and he will fall to his death.
InBaseMove_repairVehicleKnl is a animation that is not under cutscene. It´s under unknown category.
2) Now again but now replace the "InBaseMove_repairVehicleKnl" with "acts_StandingSpeakingUnarmed" or any other animation under the cutscene category. Preview the mission and try to kill the AI. The animation will not end and the AI will not get killed.
And It´s only the animation under the cutscene category that don´t work. Under all other you can kill the ai while it doing a animation.
