I took a look at your capx and you've made some unique choices for the way you have setup your game and there might be some ways to simplify what's going on.
For the sword swinging i'd recommend simply creating an animation of a sword swinging over a few frames in photoshop or whatever, then shape its collision box in the shape of a pie slice.
Have the pie piece always aim towards which way the mouse is pointing, and then use "on mouse clicked" play animation "swing" then
have a second event that looks to see if it hit a bad guy.
you can make it visible/invisible as needed.
