How can I make a swing blade (the kind of blades there were in Arokh's lair) to move in my map. I've put a Swing Blade 02 object on the map and messed its properties a little but the blade's just laying on the ground not moving.
I've seen many timers and stuff in Ruined Village level and it seems that I must use this events mechanism but I have no idea how. Any help?

Was long ago when i used the editoring tool, but i think, those kind of objects where just "active" in singleplayer mode (like NPCs). Though i might think of some kind of workaround with animation and other stuff ...
