    --[[ Floor triggers should call floorTriggeredEffect() on activate.
        Scripts and timers can call spinTo or spinTo2 directly.
        Scripts can include the chosen direction for spinTo or spinTo2.
        Timers and triggers default to a random direction.

       If you plan to call the effect from a floor_trigger through a script that
       calls either spinTo or SpinTo2, do so by calling your function with a delay,
       as shown in floorTriggerEffect(); or change delayedCall in floorTriggerEffect,
       to call your function name instead.

       And/or/also  delayedCall can send a facing direction as parameter to spinTo/spinTo2.
    --]]   

    function floorTriggeredEffect()    
       delayedCall(self.go.id, .35, "spinTo2")
    end

    function spinTo(self, facing)
       local facing = facing or math.random(4)%3
       local dir = iff(math.random() <.5, 1, -1)
       local loc = {}
       loc[1],loc[2],loc[3],loc[5] = party:getPosition()
       loc[4] = party.elevation

        spinTo2 is a cool alternate of the effect, but it might be unstable :(
       It crashed on me once, and I haven't been able to reproduce it.
       The error it gave, happened while checking for obstacles.
       (Afterwards) I had set it up on a timer to run it every .4 seconds while trying
       to wander the map in every direction and bump into things for a good five minutes.
       
       it's been edited since, and I've had no problems with it since,
       but it's something to be aware of.  If you use it and have any problem, you can
       always switch to spinTo instead; all you lose is the animated turn... which might be
       what you want anyway. spinTo's effect is instant.
