am not sure abt this.. but i think this is y u getting this:

maybe from an action function u cannot call another function. am not sure of this. if this is true, then the code in ur move() function, u can simply put it within ur action function itself.

and i think since u using the parameters arm01, arm02... etc.. these are from "my" entity and gets recognised within the action function but wont be recognised in the move() funtion unless u pass the parameters by reference to that function.

so i think best is u put all the code of move() function within the action function itself. it should be ok.
