I am trying to create a game in Flash. There are 43 spaces of irregular shape in the game and I already know the X and Y location. I defined them as a class which extends movie clip, I put them on the main timeline to start and I gave them all an instance name. I want to initialize them when I am starting a new game. I defined methods to set and get the properties, those methods work when I use the instance name, but many of the spaces share the same properties. The instance names are all I+some numberm I1, I2, I3. When I try to use a variable name such as space\_Id = (“I” + i) to reference the instance name I get an error "Call to a possibly of undefined method. I tried the old actionscript 2 solution of putting an eval function eval (space\_id) in front of the method but that didn’t work either. It resulted in the same error plus a warning. I1.My\_Method (); // works but it would require 20 or so blocks of almost identical code var space\_Id:String = “I1”; space\_Id.My\_Method (); // doesn’t work \_root.space\_Id.My\_Method (); doesn’t work eval (space\_Id).My \_Method; doesn’t work Is there a way to use a variable to reference the instance name of an object that is a user defined class. Closest I got, I think is using the class name Space Space.eval (space\_Id).My\_Method (); generates Error #1123: Filter operator not supported on type class Space. Any help would be appreciated.
