Classes and subclasses typecasting in unityscript

Hi !

Code first, so i don't get lost into useless specifications:

 class mydevice
 {
 var integrity:float=100;
 var deviceName:String;
 }
 
 class battery extends mydevice
 {
 var storage_power:float
 }
 
 class generator extends mydevice
 {
 var recharge_rate:float=25;
 }

Now, since my goal is to add mixed types of device subclasses (batteries and generators) into a list, in order to compute, for example, the sum of storage_power or recharge_rate

And I succeded doing that, creating a list of type "mydevice". But this way, i can only see in the inspector, the variables belonging to the "mydevice" class, but not the subclass variables (and that definitively makes sense).

My unelegant solution was to put an enum "tagging" the mydevice, and checking for it's original subclass

     for(var i=0;i<ship_devices.Count;i++)
     {
     if ((ship_devices[i].type == ShipDeviceType.Battery))
         {
             var typecast = ship_devices[i] as battery;                
             print("this is a battery, with storage = "+typecast.storage);
         }
     }

I'd like to know if there is a better method than this, which by the way surprisingly works in retrieving the subclass variables. Basically what i'm looking for, is being able to add different derived subclasses to a single list, without "flatting" them to the class they extend, without having to tag them or put enums just to mark a difference between them.

Thank you and have a good day !
