c# - Best inheritance / interface structure for storing many game constants? -


i have game data structured this:

public class craftablefiretower {     public static list<resourcenumber> requiredresources = new list<resourcenumber>     {         new resourcenumber(resourcetype.wood, 100),         new resourcenumber(resourcetype.stone, 50)     }; }  public class craftablefrosttower {     public static list<resourcenumber> requiredresources = new list<resourcenumber>     {         new resourcenumber(resourcetype.wood, 120),         new resourcenumber(resourcetype.stone, 70)     }; }

which combination of interfaces, abstract classes, inheritance, static methods / classes can use make them generic can pass them methods without creating new instances of classes every time?

    if (inventory.hasresourcesfor(craftablefiretower))     {         inventory.removeresourcesfor(craftablefiretower);         serverworld.buildfiretower(position));     }

i tried interface, can't have static methods on interface. tried abstract class can't make static abstract class or static abstract method. i'm trying impossible? there better way structure hard-coded grouped numbers/constants game data?

i think factory class queried find cost of returns instances of things if requested.

metainfo firemeta = new metainfo(100, 50);  factory.registercraftable(craftablefiretower, firemeta);

with 

factory.getrequirements<craftablefiretower>();

and

factory.new<craftablefiretower>();

internally factory uses dictionary store meta information each craftable instance such resources , build time.

the idea others have mentioned separate information class class itself
