I'm making a game and I have several cards that are created during the game. Each card needs some info, which is shared between cards of the same type.
So I have a class CardInfo, which holds a name among other things. Now I'm looking for the best way to get the existing CardInfo based on the name, or if none yet exists it is created at that time.
I currently tried two ways, which are quite the same.
First I had a CardInfoManager
, which held a list of all known CardInfo
, and when asked for one, it checked if it had one, and returned that or created a new one if none existed. I have this as a fully static class, and as a singleton with an Instance
method.
I also made an alternative, in which my CardInfoManager
(the static version) is basically inside my CardInfo
class. So CardInfo had a ByName
method, which then checked a static list in CardInfo
. This is nice because I can then make the cosntructor private, making sure the info is never created elsewhere.
So I was wondering, what is the best way of doing it? Is there a good pattern for this kind of functionality?
I'm working in c#.

To get an object by name, put your objects into a Dictionary.
There are a number of ways to add the CardInfo objects to the dictionary. Here's one:
