    Message comparison

    I am writing a message system for my game engine.
    I am writing a message director so object types can register messages as to ease the time the handlers are in actions.

    I do not want to run a for loop on a dword array to check if a certain unit type is to recieve this message for every message for every unit type.

    Is there a quicker way?

    Perhaps OR messages and some bit comparisons...
    This I do not know how to do.

    You should make a multimap (that would be a Dictionary abstract data type that can hold more than one value per key, implemented by std::multimap and the hash_multimap that comes as an extension with many compilers) that maps from the message ID to the unit types that are to receive the message.

    Re: Message comparison

    Sounds rather complex to write myself.
    I suppose I could use the STD for this

    I want to research std::multimap?
    I know what hash's are but I have no methods of generating them. You say the hash_multimap is a compiler extension? VC7 have it?



    Edit: Google provides crap for std::multimap tutorials, articles, etc.

    That helps once I get it working, but I don't even know where to start.
