Hi Tyler - Isn't one of the points of C++ inheritance and polymorphism? In other words, maybe you could have a series of pointers (or, better yet, iterators - grin) to objects of type Square, which would be inherited as, say, Jail, Property (inherited in turn to Lot, Business, etc), Pay-day (or whatever it is in Monopoly). Then, you would just have pure virtual functions, such as one that could occur whenever someone landed on the square, passed over the square, or tried to leave the square, and then in the case of property you might have a Buy function, etc. I admit I'm quite new to C++, so these may be elementary examples, and this is only the wayI've been led to understand things. The thing I don't really know is how youwould know at runtime the nature of the square in question. For example,clearly on property squares you could execute a Buy function, but what wouldhappen if the user entered the command for 'Buy' on, say, a jail square? I should imagine you'd get a run-time error. Or maybe I'm giving C++ a bad turn: I guess you could just have all virtual functions in the base class, which, if they are impossible to execute, would just throw an exception.

But, my problem is this. If you have a car, or person, the object will be different, thus you can'tdefine the array to just hold a car, or etc. it has to contain all of those.Thanks, Tyler Littlefield.

How do you represent that on the computer?

Shouldn't you be able to just make a square and then point to theobject that is supposed to be on it or can you somehow just put an object onit? I thought OOP was supposed to be able to represent the real world. Thanks.

E.g, a vehicle will be a different object from a player, etc. Thanks, Tyler Littlefield.

Would that work? Thanks.

I'm thinking of writing a game in c++. I want to find a way to make the board and map. I thought about using an array, but then that would require that all objects are the same... Any ideas? Also, how are race tracks built? I want to do a bit of racing in the game, just not sure how to lay those out. Thanks, Tyler Littlefield.
