nod. I can do that. Also, I was thinking of using vectors of pointers, because there might be say two people at one place. So, the vector could just hold that. Will be a bit more memory consuming, but I think it should work. Thanks, Tyler Littlefield.

In C++ you can declare it as follows: Object *city[10][100][100]; where "Object" is a virtual base class from which you can derive Cars, Bus, Pedestrian and operations such as turn and move. Make these operations or methods abstract virtual functions in your base class. This assumes your city can be represented as a finite set of points and discrete movements of objects. This is probably the simplest, albeit the most restrictive implementation, but it could get you focused on how the game might work. Just a thought. Happy hacking. --le ----- Original Message ----- From: Littlefield, Tyler To: programmingblind@xxxxxxxxxxxxx Sent: Friday, October 12, 2007 10:14 PM Subject: Re: game development layout question Inthane, I want to make it like city streets.

E. quarter mile, Indy, NASCAR, formula 1, 2, 3, 4, 5, grand prix, flat track oval/sprint car, figure 8 dirt track, demolition derby; so on and so forth, if you know of a game that is similar to what you want to build, that can give me an idea of what you want as well. or just the name of a race you have seen that caught your interest, like the "long beach grand prix" that's held out here every year, or the "Indianapolis 500" laters, inthane .

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.
