Are there any Quake 3 maps in existence that accurately model large cities like Chicago or New York City? If so, where can I get such a map? If not, is it possible to use a SimCity 2000 or SimCity 3000 file for this purpose?

"Are there any Quake 3 maps in existence that accurately model large cities like Chicago or New York City?"

Probably not. BSPs aren't really made for outdoors.

"If not, is it possible to use a SimCity 2000 or SimCity 3000 file for this purpose? "

If you know what the file format is and don't mind displaying the city in 2d then sure.

Bleh ... are there any large, made-up city maps? Considering the time it would take me, an utter n00b, to create a city that big and detailed, I'd rather find one to download ... as for the SimCity thing, it was pretty much just an afterthought ... call it "wishful thinking".

Not that I know of. And BSP really isn't meant to handle large maps. On top of that, you can't use other peoples' maps for profit (without their explicit permission, which is unlikely) and have to ask them to use it even in a freeware release.

A very nice %it, indeed.

I'm definitely not making a for-profit game At this point, it's pretty much for my own benefit.

If a BSP isn't suited for an outdoor environment, what can I use? Would Cartography Shop (which I already have the full version of) suffice?

once again cshop is used to make bsps.

However, consider this aspect. If the streets were small and not like 4 lane highways in width you could make a bsp with an invisible roof just above the players head. this would simulate a dungeon maze yet fit the requirements of a bsp style map. For more open areas you would have to be carefull about breaking up the larger spaces with objects so the illusion of a larger open area was still available, allthough you could not get away with a football field in this regard.

If your just starting out, forget everything aboutwhat you want to acheive and just learn the basics. IF you embark on your master project without knowing the basics then your going to be rewriting the methods and so forth each time you discover some new improved data handling method that you should of known prior to this.

Save yourself a lot of grief and learn heaps about managing variables in many ways. Manipulating variables, saving them as files and reading them back in etc..

Anything is possible but work smarter not harder.

I'll have to get on that, then ... I'm going for a Grand Theft Auto-style game, in which the player can roam around in a large area. The player happens to have the ability to fly, and I can definitely see limiting the ceiling. However, I'd still like to attempt to make a city-like environment. From what you all are saying, the city can't be too big, but I don't want it to be too small either.

Try going with a matrix for the ground and some boxes for buildings. With decent textures you could make a pretty nice large city. Better than boxes would be to use some building .x objects and drop them onto your matrix instead. You could always make a nice city editor to allow you to place the buildings and shape the terrain etc. More work but better in the long run. I wouldn't try using bsp for big outdoor envoirnments.

Thanks, xtom I'll get right to that ... I'll probably use Matedit (I think that's what it's called) to get a good matrix, and then mess around with some building objects in 3DCanvas or something.

One idea you could use is have an elevation map. Similar to the way bryce or terragen makes terrain. The lighter the color the higher its elevation. You could take a map of NY and convert it with relatively little effort. As the layout would be set for you. The big part would be shading each building to its appropriate height. You could do that in bryce or a similar program (perhaps even in darkbasic if you understood it well enough to make you're own terrain generator) and export it, map it with a 3d texture program and import it into your game.
It's just an idea.

Hello. I have just completed a game with Streets and City Buildings. It's called Town Hall Toaster:

http://www.scotttown.com/games/index.html

I wanted to focus on two main buildings, so I spent a lot of time on the models for them. All other buildings were just background filler, so I used simple box objects for them with a bitmapped image.

Buildings and city scenes are kind of fun to make. My only advice is to make them very big. I scaled my buildings to 4000% in my game, and that worked pretty well.

hey, I made some code for loading elevation maps. If you want to see it, it's in the code base under the "matrix" section. Hope it helps.

TKF15H -- That is pretty sweet code. The only question I have left is, how do I enable collisions with the matrix? I can fly through it with the flying 300ZX I'm testing it with

use this command:
terr=get ground height(1,x,z)
if altitude < terr then (whatever you want to happen when it crashes)

CS3 can be used for this type of maths without any problems. you just have to use my X Exporter V2 to hide parts of the city you don't need (just hide limb). this way you should be able to use CS3 maps for your game.


Indi: CS3 even doesn't have map or bsp support, so where do you have this strange idea from?

America's Army uses BSP's for their large maps....I believe Morrowind does aswell...

Draez, nobody was really interviewing me. I made up the questions and answered them in a format that I thought would be easy and fun to read, and at the same time, informative.
