My company is quoting a project that is, in essence, a first person 3D walkthrough of a maze. The user would be able to pick up items as he/she went along, and when time expired they would be lead out of the maze. Simple enough... however!!! Most of the data in the application (the maze and the items) would be dynamically generated (from a web-based database).

Other users could also log in and see what player1 was seeing, but not interfere or interact. I've already looked into Shockwave and created a sample interactive maze with Shockwave3D. It's the multi-player part that is scaring me away from Shockwave. Do I have a reason to be scared?? Is this something that Shockwave 3D should be able to handle, or is DarkBasic better suited? Time-frame for completion is probably 4-6 months. I'm a pretty experienced programmer (rexx, php, asp, javascript) and artist (Lightwave 3D, Flash, Director, Photoshop, etc..).

I'm really looking forward to reading your responses!

Thanks!

In theory you could write a server application using DBP that will take all incoming messages from the clients and update a database, probablby via PHP? (I know TCA has an sql plugin though: http://www.codingarea.co.uk)

If you don't want to have a server then there may be some way to use a web browser plugin to send data to a php script, updating a database and so on.

However if you want to make other users able to see what users are seeing, that'd be hard. The best way to do that would be to have a client application which gets info about the maze a user is viewing, then reconstruct it on their machine for the viewer to see.

Thanks for the link to the SQL plugin. Also this client wants a possible 100 people to be able to log-in and view the action. Can DarkBasic support that many concurrent users?

Once again, the users would not need any type of interaction, the would only see things through a following camera behind the main player. Again I stress.. I'm not sure if a lot of this is possible. I know Shockwave Multiuser server can support a maximum of 2000 connections, but obviously you are not getting the 3D quality of DarkBasic Pro.

DB can have up to 256 players in a multiplay game.

Can someone join a multiplayer game when it is already in progress? How hard is that to code? If someone can join in at any time, and be mapped to a camera that follows the player then I think DarkBasic should be able to handle this project.

I really appreciate your info!

Yes it can.

I have a very basic Chat example (written as an example a few months back) that I need to update. I can post the code when I'm done so that you can look at/appropriate it

DBP can do this, my first thoughts too where using the SQL plugin from TCA.

DB can support connections mid game. The player would act as the server, i'd most likely store the current server address' in the SQL database.

It would be best to use SQLite, as then you wont have to worry about whether the correct database system is installed, and whether the table is already present etc...

That's not usually a problem with a commercial project though
