NDS 3D World Toolset
After having a bash at creating a 2D game for the NDS (Finger Monkey and Inverto Goose) I decided to have a try at a 3D game.
I had a look at "NDS World Studio" which is a very good program, but as I like to program games in C++ and use OOP it didn’t meet my needs.
I decided to create my own model exporter. The exporter features:
- Exports each model as a c++ class for easy implementation into a game
- Supports multiple textures
- Bounding Box data for collisions
After getting this initial exporter running and creating a 3D game engine to load them I found it was a pain to place objects to create a good looking 3D world.
I developed the exporter further into a Map Creation tool, which features:
- Load in X-Files
- Displays models in both free and top down views
- Create large worlds quickly and easily
- Setup collision costs and object types
- AABB data generated
- All code needed to create a 3d world is exported, just a bit of copy and pasting into the NDS 3d engine.
- creates bat files for use with Delfares texture exporter, which works really well
The features of the 3D engine are:
- 3D Models created as C++ Classes for easy OOP implementation
- 3D object instancing – less NDS memory used
- AABB (axis aligned bounding box) collisions
- Collision costs – different cost result in different actions
- Simple Car Physics
- Follow and Overhead camera
Anyway after creating this toolset and 3D engine I started work on my game,
But recently I got a job programming computer games so no longer have the time to continue this.
I hadn't initially planned to release any of this apart from the final game, but then decided that someone else might find it useful,
So below you will find a user guide, game source code and 3D engine source code. Read the User Guide for information on how to setup, run and use.
