1. Versus Fighter for Nintendo DS
CS 470 Project
Ian Roskam

2. Project Overview Goals Why Create a versus fighter for the Nintendo DS
Make the engine reusable for future games
Focus on basic functionality
Why
I am interested in game development
Learn how to program on DS hardware
Build a code base for a larger game project

3. Game Overview Only one player single match Basic moves available
8 characters and 7 maps
Each character has unique attributes

4. Menu Hierarchy

5. Image Conversion Used GRIT to convert images
Puts raw pixel data in halfword linear array
Makes image loading faster
.section .rodata
.align 2
.global titleBitmap @ unsigned chars
titleBitmap:
.hword 0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD

6. Sprite Sheet 10x8 array of frames Characters have 80 frames each
Frames are arranged in animation strips
Strips are saved together on a single sheet image

7. Sprite Class Handles all image loading and animation of characters
Provides methods to load a particular animation strip
Pointer for each frame of animation

8. Delays Expected: Unexpected: Learning NDS 2D graphics hardware
Refreshing on C++ programming
Unexpected:
Processing sprites into usable sheets
Learning sprite manipulation

9. Conclusion Ambitious for a first project on new hardware I learned:
More about C++, particularly pointer manipulation
Poorly defined requirements make a project difficult to implement
