Versus Fighter for Nintendo DS CS 470 Project Ian Roskam

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

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

Menu Hierarchy

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 @ 65536 unsigned chars titleBitmap: .hword 0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD,0xADAD

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

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

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

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
