Dragonfly Game Engine for CMM2

Author: Mark Claypool CMM2 port by Epsilon

Changelog

0.1: Initial version

Description

Dragonfly is a text-based game engine, primarily designed to teach about game engine development. The author wrote a free book that teaches how to program a game engine from scratch. For more info, see the Dragonfly website:

https://dragonfly.wpi.edu

This is a CMM2 MMBasic port of the Dragonfly Game Engine. Dragonfly as documented on the website and book, is a C++ Object Oriented Design. The CMM2 version, although written in MMBasic, has retained most of the Object Oriented Design, with compromises for the sake of performance.

Features:

• Sprite Animation
• Simple Kinematics
• World/View representation
• Timing support
• Bounding Box based collision detection
• Object Management
• Event Dispatching (E.g. collision, keyboard or nunchuk input events, user defined events...)
• Nunchuk support
• Sound support
• HUD support

Directory Layout:

• INC/ contains the game engine implementation
• TEST/ contain game engine test cases. They roughly match the assignments in the book but have evolved a bit more there to make sure that they can run against the finalized version of the game engine. The test code is messy but all test cases work and it's a good repository to check to see how certain parts of the API work.
• SaucerShooter/ A demo mini-game used to demonstrate most of the features of the game engine. SaucerShooter also serves as my benchmark for performance tuning: *ss_game: Starts the game *ss_game L: Starts the game and displays the game loop timing in the upper left corner. *ss_game F: Starts the game with frame rate limiting disabling and xProfiling enabled (ref. https://github.com/epsilon537/xprof_cmm2 for more info on xProf).
