8 Direction Movement For GB Studio

*CREATED FOR GB STUDIO 2 BETA 4-5*

GB Studio is a beautiful application for creating simple Gameboy games. It does a great job at giving a user friendly tool for anybody to easily create their own games that are playable on Gameboy hardware. I am working on a new full game for Gameboy using GB Studio, and have been writing my own code to add to the amazing tool.

8 direction movement is a feature in the works, but is lacking in the top down style stages (think The Legend of Zelda, Link’s Awakening style movement). I wrote a simple hack in a few hours that can easily be dropped into your projects.

Nothing in my project file is actually necessary to add this feature to your own projects, it simply serves as a testing ground for proof of concept. The one and only piece needed to add this functionality to your own games can be found in my engine eject at [ /assets/engine/src/states/TopDown.c ]. The modification can be found from lines 37-129. Paste this in your own engine eject at line 37. No other changes necessary. Can be dropped into any existing project to add the functionality of 8 direction movement.

Use at your own risk, though I can’t imagine any harm that can come from it. No credit necessary. Donations appreciated.
