This was an experiment I worked on back when I was at Sony. While our team was working on the Playground space, one of my coworkers came across GML: Graffiti Markup Language. That seemed like an opportunity to me, so I implemented a minigame that would render a given GML file onto a screen within Home.
The implementation was fairly simple- just drew dots as found in the GML file, with lines to connect them. GML files also include time information, which makes it possible to have the result feel like it’s actually being drawn as the rate of drawing speeds up/slows down in response to the shapes being created.
I recently gave a workshop at the Academy of Art University on the CoronaSDK. After a brief overview of the Corona environment and the Lua scripting language, I led the attendees through the creation of a simple game.
The game demonstrates image loading, the use of display groups to offset rotation, simple physics, and dynamic text. It’s simple, but provides a decent introduction. If you’d like to download the files (images and source code), head here.
I’ve started playing with the Corona SDK just recently. It looks to be a great way to develop games for both iOS and android devices, and (as a bonus) relies on Lua. Finished a simple demo last night, where a player character responds to a screen touch by walking over to the point indicated, playing one of four different directional walk cycles.
The code isn’t the cleanest, but it’s enough to let me start to get a feel for the way Corona deals with sprite sheets. All of the art assets were lifted from Open Game Art- an awesome resource for game demos.
