Work in progress

So, I've made a few changes to our lovely game engine, and I've been working on my own game.

I'm not going to reveal all my secrets just yet, but I wanted to share some things I've been working.

I have created quite a decent a path following SpriteModifier. It takes an array of points, and your sprite will follow smoothly along it, rotating if necessary. I made this because it's the biggest part of the game I'm working on.

And, as proof of how easy the engine is. I went from no game, to where I am now (working on nicer graphics, bug testing) in just over a day.

Keep checking for my game release, and remember, get all the engine source code yourself free!

Shiny particles

First off, the code has only been online for a day and I've already had a couple of people get in touch with suggestions, so thanks!

Another hard days working on the engine, I've fixed a few bugs, added a number of SpriteModifier's. Most noticably, I have began work on the particle engine.

The code is available right now in the unstable build section, and is due to be improved significantly. But as a proof of concept, I've taken a little video to show what's going on.

Unfortunately, I only have a crappy camera, and while it looks jerky I can assure you the demo averaged around 45fps, and looked significantly better in the flesh.

Take a look, and let me know what you think!
