There is a new (and still incomplete) version of eRadiRace posted.
Launch the new broken thing!
I’ve come to the conclusion that talking about learning Flash is about as interesting as watching The Paint Drying Channel. So, I’ll spare you further exposure to that curse. What I will do is post these things up as they are finished in the game design section, along with the source code and pertinent lessons learned. The code may be ugly, but it’s well commented.
The preview: Flash 8’s Draw API is your friend.
Lameness Alert:
Pre-production is in full swing on the next round of games at Helixe, which means I’m Johnny-on-the-Spot for the next couple of months.
So yes, expect further slippage on the Design-A-Day. You deserve better, and I’ll understand if you want to start seeing other designers. It’s not you…it’s me.
I’ll endeavor to keep you amused and entertained, if not enlightened, in the meantime.
Code to the new version after the jump.
