posted message: I'm back!
Hey everybody, sorry for no updates for so long. I've had deadlines for writing Test Pilot 1.2, the mobile phone version of Test Pilot, and I've also been training an intern.
But I'm back with new content: I just added example code for lesson 4.4 - it's a simple "platform game" which demonstrates how to find the contact points between a moving player and the edges of platforms and obstacles.
