Jemini Tutorial (Part 2 of 2)

In Part 2 of our tutorial, we’ll create some enemies for our player to fight. We’ll set up collision detection, use timers to make a pretty fading effect, and set up a custom manager to coordinate enemy movements and shooting.

Be sure to visit jemini.org for help on starting your own game!

A computer can mimic the style of a classical composer by analyzing sheet music. I bet GUIs could be (partially) generated for command-line tools. You just analyze how people mapped a CLI tool’s functions to a GUI wrapper (say, Git vs. GitX), then apply the rules you learn to other CLI tools.
