It bit of old news perhaps, but I’ll blame it on the season. 😉
For those of you who are following my Rubygame tutorial, once you’ve installed Rubygame 2.2.0, you may want to update your programs. You can get rid of the Surface#put_pixel method. You will also need to change the call to put_pixel to instead call set_at.
Hm.. Maybe I’ll just have to give an example in my next tutorial.
