Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it:
-
Uses degrees.
-
Draws in quadrant 1 (0-90 degrees).
-
Right hand rule: 0 degrees is east, 90 is north, etc.
These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught it grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation.
-
REAL MATHS!
-
Simple drawing primitives.
-
PRETTY drawing primitives! Nearly everything is anti-aliased.
-
Plenty of helpers to make your code clean
See examples/*.rb
-
rsdl
-
ruby-sdl
-
libsdl & friends
See and/or run rubysdl_setup.sh. If you’re on OSX and have homebrew installed, running this will ensure you have a working setup.
You may want to run ‘brew update` beforehand to ensure you get up-to-date versions.
-
sudo gem install graphics
