A collection of examples for common design patterns that I implemented in order to gain more practice using them. This is a very basic OpenFL project using Haxe and mostly some basic shapes for the pattern examples.
You can try it out here: https://tobbse.github.io/HaxeDesignPatternPractice/
However you will probably need to look at the examples to make sense of it. The UI is basic/stupid, just click the button in the top center to go to the next example.
