2DPlatformer [Demo]

2DPlatformer is a short demonstration of various platformer movement mechanics. This game began as a side project during the development of X-BOW. I started this project partly as a break from X-BOW, and partly to test out the state pattern and my ability to reproduce platformer mechanics.

The state pattern is a solution to the issue of increasing complexity surrounding an objects state. A state is the current condition of an object and decides the behavior of the object. When an object has numerous states each with different conditions it can quickly turn into a spaghetti of if/else logic. The state pattern suggests that each state should be moved into its own class. The benefits of this approach include: when the state code is separated it is clearer to read and understand; additionally, each state's code is self-contained and changes made to one state won't affect another.
