Blue Rectangle - 2D platformer using Dunai and Bearriver

[AntanasKal]

Hello,

I have created a demo platformer Blue Rectangle using Dunai and Bearriver libraries and SDL2 bindings. The game implements continuous collision detection as outlined in the Functional Reactive Programming, Refactored paper.

In the paper a 1D bouncing ball example is given, but I was interested to see whether this technique can be applied to slightly more complicated examples (I was not able to find such examples yet). I also wanted to implement simple 2D platformer physics in a novel way. In the game some significant simplifications are still applied, such as: accelerations are constant (so the object trajectories are piecewise parabolas), no rotations are allowed, object shapes are rectangular. These greatly simplify physics and collision time prediction calculations. Also, I have not spent time optimizing the performance.

Hopefully that is interesting to you. Having warmed up with Dunai and Bearriver, I would be interested in contributing to the libraries :)

@AntanasKal would it be cool if I added this video to the announcement of the next version of dunai and bearriver?

Yes, feel free to add it :)
