Our production deployment setup for deploying Lucky on to Elastic Beanstalk in production.
We develop locally on MacOS. Due to some issues with cross compilation, we build the crystal binary on docker locally,
then zip that up and ship that along with the docker stuff to elasticbeanstalk.

Trying to get character movement similar to FinalFantasy V or VI. The character should move smoothly but always stop moving directly over a tile. Tiles are 64x64.
def initialize
@tile_x = 9
@tile_y = 7
@fine_x = 0
@fine_y = 0
end
def draw(renderer)
renderer.copy(sprite, dstrect: SDL::Rect[
@tile_x * 64 + @fine_x,
