Game wrapper library internally using cray (RayLib bindings to Crystal).

shards installFor now this is basically just an object-oriented wrapper around Cray/RayLib functionality.
Eventually will include more concepts such as a Viewport, basic Player or Player Controllers, UI messages, loading/saving, and other miscelleneous concepts to assist developing a game.
See the examples examples/hello_world.cr and examples/shapes.cr on how to use the provided classes.
Inherit your main game project class from Game to enable the RayLib setup and game loop.
require "game"
class FooGame < Game
def initialize
super(
name: "FooGame",
screen_width: 1024,
screen_height: 768
)
end
def update(frame_time)
end
def draw
end
end
FooGame.new.run
Game#run will initialize RayLib, and begin the game loop, calling Game#update and Game#draw which are meant to be overriden with your game and drawing logic. Use the built-in classes to draw with using #draw or call drawing methods directly with LibRay (available via the cray shard dependency).
def draw
# use built-in classes created in `initialize` or elsewhere to draw, such as `Rectangle`
@rectangle.draw
# or call LibRay draw methods directly
LibRay.draw_rectangle(x: 30, y: 30, width: 100, height: 25, color: Color::Red.to_struct)
end
Note: Since many features are currently WIP, interacting with LibRay directly is a valid option.
