My favorite code from this weekend

anim.go

// I couldn't have come up with this sober / well rested

const (
	FACING_LEFT    = 1 << iota
	FACING_RIGHT   = 1 << iota
	PLAYER_STOPPED = 1 << iota
	PLAYER_WALKING = 1 << iota
	PLAYER_JUMPING = 1 << iota
)
a := map[int]*Animation{
	PLAYER_STOPPED | FACING_LEFT:  Anim([]int{4, 5}, 400),
	PLAYER_STOPPED | FACING_RIGHT: Anim([]int{0, 1}, 400),
	PLAYER_WALKING | FACING_LEFT:  Anim([]int{3, 5}, 80),
	PLAYER_WALKING | FACING_RIGHT: Anim([]int{0, 2}, 80),
	PLAYER_JUMPING | FACING_LEFT:  Anim([]int{5}, 80),
	PLAYER_JUMPING | FACING_RIGHT: Anim([]int{0}, 80),
}
