Swarm.Game.World.Coords

Description

World coordinates.

Synopsis

newtype Coords = Coords {
- unCoords :: (Int32, Int32)
}
locToCoords :: Location -> Coords
coordsToLoc :: Coords -> Location
type BoundsRectangle = (Coords, Coords)

Documentation

newtype Coords Source #

World coordinates use (row,column) format, with the row increasing as we move down the screen. We use this format for indexing worlds internally, since it plays nicely with things like drawing the screen, and reading maps from configuration files. The locToCoords and coordsToLoc functions convert back and forth between this type and Location, which is used when presenting coordinates externally to the player.
