Game.LambdaHack.Client.UI.PointUI

UI screen coordinates.

Documentation

data PointUI

UI screen coordinates, independent of whether square or monospace fonts are being placed on the screen (though square fonts are never placed on odd coordinates). These are not game map coordinates, becuse UI is larger and more fine-grained than just the game map.

data PointSquare

Coordinates of the big square fonts. These are not game map coordinates, because the latter are offset by mapStartY and represented by Point.

However, confusingly, Point is also used for square font glyph coordinates, though exclusively in context of rendered frames to be sent to a frontend, namely PointArray.Array, which is indexed by Point and is a vector, and so traditionally indexed starting from zero and not from minus one, as would be needed for consistency.
