Interface ITextModePointerMapper
Maps a screen point to a position on a TextMode grid when the grid is not shown in its own place on screen, for example when a CRT effect curves and letterboxes it.
Namespace: Scylla.TextMode
Assembly: ScyllaTextMode.dll
Syntax
public interface ITextModePointerMapperRemarks
Install a mapper through PointerMapper. The view's ScreenPointToCell(Vector2, Camera, out CellPosition) then asks the mapper instead of using its own rectangle, so text selection, mouse reporting and hyperlink clicks follow the displayed image without any change on their side.
Whoever installs a mapper removes it again when it stops showing the grid.
Methods
TryMapScreenPoint(Vector2, Camera, out Vector2)
Maps a screen point to a normalized position on the grid.
