Expand description

Assorted tools and UI states that’re useful for applications built to display maps.

Modules§

CameraState: Represents the state of a widgetry Canvas.
CityPicker: Lets the player switch maps.
ColorDiscrete
ColorNetwork
DefaultMap: Track the last map used, to resume next session.
DrawRoadLabels: Labels roads when unzoomed. Label size and frequency depends on the zoom level.
DrawSimpleRoadLabels: Draws labels in map-space that roughly fit on the roads. Don’t change behavior during zooming; labels are only meant to be legible when zoomed in.
EditPolygon
FilePicker
FileSaver
Grid: A 2D grid containing some arbitrary data.
HeatmapOptions
InputWaypoints: Click to add waypoints, drag them, see the list on a panel and delete them. The caller owns the Panel and the World, since there’s probably more stuff there too.
Minimap
Navigator
RunCommand: Executes a command and displays STDOUT and STDERR in a loading screen window. Only works on native, of course.
TitleScreen: A title screen shared among all of the A/B Street apps.
TripManagement: Save sequences of waypoints as named trips. Basic file management – save, load, browse. This is useful to define “test cases,” then edit the bike network and “run the tests” to compare results.
WaypointID

app_header: A standard way to group a home button back to the title screen, the title of the current app, and a button to change maps. Callers must handle the change map and home click events.
change_map_btn: A button to change maps, with default keybindings
checkbox_per_mode
cmp_count: Less is better
cmp_dist: Shorter is better
cmp_duration: Shorter is better
color_for_mode

find_exe: Returns the path to an executable. Native-only.
goal_marker: Draw a goal marker pointing at something.
