Properties​

MapOrigin​

LatLng MapOrigin

The LatLng that the map uses as its origin. Note that the map's position can be changed through its transform without affecting the MapOrigin 's location. However, large distances between the map's center (MapCenter) and its origin can lead to loss of precision, so setting the map's transform directly is not recommended.

MapCenter​

LatLng MapCenter

The center of the map's viewable area

MapRadius​

double MapRadius

The radius of the map's viewable area, in meters

MapScale​

double MapScale

The map's scale

ActiveMapTiles​

IReadOnlyDictionary<ulong, IMapTile> ActiveMapTiles

All active IMapTiles in the scene

IsMapCenteredAtOrigin​

bool IsMapCenteredAtOrigin

If true, the map will always be centered at the scene's origin

Events​

MapTileAdded​

event MapTileAdded()

Event that's raised when a new IMapTile is added to the scene, after all of its meshes have been generated by feature builders.

MapTileRemoved​

event MapTileRemoved()

Event that's raised when an IMapTile is no longer in view, just before its IMapTileObject is returned to the pool.

MapRadiusChanged​

event MapRadiusChanged()

Event that's raised when the map's radius changes.

MapCenterChanged​

event MapCenterChanged()

Event that's raised when the map's center changes.

MapOriginChanged​

event MapOriginChanged()

Event that's raised when the map is repositioned back to the scene's origin.

Methods​

OffsetMapCenter​

void OffsetMapCenter(Vector3 offset)

This method is called to offset the map view's position.

    Parameters:

    offset - The offset, in Unity's world space.

SetMapCenter​

void SetMapCenter(in LatLng latLng)

This method is called to update the map view's position (in response to changes in the device's GPS, for example).

    Parameters:

    latLng - The map's center, in lat/lng coordinates.

SetMapCenter​

void SetMapCenter(Vector3 center)

This method is called to update the map view's position (in response to changes in the device's GPS, for example).

    Parameters:

    center - The map's center, in Unity's world space.

SetMapRadius​

void SetMapRadius(double mapRadius)

This method is called to update the map's viewable radius (when the map is zoomed in or out, for example).

    Parameters:

    mapRadius - The map's viewable radius, in scene units.

SetViewableArea​

void SetViewableArea(in LatLng latLng, double mapRadius)

This method is called to update the map view's position and viewable radius (in response to changes in the device's GPS or if the map is zoomed in or out, for example).

    Parameters:

    latLng - The map's center, in lat/lng coordinates.

    mapRadius - The map's viewable radius, in scene units.

SetViewableArea​

void SetViewableArea(Vector3 center, double mapRadius)

This method is called to update the map view's position and viewable radius (in response to changes in the device's GPS or if the map is zoomed in or out, for example).

    Parameters:

    center - The map's center, in Unity's world space.

    mapRadius - The map's viewable radius, in scene units.

SceneToLatLng​

LatLng SceneToLatLng(Vector3 scenePosition)

Converts a position in Unity's world space to a location in LatLng coordinates.

    Parameters:

    scenePosition - The position to convert.

    Returns:

    A set of lat/lng coordinates for this location.

LatLngToScene​

Vector3 LatLngToScene(in LatLng location)

Converts a location in LatLng coordinates to a position in Unity's world space.

    Parameters:

    location - The location to convert.

    Returns:

    A world space position.

WebMercator12ToScene​

Vector3 WebMercator12ToScene(in WebMercator12 location)

Converts a location in WebMercator12 coordinates to a position in Unity's world space.

    Parameters:

    location - The location to convert.

    Returns:

    A world space position.

MetersToScene​

double MetersToScene(double meters, double latitude)

Convert a distance in meters in the real world to Unity scene units. Note that latitude is required here because our map uses Web Mercator projection, which causes distances to stretch as you approach the poles.

    Parameters:

    meters - The distance, in meters, to convert.

    latitude - The latitude at the location at which the conversion applies. A reasonable value for this would be the latitude at the map origin.

    Returns:

    The distance in Unity scene units.

SceneToMeters​

double SceneToMeters(double sceneUnits, double latitude)

Convert a distance in Unity scene units to meters in the real world. Note that latitude is required here because our map uses Web Mercator projection, which causes distances to stretch as you approach the poles.

    Parameters:

    sceneUnits - The distance, in Unity scene units, to convert.

    latitude - The latitude at the location at which the conversion applies. A reasonable value for this would be the latitude at the map origin.

    Returns:

    The distance in meters.

SetMapTheme​

void SetMapTheme(MapTheme theme)

Sets the current MapTheme

    Parameters:

    theme -

RefreshMap​

void RefreshMap()

Refreshes the map at the current location.
