Blocks

Events

The map has several events. You can trigger actions to happen when these events occur.

On Map Ready

This event happens when the Map has loaded in your app.

This is a good time to add any markers, polylines or polygons to your app that you want the user to see as soon as your app opens.

On User Location Change

This event happens when the location of the user changes. It returns the coordinate object. You can use object blocks to get the properties of the coordinate object.

The coordinate object has the following properties:

{ target: Numeric ID for your app coordinate:{ latitude: latitude of point selected longitude: longitude of point selected } position:{ x: x-position of selected point on the Map component y: x-position of selected point on the Map component } }

On Press

This event happens when the user taps on the Map.

Output name	Output value	Data Type
Latitude	Latitude of selected position	Number
Longitude	Longitude of selected position	Number
position X	X Co-ordinate of selected position on map component	Number
position Y	Y Co-ordinate of selected position on map component	Number

On Long Press

This event happens when the user presses on the map for a longer period of time.

Output name	Output value	Data Type
Latitude	Latitude of selected position	Number
Longitude	Longitude of selected position	Number
position X	X Co-ordinate of selected position on map component	Number
position Y	Y Co-ordinate of selected position on map component	Number

On Marker Press

This event happens when the user clicks on a Marker that is on the Map.

The On Marker Press block returns an event object. This is an object which can be used with object blocks.

The event object has the following properties:

{ latitude: latitude of the selected Marker longitude: longitude of the selected Marker }

Functions

Add Marker

Adds a generic map marker to your map at the specified latitude/longitude.

This block takes the following inputs:

Input	Description	Data Type
Latitude	Latitude of marker's position	Number between -90 and 90
Longitude	Longitude of marker's position	Number between -90 and 90
Title	Title of marker (displayed when marker is clicked)	Text
Description	Description of marker (displayed when marker is clicked)	Text
Pin Color	Color of marker	Color

Add Icon Marker

Adds a marker of a selected image to your map at the specified latitude/longitude

This block takes the following inputs:

Input	Description	Data Type
Latitude	Latitude of marker's position	Number between -90 and 90
Longitude	Longitude of marker's position	Number between -90 and 90
Title	Title of marker (displayed when marker is clicked)	Text
Description	Description of marker (displayed when marker is clicked)	Text
Icon	Image to use as marker	Dropdown menu (select asset)

Add Polyline

Add a polyline to your map. This is an outline that connects several points on your map.

This block takes the following inputs:

Input	Description	Data Type
Coordinate	List of points to draw a line between. List can be any length.	List of objects. Each object must have the properties latitude and longitude. Latitude and Longitude must be numbers.
Stroke Width	Width of polyline	Number
Stroke Color	Color of polyline	Color

These blocks:

Will produce this polyline:

Note that polylines won't automatically create a closed shape. You would need to add a forth object with the properties latitude: 37 and longitude: -122 to the coordinate input of the addPolyline block above to close this triangular polyline.

Add Polygon

Add a polygon to your map. This is a solid shape that connects several points on your map.

This block takes the following inputs:

Input	Description	Data Type
Coordinate	List of points to draw a line between. List can be any length.	List of objects. Each object must have the properties latitude and longitude. Latitude and Longitude must be numbers.
Stroke Width	Width of outline	Number
Stroke Color	Color of outline (Only visible if Stroke Width > 0)	Color
Fill Color	Color of polygon shape	Color

These blocks:

Will produce this polygon:

Note that the polygon outline will automatically connect the first and last points in the list of coordinates.

Delete Markers, Polylines and Polygons

You can use the deleteAllMarkers block to delete all markers from your app.

You can use the deleteAllPolylines block to delete all polylines from your app.

You can use the deleteAllPolygons block to delete all polygons from your app.
