Adding the Polygon Editor to a map

Add the Polygon Editor overlay to a WRLD Map. Click on the Draw Polygon button to begin drawing. Click on the Edit Polygon button to modify an existing polygon.

This is an optional component with a few dependencies. To use it, you will have to include polygon_editor.css and polygon_editor.js, as shown in the code sample below.

It is also recommended when using the Indoor Control that you hide it while drawing/editing. This is to avoid accidentally changing floor while drawing.
