Defold Polygon Editor

A basic convex polygon editor that exports files for use with Defold.

Since it's possible to use convex polygon collision shapes with Defold, but the Editor doesn't yet support creating and editing them, I wrote a little program(with Defold) to fill that gap. So you no longer have to make a text file and write in vertex coordinates, in counter-clockwise order, by hand!

It's very, very simple and unpolished. Here is a short list of features:

• Load an image as a reference for your polygon (unscaled and centered at origin).
• In web version, drag-and-drop a .png or .jpg image to load it.
• Open and save polygon files.
  • Opening polygon files unavailable on web version
  • Uses Def-Diags for native file dialogs on Windows and Mac, and tries to use Zenity on Linux.
  • Can still save polygons in the application folder if none of those work.
• Highlights convex (and therefore invalid) vertices in red.
• Hold shift to snap vertices to an adjustable grid size.
