Since it’s possible to use convex polygon collision shapes with Defold, but the Editors don’t yet support creating and editing them, in the last couple days 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 a very simple, unpolished thing at the moment, but I plan to gradually add more features and improve usability in my spare time. Once you’ve made the polygon how you want, click the save button and it dumps out a “.convexshape” file in its base folder. Here are screenshots of the editor and some of the resulting bodies in a Defold test project.
The project source files are on github here: https://github.com/rgrams/defold_polygon_editor
I hope someone besides myself finds this useful! (until the editor does this stuff . . . hint hint)
