Xonix floodfilling

This is a better forum for the continuation of this thread:

https://forum.unity.com/threads/xonix-polygons-filling.1287575/

which was started by @Geckoo but wasn't really relevant to Unity Scripting and was mod-locked.

@Geckoo asked:

> how (and when) could I determine the point from which the filling process starts ?

Read my post here, specifically part 2:

And for this:

> How may I be sure that I have a closed polygon ?

You ALWAYS have a filled polygon: the screen boundaries catch everything.

The floodfill routine (see Bunny's notes above) can give you the list of cells that constitute an "enclosed area."
