When I face the box2d vertex limit problem, resolved in some way in r198, and looking to the problem I found some solutions at least for other engines. One of the solution was to implement polygon decomposition, It could be a good idea implement this on the editor. It works creating a Body with several Fixtures. Those fixtures will have max 8 vertices and will share some of the vertices, so ill will simulate a bigger piece using smaller parts, which are stuck together.
In the editor maybe It can be implemented in a way to auto decompose the main polygon into pieces. Or maybe after adding more than 8 vertices it will auto decompose to the next polygon.
This way we don't decrease performance or project size importing multiple images.
The Actual Output of the Construct2 polygon system as I saw in the project file is:
<collision-poly>
<point x="0.163934" y="0.191257" />
<point x="0.315574" y="0.0846994" />
<point x="0.5" y="0.0437158" />
<point x="0.673497" y="0.0812841" />
<point x="0.822404" y="0.17623" />
<point x="0.916667" y="0.326503" />
<point x="0.956284" y="0.504098" />
<point x="0.910519" y="0.681011" />
<point x="0.818306" y="0.822404" />
<point x="0.678962" y="0.919399" />
<point x="0.528689" y="0.948941" />
<point x="0.529201" y="0.58312" />
<point x="0.469603" y="0.584785" />
</collision-poly>
so maybe we could ending having something like:
<collision-poly>
<vertices set="0">
<point x="0.163934" y="0.191257" />
<point x="0.315574" y="0.0846994" />
<point x="0.5" y="0.0437158" />
<point x="0.673497" y="0.0812841" />
<point x="0.822404" y="0.17623" />
<point x="0.916667" y="0.326503" />
<point x="0.956284" y="0.504098" />
<point x="0.910519" y="0.681011" />
<vertices>
<vertices set="1">
<point x="0.818306" y="0.822404" />
<point x="0.678962" y="0.919399" />
<point x="0.528689" y="0.948941" />
<point x="0.529201" y="0.58312" />
<point x="0.469603" y="0.584785" />
<vertices>
</collision-poly>
