- Sun 18 Jun 2017, 15:52 #62288 Each collision mask has to be a convex polygon (any number of vertices), but you can have multiple collision masks, so you can simulate any complex shape (even concave ones)
You can't do it:

But you can do it:

Take into account that increasing the number of vertices and collision masks reduce the performace per collision test, specially in HTML5, but I have never tested it though...

I should be studying now :/
