GiderosPlayer.exe assertion failure when passing empty argument list to b2.PolygonShape.set

ndoss

The following code:

shape = b2.PolygonShape.new()
shape:set()

causes the GiderosPlayer to shutdown with a runtime assertion:

Program C:\Program Files\Giderso\GiderosPlayer.exe
File: ..\external\Box2D_v2.2.1\Box2D\Collision\Shapes\b2POlygonShape.cpp
Line: 122
Expression: "3 <=count && count <=8"

I know this is invalid usage of the "set" method, but thought I'd report this since it's the only time that GiderosPlayer has asserted on me.

thank you for the bug report

In my case I can't set anything. I'm most probably doing something wrong
i've tried vertices = { {0, 0},{0, mHeight}, {mWidth, mHeight}, {mWidth, 0}} and
vertices = { {x=0, y=0},{x=0, y=mHeight}, {x=mWidth, y=mHeight}, {x=mWidth, y0}}

and after
shape:set( vertices) the compiler keeps saying "expected NUMBER, got table" in those cases. What am I doing wrong?
