Hi, really getting into the flash engine many thanks Couple of things I can't figure out -

- in the manual it states that vertices must be specified in counter-clockwise order, to me the coords given look clockwise (and work clockwise)?
(-1.0, 0.0) (1.0, 0.0) (0.0, 2.0)
Perhaps are the axis different for flash or have I missed something? To me they seem to draw correctly when specified in clockwise order starting at any given point.

- When I create a polygon with a density of 0 (fixed), objects on top of it bounce up and down as if there is a problem with the surface. This is not the case with a polygon with density > 0.

Thanks

Most applications use +y up, but flash uses +y down which is why the co-ordinates look clockwise.

Another way to state the requirement: the order must be CCW around the positive z-axis of the right-handed coordinate system.
