I'm wondering whether/how the following could be implemented in Gideros: image objects on screen where where only touches to a certain part of the image are being detected (e.g. only the non-transparent parts of a PNG).
In Corona I found two basic ways to do it: 1) (preferred) using a Bitmap Mask and set the object.isHitTestMasked property to true. or 2) using physics shapes
How would these transfer to the Gideros world?
