Ming 0.3 uses AS1 which can be used for Flash 6-8.
many external code libraries are in AS2 and Ming cannot compile them.
but because AS2 compiles down to AS1 in the swf so if AS2 compiled is compiled and loaded into a Ming swf the AS2 classes are available and calling AS2 clases from AS1 works.
above example demo is for ASWing and
probably any AS2 library can be used like Fuse Kit and
Sandy 3D.
download AsWingLib-7.swf from code.google.com/p/aswing/ our build your own with mtasc + AS2 ASWing source code.
just compile the needed classes using
MTASC and use LoadMovie or SWFPrebuiltClip to add them to Ming swf or
