Take careful note of the differences.
Which is that the y axis is flipped.flash uses radians to measure angles not degrees,

The maximum rotation around any Cartesian coordinate system is 360 degrees.
In Flash if you are moving clock wise this will be a positive number
in degrees until you reach 180 degrees.
If your are moving counter clock wise this will be a negative number
until you reach -180 degrees

Angles.fla

Result

The SharedObject class is used to read and store limited amounts of data on a user's computer or on a server. Shared objects offer real-time data sharing between multiple client SWF files and objects that are persistent on the local computer or remote server. Local shared objects are similar to browser cookies and remote shared objects are similar to real-time data transfer devices
