I have an idea of hack.
Create a rectangle with a ball inside. This ball is connected to 6 lines pointing ends and middle the pool. Thus, each time that the ball ( hack) is placed over a ball game , the lines follow it. See picture for example.
this program would require an adjustment in opacity , and an option to disable the mouse pointer .
I think this hack is undetectable because , don't need cheat engine to modify the flash player.
Sorry not to be able to do this hack , I 'm not c ++ coder .
If someone would do and share. it would be really cool.
Thanks and bye.
