more angle problems

[mr_malee]

ok this one seems to be a tough one. Well for me anyway

is it possible to use angles to determine whether an object has passed another object. Have a look at this




you see that this cannot work, also checking the axis seperatly wont work either. Because the same problem can occur, also note that gravity can effect the object, so the object can be released parallel to the center and might fall below the center before it visually passes the center

any help?
