Rotating eye effect

[justgeor]

hey im trying to make a game where theres a gun that aims at the cursor... i looked at a tutorial for "the rotating eye" which basically made the eye look at the cursor.

it said to use this code:

// eye rotation
a = eye._y-_ymouse;
b = eye._x-_xmouse;
angleA = Math.atan2(a, b);
degrees = angleA/(Math.pi/180);
setProperty ("eye", _rotation, degrees);

i changed it so it wasnt eye and it was gun to work for my game.. but when i try to play it it says:

There is no property with the name 'pi'.
degrees = angleA/(Math.pi/180);

anyone know what to do???

I would suggest posting this in one of the Flash forums here instead of the lounge... more likely to get a reply.

The error most likely is related to an object not having the right name in your movie.
