    Angle calculation but a different approach

    Calculating the angle between the diagonal axis and the bottom line of the stage...

    angleCalc = Stage.width / Stage.height;
    myRatio = 1/angleCalc;
    realAngle = -(90-(myRatio * 90) / 1);
    nice try, I loved the way you tried to solve the problem, but it's just not the way it works.

    It goes like this: there are magical "sine" and "cosine" functions. They take angles and return values that correspond to linear coordinates in some way. There is "tangent" function defined as a ratio between sine and cosine (and so the ration between corresponding x and y values). Finally, there is inverse function called "arctangent" that takes ratio of x and y values and returns corresponding angle. You should learn about all of them 1st before scripting anything.

    But, of course, if you just want to take a shortcut, it is there, too.
    who is this? a word of friendly advice: FFS stop using AS2

    hi realMakc,

    first of all thanks for your response... Actually i was aware of those things that you mentioned above... like sine, cosine, tangent and so... and that was the first and noobish attempt that i've written there... after doing some search about radians, angles, and Math.atan2 I found examples like you posted in the link. Strangely they didn't work for me but the code that you provided with that link seems to work just as i want...

    THANK YOU
    case closed.

    P.S. how do members edit their thread and put a " [RESOLVED] " text in the header?
