atan2

[Desmond22 webforumsuser@macromedia.com]

Hi there,

I'm want to calculate the angle between 2 positions (pointa,pointb) on screen and I don't know how.
In flash I would use:

angle=atan2 (ydif,xdif)

where xdif and ydif are the respective x,y differences between pointa and pointb

but director dosen't have atan2.
Can anyone explain to me how to do it ?
Can anyone explain atan (simply)?

Use atan(y, x) - it's undocumented, but it works.
