Rotation

[SpasticMOose]

hey, i remember lookin at a post a while back and someone had asked how to rotate somethign according to the mouse postion. i believe it was SubKloda who posted a beatiful response that needed only 1 line of actionscript. something like:

onClipEvent (mouseMove) {
this._rotation = Math.atan(_xmouse/_ymouse)*(180/Math.PI)
}

or along those lines atleast. can anyone give me a lil help??

thx!

I think something like this would do it:

onClipEvent (mouseMove) {
      this._rotation = Math.atan2 (_root._ymouse, _root._xmouse) * (180/Math.PI);
}

The "atan2" function does all the quadrant checking for you since "atan" (by definition) only returns principal values (from -pi/2 to pi/2).

Good luck.

i didnt know what the atan2 was for, thx for the help

btw, this is the one that works:

onClipEvent (mouseMove) {
this._rotation = Math.atan2 (_root._ymouse-this._y, _root._xmouse-this._x)*(180/Math.PI)
}


btw, how do you get the code to be in grey and centered in the post with diff text properties etc.. ??

cheers
