rotation

[esromneb]

Hi, I'm trying to make an object spin accorting to the location of the mouse. For instance, I have a horizontal line as a movie clip, we will call this rotator, it's in a movie clip called holder. This is what my code looks like and it's almost right.

holder.rotator._rotation = Math.atan((holder._ymouse)/(holder._xmouse))*60;

(the code is a loop)

The line sorta follows the mouse but not really. It also reverses rotation when you move it above and left of the center of rotation. Please help.

The code you want to perform the maths is:

_rotation = Math.atan2(_root._ymouse-_y, _root._xmouse-_x)/Math.PI*180;

...so I'm guessing (can't be sure of your paths etc) what you want is:

holder.rotator._rotation = Math.atan2(_root._ymouse-holder.rotator.__y, _root._xmouse-holder.rotator.__x)/Math.PI*180; Slainte

It gets a bit confused whe hovering directly above the center point...
