Alright, I'm a little slow with trying to learn how beziers work. But for all of you people out there that also might be wondering how they work. I have found I little animation on Wikipedia that is amazing. How amazing? well, just by looking at this picture for about 10 seconds in about 15 minutes, I made my own little dynamic bezier curve in GM. Heres the little animation of it. 
<B>EDIT:</B> If anyone wants the .gm6 for reference, just tell me and ill post the link. Im also working on how to make more than just 3 control points for it. Its a bit tricky.<B>Controls:</B>Left-drag - move point.Enter - toggle lines between control points.space - move points to random posistion.<B>EDIT2:</B> Heres the editable, srry for the sloppy code in the 3-control point object. http://64digits.com/users/superdevon4/Bezier3.gm6I also added an animation picture (from wikipedia) to illistrate how more complex beziers work. Also heres the wiki link just in case anyone else is confused from the pix and/or .gm6http://en.wikipedia.org/wiki/Bezier_curve
Why not just post the link so you don't have to later?
well, im not going to unless someone wants it.
whats the point of a Bezier
say ur makin a terrain generation program, you might want to use smooth curvers, so you would use beizers.
I'll take a look at that .GM6
I'm interested.
alright, it will be up in a min, i just added an object with four control points, the one with only three is coded a bit slopy.
im trying to figure out a more efficient way of doing this in this method.
if you take a peek at how i coded the 4-control point object, you can see that its not really that hard, its just a lot of code. I think im going to redo this with arrays and more for statements to make it way more dynamic.
Those animations are rather interesting.
