    Hey everyone!

    Just a small probelm: I'm doing some things in actionscript that require tweeing..... anyone know of a quick mathematical formula that will give me values that increase like a tween (ie small increments to large increments of gain) for example, an equation that
    produces something akin to 1, 1.5, 2.5, 4, 6, 9, 13
    But the thing is I;d like to be able to control the factor of inscrease..... say I want the values to jump sharply after a certain time, akin to tweening in or out...

    - Thanks!

    here's what you would do to have something like a tween with an ease out. (slowing down)

    //first declare your starting destination points
    onClipEvent(load) {
    x = 250;
    y = 250;

    //then declare your divisor that can be adjusted to your liking

    divisor = 10;

    onClipEvent (enterFrame) {

    //put you x and y positions of the mc in variables

    Xpos = clip._x;
    Ypos = clip._y;

    //find the distance between where you want to go and where you are

    distX = x - Xpos;
    distY = y - Ypos;

    //find the rate or increment to move the clip

    incX = distX/divisor;
    incY = distY/divisor;

    //move the clip

    clip._x += incX;
    clip._y += incY;

    Now this will move it and slow it down as it approaches its destination. Speeding it up as it appraoches its target is something I haven't done but I think it would be basically the same idea but with some mathematical changes. Just mess around with this code and see what happens.
