flash actionscript: I'm just wondering if there is a way to make motion tweens using AS. Let's say
I want to write a function that moves my_mc from point A to point B over X
amount of time. Or I want to fade in my_mc over an X period of time. How would
I do this?

Hello bwm_razel,

Have you tried the tween class?

It is in the documentation the Component Language Reference: ActionScript
Class Name mx.transitions.Tween
If you are using Flash 8 Pro.

Hope that helps,

No sorry, that class is only in Flash 8.

You may want to consider a 3rd party library or perhaps a book on scripted animation. Flash MX 2004 Game design demystified is a good one. :D

Here is the code for Flash Player 7

import mx.transitions.easing.Strong;
import mx.transitions.Tween;
easeType1 = mx.transitions.easing.Bounce.easeOut;
easeType2 = mx.transitions.easing.Strong.easeOut;
var scope = this;
var baseDepths = -16000;
//Tween
var tweenMenus = function (menuToTween, whatToTween, speed, endLocation,
functionToPlay) {
delete menuTween;
easeType = mx.transitions.easing.Strong.easeOut;
var _local3 = this[menuToTween][whatToTween];
var end = endLocation;
var _local2 = speed;
var _local1 = this[menuToTween];
menuTween = new mx.transitions.Tween(_local1, whatToTween, easeType, _local3,
end, _local2, true);
menuTween.onMotionFinished = function() {
scope[functionToPlay]();
};
};
MovieClip.prototype.pauseScene = function(pauseFor) {
var _local1 = this;
_local1.stop();
_local1.createEmptyMovieClip("timerClip", baseDepths);
timerClip.startTime = getTimer();
timerClip.pauseTime = pauseFor*1000;
timerClip.onEnterFrame = function() {
var _local1 = this;
var _local2 = getTimer()-_local1.startTime;
if (_local2>_local1.pauseTime) {
_local1._parent.play();
delete _local1.onEnterFrame;
_local1.removeMovieClip();
return;
}
};
};

tweenMenus(myClip, "_x", .75, 630, null);// myClip = mc - _x = property to
Teween - .75 = speed - 630 = end location, null = function to call when done
pauseScene(2);
stop();
