ActionScript 3.0 :: Using The Tween Class To Move Them Around The Screen?
Feb 4, 2009
I have various instances of an object that I want to animate.
Code:
var obj = new obj_class();
I'm using the Tween class to move them around the screen.
Code: var tw:Tween=new Tween(obj, "y", None.easeNone, y1, y2, framerate);
tw.addEventListener(TweenEvent.MOTION_FINISH, removeObj);
addChild(obj);
I start the animation on a button press.Code: stage.addEventListener(KeyboardEvent.KEY_DOWN,key_down); When I click the button the animation of the instances seems ok, but if I click the button quickly sometime the animation doesn't end, the object seems freezed in the middle of the screen and also the MOTION_FINISH isn't called.

I'm trying to achieve a simplified version of the move to screen area and zoom nav similar to: [URL]. I've read and completed the macromedia tweening tutorials [URL] and gained overview of tween class etc., So, I created an example (credit :sophistikat) using the macromedia tween class:
Code:
import mx.transitions.Tween;
import mx.transitions.easing.*;
myBtn.onRelease = function () {
//first move to center in one second witih no delay
main_mc.tween("_x", 50, 1, "easeinoutElastic");
main_mc.tween("_y", 50, 1, "easeinoutElastic");
// and in 2 seconds scale closer
main_mc.tween("_xscale", 150, 1, "easeinoutElastic", 2, true);
main_mc.tween("_yscale", 150, 1, "easeinoutElastic", 2, true);
}
The script in layer 1, the bt in layer 2 and the main_mc in layer 3 - all correctly 'instanced'. But not working - the main_mc isn't moving and then zooming in when btn is clicked.

tutorial where when you click on a movie clip it moves to a certain location on the page and then zoom in and makes it a certain size. Also i want it to move back to its original location if you click it again.I want the move and zoom to be smooth so the users can see it move across the screen then gradually get bigger.

I'm creating a image gallery and I have this code when I click on image
html4strict Code:
imageBox[curCell._name]._visible = false;
imageBox[mc._name].fadeIn();
What I want to setup is imageBox[curCell._name] to move out to left while fading out.
And imageBox[mc._name] moving right of the screen to center while fading in...
get a tween function to left and a tween function to center from right?

So, I have a tween where a movie clip starts at 0 alpha and ends at 100.. I want to move the clip to a new place on the stage, but when I do it creates a motion path.. Edit multiple frame doesnt work either, so how does someone move a tween if the tween doesnt have a tween path?

I am having some dificulty making a path for this enemy i'm trying to create... cause i want him to rotate + move, then stop, then shoot, then rotate back and move off screen... Its easier if you see it.. you can download the swf file in the zipped archive to demonstrate what i mean. I did it there with tweens. Anyway.. i tried and make it but i'm a little stuck on the stopping part... you can also see what i did in the fla file attatched...

Now I am using the Tween Class to move some boxes in my movie, now I can move the first mc and then another mc after the first tween has finished with onMotionFinished but I was hoping someone could help with how do I start the second tween when the first mc has passed a certain _x coordinate. ie starting the second mc moving while the first tween is still moving.

If i have a clip with a bunch of stuff inside it (on layers) like other clips, bitmaps, etc. and perform a tween on that clip (via tween class), the stuff inside the clip seems to alpha at different rates.
For instance, i have a clip with an empty movieclip which loads a bitmap image and on top of the bitmap image, i have a gradient feathered edge (.png) bitmap and on top of that I have some dynamic text (embedded fonts).
The bitmap is supposed to create a feathered edge on the photo but since they alpha at different rates, you always see the hard edge of the photo...
is there a solution like cacheAsBitmap which would let the whole clip alpha at once? If it's cacheAsBitmap, i must be using it incorrectly, b/c it's not working!

Am trying to use the Tween class to scale and move a movieclip. Now the movieclip is within the loader, so I need the motion to be controlled by the percentage loaded. Now the code to move the movieclip to its final position is:
var xscaletween:Tween = new Tween(mstone, "_xscale", Regular.easeOut, mstone._xscale, 220, 6, true);
But this is the final location, I want to be able to change the properties of xscaletween, yscaletween, xmovetween and ymovetween as per percentage loaded.As in, within this final boundary limit of the tween, I want, for example, xscaletween, to scale only till 140 till percentage hits 50. Is this possible?? If not is there a workaround?Or do I have to use new tweens within each percentage limit?

I am trying to understand the thinking behind motion tweening using AS3 (rather than doing it on the timeline).I am trying to create a simple platform game, and while this is simply a learning project, I have an movieclip instance on the stage, and using basic x+5 logic I can get the instance to move left and right on the stage accordingly.Trying to make the instance 'jump' is a bit trickier. This is the code I am using:
ActionScript Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;[code].....
I thought this code would move the instance from it's current y-position and tween it to it's highest jump point. From here I planned to use a MOTION.FINISH event to tell it to tween back to it's original position.Something strage happens though, rather than tween from the current y position and move up, the instance instantly transforms it's position to y+100 and then tween back to the original position. So it kind of turns out that it is the second part of the jumping action that I want to create.

Is there any way to make a movie clip start at a given x and y point, and ends at another x and y point, in 90 seconds?m not getting a good result.The main problem is, I want the movie clip to travel along a straight line. And by this code below the "b" movie clips makes some curves.Heres what Ive done.
"p" is point movie clip
"b" is ball movie clip
fullTime = 90000;_currentTime = fullTime;oldTime = undefined;onEnterFrame = function () {if

If you try to make a movie clip travel along a rectangle diagonal within 90 seconds, the movie clip makes some curves.

What I want to do is tween a number from lets say 0 to 50 using the Tween class. The below is an example of my tween but it wasn't working (*NOTE* i'm using TweenExtended but if you change the tween to Tween only it will be the same thing, i just have a habit of using the TweenExtended class):

I would like to select all the instances along a motion tween, at each keyframe, and move them over the same amount, all at once.
It can be done in a classic tween using "Edit Multiple Frames".

Does anyone can explain, why on the timeline in CS4 I can move only those motion tween which have the same long? Yet, It's without sense.

Ok -- so I figured out how to tween in CS4, but how the heck to you adjust the tween? If you decide you want it to be a few frames longer or shorter? It wont let you drag the tween point! The only thing I've found that works, is deleting the tween and then making a new one. Which, is absolutely rediculous -- I know there has to be a way to edit it once you make it.

When using AS2 a mc when moved via AS would slide to the new position. I have some AS3 code, which when the left or right buttons are pressed moves the mc to a new position, but it just jumps to the new position instead of sliding.How would I alter the code so that it slides to the new position instead of jumping? I've searched everywhere and tried to add tweenLite but I really am stuck
Here's the code I'm using -
illleftButton.addEventListener(MouseEvent.MOUSE_UP , leftbuttonill);
function leftbuttonill(event:MouseEvent):void{
if (MovieClip(root).mainContainer.illustration.x < -40){

I'm getting into flash and am having a great time. I'm working on games and want to join a community that is active that I can hopefully learn from and contribute to. It will be a few months before I can probably be of much help but I certainly hope I can learn more from the thread. With introductions out of the way...I can't get a simple MC to move given this code:

I found a cool 3D menu at developphp.com and want to fit it into my hud. I can get the button navigation working, add internal animations (eg, glowing) but for some reason I can't get the dang thing wired to a button.I put the object in another MC container with the hopes of accessing it that way but no luck.

I understand that motion tween is a new form of tween in CS 4 however I am unable to move a keyframe within the time line? am I missing something? I would hope I could select the keyframe (diamond shape) and move it around the timeline but apprently Im missing something.. I am not able to do a cut and copy either... is this normal behavior?

It is very frustrating to move the diamond shape of the motion tween or to even delete an unwanted diamond shape on the timeline.

I'm making a game like Super Smash Bros., and so far it's pretty good. However, I came across one problem: I can't get the camera to move. Basically, I somehow want the camera to always show 100% of everything on the screen. If a character goes really far down, I want the camera to zoom out. If they're next to each other, I want it to zoom in. How do I do this? I didn't get a single dang response to like the last 4 posts I made.

I have just re-installed Flash CS4 onto two Vista machines (laptop and desktop) and the response time of the authoring screens is ridiculously slow on both. For example with the Actions Panel displayed, it takes 18-20 seconds to move the cursor along a line of code.
All other CS4 appilcations such as Photoshop, Fireworks and Illustrator all work very well and have no such problems. The computers have plenty of hard disk space and RAM (eg. Acer Aspire Desktop new computer with 1Tb disk and 3Gb Ram) and the CPUs are running at less than 50% (task manager) and there are no other apps running. I have disabled Kaspersky Internet Security 2010 with no effect.

This the code to move my hero mc around the screen However, when you click directly under or over the mc it doesn't move. When I say directly above I mean the angle not the distance. ie: I am well above the mc but it doesn't move. Little kids are going to play this and it needs to be more responsive or they get frustrated.
