ActionScript 3.0 :: Place Objects Along A Motion Guide
Jan 15, 2009
I'm a beginner in Flash-AS, and I have been spending a lot of time on a (simple?) problem, still I didn't find anything that helps me. Here it is: I would like to place (via ActionScript) an object (let's say a ball) along a curve (free-shaped). The position of the ball is defined by a percentage in relation to the length of the curve : for example, 0% or 100% put the ball at the start or the end of the curve, 50% put the ball exactly at the middle of the curve... I don't need any animation, I just want to place the ball at the initialisation.

I have a simple problem, i have only the basic knowledge of AC3 like making simple tweens and doing some if else.
But as you can see, i have a triangle and a motion path. And lets say i need it to tween with an easeIn to the x location of my mouse, so the y location remains on the path, how would i do that?

i am using CS4 on a PC, and I have created my motion guide layers as I normally do, created a path, but when I scrub the playhead, the symbol just goes from point A to point B without follwing my guide. Also they are not snapping to the guide. I have not done a motion guide in a while, what am I missing here. Also where is the pallete to turn on object orienting?

Using actionscript I'm drawing a line. For the record let's assume it's shape is completely random. Can I use the line as a motion guide for another graphic? If so how? Can I convert the line to an array of Points somehow?

How do I move a graphic symbol along a motion guide dynamically. The guide is on a lyer of an mc residing on the _root. The graphic symbol is just below on another layer. The effect is to have the graphic symbol (a ball) appear to move randomly from the start of the motion guide a random distance along the motion guide and then change directions randomly. So the symbol would move a random number of points in one direction along the path then change direction and move a random number of points in the other direction while never actually leaving the stage.
The motion guide is NOT to be removed or drawn dynamically as it is the exact shape of the landscape in an image I use in the background of the overall animation so either the timeline needs to be manipulated for that mc or the symbol that is moving along the motion guide needs to be directed along the path dynamically.I tried the following code which I placed in the first frame of an action layer of the mc (mc resides _root) just above motion guide layer and it did not solve
_root.dot_ball_main_mc.onEnterFrame = function () {
var myVar:Number = Math.random()*(1-30)+30;
if (_root.dot_ball_main_mc._currentframe == myVar){
[code].....

So I am dynamically drawing lines. Pretend you run your flash movie, and click your mouse down, and move it around on the screen. It might have a curve, it might do anything, and once you release, the line is completely drawn. That part I can do no problem. I now want say, press a button and to have an MC appear on that dynamic line I drew, just like a motion path or guide, and then follow it until it comes to the end.

How do you hide the lines that form on the stage with all of the dots that form as you move a symbol from one spot to another on the stage?

Hopefully someone can give me a hand with this.I'm trying to create motion using scripting instead of a guide path or tweening event which should occur like this:Stage default size (550x400)Instance of a ball (in a movie)Ball starts on top left corner of stage then travels to top right, then travels to lower right, then travels to lower left, then travels to top left, then repeats.Basically the ball should just travel clockwise around the inside border of the stage.The script I'm trying to setup is based on three frames.
First frame:
_x=30;
_y=30;
xspeed=20;
yspeed=20;
[code]....
After this I seem to just run into problems. Each time I try and set the logic for the ball to change direction and head back to the left once it reaches the bottom of the stage it either just stops, or bounces slightly back and forth in the lower right hand corner.

Is there seriously no way to convert a vector graphic into a motion guide for Flash? Are the Pen and Pencil tools really the only way to define the path for a motion tween? I have CS3 (Flash, Illustrator, PhotoShop). I just got the trial version of CS5. I have a subscription to[url]... I have searched these forums and the internet in general for hours.
All I want to do is move a symbol around in a circle, but my pen/pencil skills are not sufficient to create a circle. Editing the CS5 motion path has proved exceedingly tedious and not round. There's a perfectly good circle tool in all four applications...

Is it possible to draw motion guide/path for a mouse position based movement?
For example if I have path the is like letter H. I would need to write many clauses/conditions for the borders of the movement. It would be a LOT easier if there would be some solution that makes the object always to stay on the defined path when moving..

-Take a circle and place it in the center of a square scene.
-Make a rectangle and snap its left edge to the circle's center.
-Make another rectangle and snap its left edge to the right edge of the first rectangle.
How would you make it so movement doesn't happen at the registration point but on the whole arm. Say i ran a rotation script on the upper arm with +=1 and the lower arm with +=2. How would you place the parts, what format would they be converted to and what would the script format be. Multiple methods would be welcome of course!

I used the liquid Flash layout file from this site , but i got one problem.I placed the script in a layer called actionscript and on frame 1, under it there is a other layer called background. I placed in just a square with a gradient color and made it a movieclip. I also placed this on frame 1. Everything is working perfect from this point but when i want to place a keyframe on frame 10 in the background layer and make a motion tween so that the background fades in from 0 opacity to 100, it doesn't work.

I am creating series of rectangles dynamically and placing them into a grid pattern under a function called createGrid(). I am than creating another single larger rectangle in a function called drawTimelinecontainer. I than want to place all the objects that were created in the createGrid() function into the object that was created in the drawTimelineContainer function. It seems I get an undefined property error when I add it to the display list like this timeLineContainer.addChild(timeLineCell). Is there a way to do this and have the creation of both objects done in separate functions?

I have for a long time tried to get rods beeing placed side by side without overlapping after dragging. I don't succeed. This side shows that it can work: [URL]. I want my objects beeing placed side by side or over each other, not overlapping and no space between, just like in thos link.
Code:
var mcArray:Array = new Array();
var lastClicked:MovieClip;
function drag() {
this.startDrag();
lastClicked=this;
} function dragEnd() {

Ive got one index-file on _level0, from which I load another file into _level1, on top of _level0 covering it completely.
I would like a single (not all) object on _level0 to show on top. Is that possible?
Layers would only work, if Im not misstaken, on a single level, so I guess thats out.

I've been working on this for over 3 hours and it is about to drive me crazy! I was one of those people who never paid attention to math in high school because i thought i would never use it ( i knew i wanted to be an artist/designer of some sort). But now of course, that attitude is coming back to haunt me. I'm using a for loop to place several objects on stage. I need a formula that will space objects along the x axis evenly, and center all the objects on the stage. Kinda like if you use the align panel in flash to distibute the vertical centers of several objects to the stage, if that makes sense. If there is only one item, it should be directly in the center of the stage. If there are 2, it should place them in the center of the 2 halves of the stage, and so on for howeve many objects there are. I also want a buffer of about 25 pixels on either edge of the stage so that no object is ever on the very edge of the stage. I made a simple diagram to illustrate:

I don't understand how it's possible to have a lot of objects on the stage and be able to manage the motion tweens with all of them, but ALSO manage which objects are in front and which are in back of each other. I have a military type animation and there is a lot of action going on, and there are times where I need some of my guys to be in front of objects, and times when they need to be behind.
I don't know how to manage the objects in regards to layers and motions in a way so I can get the objects in the order I need them to be (like which item goes in front of the other).
Does anyone have any tips or a way that I can manage my objects and motions and be able to sort them on the stage so that I can arrange the objects how I need them to be in regards to placement and which should be in front of other objects?

I want to be able to create and place objects on the stage dynamically and remember their location. I'm guessing the best way would be saving the object type and location in an array? Just wondering if there is a better way before I start coding.

I'm new around these parts (I literally signed up about 3 minutes ago!). I'm a high school student who just started using Flash about a month or two ago, so I'm far from advanced, though I have tackled some of the basics. In class I'm working on an art portfolio site but in my spare time I'm making a virtual dress-up doll (you know, the kind where you can pick up the clothes and drop them on the figure to mix and match outfits).Learning how to make drag-and-drop objects was very easy and there are lots of tutorials on it but what I can't figure out is how to get objects to "snap" into place. I want it so that the doll's hairdo's snap into position because they look kind of stupid when placed incorrectly.

I have to marbles (balls) lets call them m1 and m2, I am trying to have m1 move across the stage and hit m2, then have m1 stop and m2 continue moving off the screen at the same rate as m1.
I am able to get m1 to move over (left to right) and hit m2 and stop using hitTestObject, but I can't figure out how to get m2 to move to the right.

I have a CS4 document with many objects, motion paths over multiple layers. I want to scale everything, including the motion paths of each object. I've tried to do this by Clicking 'Edit Multiple Frames', then 'Selecting All Frames' and finally scaling everything via the Transform panel. Everything appears to have been scaled apart from the motion paths. Is there a way to do this?

I'm trying to create a flash demo for my prof and we want green dots to move randomly across the screen without ever overlapping each other.I saw the kirupa tutorial on random motion which is really good. I'm wondering if I can add something to the code so that the dots won't overlap, (as soon as one touch another they move away) as they move.

I have an object that gets attached to the stage everytime I click (like a side shooting game). What I want is the object to have a speed in a specific direction. I got it to work by the code-
Code:
if (total_bolt_no>0) {
var bolt_name="bolt"+total_bolt_no;
var bolt_n:Sprite=this.getChildByName(bolt_name) as heroweapon;
[Code].....
The problem that arises is that when I spawn another object the previous one becomes still. I tried using the for loop but everytime I click the angle also changes, thus changing the speed of all attached objects.

I am using the random motion code found here at Kirupa. [URL]I have the code working fine but I have a question about fixing it to my needs. The way it is now, you change the height and width variables so that the objects don't move off the screen. This works fine, if you are using the whole screen area at:
