ActionScript 3.0 :: Object Moves With Scrollrect?
Aug 18, 2011
I have a scrolling background that is 1320 x 1000 big. I'm using a sprite as a container where my background canvas is placed inside of it. Additionally I add (via addChild) a score sprite inside of the background sprite (the one that holds the bg canvas so the score appears on top of the bg canvas).The goal is that when I add a score it shall be stuck to the background (even when the scrollrect moves; it shall have a fixed position on the background).The problem is that this doesn't work because when the score appears it moves with the scrollrect and this is not what I want. I already tried it with globalToLocal but had no success yet. Probably because I don't really understand globalToLocal (and vice versa)These are some code excerpts:
Code:
private var backgroundBitmapData:BitmapData = new BitmapData(1320, 1000, false, 0x000000);
private var canvasBitmapData:BitmapData = new BitmapData(1320, 1000, false, 0x000000);

I'm working on a school project. Below is an image of what I am working on. My cursor in this movie is the heart. When I move my mouse over Hello Kitty she jumps -- but only once. How can I get her to keep jumping when my mouse is over her, and make her stop jumping when I pull away?
Also, because I am new to ActionScript I might have messed up with the motion of the animation. Hello Kitty used to jump continuously without me doing anything. Then I copied the motion code into my ACTIONS layer and put stop(); in the Hello Kitty object code. So, she doesn't jump all the time anymore, just when my mouse moves over her... but she only jumps once and that is the problem. I want her to keep jumping as long as my mouse is over her.

To start things off, I use Flash CS3.moving menu that moves on its own when the mouse moves around it. Like the menu moves up when the mouse moves down.[URL]i have found similar tutorials for what i wanted.. but they are AS2 or older versions of flash..and what i needed is more along the lines of AS3 as that's what my class is learning and using.Does anyone know of an AS3 or anything that works with Flash CS3 tutorial thats what I'm asking?

I have a few MovieClips that are motion-tweened via the timeline. I have a function that places a glow filter on the tweened movieclip. The glow works, but... the movieclip no longer moves. I found that if I tween via actionscript (AS3) that it does tween. However, I have about 1000 movieclips, all w/ different tween properties.Is there a (much easier) walk around or am I going to have to code for a few days/weeks?

I wrote a class for an object that as soon as it is created moves around the screen and can create another object (replicating itself). That seems to work fine for a while, but after like 20 or so objects on the screen things slow down a lot! I create the first object on frame one. The rest is all done by the objects themselves.
Would it be better if the objects did not move around on their own, but rather through a loop on frame one or does it not matter? I am working on a simulation that should go up to over 100 objects, but with this problem can't get there. The object is just a movie clip (imported png picture about 4 by 7 pixel, not animated). I was going to replace it with an animated one later, but that seems unlikely now.

Is it possible to use scrollRect without the flash.geom.Rectangle class?I know the scrollRect can be used like this:import flash.geom.Rectangle; myMC.scrollRect = new Rectangle(10,10,100,100);I need to make a flash which doesn't extends outside the stage (bacause loading it from another flash will expose anything outside the stage area). Using a mask is an option, but scrollRect seems very interesting because it would be easier and give greater performance.But I can not import the flash.geom.Rectangle class (and it seems overkill to import a class just to set x,y,width and height)How can use scrollRect without the flash.geom.Rectangle class?

If we have a Bitamp with more than 16777216 pixels (or one side larger than 8191 px) Flash 10 doesn't show it (Flash 9 and earlier has smaller limits even).One solution to this is to use scrollRect to limit the size displayed.OK, that works.
But Flash 10 has another problem, if we use any 3D property (rotationX, z, etc), flash transforms your MC in bitmap, so we can reach the above limit even when we are not working with bitmaps...A bigger problem is that although our MC could be really small (at least less than 16777216 pixels), when we apply a 3D transform like rotationX, the displayed MC can grows enough to reach the limit. And... we can't use scrollRect with 3D MC. But we have a trick here too, there are two ways to use scrollRect with 3D:
1. Create a 2D parent, then create the 3D displayObject inside of that parent.
2. Set cacheAsBitmap to true for the 2D parent.
3. Create a grandparent container to hold the first two items.
4. Set cacheAsBitmap to true for the grandparent container.
5. Apply scrollRect to the grandparent container.
These methods are really differents, with the second I couldn't use scrollRect to avoid reaching the bitmap limit. I think that's because in the second we apply scrollRect to the parent and 3D to the child, so nothing breakes our child from growing.With the firs method we apply scrollRect to the child, and the 3D property to the parent.
Code:
var p: Sprite = new Sprite();
var c: Sprite = new Sprite();
p.addChild(c);

I have some actionscript, and it scrolls the scrollRect, but there is a catch. It doesn't completely scroll it. It lets me scroll down until it's halfway and stops. I can still scroll up to the top, but the problem is unerving. I can't find a fix for it.

There are two basic ways of panning a view in Flash. One is to move the display object (and use a mask if necessary). The other is to use scrollrect. Today I noticed a small, but annoying effect of scrollrect. Scrollrect's can't have true Numeric positions-- they are automatically snapped to the nearest pixel.
When moving at very slow speeds, the effect is noticeable. In this example you can switch between two modes of panning, sprite movement with mask and scrollrect:
http://lab.wx3.com/scrolltest/ (view source enabled).
In the default mode, the circles move smoothly.
In scrollrect mode, the circles seem to stutter because the scrollrect is snapping to the nearest pixel.found a way to make a scrollrect move smoothly at slow speeds?

in order to increase performance of a scrollRect i must cache the vector as a bitmap, otherwise the scrollRect will be simply a less performant mask (info source).however, i can't seem to move an object/scrollRect once i've applied cacheAsBitmap. why?

{
//Imports
import flash.display.Screen;
import flash.display.Sprite;

I am having a problem with ScrollRect. I am unable to upload a file( i don't know why..i am getting upload error msgs). So i have quoted the code.
ActionScript Code: import flash.geom.Rectangle;
var container:MovieClip = container_mc;//container_mc is in timeline(its widht is 600 )
var window:Rectangle = new Rectangle(0, 0 , 400, 100);
container.scrollRect = window;
container.cacheAsBitmap = true;

I'm having a problem that involves scrollRect and getBounds. In short, getBounds is reporting an old value not accounting for scrollRect changes during that frame. Example:
ActionScript Code:
var shape:Shape = new Shape();
shape.graphics.beginFill(0);

I have two pieces of code, that won't work together.First: this makes a hitTest on an mc to make it run on rollover:
Code:
onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse, _root._ymouse, true)) {
if (this._currentframe<this._totalframes) {
nextFrame();
[Code]...
Each work seperately, but they won't together. How do I get around this?

I'm having trouble using a scrollRect on an object instance on the timeline that has a motion tween. As soon as I apply the scrollRect to it, the object just stops! I've attached a simple fla that shows what I'm talking about.
Simply comment out this line in the first frame's actions to see the oval move across:
Code:
oval1.scrollRect = window;
The actual application I'm making is using a scrollRect on a custom list control, where each item in the list is a symbol in the library. It works great, except if I try to move my list around using a motion tween (the list still works, but the list doesn't move in the motion tween). As soon as I remove the code to apply the scrollRect, it works but the list fills the screen!

I'm trying to make a full browser webpage that utilizes the scrollRect type of class to pan around a movieclip that contains other movieclips and so on. The problem I run into is that when the browser window is resized that panning doesn't go with it. So panning to all the edges becomes impossible. I've tried a bunch of different stage resizing techniques but none of them give any good results. Here's the actionscript I'm currently working with:

hi guys, basically quick rundown is:
1. container1-->bitmap image with bitmapData.
2. container2-->bitmap image with bitmapdata.
3. im using the latest tweenmax
4. have correctly added a 2 seperate scrollrects to container1 and container2 that takes the width and height of the stage.
5. tweenmax is only moving the rectangles.
I get the effect i want, however, it still lags a choppy animation. Anyone know how come?

I'm trying to get an object to increase in size the lower it goes down the stage, and decrease in size the high it moves up the stage.
It only needs to increase or decrease by a small amount. Basically, it's for a game character. To ad realism to his movements, it would be nice to have this feature.
This is where i'm up to so far:
Code:
import fl.transitions.Tween;
import fl.transitions.TweenEvent;
import fl.transitions.easing.*;
[code]....
I think I need something like:
if (object moves up)
decrease
else if (object moves down)
increase

When a Flex component moves directly, so that its x and y properties change, then a "move" event is dispatched on the component. That's all fine.
However, a component may also move as a result of its parent component moving — or its parent moving, and so on. Now when a parent component moves, its children just "move along" without any properties changing or move events being dispatched on the children. Still, the children are moving on the screen. So how can you detect this kind of generalized movement?

I have a MovieClip instance which can be moved around the stage using startDrag() and stopDrag(). The instance also has some child MovieClips using addChild(). The parent moves the children when dragging, which is fine. The children have there own startDrag() and stopDrag() which should apply only to the child object, however it also moves the parent and other children. When clicking a child the MouseEvent of the child is being called but so is the parent.
public class Component extends MovieClip {
private var nodes_array:Array = new Array();
public function Component() {
x = 60;

I have a stage with a movie clip with the instance name of "mc". Currently I have a code that is suppose to move the player left and right, and when the left or right key is released, the "mc" slides a little bit. The problem I'm having is that making the "mc" move to the left works, but the exact some code used for the right doesn't.
[Code]...
I just don't get why when you press the left arrow its works completely fine, but when you press the right arrow it doesn't respond. It is literally the same code.
