Actionscript 3.0 :: Determining Which Mc Is On Stage And Positioning It?
May 19, 2011
I have a series of movieclips acting as buttons that load different flashvars video srcs onto the stage.When the swf loads --- the first button is added to the stage after a 20 sec Timer completes.As you click through each button, the one just CLICKED is removed and a new button is added in its place.All the buttons are set to dynamically be centered on the stage. However, the function that is positioning them is called BEFORE the first button is on stage, throwing the error (Error #2007: Parameter child must be non-null.)here is the code inside of the windowResize method which positions the buttons.
Code: Select allprivate function onWindowResize(e:Event):void
{
//position hidden buttons[code].....
Even though I've set up a boolean var and set it to true after the first button has been added to the stage -- the method still tries to find the first button and gives me a error saying that it must be non-null.Basically I want to make sure that it doesn't try and position the first button before it has been added to the stage. I'm not sure if encapsulating this method inside of another Timer is a good idea.
The REMOVED_FROM_STAGE event is fired before the object is actually removed from the stage. I'm looking for a performant way to know when the object is finally removed.
I have a graphical component and I am trying to obtain it's coordinates relative to the stage by using the localToGlobal or contentToGlobal methods.
My problem is when scrolling a Container, these methods do not return the correct values, but return the old unshifted coordinates of the graphical component. Later, after everything seems stable, when trying to use the methods they return correct value so this means at the time where I use them after scrolling not all information necessary in computing have been commited.
For the case of the Container class I have investigated and although it passes through the scrollChildren method, the computation is wrong.For the case of the Tree component when scrolling with the wheel, the methods return correct value, but when pressing the arrow button of the scroll-bar the methods return incorrect value.
Until now I have tried to listen the scroll and the update complete events when they are dispatched but without any success. So my problem is that after scrolling I would need to know a moment(event to be listened or something else) that I can call the methods and the output to be ok.I would like the final solution to be uniform.
I'm trying to make some mcs be displayed from alpha 0 to 100, one by one in the stage and in random positions. I've managed to make appear it randomly from alpha 0 to 100 with this code:
I'm trying to make some mcs appear to alpha 0 to 100, one at one in the stage and in random positions. I've managed to make appear it randomly from alpha 0 to 100 with this code:[code]The strange thing is that only some mcs are positioned randomly and others stay in the same position, but not always the same.
I have a bottom bar on a site that has he following code: nav_menu.menu_bars._y = 0; But I want it to be at the top of the stage. Sorry for such a noob question, but how do it? I've tried nav_menu.menu_bars._y = -600; but when the browser is resized it obviously moves down the page. Is there a bit of code to keep it at top of the stage?
coordinates in flash, particularly after resizing the flash player window.I have an mc on stage and draw an ellipse inside that mc. The movie is of size 800 x 600.
Code: var ellipse:Shape = new Shape(); ellipse.graphics.beginFill(0x6CCDF4, 0.5); ellipse.graphics.lineStyle(4,0x186B87);
[code]....
If I check the coordinates of that ellipse from it's transform property, I see that the top left is at 400, 300.
This seems fine to me as this position is in relation to the stage, yes? If I convert this to a position local to the container I get values ~0,0.
Code: var stagePoint:Point = new Point(ellipse.transform.pixelBounds.topLeft.x, ellipse.transform.pixelBounds.topLeft.y); var localPoint:Point = join.canvas.globalToLocal(stagePoint);
When the flash player window is resized, the coordinates change entirely. Instead of being at 400,300 the transform property indicates that it is at 640, 510. I assume this is because the viewport has changed, but the stageWidth and width properties of the stage do not change.
i am loading 3 flv files so that the first file plays once and the other two loop afterwards. Now i am interested is it possible to position the flv files on the stage to certain coordinates when they start to play (so for example that the first flv plays as default in the centre, the second flv file plays a little bit right and the third plays a little bit left). This is the code i'm using:
I have a xml slideshow that is working fine. The problem I am having is all of the images load in at x=0 and y=0. I would like to have the images load at a specific x coodinate and y coordinate on the stage. I have been looking at other code examples to see how to fit this in to mine but I keep breaking it.
I have a group of 6 buttons which on my stage sit in the center and are 20 pixels from the bottom, I am trying to create a bit of a liquid layout, and the browser is going to be able to resized by the user. I want always for the buttons to stay at the bottom in the center of the browser 20 pixels from the bottom no matter wether it is resized too
I have multiple nested movieclip in its own different movieclip, and i would like to arrange them accordingly. My idea was to use the localToGlobal function. I can get the position of the MC on stage, but how do I use the function and place the MC based on stage?
cAPos = new Point(objectA.y); newcAPos = objectA.localToGlobal(cAPos); cBPos = new Point(objectB.y); newcBPos = objectB.localToGlobal(cBPos); objectB.y=objectA.y+objectA.height <-- based on stage
so i am giving these objects random x and y coordinates on the stage, but i need each object to be spaced apart from each other (lets say 20px) how can i achieve this. I have got the following code:
ActionScript Code: for(var i:int=0;i<=bubbleNumber;i++){ var bubble:Bubble = new Bubble();
im trying to achieve a Full Browser Flash and i want my bgimage to remain in the centre of the stage whilst other objects move round it depending on mouse movements but how would i go about centering the bgimage through AS?
Determining the value of a bit in a byte? Hence at a current position?It's something with bitwise but im not entirely getting it. I know how preset a uint's value (a 32 bit's value)Just not....able to take part of a bit (say the 3rd, 4th, 5th, and 6th position of byte A into a new byte(byte B))etter example:001101000101110100101110101011101000Let's say that's a 32 bit segment.
i know there is a code that determines which of two values is larger and returns the larger value.i cannot seem to find it in the actionscript help.i know you can do it with
[code]...
but there is an easier way and i cannot find the file that i used it in previuosly.
I have a container_mc that loads in a external MovieClip, lets call it video1.swf using the MovieClipLoader class (it actually contains a video of a 180sx drifting but thats neither here or there). What I'm trying to figure out, is a way to find out when this externally loaded clip terminates, then preload and then display another clip, called video2.swf. I call my preloader and load my external clips into the MCL class using a version I learnt in Senoculars preloader tutorials here [URL]
i have 3 variables and im executing a block of code depending which on has the highestow do i determine has the highest and the execute the code which ever has the highest
I have an swf loaded into my main swf. So far I can get a button in the loaded swf, to link to a frame in my main swf. However, how can I let my main swf know when the loaded swf has finished playing?Here is my code so far:
Code:
stop(); var imageRequest:URLRequest = new URLRequest("dylanTalking1.swf"); var imageLoader:Loader = new Loader();
normally the sound.length property is only accessibleafter the sound has finished downloading.I have heard there is an algorithm that can determine thesound.length property before an mp3 has finished downloading, or atleast approximate it very closely
Within my fla file I have an intro and I have added anaddEventListener on the skipBtn located within the intro and I getand error message. The button appears on the second frame and is onthe stage until the intro concludes. I have a preloader on thefirst frame. I get the following error message: TypeError: Error #1009: Cannot access a property or method ofa null object reference. at intro_fla::MainTimeline/frame2()This is the error when I debug the movie:Attemping to launch and connect to Player using URLC:Bteferraintro2.swf[SWF] C:Bteferraintro2.swf - 331059 bytes afterdecompression
I'm current building a game in as3; the proplem I have right now is when I roll the virtual dice, the player(marker) moves accross the board but what I need to know is: is there a way to find the instance name of the object(box) that the player lands on?

I'm working on a new website it's going to show a room & I think it would be kinda cool if this room had a window in in that outside showed the current local weather and portrayed day/night. I can make a script to check the weather on yahoo but I cant find a way of finding out the users location. It does't need to be exact, even just having the country will do.
i have to create something that loads text dynamically and then you can input words and it determines if that word is in that dynamically loaded text. I have to output a statement for three different reasons.
1. If the word is not found 2. If the word is found 3. If the word is found, but it's not the same (Ex. You enter hello but the word in the text is Hello)
I have it all working for the moment using functions etc....but the one thing I am unsure about is how to determine whether the character is uppercase or lowercase or maybe there is another possible way so that I can print out the 3rd reason from about.(telling the difference from hello and Hello.)
The whole thing is based off a tutorial I found here: [URL]
just got rid of the find next button and added an output msg box.
...How do you do this? I'm gunning for <65 kb and need to figure out if my published swf will meet this goal. Is there a window or something (maybe a 3rd party tool) to let me know what the initial download size of my swf is?
I'm trying to solve what seems to be pretty basic task. However, I was unable to find a solution. how can I determine if the mouse is already over a certain object? The this.addEventListener(MouseEvent.MOUSE_OVER, onOver); doesn't work because it will fire only what the mouse moves over from not being over. I'm trying to be able to tell if the mouse is over even without moving mouse, something like "this.isMouseOver()". Is it possible with some generic command without comparing the coordinates of the mouse and the object?
- I have an array of ~200 buttons. - Each button pulls individual info from a file online:
/routes/801/ /routes/802/ /routes/803/ ...- My pseudocode looks something like this:
Code: var myURLReq:URLRequest = new URLRequest("/routes/"+butNum); var myURLLoader:URLLoader = new URLLoader(); myURLLoader.addEventListener(Event.COMPLETE, infoLoaded);
[Code]....
My problem is this: Let's say the user clicks 5 buttons. Since data doesn't load immediately, I can't assume infoLoaded is being called in the same sequence in which the user clicks the buttons, but I need to know which file just loaded. Is there a property I can get from ev:Event so it'll give me the URL I used to load myURLLoader?
