ActionScript 3.0 :: Change Alpha On Individual Element?
Oct 2, 2010
I am working on a project for school using ActionScript 3. I have a matrix created with an animated movie clip. The matrix looks like a bunch of shapes changing size and color on the screen. I would like to have it so when I move my mouse moves over an individual shape in the matrix the alpha will change to be more transparent... like 0.5. I'm sure it would be a mouse move function, but I don't know how to write that part of the code.[code]...

I have two buttons without names and I'm trying to have the same exact code on each so that you can click the button and it will turn white (or look like it), and click it again and it will turn back to blue (alpha at 100).This is the code I'm using on each button:
Code:
on (release){
if (_alpha == 100){
_alpha = 1;
[code]...
Unfortunately it causes both buttons to change their alpha to 0, not just the one that the code is on.Could anyone tell me why this is and how to make it so that only the button clicked is the one that has the alpha change? The reason I'm doing it this way is that I am going to end up using over 600 buttons like this, and I would much rather be able to copy and paste them in rows instead of naming them (I've already spent upwards of 45 minutes naming them A1, A2, B1, B2 and changing the code to fit).

I have a movie clip that holds a button (latter a dynamic textfield -- (button is quicker for testing )). I have the movie clip alpha set at .65 as I want the background image to bleed through slightly. I put the button on the movieclip as I want it to be visible as the movieclip tweens on stage. My question is, can I target the buttons alpha when the button is a part of my movie clip or does the movie clip and the button have to be seperate?

how to grab the transparency (or alpha value) of individual pixels in an embedded or loaded video? We tried copying over a frame of video into a bitmapdata object with transparency enabled. However, even though we can "see through" the video at certain spots (indicating alpha = 0 there), the alpha value comes back as 0xFF for every single pixel in the BitmapData object.Obviously alpha data is being stored inside the embedded video, but how can I actually get that value?

how to change the volume on individual sounds. I have the sounds linked from the library but when I use the setVolume command in actionscript, it lowers the volume on ALL the sounds and not just the sound I'm trying to target.

I have a Flex DataGrid where one individual cell needs to be rendered in a different way from others. Specifically, for one row of the grid, one of its cells should be hidden.
The DataGridColumn is set out like this in my .mxml file:
[Code]...
but that doesn't work - in fact it messes up the display in a rather entertaining fashion (one of the other cells in the row gets an extra checkbox.. I suspect it may be possible by using a custom ItemRenderer class but that seems like a lot of code overhead for a fairly simple case.

I've gotten as far as getting a listbox with a list of articles to display the articles in a dynamic text box, only i can only get it to work if i use one huge external text file that contains all the articles. what i want is to have each item on the list open up its own external text file, i.e. for each item on the list, there exists a separate text file. I'm about ready to put my fist through the monitor, and that would suck because this is a really nice monitor

I have a screen with a few components (textInput, textArea, checkBox). I want to check if there has been any changes to the components. Foe example if text has been entered or checkbox has been clicked. Is there a direct way to do this instead of checking value of each component and then setting a Boolean for this?

I have two boxes on the stage. These two boxes together are converted to graphic. Each of the box - lets called "A" consist of some kind of surrounding (the line around the box for which we set up[ stroke) which I will cal "B". And inside that box theres another box of different color - I will call it "C", with different surrounding - call it "D".
(It is inside the first one).The other box from that graphic looks the same, but has different names. "E","F","G",and"H" respectively. All of the elements "A","B","C",and "D" forms a button. I have some code to use it.(with event listeners) My question: If I would like to change the colour of the element "B" (which are a movie clip), how will I code it.
ActionScript Code:
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.utils.Timer;
var urlLoad:URLLoader=new URLLoader();
[Code] .....
And it tells me: Access of undefined property B...
The code works fine for whole button(A). A changes color, but I would like only the surrounding to change the color. I guess I have to put some path in there, but I am not really sure how to.

In my application, I allow the user to change the font of a text field. They use a combobox component to select the font. Can I change the font of each individual label in the combobox to match the font it is named? Like, Microsoft Word style.

I will do my best in explaining what is happening. I have a feeling it has something to do with how I declare things, but I am kinda new with AS3 so please have patience.
On my stage I have an movie clip (mContainer). In the library I have another movieclip (mElement), that has been exported for actionScript as mElement.

Right now I'm in the process of building a drum machine in Flash. The interface is based off of combo boxes and data that I load into the combo boxes. Depending on what you choose in the combo box, a sound should play at a certain interval. I have that part working perfectly. When you click the element of the combo box, the sound plays, and my set interval function calls.
Now the problem I am having is actually clearing the setInterval everytime you change the element in the combo box. I am using a listener set up to find when the combo box changes, I know it has something to do with when I clear the interval, but for the life of me I can't figure out how to clear it when the listener is called.
Here is the listener function I am using to call setInterval:
[Code]...
outside of the listener, and then took away the 'var', from in front of dbInt1 = setInterval..... and it works perfectly. It seems like a really weird way to do that though, and doesn't seem like it would be in good coding practice to do that.

Basically, I want to change the alpha value on my movieclip. I start my mc with an alpha of .08 (8%).
mc.alpha = .08;
What I then want to do is increment it to .9 (90%) and when it hits that, decrement it back to .08, and then when it hits that, increment it again to .9 etc.
I have tried
if(mc.alpha==.9){
mc.alpha -= .01;
}else{
mc.alpha += .01;
}

From what I understand you can change the alpha value of a textfield to be fully transparent. I would like to have chat output that fades after a while. I was wondering if there was a way to change just a portion of the string inside of a text field to transparent. The textColor does not have an alpha value. I could just use multiple text fields but I would like to avoid doing that if possible for efficiency sake.

Ok. I am new again so I hope I am describing this correctly. I don't know the best way to do this but this is what I've dreamed up so far: I have a number of movie clips on my screen, all thumbnail sized images, each with an instance name (ex: tw_lifeoftheparty, tw_xmen, tw_xfiles, tw_diehard, etc.).
In each movieclip there are 2 layers: the thumbnail image(bottom layer) and a black border(top layer). The black border is an object named wk_border and isin each of the thumbnail movieclips.
I have given wk_border the same instance name in each thumbnail movieclip "border"

Let me try to explain what I'm doing. I have multiple movieClips (mc_aitkin, mc_anoka, there will be a lot more) on the stage that I want to change their alpha using data from an xml when it loads. I can isolate the info I want and trace it so it shows in output, but I'm not sure how to use it from there.
I've tried to convert the xml data to a number and do an if/else as shown below, but the only output I get is "not" (from a trace). So I'm guessing the if/else isn't recognizing the xml data as a number?
If I can resolve that, the next step will be to apply this function to the large number of mc's I'll have on the stage. Would that be with something like e.currentTarget.alpha = .5; ?? I don't think I can put it in the same changeAlpha function because there the property of 'e' would be undefined.[code]...
