Actionscript 3 :: Find The Color Under The Mouse?
Dec 23, 2009
grab colors using the 'draw' function of a BitmapData object. But these are somewhat limiting, I'm trying to implement an eyedropper-type utility and need to be able to know what color the user is seeing at a certain pixel.
I've tried using draw() on the stage, but that doesn't include anything that's a child of the stage. Next, it occurred to me that I could just look at the children of the stage to find the foremost one that's under the mouse, and draw() that, but then we suddenly get into a possibly time consuming recursive search. The simplest/fastest/best way to find what color is being displayed under the mouse in Actionscript 3.

In this tutorial : [URL]...it is said about something for color effect in properties pane. I can see the property pane but I can't find Color Effect. I'm using Flash Professional CS5.5. P.S.- This was my first Flash Tutorial (and that's really first one.)

In another scripting language I have used for other purposes (AutoIt Script) there was a function called pixelSearch where you could find pixel locations based on a color. What I would like to do is develop a SWF that "reads" the colors of an image and applies a sparkle effect to the areas that are deemed bright enough (close enough to #ffffff). Ultimately, it would be really cool if I could make it figure out how large the bright area was to make a larger sparkle effect (increase size of sparkle MC) or that if it was too bright, it would assume it was background and not use the effect in that location.
This effect would be used to load various thumbnails from a database and render them in the browser, each with the same SWF but different image parameters, to make the images sparkle appropriately.

I have a list of 98 countries. I have a world map that I have animated by storing all the movieClip names in an array. Below the world map I have the country names listed out in a few text boxes. I know I can turn these names into movieClips and then change their color that way. But I was wondering if there was a way for ActionScript 3 to "read" my paragraph and find the text name then change its color?

Is there any way to find out at any time if the mouse button is down?
I have some code that runs while the mouse button is down, but if I switch away from the Flash client while the mouse button is down, then the mouse up listeners are never called, so I'd like to account for this situation by checking if the mouse button is still down.
Ideally, I'd like something like:
if (Mouse.isDown) {
trace("down");
} else {
trace("up");
}

imagine i have a scene with hundreds of interactive objects, but they're all invisible, and i don't really know where they are. bad scenario, but work with me here.a while ago i saw a block of code that would trace() the name of every single DisplayObject within the entire scene when you rolled over it.. it was only like 3 lines of code - and it would affect all objects, even objects inside of other movieclips, etc.

I created a movie where I have a circle in the middle and a line drawing from the center out when the mouse moves. I want to calculate the distance from the mouse position to the middle of the circle. What I am going to do is have a sound playing from the center of the ball..The closer you get the louder the sound gets and the further away from the middle the quieter it gets. You can download my fla to see what I have so far.

Is it possible (if so how) to find out what word the cursor/mouse is over when it is moving over a < mx:Text > component?So for example as the user moves the mouse along a sentence (inside text component), each word will highlight as they go (I know you can highlight while pressing the mouse button down - but that not how I wish to do it).

I have prepared a simplified test case for my question. It will run instantly in your Flash Builder if you put the 2 files below into a project.I'm trying to display a List of strings and a confirmation checkbox in a popup:In the real application I dispatch a custom event with the string selected in the list, but in the test code below I just call trace(str);My problem: if I use click event, then the window closes, even if I click at a scrollbar (the !str check below doesn'twhen an item had been selected in previous use). And if I use change event, then the window doesn't close, when I click on the same item as the last time.riting a custom item renderer and having a click event handler for each item seems to be overkill for this case, because I have strings in the list.Test.mxml: (please click myBtn few times - to see my problems with click and change)
<?xml version="1.0" encoding="utf-8"?>

I am new to actionscripting and wanted to know how I can create a button that when I mouse over it the color changes from say blue to red. Except that it doesn't just change color it would change color as if it was in a motiontween, gradually from blue to red, instead of just changing color.

I think I'm really close to getting my multiple choice question to work! Here's what it does:
1) Read my question, possible answers, and correct answer key from XML.
2) Print the question, 4 answers, and 4 radio buttons on the stage.
3) Clicking the submit button on the stage, checks the answer. The user gets feedback based on whether they are right or wrong.
1) When the user mouses over an answer, I want to change the text color.
Currently, only the color of the last answer is changing colors, and it's changing colors if I mouse over any of the answers.
Here's my code:
Code:
import fl.controls.RadioButton;
import fl.controls.RadioButtonGroup;
var qLoader:URLLoader = new URLLoader();

I have followed Ned's code from another post, whereby if a text button is clicked, the color will change. The code is like
var clicked:Boolean = false;
var clicked2:Boolean = false;
btn1.addEventListener(MouseEvent.CLICK, btn1click);
[Code]....
Now if I click on the first button, it changes color and stays like that, which is perfect. If I click on btn2, this changes color and stays like it. The problem is that if btn2 is pressed, it should change color and stay like it (as it is doing), but btn1 should return back to its normal color (black).

It fades in correctly when you mouse over but when you mouse out it turns to a black color when it should be turning blue. Not sure why.

I have 30 buttons called thumb01 to thumb30. I have created this functions so when hover over and hover out of the one of the buttons it changes colour. I would like to use this for all my 30 buttons, but I dont want ot write the same code 30 times. Is there a way to for example to use wildcards so I can write thumbxx and address all the buttons.
var col:Color = new Color();
col.setTint(0xFFFFFF, 0.5);
set1_mc.thumb01_btn.addEventListener(MouseEvent.MOUSE_OVER,hoverOver);
function hooverOver(event:MouseEvent):void {
set1_mc.thumb01_btn.transform.colorTransform = col;
} set1_mc.thumb01_btn.addEventListener(MouseEvent.MOUSE_OUT,hoverOut);
function hooverOut(event:MouseEvent):void {
set1_mc.thumb01_btn.transform.colorTransform= new ColorTransform()
}
