View 12 RepliesI'm building a project that has a character navigate through a room by clicking on the floor. Right now, the walls, character, and floor are all children of the same display object for sorting purposes. My question: is there a way to disable mouse clicks to the walls and character while allowing clicks to the floor? Using mouseChildren appears to be an all or nothing deal and I can't seem to isolate individual floor/wall/character objects for use with mouseEnabled.
View 4 RepliesI need a function that retrieves the average hexadecimal color values of a group of pixels in a square. Like a 4x4 area, and I want to be able to calculate what the average color is by retrieving the color of each pixel.
View 4 RepliesI'm currently making a color picker (pretty standard one, pretty much the same as photoshop with less options at the moment: still in early stage). Here's the picture of the actual thing : [URL] The problem is : to retrieve the color of the pixel that is under the color selector (the small one, the other is the mouse), I have this line that I thought would do it :
_currentColor = Convert.hsbToHex(new HSB(0,
((_colorSelector.x + _colorSelector.width/2)*100)/_largeur,
((_colorSelector.y + _colorSelector.height/2)*100)/_hauteur
));
Just to clarify the code, I simply use the coordinates of the selector in order to create a new HSB Color (saturation is represented on the X axis and brightness (value) on the Y axis of such a color picker). I then convert this HSB Color to Hexadecimal and assign it to a property. The hue is always set to 0 at the moment but this is irrelevant as I only work with pure red to test. It partially does what I wanted, but the returned color values are inversed for most of the corners:

i was trying to do in the above subject title... I have now decided to create a project using AS3 and would again be in any of your debts if you can guide me towards a similar code / function to the following:
var nTimeoutId:Number;var nTimeTolerance:Number = 6000;
import mx.utils.Delegate;
_root.onMouseDown = Delegate.create(this, setUserActivityTimeout);setUserActivityTimeout();

I have a "large" movie clip and "small" movie inside a "large" movie clip but on it's let's say upper right corner:
Code:
largeMc.addChild(smallMc);[
If i try to catch Mouse.DOWN events on them the following way:
Code:
largeMc.addEventListener(MouseEvent.MOUSE_DOWN, largeClicked);
smallMc.addEventListener(MouseEvent.MOUSE_DOWN, smallClicked);
Then of course both event are captured no matter where i click.Is it possible to capture independent mouse clicks on both of these two movie clips and if so, how can i do that?

Grab the color of a vector item at a specific pixel without converting it to a bitmap object and then using getPixel?
View 8 RepliesIs there a way to retrieve the color of a generic pixel on the screen using the mouse pointer inside the Stage of Flash Player? With the getPixel method of the BitmapData class you can get the color of a pixel only if the mouse is over a bitmap image, but what if I need the color a generic pixel on the screen?
View 4 RepliesSay I have drawn a triangle with[code]...
When the user clicks a point inside the triangle, we will get the x and y coordinates, do some calculation with those values and get some (lots) of pixel coordiantes accordingly (all of those calculated points will be within the triangle). And finally, change the color of those points (something different than triangleShape fill color).
for example,graphics is an object from a movieclip ojbect.I want to get the pixel color at the x,y location in the movieclip.How to do?
View 5 RepliesI have a spinning sphere, built using the away3D engine, it is wrapped in a bitmap. I need to be able to check the color value of the pixels in the sphere, however BitmapData only plots the 2D image, not the 3D sphere. So, the values become wrong. If I try to apply it to the sphere I get nasty errors. I have literally been stuck on this for days.

var imageMap:ImageSnapshot= ImageSnapshot.captureImage(object);
var pixelValue:uint = imageMap.bitmapData.getPixel(x, y);
I have a bitmap with many colors on it. When the user clicks each color needs to trigger a different method. However, I have no idea how to check the color value of the selected bitmap. I can create a new sprite and check the value of that fine through bitmapdata.getpixel() but when I need to actually check the actual bitmap I cannot get it to work.

I am trying to get a movie to update it's color after the user clicks on a button and changes the value of Red Green Blue.
How do I set it so that it keeps checking and changes it's color once the button has been clicked.
this is what I have on my movie.
Code:
onEnterFrame = function() {
my_color = new Color(this.window1);
my_color.setTransform(_root.myColorTransform);}
URL...when you enter the yellow zone, there is a zoom in and a zoom out when you leave, When you click the button you go back through the zoom out action. Everything is working as planned.However, if you go on the extended menu, then click on the edge of the button, you will enter a loop action of opening, closing opening, closing.I have identified the problem, but i am unable to fix it.In the Menuidle, the yellow zone have:on (rollOver) {gotoAndPlay ("Menuzoomin", 1);}Which is the one the script require to detect the enter of the mouse in the zone when you come from the outside this script is also the one causing problem because when you click on the edge of the button in the Menuopen, the button itself is zoomed - 40 %,thus reducing his detection box by 40 % too. This cause your mouse to "enter" the yellow circle and cause the Menuidle script to kick's in and want to open it.and because you are on the edge of the button, you get a loop.
You can also notice the mouse cursor switching back and forth.Is there a way to prevent that ? someway to tell Flash to not play the script in the yellow zone until the mouse is competly out of the zone ? not just the button itself but the whole yellow zone, Then refresh the script if the viewer return on the yellow zone so we start to zoom again.Or even to move the mouse 100 pixel on the left or the right ?I even tryed reducing or enlarging the hit zone of the button itself, it dont do anything.
When mouse is moved quickly cant get all the pixels it passed through.Actually i am working on a whiteboard application and i am writing by drawing circles in mouse move,when i use line draw curves are not smooth ie y using circles
View 1 RepliesI have a very simple question (in fact I've done it before, but forgotten). What code do you use to get flash to do something when you click and release the mouse button anywhere on the stage?
View 4 Repliesi have some movie clips on the stage and the background of these movie clips are, of course, the stage. now, i need to detect a click on any area of the background(the stage) to do something to the movieclips above it.What I did is, I laid a movieclip which has the same size as the stage, above the Stage and below the other movieclips. I then set this movieclip to visible = false. Next, I thought I could use onMouseDown to get the clicks but unfortunately, it isn't working because onMouseDown detects the click on anywhere I click.I am not using onPress because I don't want to have the hand cursor appearing on the entire flash movie.
View 2 RepliesI'm building a system that will record a user's experience in Flash (where they click and at what time it was). Is it possible to simulate a click? I would use this to replay the user's experience. If not, I guess I'll have to record what button object they clicked on and pass everything through the event handler.

The idea is that you click on the tank to select it (a new listener is added) and then you click again elsewhere on the screen to tell the tank to move/shoot whatever (the new listener is acted upon). However what actually happens is that when you select the tank, the listener for "handleOrder" is added but is then also immediately executed..!? How, why, what the f.
What is the best way to delay user mouse clicks?

I really don't know half of what I'm doing when it comes to Action Script 3. Through a lot of trial and error, I finally have my menu with submenus displaying properly, but just not functioning the way that I have intended. The submenu items appear when a mouse over registers on the mainmenu item. The submenu mouse rollovers are registering correctly because the right content is displayed and the alpha channel changes are registering. The problem is with the mouse clicks for the submenu items. I don't understand why but a mouse click on a submenu button is registering as a click on the mainmenu item, not the submenu item. Could someone please explain to me why the rollover function is working and not the mouse click, and what I need to do to fix my code? I hate to admit it, but I am really clueless here.And here is the relevant part of my code:
SWFAddress.addEventListener(SWFAddressEvent.CHANGE, SWFAddress_changed);
menu1.alpha = 0.5;
menu1.buttonMode = true;
