ActionScript 3.0 :: Find Out What Object My Mouse Is Over
May 13, 2010
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.
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.
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"); }
how to do an object move towards the mouse when i move the mouse the towards the object and backwards when i move the move away, something liike the menu on [URL]
ok how do you find out if the user is scrolling the mouse?? like you can tell where the user points there mouse, with a onRelease, is there like an on scroll also i am gonna start upa flash web site bussines thingy, any tips on how much i should charge for a web site? i might cahrge between 50dollars to 200 dollars depending on how tricky it is, is this good or bad?
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.
I've got a grid of sprites.Now I would like to drag an image on a grid-element.Therefore I need to know which x/y of the grid-element is the closest point to the mouse-position.
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'd like to animate a button when I put the mouse over it. I use mouse_over or roll_over events, ok. But what if I hide the button when I click it and then I show it again later without moving the mouse? The mouse stays over the button, but the button does not animate, as there is no out/over event: I have to move the mouse out and over again to see the animation.
How can I detect the mouse standing on a button without the out/over event?
I have been trying to find out what other objects are within an object (AS3 )and am unable to get it going.With AS2, I was abl to simply run "for in" loop to get all the information.
I have built a site in AS2 and would like to know the position of a ball so that I can move a sign to it always.The whole website is in AS2, but I think I have written an incomplete code below for AS3. I need it for AS2 because the whole site is in AS2. The get position of ball is wrong, but I just wanted to throw in some ideas eg.
Code:
// get position of ball ball_mc.addEventListener(<what goes here?>, ball_pos); function signMove(Event:MouseEvent):void{[code]..........
I have an array of objects, I separately have a reference to one of the objects in this array (in particular, the object dispatched an event and its reference is the event target, which is what I have). How do I find this object in the array and remove it from the array?
I didn't create that Timer... so this is problably a component I have addedUnfortunately it will be difficult to remove all compenents until if find the "one" ..Yes I should have notice the CPU usage sooner !and yes I will do that if I don't find another solutionI am of course using some components without having their sources...My questions :* How can I find the guilty component ?* I tried to find it using Kap Inspector without success ...any tips for Kap inspector ?
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)
get the target path of an object.So that i can give properties/methods to that object.Actually i need the target path when an event occurs.like on click/keyup/enterframe..and so on.
var curinstance:Object = ev.target.valueOf();
In the above code i get the instance name of the particular object i cant give properties and methods to it.
how do you find an object's index / position within an array in flash actionscript 3? I am trying to set a conditional up in a loop where, if an object's id is equal to the current_item variable, I can return its position within the array.
I have a couple of components on stage that I need to disable mouse events on. I've been looking through the documentation, and it looks like the components probably have a Mouse listener setup, and then they fire off their functions when their listeners are notified of an event. In order to remove a Mouse listener, I need to know the instance name of the listener object, is there a way of referencing this? I couldn't find it as a built-in function.
Maybe I'm off-base, and there's a better way to get a component to stop responding to mouse events. I tried
I have a horizontal slider which slides images. When one of the images is in the middle of the stage I want to be able to show text related to that image. At the minute it shows all the text but thats not right.
What Ive got is a way to find out if one image is hitting the middle point. [AS]trace("0 "+_imageHolder.getChildByName("0").hitTestPoint(39 0, 120)); trace("1 "+_imageHolder.getChildByName("1").hitTestPoint(39 0, 120));
Just getting started with ActionScript 3, which is, I'm told, an object-oriented langauge.Therefore I am trying to find the language's Document Object Model (DOM), but I cannot find it anywhere.This would be a comprehensive outline of all AS3 objects with their respective properties, methods, etc. Any real OOP language would have this.
This object is ok, and shows up correctly in debug mode. The problem is I have a country name i.e. private var _country:String = "Angola";, and I want to get the corresponding value 'AO' from the XML object. Do you know how to do this?
I have tried loads of Livedocs examples, but cant get it to work. P.S. I am working on a HtpService & WebService driven app to display global weather conditions overlayed on a Google Maps interface. Going to make it available to the Flex community when finished.
