ActionScript 3.0 :: Defining Target When Typecasting Mouse Events?
Jul 30, 2009
Is it possible to define the target of a MouseOver event being sent to a method if it is being triggered by code and not an actual mouse event? By typecasting a string as a mouse event the receiving function is sent an acceptable value required by it to run. It will then go about executing it's tasks but if it has references to the target property an error is thrown because only the event type was sent to the function and none of it's properties.
ActionScript Code:
private function myFunction(event:MouseEvent):void {
trace(event.target.name);
} myFunction(new MouseEvent("mouseOver"));
Resulting error:
Error #1009: Cannot access a property or method of a null object reference.
Is there a way to send the target information along with the event when triggering a method in this way?
i am trying to do a simple blackboard on mouse down, start drawing on mouse move, if drawing, draw line on mouse up, stop drawing i set the listeners on a simple clip with a rectangle. if i dont fill the rectangle, the mouse events wont fall into the rectangle, but if i fill the rectangle, it will paint behind the rectangle, so anyway i wont see any succesfull results. what i did was create another sprite and paint within it; something like
Right now all the sounds (78 of them) on my guitar play using the roll_over event but that doesn't give the user much control over what sound is played.
The actionscript im using to play my sounds is this;
Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?
I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?
By the way am using actionscript3 to implement the app.
I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).
In a project i'm doing I have a custom cursor, using the start drag command and mouse.hide. the issue being that the movieclip being dragged is blocking the mouse from initiation mouse events properly.
I have a movie clip I am using as a button (instance name btn1) and I added an event listener to it (using the following line): btn1.addEventListener(MouseEvent.MOUSE_OVER, animate1); the function "animate1" triggers some small animation when the mouse is over the movieclip. my problem is that the animation is triggered both on mouse over and mouse out events.
It has been awhile since I have worked in flash.Right now I am working on something where I would like a panel to disappear when someone mouses off the stage.stage.addEventListener(Event.MOUSE_LEAVE, leaveHandler); It usually works fine but if I move my mouse really fast it doesn't fire. I have also tried the same thing using a custom invisible button that surounds the perimeter of the stage and I have tried ROLL_OVER and MOUSE_OVERand again, if I do it too fast my event doesn't fire (I am using trace)I can't find anything on the net about this - is this typical of flash that if you move your mouse too fast you break it? Do I need to increase my frame rate (I would really rather not because I have perfectly timed animations - I am at 30 frames per second)
I have a menu drawer at the edge of the screen that shows when the user rolls the mouse over it, but if the user overshoots it an moves the cursor slightly outside the browser window this is unfortunenatly registered as a mouse out.
I want to stop this by using event.MOUSE_LEAVE, but i need to use it as a condition not to triger a "leaveHandler".
I am looking to provide some UI functionality using the mouse- I have two distinct UI events to be achieved via mouse
a) change value b) delete object
I don't seem to have sufficient mouseclick events for both. I am avoiding using the right click as it has some default options(whose signing off will affect the whole project- not just this). I have mouse click used for change value- how do I use the doubleclick as the single-click events seems to get invoked prior?
Is it possible to get the target/origin of errors and error events when using UncaughtErrorEvent.UNCAUGHT_ERROR ?
I am logging runtime errors of users using a complex flash app and would like to know where things are failing. The target of the UncaughtErrorEvent is tracing as LoaderInfo (which is, I assume, because it is also kicking out the UncaughtErrorEvent) and the target of the ErrorEvent is null.
I have numerous objects, many of them are stored within other objects (and overlap in physical space). As I zoom into an object, it begins to fade away. At the moment it begins to fade, I load in the child object (or create a child object if one doesn't exist). I want to turn off the parent object's ability to respond to most events. The exception is the scroll wheel, which needs to be sent to both objects simultaneously so that the parent can continue to fade out as I zoom farther in. Try as I might, I can't find a way to tell Flex "hey, for right now dispatch these types of events ONLY to this object." I either end up with event dispatch stack overflows from trying to manually redirect the events, or I get events that don't activate at the correct time or on the correct object. What can I do?
how to manage the target of a mouse event. As everyone knows, if I use localX/Y property on a mouse event, I'll get the x/y coordinate of the curson referred to the target Sprite. But if I need these coordinate referred to another Sprite, layed in the bottom of the stage (therefore unreachable for the event), how can I do for these?
I'm having trouble retrieving a name from my mouse event target, so that I can tell which target was clicked.I have two buttons, forwardArrow and backArrow. The listeners on each arrow point to the same listener function in which I want to differentiate between which button was just pressed.I can't get any name but the class from event.target.What's the best way to differentiate between these?[code]
I used to play around with flash during the early days of action script 1.but now i can't seem to find my way around it. Used to be able to add the script to the button itself.[code]what I want to do is to have a toggle button show and hidethe objects on the movie.
I'm successfully using MouseEvent.MOUSE_OVER, but I need to know which one to use for when the end-user mouse away from the button. I've tried MOUSE_UP and MOUSE_OUT, but neither worked. Where can we find info resources that explain each one in details?
How to get general id (or) name from xml loaded images. bcoz, i want to drag and drop that images in generic method. Now, i currently used the event.target.name for each one.[code]
I am trying to create a game that has a weapon and a target for the mouse. Example in my attachment. I know how to make the buy button but how can I switch out for other weapon choices.
I've been going through some tutorials and samples of "drag and drop" flash movies and I always come upon the same bug. The drop target gets "stuck" to the mouse, and when I click the target it just drops down and doesn't return to its orig. position. This mostly happens when the target in the "lower order" is dropped behind a target that is "in front of it" Now I have used the [code]...
I'm trying to modify a mouse trailer I've found somewhere else so that it only reacts within a specific area on the flash page - say an area 780x549 on a 1024x700 flash file.Here is the code I am starting with - The file is written in AS2 for Flash 8+
//mouseTrailer i=0 onMouseMove = function () { var cur_x = _xmouse;
I had uploaded jpeg file onto the stage using File->Import.Now, how to access the mouse-events using AS3.0. i.e., when we click with mouse on the stage it should display the x and y co-ordinates of the point being clicked.These x and y coordinates must be displayed in text-boxes provided down on the same stage.
I've just hit a really strange bug with a program I'm creating. The program allows the user to add shapes (currently all squares: SmallThing, MediumThing and LargeThing) to an area of the screen, then drag them about by clicking and draging using the mouse. Pretty simple. Unfortunately, the code seems to be failing for the smaller shapes (they're not THAT small, currently the smallest shape is 32 x 32) which are not generating mouse events at all. I have used trace statements to verify this. I am having a few issues with the larger shapes ocassionally not registering mouse up events, but I can live with this - the main issue is with the small shapes not being moveable.
All the shapes are descended from the same super class, and have the same event listeners added to them when they are created.
Here are the relevant functions in my Screen class. It's all pretty basic code so I really can't see what the problem is.
i have a question about the mouse down / mouse move events in Flash. I've developed a small intreractive that requires mouse co-ordinates to be captured when the mouse is down and when the mouse is moved anywhere on the screen. It was working fine like this until recently when I checked my interactive in Safari and it no longer recieves mouse co-ordinate information when the mouse cursor leaves the Flash interactive stage area.However, it still works fine in Firefox. Is there anything I can do to get this functionality back when using it in Safari?
I have another problem with my scroll pane. I now have a bunch of Loader objects that are used to display thumbnail images in a scrollpane. I want to add a MouseEvent.ROLL_OVER event so that when I a person rolls over an image there will be some buttons displayed, IE a remove button so the user can delete an image from the gallery. However my ROLL_OVER and ROLL_OUT events are firing like CRAZY when I place my mouse over a picture. Right now I have the roll over and roll out events set to just hide the image (so I know that it's working). But all that happens is the image flashes....
