ActionScript 3.0 :: Create A Class Where When Mouse Click On An Instance Of It?
Jul 5, 2010
I want to create a class where when you mouse click on an instance of it, all other instances are notified about this click.
I want this functionality to be inside the class so there wll be no need to write any code outside the class definition, like assigning listeners to all instances and such.I wrote the following code but the event I dispatch doesn't get catched.
package sample{ import flash.events.EventDispatcher; import flash.events.MouseEvent; import flash.display.MovieClip; import flash.events.Event; public class labels extends MovieClip { var dispatcher:EventDispatcher = new EventDispatcher(); public function labels() { this.buttonMode = true;
I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.
it might sound weird but what i need is... Create a movieclip, with an instance name, when i click with my mouse left button, anywhere i click! i don't even know if it's possible(Anyway if you wonder why i need this, i'll explain:in a certain level of my game, you play with a m�ssile launcher, and there's enemies in front of you, when you "fire" against them, (so, when you left click) your pointer (or mouse arrow) create's a movieclip that is an explosion, and, if this explosion hit's the enemies, they die
I write some working code that creates a circle on mouse click with a radius of 5 and with a random colour each time...I have the code to create the circle and the code for the random colour here:
var myColour:Number = Math.floor(Math.random()*0xFFFFFF); this.graphics.beginFill(myColour); this.graphics.drawCircle(0, 0, 10); this.graphics.endFill();
Essentially I want to create a Flash application that places random coloured circles with a radius of 5 on the stage with a centre location of the mouse position each time a user clicks.
I am trying to pass a variable to a method in one of my Classes so I can use it to create the correct movieClip (image).
My Class code looks like this: package { import flash.display.MovieClip; import flash.display.Sprite; public class SlideShow extends MovieClip{ public function SlideShow() { [Code] ....
I am getting the following error: SlideShow.as, Line 30 1046: Type was not found or was not a compile-time constant: Background.
I am learning JAVA, and of course I am naturally comparing it to AS3. I've noticed that JAVA classes have the ability to create instances of themselves:JAVA:
I am writing a code where I am trying to create a sprite variable in one class, and create several new instances of that sprite variable in another that all need to be on the stage at the same time. For example I created a variable like this, var ball:Sprite = new Sprite(), then drew the sprite in the same class that that variable was created in, then using encapsulation (i.e. _myNewInstance:AddNewInstance = new AddNewInstance(ball)) I am trying to reference that variable and create several new instances of it in the "AddNewInstanceClass" through for loops.
In as simple an example as I can think of, I have two classes: Dog and Cat. Both are subclasses of Animal, in this stupid example... I know how to create instances of both, however I don't know how to dynamically create them by name from a string. It would be something like...
There's another thing I don't fully understand in ActionScript 3 yet...
Let's say I have a class that takes care of certain things (KeyPress events, to be specific). But when I want to access the functions inside this class, do I have to create a new instance of it?[code]....
I have a number of GUI dialogs defined using MXML. Assuming these mxml objects have been compiled into my application, is there any way to instantiate these objects using ActionScript, sort of like this?[code]...
Is it possible to create an instance of a class without triggering the class' constructor?[code]In the case above, say I wanted to play around with a Foo instance, but I really don't want my global.foobarCount going up, nor do i want to pass in any value at all for bar.This could be useful for introspection where you want to learn more about or pass a particular class object but don't want to provide required arguments or trigger anything that the constructor may do.Is this at all possible? (Obviously, new Foo() just doesn't cut it here, since it would throw and arguments error, nor does just using Foo, since that's a reference to the class itself).
I'm working on a project right now in Flash Builder which is strictly AS3. I've written a bunch of code for various graphic assets that are being developed in the Flash IDE and compiled into a library swf. So, for example, I might have a drop down list Sprite which I layout in the flash IDE and then set its class to: [url].....With the library swf loaded into my project, if I need to create a new dropdown list I would say something like:
Code: load.getDefinition(classes[name]) as Class
and then create a new instance of the class that is returned. I decided to try saying 'new DropDown()' instead of pulling the class definition from the loader, and I got a new DropDown. I figure this is because the DropDown library asset is now in the ApplicationDomain and Flash Builder knows that when I say 'new DropDown()' I'm saying [url]....' and it can find that class file. However if my library asset just had a class of 'Widget' and no path back to an .as file it would throw an error. Am I correct in this statement?
When someone "click and holds" I want to fire off function over and over, say, once every 100ms while the mouse is clicked. Instead of MouseEvent.CLICK I would look for MouseEvent.MOUSE_DOWN and then start a timer on that event function that calls another function every 100ms. Then, on MouseEvent.MOUSE_UP I would stop the timer. Am I on the right track? Will I be able to get updated X and Y coordinates while the mousedown event is firing?
I trying to create a TextField in a Actionscript file, But when I try to create an instance of the class in flash no textfield is appearing. [code]...........
1. I create a board class in board.as as so, public class board extends Sprite { public function board(p1:Number = 0, p2:Number = 0, p3:Boolean = true) { this.mouseEnabled = true; addEventListener(MouseEvent.CLICK, go); } private function go(e:MouseEvent) { trace("mouse clicked"); }}
2. In .fla, I declare the document as an instance of the board class. 3. Clicking anywhere on the document's UI, no tracing output. 4. If I put a textfield as the child of board object (by adding these lines, var tf:textField = new textfield(); --- addChild(tf); In the constructor), I do see above trace() working. What am I missing? How can my board class receive mouse click?
I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')] public Class Base {
i'd like to create a single movieclip that responds to the same input (mouse click) in two different ways: if playhead is on frame labeled "one" go to frame labeled "two", otherwise if playhead is on frame labeled "two" go to frame labeled "one". i've tried if/else and switch statements with no success - what's a good approach to doing this?
It is possible to create a "virtual mouse" which will be click on links on the HTML page loaded into HTMLLoader? I tried to do this using the class senocular .url... but it does not work.[code]
I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
I have a class with constructor and overloaded methods in it. When i try to import that class using blazeds i get an error saying [RPC Fault faultString="Unable to create a new instance of type 'some class'." faultCode="Server.ResourceUnavailable" faultDetail="Types cannot be instantiated without a public, no arguments constructor."] How to import class having overloaded methods using blazeds
I'm creating a little game - The player controls a character that follows the mouse. Pigs run away from the player, and the player has to get them all into a pen. To make the game a little more difficult I'm trying to add an enemy - wolves, that attempt to perform a 'hunt' method every x seconds. This method sends a reference of the wolf instance to Main (my document class) and Main then loops through the pigs on stage to see if there's any nearby. Now as far as I know this works - my problem is I'm unsure how to send the pig instance reference back to the wolf that called the hunt method, so it can then 'target' the pig, and then attempt to pounce on it.
I'm new to AS3 and OOP in general and I'm trying to create a cursor class for a mouse avoider game, i.e a class whose position is mouseX, mouseY. This is where I'm at (the Avatar class in added to the stage in a Main class not shown):[code]But this doesn't work, I guess I have to refer to the mouse in some other way? I also tried using MouseEvent.MOUSE_MOVE which got me closer, but the avatar only moved when my mouse was directly at the center of the movieclip.
I have a custom class and inside its constructor, I need "x" and "y" arguments passed on. Now when I call the class and create and instance of it, flash should pop up "the code hinting"...(but it doesn't), or am I missing something???
I am trying to learn JavaScript and I am wondering whether JavaScript has a event listener just like ActionScript's ENTER_FRAME. Basically, I want this event listener to listen "all the time" not just wait for any particular instance (mouse click, keyboard event) of event.
It is possible to create a "virtual mouse" which will be click on links on the HTML page loaded into HTMLLoader? I tried to do this using the class [URL] - but it does not work I have something like this:
Quick question. I have been Googling this all morning, but it's either not there, or else written in a way that doesn't register. I am inclined to believe the latter, as this seems like it should be something completely trivial to me. I made a small Flash file using AS 3.0, and this is the first time I've really been able to stick to the OOP way of doing things and not hack together a mix of stuff from the timeline to get around not having everything work in the classes.
So I'd like to keep it that way, but one thing is eluding me: I can't call a method of an instance of another class (than the one I'm calling from) without resorting to "DocumentClass(root).instanceName.method." Intuition tells me there has to be a better way of doing this (like, without having to reference the document class every time I call another class instance's function; and CERTAINLY without having to use the word "root" - that just seems so Flash 5 to me. Does anybody have a better way of doing this that they can share?
