Alright, I've looked online at a bunch of different collision tutorials but they don't explain what I'm looking for. I want object A to hit object B and then execute a function via to a Event listener.
View 1 Repliesis it possible to determining what object calls a function based on an event listener? for example, i have 2 buttons on stage that call the same function when they are clicked. i'd like the function to determine which button was the sender.
[Code]...
When you click on the button something happens. However it seems redundant to me that in the declaration of myListenerFunction, the event object e of class MouseEvent, actually has to have its data type MouseEvent mentioned.
[Code]...
stage.addEventListener( MouseEvent.MOUSE_DOWN, clicSouris);
function clicSouris( pEvt:MouseEvent ):void { var positionX:Number=pEvt.stageX; var positionY:Number=pEvt.stageY;
[Code]....
what appens when I add an Event Listener to Object Event?
Following the logic with the display list in AS3, I thought only Classes who inherit flash.display.InteractiveObject could react from events coming from mouses (or keyboard).
I am developing a game with Flixel as a base, and part of what I need is a way to check for collisions along a line (a line from point A to point B, specifically). Best way to explain this is I have a laser beam shooting from one ship to another object (or to a point in space if nothing is overlapping the line). I want the line to reach only until it hits an object. How can I determine mathematically / programatically where along a line the line is running into an object?
I could try measuring the length of the line and checking points for collision until one does, but that seems like way too much overhead to do every frame when I'm sure there is a mathematical way to determine it.
Edit: Before checking an object for collision with the line itself, I would first eliminate any objects not within the line's bounding box - defined by the x of the left-most point, the y of the top-most point, the x of the right-most point, and the y of the bottom-most point. This will limit line-collision checks to a few objects.
Edit again: My question seems to still not be fully clear, sorry. Some of the solutions would probably work, but I'm looking for a simple, preferably mathematical solution. And when I say "rectangle" I mean one whose sides are locked to the x and y axis, not a rotatable rectangle. So a line is not a rectangle of width 0 unless it's at 90 or -90 degrees (assuming 0 degrees points to the right of the screen).
I have a movie clip being dynamically added to the stage via an AS3 linkage call:
gameOver_mc = new GameOver();
stage.addChild(gameOver_mc);
The movie loads as required.But when the movie has been added I want the user to be able to press spacebar and a function to run.So in the GameOver.as class I wrote the following:
Code:
package
{
import flash.ui.Keyboard;
[code]...
But as soon as the movie clip tries to load I get the error message: TypeError: Error #1009: Cannot access a property or method of a null object reference.I would have thought this would work fine. When I trace the statement in the Constructor function is works. Its only when I try to add an event listener that I get the problems. So am I not allowed to add event listeners from a dynamically loaded class?
I'm trying to add an event listener inside an object but it doesn't seem to work. other OO languages it makes sense for an object to be able to attach events etc itself rather than have some external action do it.Here's an example of what I'm trying to do:
ActionScript Code:
package {
import flash.display.MovieClip;
public class Player extends MovieClip {
[CODE]....
This gives an error "1120: Access of undefined property MouseEvent." suggesting that I don't have access to MouseEvent from within the instansiated object.What I can do is create an instance of the class from the Document Class for example and then do the following:
ActionScript Code:
newInstance.addEventListener(MouseEvent.CLICK, newInstance.mouseClick);
run event listener through dynamic object call

I have to develop an application in flex. In that application an user can draw line while dragging the mouse. Then if he clicks on that line it should be selected. How to add mouse click event listener to a line object?
View 3 RepliesI have four buttons named button1, button2, button3 and button4. I want the code to trace the name of the button when the button is clicked. This is just an eample of what I'm doing in my project. The project itself is too convoluted to put up and explain. My problem that needs to be solved is, how do I refer to the button in the Function?
var c:int;
var buttonName:String;
for (c = 1;c < 5;c++) {
buttonNum = "button"+c;
[Code]....
When I say "trace(this)", the code doesn't know what "this" is because I've taken this[buttonNum] out of the loop by having to put it in a Function. How do I call to the object that is in the listener that called the Function?
Ok I have this 100% width/height Flash embedded and when the user moves the mouse I want to display a panel, which disappears after x seconds if there is no more mouse movement.
I think I need an addEventListener, but I am not sure MOUSE_MOVE is the correct one. When the mouse stops moving I need to start x seconds to hide the panel, so I think with a timer?
[Code]...
is it possible to write a function to move an object and then call that function on a clip event for instance
function (bounce){
script;
script;
}
and then call it by saying
on(mouseOver){
this.bounce;
}
I'm listening for a Loader to COMPLETE loading, and then I jump to a handler function "thumbLoaded". I would like to create a new Loader obj. each time I enter the "thumbLoaded" function. I would like this new Loader to be equal to the Loader that triggered the COMPLETE event. But I don't know the correct syntax to refer to that Loader. I'm trying to refer to the "parent" of the contentLoaderInfo object (ie, the Loader object itself). I've tried both "target.parent" and "currentTarget.parent". I get an error that says "parent is not a valid property of the loaderInfo object".
ActionScript Code:
function loadThumb():void{
if (i < kitchensGallery_xml.kitchen.length()){
var thumbLoader:Loader = new Loader();

If I run add('movie123'). How do I get the string 'movie123' in the enter_frame_handler function? UPDATE This forum post (Click Here) describes the issues I am having but doesn't provide the solution I am looking for. Luckily @kapep provided a simple solution that solved the issue.
I am having a weird problem with scope/reference. I am using a loop to preload a number of thumbs in one go, I am creating a different listener for each one on the fly and then passing event handlers for each one of them. This should not be difficult using a loop, but somehow I cannot access the the parent object on my listener and therefore I can't do much with my thumbs after they are loaded.Here is the relevant segment of my code. myThumb_mc is a temporary variable that does not exist when the loop finishes, you can copy and paste this code to test it though. It should work to that extent. (you'll need an image1.jpg to be in the same directory)
Code:
var myThumb_mc = _root.createEmptyMovieClip("myThumb_mc", _root.getNextHighestDepth());
myThumb_mc.clipLoader = new MovieClipLoader();
myThumb_mc.clipLoader.loadClip("image1.jpg",myThumb_mc);[code].....
The code above works, but it does not look nice and it cannot be the right way of doing this. Long question short, how can I access the parent of a listener from a listener object? ._parent does not work.
I've begun development on a isometric game, and have what I thought to be the hard part out of the way - the map generation from external files, screen-to-isometric conversions, etc. However I'm getting stumped on the "easy" stuff.Basically what I'm trying to do is this. Create a function that will add an object to the map (stage), then add an eventlistener so when it's clicked on, it gets added to the player's inventory. Lets take this sample code:
Code:
public function addObjectToWorld(o:IsoObject):void {
// ...code to add it to the world

When I use MouseEvent.MOUSE_OUT the target is [object MovieClip], but when I use MouseEvent.ROLL_OUT I get [object Bildspel] - and Bildspel is my class. The thing is that when I use ROLL_OUT I'm not able to delete the targets ENTER_FRAME event.

I want to listen for a custom event dispatched from the document class in a custom subclass. For example, let's say in the document class I have:
ActionScript Code:[code]....
So that the subclass will trace 'Event from document class received' when the 'customEvent' event from the document class is listened by the eventlistener. However, the output is only 'customEvent dispatched', meaning it wasn't heard in the subclass.
I'm moving on to my next massive programming project and I'm trying to decide whether I should code it in as 2.0 or 3.0. I came across the new click event model in 3.0. Right now it's looking like a pain in the butt to me. So now I have to make a function and add it as an event listener? what the hell? What's the benefit? I understand stuff like this makes AS a more complete language but it's kinda annoying.
View 1 RepliesI am having an issue with a class I'm working on. I currently load an image as a bitmap and store its data into regState:BitmapData so that I may make new instances of that image later on. When I test if I can use the loaded data at a later time with my newBitmapIntance() function, it says that regState is null. I'm lost as to why this is the case, since it works flawlessly to create an instance of itself in my loadContent() function.
Class so far For reference:

import flash.display.MovieClip;

I want to make a static function that I can use in all the custom classes.It should be some kill(); function that would remove the object from the stage as well as removing its event listeners. I made it in Document class, and it didn't work. Here's the code:

public static function kill(e:DisplayObject)

I'm trying to create a boundary for a player object, controlled with arrow keys, in my game using the main stage's height and width. For example, one test point is at the top edge of the player object's bounding box so that when the player object's head touches the stage's top edge, the player can't move anymore to the north. The player object is manually instantiated to the center of the stage by using the Flash stage editor so it will start at the center before the program starts.The problem is that right at the start of the program, I can no longer move the player object up or down with the arrow keys but I can still move it left or right. The intention is to allow the player to move north until the player object's head touches the top edge of the main stage.[code]
View 1 RepliesHow can I create an xml object (or any object in fact) named after a variable, i.e variable called section with value "names" create object [section value + "XML"] = new xml(); result: empty xml object called namesXML
View 3 RepliesI have an object which is assigned a number of properties:
var project_array:Array = [];
var slideObject:Object = {
project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
Iv been having some real trouble lately attempting to create an object panorama, emphasis on the object version, iv found plenty of tutorials on how to do regular panoramas (ie, from one spot looking outwards, i want to make one of something looking inwards orbiting it) iv used flash quite loosely before in the past and have come to the conclusion from various articles on the internet it is capable and probably the best way to make a small file size.
basically what i wanted was to have it so that when u click and drag side to side it would show around the object, im not too worried about how fast around it goes or if it accelerates the further away from the centre its dragged, just the main control im looking for. at the moment i have 180 odd pictures of my model im looking to orbit, or less or more depending on what people think is better (its a 3d render i made so i can choose how many pictures it has) or iv already got it stitched together into a video.
the ideas id already had were that it would load each picture into an empty movie clip based on the frame number, ie it would load model001.jpg on frame 1, model020.jpg on frame 20 etc etc, but that didnt work as i suspected and it seems to flicker which i probably should expect as it has to load each picture each time. my other idea was that if its possible to make a movie scrubber, and load the video of the orbiting object in, then just use a scrubber to control moving it around but i couldnt find anything (that wasnt to buy) on how to do that.
I am creating an actionscript video player in Haxe and to avoid the asyncError I am trying to create a custom Object. How do I do this is Haxe? The client property specifies the object on which callback methods are invoked. The default object is the NetStream object being created. If you set the client property to another object, callback methods will be invoked on that other object. Here is my code.
public function new()
{
super();

View 2 RepliesI've been starting to create my own classes for a project and I've encountered an error that I don't know how to solve. This is for a Game class collection.
How do I create an object with ActionScript if I only know the name of it? I have a class that should add an object as a "grid" and place it accordingly, so if I have a Square box that I want to place by 4x4 on the screen it calculates it automatically. Well, that's the goal anyway.
I have a function in my Grid class, Add_Background that accepts an Object to be added as the grid background. I use a movieclip (don't know if I can use a graphic element).
I call the function myGrid.add_background("name_of_my_movieclip") or myGrid.add_background(new name_of_my_movieclip());
The first one I don't know how to use, I don't know how the syntax for creating an object this way (etc: grid[a][b] = new name_of_my_movieclip() doesn't work...) so there has to be some other kind of way on how to pass this to the function and that it knows what to do with it.
The other thing I've tried is passing the object to the function (new Grid_Background() etc) but I can't clone the object anyway I try it and the ActionScript reference site says there's an mx.utils.ObjectUtil that I can use for this, but I have no access to it that I know of (tried it).
