ActionScript 3.0 :: Objects Class Find And Change Another Objects Xy Properties?
Oct 13, 2010
What I have is a game with a Level object, inside the Level is a Player object, and they don't have instance names given, what I'm trying to figure out is how to do is make it so that the player can change the x or y properties of the Level object.
To be more precise, I'm making it so that when the player moves in a certain direction, he either moves accross the stage, or he starts moving the Level object around the stage, it'd be in an Event kind of function, now I can easily make the Player move, but I don't know how to make the Level object move which the player is inside of.
I have a little bit of code that makes a nifty kaleidoscope effect, but I would like to take it one step further by having each star in the kaleidoscope gradually shift color as it expands outwards. Right now, I create randomly colored "star" movieclips by drawing 6 different triangles within the movieclip, and then add those individual "star" movieclips to a "stars" array.
What I'd like to do is use a "for...in" loop to grab the .color property of each of the "star" movieclips and change it slightly (using colorTransform?) at each ENTER_FRAME. How can I go in and access the star.color property (or is it star.transform.colorTransform?) of each of the movieclip objects that are now stored in my "stars" array?
Would it be:
Code: for (var i in stars){stars[i].transform.colorTransform = myColorTransform; }OR for (var i in stars){stars[i].star.transform.colorTransform = myColorTransform; }
I have created a class, that is simply a group of text fields. In the main app, I create instances of this class, and add them to the main app. How can i access the textFields that are in the class, to say, change the text, etc... When I try, I get this: 1119: Access of possibly undefined property txtHeadLine through a reference with static type Article.
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
How can you call objects based on properties they have instead of object names? For example if i want all the objects in an area to move somewhere else. Thats not what im trying to do but just an example. Also im using flash mx 2004
I'm studying the code for a vertical shooter game that is given in the book "ActionScript Design Patterns 3.0." The author is explaining the factory pattern and so covers just that aspect of the code -- doesn't cover hit testing. I would like to figure out how to do hit testing for this example because it's similar to something I am planning.
The code for the game consists of 12 classes, abstract and concrete creator classes, abstract and concrete product classes and a Main class. These classes instantiate the ship and weapon objects at various points in their execution. I made a separate Collision class and I'm trying to find all the objects on the stage using this Collision class so I can hit test them with each other. Here's my code:
Is there a way to fix this code so I can access objects on the stage? Am I missing a cast somewhere? Or do I need a different approach to find objects on the stage in a multiclass game?
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.
Previously I post a discussion on this matter on Flex Adobe forum and still don't understand what needs to be done. So, I'll try my luck again on stackoverflow. I'm using drag and drop data binding functionality in flash builder 4 on a data-grid. However, the data I need to show need to be query from another object.
i'm currently using a dictionary to associate a boolean to my (non-dynamic) sprites, but i would like to know if there is a smarter way of doing this? i could just use MovieClips to assign my properties instead of Sprites since MovieClips are dynamic, but i will not be using any of the MovieClip properties or functions so it comes down to a best practice issue. basically i want to create a state boolean property on my sprites - they are either on or off so my boolean variable is called isOn.
I am attempting to set the propreties of a navigation button (movie clip) that has been built dynamically. The button contains a text field that I want to format and a movie clip that I want to adjust the alpha. I find the object using getChildByName(), however do not seem to be able to set the properties using the code below.[code]
I'm trying to iterate through all the objects in the stage and I'm not sure how to do it. It's kind of improvised through my previous experience with C# and javascript. First I need the correct list/array with all the stages children. I need to check their type. I have a special custom class which extends Sprite with some additional properties only.
Someone proficient in actionscript 3.0 who can show the proper way to do? for(var obj:DisplayObject in DisplayObjectContainer) { if(typeof obj == "Pic") {
I am working on a native extension for Flash. I am going to invoke my native methods from Flash and pass Dictionary objects where those objects have various data members of various data types. These property types are dynamic and might not be known at compile time.So I found that we have a method called FREGetObjectProperty that says it can return the value given the property name. But in this case since we dont know the property name since it is dynamic, how to extract the property names and values from the Dictionary objects?

New to AS3, long time programmer. Essentially I am creating a myriad of objects, all of which will have the same functionality, although the properties will vary between each object, including the artwork. I believe they will all be movieclips as they will be interactive and I believe they will be moving.
I am wondering what the best way to create these objects are. I am assuming that I create an object class with the functionality and properties, I'm just unsure how to instantiate multiple copies with different properties, if that makes sense.
let's say you're passing an object to a function {title:"my title", data:"corresponding data"} how can I get the function to know what the names of the items/sub-objects are (title and data) without specifying them?
I'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.
I have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?
I have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")] [Bindable] private var _list:ArrayCollection;
I will try to give as much detail as I can. I am creating an CRM application using Flex(Cairngorm 2)/Java/Hibernate. The basic problem I am having is this: I have a Customer class in Java that has an ArrayList of Address classes. I have a Customer class in Flex that has an ArrayCollection of Address classes. When I make the remote object call for a Customer I get back a Customer object in Flex, but the ArrayCollecion objects have a data type of Object instead of Address. If I try to call for a List of Address classes I get the same result. If I try to call for a List of Customer classes I get a list of Customer classes in Flex. Using tomcat 6 with the following jars:
How do I align a movieclip, which width and height is user-defined, inside another object (this one is static, though). Top-left alignment is easy, x=0 and y=0, but what about center, center left, bottom left, etc? Math(.round) i suppose, but how?I want an object (static) inside the movieclip (user-defined) to stay aligned to, for instance, the top right corner, similiar to the minimize, maximize and close buttons at the top right of your browser.. The height and width data is pre-defined by the user in another file.But that does probably not make any difference...
I have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
Code: ... var videoPlayer = new VideoPlayer(...); addChild(videoPlayer); ...
And inside VideoPlayer class i have of course dozens of objects (movie clips, sprites representing different parts of VideoPlayer) and dozens of event listeners attached to them. My question is, if i want to remove this VideoPlayer class from my main class is it enough to just do:
I want to create a flash movie which firstly loads a selection of images/objects into a portion of the frame. After this is complete, the user can then drag these objects onto another area and the object will be created where the user has chosen. The user can then drag another instance of the ojects onto the area.
For example, there is a background of a lake in one area. A selection of boat pngs are loaded in an area below the lake. The user can drag these boats and place them on the lake. They can drag a boat multiple times if they wish.
I have two movie-clips, one is small-box and another is big-box .Both are rectangular shape. Small- box has an index 0, and big-box has an index 1. Their x,y are same and big-box being big in size gets hide small-box. Now the problem is the listener attached to small-box does not fire as big-box is on the top of small-box. what would be the way to get listener fired when click on small-box area??
Is this the correct, most efficient way to recycle objects when creating an array of objects?
package com { public class CreateList extends MovieClip { //this is the object I will be recycling private var newProperty:PropertyRow; //this is the array I will use to reference the objects
I have a class that represents a turret in the center of my screen.When I hold down SPACE, I want it to create a "bullet"-object that moves in the direction of the turrets cannon, every frame the SPACE key is held down. I am having problems with this cause I am getting this error when I am trying to create the object:
Error #1009: Cannot access a property or method of a null object reference.
This is where the error occurs:
ActionScript Code: public function chaingun(x_:int, y_:int, rot:int, cd:Number, spd:Number, sprd:Number, life:Number) { this.Cooldown = cd; this.Speed = spd;
[code]....
PS: What happens is that when I press the SPACE key, the "turret" class event handler runs the function "Shoot_Chaingun" and that function creates a new Chaingun-object (which actually is a bullet), that inherits the x, y, and rotation of the turret, along with some additional varaibles, including lifetime. Then upon creation, I use "addChild(this)" to add it to the main stage, and "removeChild(this)" once it's lifetime is up.
EDIT: And also, I just realized I don't have a MovieClip linked to this chaingun class. How do I make sure that every time a chaingun object is made, the MovieClip is also loaded?
