ActionScript 3.0 :: Object Oriented Game - Referencing Dynamic Objects
Jun 26, 2009
I'm doing this object oriented game and I create a bunch of 'boxes' via a for loop
Code:
Select allfor (var z=0; z < numOfBoxes; z++){
var box:Object = new Object();
box.mc = new Box();
box.mc.name = "box"+z
box.mc.x = Math.round((Math.random()*(530-box.mc.width)) + 20);
for (var i=0; i<boxXArray.length; i++){
[Code] .....
I get my random amount of boxes scattered over my stage (I haven't put in any checks to see if they are touching). How do I 'name' these boxes so I can reference them later? Say I want to move the .x of boxA in another function? Is there a simple way to call them box+z instead of just all as box? (Then I can run them through a loop later to talk to them).
I'm a programmer familiar with object oriented programming, with experience in C++, C# and the MS Visual Studio development environment.
I've been tasked to create a web based game using Flash CS4 and ActionScript3. I am new to Flash, ActionScript and game programming. I have never used previous versions of Flash or ActionScript.
The game will be a single player role playing game. The player will have the ability to create an avatar. The player will move the avatar from screen to screen based on button clicks or drag and drop onto objects in the current screen. Players must register, and player information will be stored in a database backend. Additonal data will be saved to the backend database during game play.The saved data will be based on player actions in various screens, and in some cases data entered in a form on a screen.
For a first pass a stick figure avatar and screens containing simple buttons and simple objects to drag the avatar to will be sufficient. I would like to store data in a database tracking date/time information, e.g. date/time each screen is entered/exited.
ame_Manager.as= this manages the creation of balloons, players and collisionsBalloon.as= This is the balloon classPlayer.as=This is the player classThe Game Manager class will pass stage to the balloon and player classes and create them. I add these two in the Game Manager class.In the balloon class i add all the balloons in an balloon array.Now when i run the code i am unable to check for collisions as nothing happens when the player and balloon collides. and i get a child must be a caller of the display object when i ry to remove the balloons after they have crossed the stage.I have been trying to make it work for a long time a the game is very very simple.in the Object Oriented way of designing this simple game as i think that is where my error might be.I will post the code for these belowGame Manager.as
Code: public class GameManager extends MovieClip{ public var backGround:BackGround;
All I want to do is add text from my string to dynamic text field when I click dynamic buttons. What should the as code be for this? Here is my code. Right now I just have the click returning another shape.
Im finished with the essentials (I read and exercised AS3 Essentials from Moock) and now Im looking for a more advanced book/tutorial/guide/etc that covers deeply about AS3 game development.
does anybody know about any good open source xml framework for actionscript? I find the one that comes with actionscript is quite cumbersome and unintuitive so I was wondering if anyone there is a framework that loads xml files into objects in actionscript 2.0 if you know of any such framework
I'm new to the object oriented stuff and I'm trying to learn how it works. Here's what I've started on - it's led to a few dilemmas. I have one flash file and two .as each with one class. In the timeline of the fla file, it reads: ActionScript Code: var FileObject:ScriptFile = new ScriptFile(); function onEnterFrame(){ FileObject.CallInput(); }
Call input is a function in "ScriptFile.as" that calls another function in "Input.as"; ActionScript Code: class Input{ public function Input(){ } public function keyListener(target:Number):Number{ [Code] .....
In output, when I press Left, it will say -5 over and over again, and I'm trying to add to xpos value but that isn't happening.
I have no background in programming and at 49 it seems that I am having a hard time understanding AS3, especially AS3 OOP. I wonder if I should give up at this point. I have been studying AS3 for 3 months now. Here's what I don't get right now.:
Clearly i'm a coding Novice, and I am going absolutely insane trying to figure out The Object-Oriented Scrollbar. I have the caurina folder in the same directory as my .fla , but when I publish I get these three error messages:
1172: Definition caurina.transitions could not be found. 1172: Definition caurina.transitions could not be found. 1120: Access of undefined property Tweener.
When I change my publish settings to find the files I get this message: 5001: The name of package 'caurina.transitions' does not reflect the location of this file. Please change the package definition's name inside this file, or move the file. /Users/npenta/Documents/AKA::Truth/Web/caurina/transitions/Tweener.as
I have followed correctly the Object-Oriented Scrollbar: Part 1 [URL] and Part 2 [URL] tutorials and I seem to have a problem when I want to use it with code. I have in my library the following objects: ScrollBox:Linkage ScrollBox ; ScrollBar:Linkage ScrollBar ; Thumb ; Track ; Masker ; Long (the long content that I am displaying with a scrollBar)
I create a new scroll with this code: Select allvar scroll:ScrollBox = new ScrollBox(); for(var i:int = 0 ; i<= dictionarXML.length(); i++){ //This are some actions i have in my .fla (the DictionaryWord is a custom class) var word:DictionaryWord = new DictionaryWord(); word.engleza.text = dictionarXML.cuv[i].engleza; [Code] .....
Ive gone through the Object-Oriented Scrollbar tutorial on [URL]. Its working great and I have multiple buttons inside of the moveclip it lives within. The problem occurs when I create another one on the same page. I have put one on frame 1 and the other on frame 5 so that I can select a 'category' and the scrollbar movieclip changes to the relevant buttons.Ive duplicated the movie clips and changed the instances accordingly. I keep getting these errors in the Output panel when playing my swf;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::MainTimeline/frame1()and when I click the like to the second category it comes up with this error;TypeError: Error #1009: Cannot access a property or method of a null object reference. at as3_movieplayer_fla::scrollbox_1/thumbUp()Not really sure what im doing wrong - or even what these mean!Here is the code from my main actions layer;
I tried the tutorial on [URL] The Object-Oriented Scrollbar: Part 2 tutorial. Every thing is fine, but when I load the swf to main.swf
- I can scroll the scroller, but not the content - I got this error
TypeError: Error #1009: Cannot access a property or method of a null object reference. at com.leebrimelow.ui::ScrollBar() at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at com.leebrimelow.ui::ScrollBox() .....
The scenario is: - The main timeline play and stop at 56. - At 56 the main.swf loads the sec1.swf
I was following Lee Brimelow's Tutorial on making an object oriented scrollbar. I am trying to implement this with a project that im doing. So far im getting this Error.
1120: Access of undefined property masker_mc.
Here is the Code:
import caurina.transitions.*; var yOffset:Number; var yMin:Number = 0;
I am using an Apple PowerBook g4, Flash CS4, ActionScript 3 and I am trying to develop and design my own site and truth be told I have no idea what I am doing nor how I will put all the pieces together. But at the moment I am trying to make a horizontal scrollbar using the Object-Oriented Scrollbar: Part 1 tutorial. Basically all I have done is used x instead of y within the actionscript code. However, the only error I am getting is with the import caurina.transitions.Tweener*; code. What comes up in the compiler error report is:
Location) Symbol 'scrollbox' , Layer 'Actions', Frame 1, Line 1. Discription0 1086: Syntax error: expecting semicolon before mult. Source) import caurina.transitions.Tweener*;
The caurina file was downloaded the from Tweener Documentation and Language Reference site [URL] and I used the tweener_1_33_74_as3.zip Stable version 1.33.74, Actionscript 3 (Flash 9+) Featured Jun 2009 34.4 KB file. After placing the unzipped caurina folder into my project folder and that not working I have placed in Applications/Adobe Flash CS4/en/First Run/Classes as I read within the forum post "Re: Object-Oriented Scrollbar Part 1" posted by AKA//TRUTH on Wed Jan 20, 2010 12:30 pm.

I know there are a billion questions regarding what books are best and I'm sorry for posting another, but all of them see to have an orientation to a language I am not familiar with.
My problem is I learned to program before OO became big, then I stopped programming for a few years, moved into web design, moved into coldFusion, and now find myself in PHP, actionScript and FLEX.
I have muddled along for quite some time, but I am really struggling with my understanding of OO and would like a good book that will help me out with it. If that book is geared towards Flex and AS3 then that would be awesome, but if it had no language specified either I would be happy. I'm just not sure how reading a book oriented to Java or whatever is going to help my understanding of AS3.
Simply put, what I'm trying to do is create a Dynamic Textfield with custom scroll bars via this tutorial [URL], that renders an external HTML file with CSS attached as its content instead of images like in the tutorial. I've tried a mix and match combination, ultimately, when I test the movie, the scroll bar works, but I see no content to scroll through. I have attached my project file. prototype.fla [ 80 KiB | Viewed 730 times ]
I am dynamically creating a movieclip, say, a ball. I want to apply a movement to each new ball created. I have created a movement function and now I need to know how to use this function as a method on each newly created ball. Would I do something like this:
Any links to any tutorials that teach how to create a full site with Object Oriented Programming? I am one year in now on Flash and AS3 and think I am getting pretty good at the basic AS3 principles and creating dynamic sites. Now I want to start migrating over into OOP so that I can create the more dynamic and browser friendly Flash Sites, but OOP is much more complex and would like a good example or sample of how to finish a full site under OOP coding.
currently i making this game and objects would spawn at random and be able to click but when de game starts itself, the spawn is correct but i am unable to make it stop when time goes to 0seconds.
I have no experience with Object Oriented Programming, so I wonder about the following:
1) Will the code past the .LOAD line (in red) be executed only after the image completes loading? 2) Can I nest several listeners as seeing in my code below?
var xBoard:Number = Math.floor(mouseX/cellSize); var yBoard:Number = Math.floor(mouseY/cellSize); if (board[(yBoard-1)][xBoard] == 0) { root.getChildByName("b"+(yBoard-1)+xBoard).alpha = .7; }
I want to be able to call various movieclips I have arranged in a grid from these two variables (xBoard and yBoard). They get new values every time I click on my gameboard.
Basically I check if they space ahead of the unit is empty. If it is I want the alpha of that space to change designating you can move there. The movieclips are arranged in a grid and named b00 (top left) to b77(bottom right).
This is the error message:
1061: Call to a possibly undefined method getChildByName through a reference with static type flash.displayisplayObject.
If I take out the getChildByName... root.("b"+(yBoard-1)+xBoard).alpha = .7; This is the error message:
TypeError: Error #1123: Filter operator not supported on type Game_fla.MainTimeline. at Game_fla::MainTimeline/test()
Is it possible to control an object/element on a instance? If so, how is it done through actionscript?
There is an instance "instance140" off of the root, that has an element named img4 that i need to reference... does anyone know how I would go about that?
I've created a for loop to do the following:add instances of button MovieClip from library to stagename the instances via name propertyadd instance names to array for later referenceadd event listenershese 4 steps are working peachy, however, I'm having troubles referencing these instances later on through my code. I'm pretty sure that the problem is in my data types not matching, but I'm not sure how to fix it.
var menuBtn:mc_menuBtn;var menuBtnList:Array = new Array(); for(var b:int = 0; b < numFiles; b++){ //add instances to stage menuBtn = new mc_menuBtn(); testClip.addChild(menuBtn); //adding button instances to
I need to be able to dynamically position a component generated in Captivate 4 via ActionScript that in child SWF that is imported into the Captivate project. The problem is that I don't know how to reference the objects in the parent movie. I can set a label on the object and reference the parent itself with:
MovieClip(this.parent)
but this doesn't seem to work:
MovieClip(this.parent).label.y
And I suspect that it is because some how Captivate subclasses the objects but I'm having trouble finding out how the hierarchy is structured.
I have a simple function that dynamically creates text fields. My text field name is referenced by var thisTextField. Problem is, when I try to do things with my text field, actionscript shoots back an error as such: There is no property with the name 'text'. How am I supposed to apply properties to my object if my objects name is a variable?
Code: function showProducts() { var products:Number = 0; var thisTextField:String = "product" + products + "_txt"; for (var itemID in _global.rtsData[_global.rtsPos]["products"]) { [Code] .....
