I have text field about in the center of my stage. When a button is clicked, I want this text to split and animate out and the new text to appear. What I thought was to use the Bitmap data object and draw the content movieclip using the .draw() method and then manipulate this pixel data. But I have only done very trivial things with pixel data in actions script.
View 2 RepliesIf I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;

View 1 RepliesHi, I am brand new to Flash and I come from other development environments so I have a question about a possibility. I am aware that you can have a symbol (like a MovieClip) use a custom class to handle how it responds to the world, but I was wondering if it's possible to be able to set some values via flash without having to touch code. For example, I create a MovieClip called Crate, which has a class that lets it be destroyed, but then the designer wants to specify that certain crates have contents inside of them. Is there any way to do that in flash without having to create a new class for the crate?
In other words: the designer puts a Crate in the world and then sets a propery (for example: contents = TennisBall) and the Crate class handles the rest. Will this work? Also, am I right to understand that instances of symbols are all the exact same? So I can't have the designer create a new instance of Crate and then change it to be a little different (like draw a sticker on the Crate), but still have it be the same as all the other Crates?
I hope these questions make sense and I apologize if I asked this in the wrong forum. I'm very interested in developing games for flash, especially after the news that CS5 will let you export to the iPhone, but I'd like to keep the code away from the designer as much as possible,
Is there any way to test if a display object has been added to the display list?
View 9 Repliescan I resize a display object (container) without its contents (children) are resized?
For example, in the following code when I resize the green square, red is also resized. I wanted to resize only the green.

var sprite:Sprite = new Sprite();
sprite.graphics.beginFill(0xff0000);

What's a simple way to detect if a display object is currently on the display list?
View 1 RepliesI have a flash slideshow with 2 divs overlaying it, one at the top and one at the bottom.[code]Both overlay properly in Firefox/Safari/Chrome, but nothing I try seems to make it work in IE. I'm using Remy Sharp's HTML 5 enabling script to make the HTML5 mark-up work in lower versions of IE.What's funny is that the second div, #intro overlays correctly, but #top-menu always appears behind the` slideshow.All 3 elements are absolutely positioned with z-indexes explicitly set. No matter how high or low I set them the flash object is always in front of the #top-menu element.I have checked the rendered <param> tags and one of them lists wmode as transparent.The flash object is dynamically inserted with php through a CMS, so I have no access to the <embed> tag that many have suggested adding the transparent attribute to.

I'm creating a Flash movie that loads some XML containing details of some text and a image URL, that needs to replace a existing MovieClip in a Flash movie. Is there a way in Flash to replace a existing MovieClip or to update it so that the updated/new display object keeps the original look of the original display object and any Tweening for the original display object still works we the new or updated display object.
Here is the code I'm using to load this:
import flash.events.IOErrorEvent;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.display.DisplayObject;

Can you make one Bitmap Object (I'm using an external jpg) or something similar, and then display it many times simultaneously without creating a separate object each time?
Also, would they be easily removed or hidden?
I've got a little checkmark jpg graphic loaded here, but I'm not sure how to go about using it in many places at once.. I can only display it in the one place at any one time...
I'm thinking there might be a way to load the picture once, then use its bitmapData elsewhere in new display objects somehow, without needing to reload the image over and over?
It's my understanding that a display object cannot be in the display list more that once.So if I add something to the stage shouldn't a second addition of the same object replace the first? for instance:
[code]...
there should now only be one "myDisplayObject" on the stage.
Can a flash.display bitmapData object be converted to flash.displayObject? i bump with an error when i tried to convert a bitmapData to DisplayObject
=> setChildIndex(DisplayObject(bitmapData),0);
"TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::BitmapData@35f4779 to flash.display.DisplayObject."
know if the index effect the scope of an object because I am creating a game and for some reason, I get an error like below
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.objects::Torret/updateObject()
at com.objects::EngineApi/loop()
[Code].....
updateObject is the loop for all my objects. I have one centralized loop and in that loop it calls on an array of objects that have been placed on the stage. all of them containing the method updateObject. to update the status of the object. addGameChild() is a encapsulated addChild() , that not only adds the object to the stage, but places it in a array so it's updateObject() method can be called on. it is also used to make it easier for garbage collection.
A display object container on the stage has some bitmap images of sizes 50x50 arranged in a order one by one. Now if i click on any of the thumbnail image (bitmap) the entire container should move and position itself so that, the bitmap image clicked is placed in the center of the stage.
View 1 RepliesI apologize in advance -- I am new to Flash. I am triyng to build a Flash object to display images from a catalog. I would like to build something like this. I really just need some advice/direction to get started.Once I know the basics/techniques to be used, I can go from there. Is this some thing that can be done solely in Flash or will I need to use some combination of Flash & Javascript. Right now, I am thinking I can use the loader class to achieve something like this.
View 1 RepliesgetChildByName('name') will work as long as that child is in the first frame.
View 3 RepliesI am using swfLoader to load external flash movies in my flex/actionscript code. If the loaded swf was made for the newer flash player versions (I believe 9.0 or more) it loads as a flash.display.MovieClip object which has methods for play/pause and go to frame. However if the loaded swf was made for older flash player (I believe 6.0) then it loads as flash.display.av1movie which doesn't have methods for play/pause. Is there a way I can play / pause the av1movie from my flex code.
View 2 RepliesI have camera input app in flash (AS3) and I draw some graphics over it. I want to take the image snapshot of the stage visible area but only the video an graphics I draw over video. I want to exclude controls from the image snapshot. My display object layout is in following relation:
-stage
--canvas (Sprite)
---video (Video)[code]..........
Stage size is fixed and I want to take a image snapshot of everything that is child of my canvas element (camera input video and overlayed graphics, but excluding controls). I am able to make this image snapshot when overlayed graphics are inside the bounds of stage size. I do it like this:
var bmpd:BitmapData = new BitmapData(canvas.width, canvas.height);
bmpd.draw(canvas, new Matrix(1, 0, 0, 1, canvas.x, canvas.y));
But this gives me unwanted result when graphics which I draw on top of video on canvas exceed the bounds of stage display area. How do I limit the image snapshot only in the bounds of visible area inside stage?
If an asset (say an swf) is already loaded. Does it increase memory use to add and object to the display list?
View 4 RepliesBase extends MovieClip document class extends Base how would Base properly access a display object which is already placed on stage in the flash ide? for example creating the var in Base's class definition = 1152: A conflict exists with inherited definition in name space public. but just referencing the var = 1120 undefined property , as the item is only a variable of the document class Is the only approach to let the classes load, then create the display object rather than have it on stage already?
View 6 RepliesI've been working on an FXG Editor, and I'm using the the senocular transform tool to move, rotate, scale and skew an object.
Is it possible to detect if the the Display object has been skewed just from inspecting the matrix of that DisplayObject? even if said object has been move, scaled and rotated as well.
I want to only serialize the matrix of an object to FXG if has been skewed and not if it has just been rotated, moved, or scaled.
In Actionscript 3 is there any way to determine the precise display object hierarchy an event will traverse through when dispatched from a given object? The object is not necessarily a display object.Although I could imagine this actually being useful somehow, in my particular case it is a learning exercise. I'm trying to master the event system in flash and have some locations where I'm very curious what path an event will take when I dispatch it.
View 2 RepliesWhat options exist for rendering markup in Actionscript? I am looking for something I can use to write templates for menus, tooltips, and other display/frontend stuff in a Flash application. I want to be able to load a template from a string, and then render it as a display object. The kinds of things that would go inside would include text, with possible font styles, text positioning, and images.
View 3 RepliesI'm about to start on a side-scrolling game which will involve around 10 different characters the play could choose from and probably about 20 different enemies. Each of these will have slightly different graphics, movement speeds, attack rates, etc. but I'm wondering how to manage it. The way I see it there's two options: Have a general classes "Player" and "Enemy" with a setter method for the exact character which could set a bunch of class variables like speed, max health, etc.. Most of the code would be the same but I'd need a lot of "if" statements in some places (ranged attack vs. sword, etc.).Have a whole bunch of classes "Goblin", "Scarecrow", "Skeleton", etc. that inherit from "Player" or "Enemy". All the stats could be hard coded in individual classes, no need to perform multiple checks on which character it is, but there will inevitably be some code repetition.
I'm bearing in mind that I'll have to reference these regularly. For example, each "Player" will probably have a "target" class variable to track who it's moving towards/attacking. If I strongly type this as "Enemy" and then set it to an instance of "Goblin", for example, will it be cast to "Enemy"? Is that a bad thing performance wise? What about using Vector.<Enemy> for tracking objects on screen? I'm guessing I'll have the same casting issue if the actual objects I push there are instances of Player's sub-classes. Will it negatively impact performance to have ~30 extra classes if I go with option 2?
If I have a variable
a = 456
how can I get the numbers from it like
a1 = 4
a2 = 5
a3 = 6
i have a var lets say 'x' x="i like cheese and want to eat it everyday" i want to split the var x by every 10'th character, assuming the 10 chracter is not in the middle of a word , then i want it to split it before that so that no words are not cut out...
ex:
x="i like cheese and want to eat it everyday"
arr[1]="i like " 7chars causs 10th char was inside 'cheese' and spliting of words is not allowed
arr[2]="cheese and " 10 chars exactly , splits at space
arr[3]="want to " 8 chars 10th char inside eat .. u get the idea by now i hope
arr[4]="eat it "
arr[5]="everyday"
so its splitting the variable every 10th character.. if the 10th chracter is a space, if it is not it backs up to the previous space and for the next array slot starts from there
I do a lot of work with GWT but don't have experience of Flex. I was talking to a guy today who was looking at moving some large Flex based applications to GWT due to the Flex application getting too big and using too much memory in the browser. This is a problem I have had before with GWT - browser apps using lots of memory as all the code gets loaded when it starts.
However, in GWT 2.0 there is now a code splitting feature to overcome the problem of the client code getting too big. This allows all the code (javascript) not to be loaded as one big file on start up but instead code split into different files that can be loaded when required.
I was thinking as to if there is anything similar in Flex. I assume the Flex application code all lives in one single SWF file which loads at start-up so this approach is not possible but thought there might be other solutions.
On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk at a time while showing a progress bar?
It sounds like JavaScript doesn't have any file manipulation abilities, but what about Flash and Java applets?
This would need to work in IE6+, Firefox and Chrome. Update: forgot to mention that (a) we are using Grails and (b) this needs to run over https.
I'm currently working on a little project of mine, where I have a character and a number of different items like clothing,hairstyles etc, which over time.. hopefully will grow into a tremendous amount.The thing is, if I have eveything in one fla file, there'll come a time where it becomes too bloated/large and Flash will eventually lag.So, is there anything way I can keep for example.. all the clothing in a separate fla/swf and the main character in another fla.But when I publish.. They all combine back together?I customise the character dynamically with references to linkage identifiers.. So I need a way which allows them to be split into different swfs, but still be able to call to the right clip.
