ActionScript 3.0 :: Bitmap Data Instance Against Array Of Stored Object - Comparison
Jul 31, 2009
I'm looking for a good method to compare a single bitmap data instance against an array of stored bitmap data objects. I need to figure out how I can compare and arrive at the conclusion that the result either means that the images are of the same object/aka similar or if they are two totally different images. I tried checking threshold of the result of the compare() function but my efforts have failed so far.
Code: var enemyArrayOneA:Array = new Array(); for (var i = 1; i <= 84; i++) { /*
[code]...
I try to use race("mc.main1.a_0" + i + ".x = " + enemyArrayOne[i].x); and it doesn't work...I'm trying to find out if I can store instance names of movie clips inside an array and retrieve the movie clip's x and y positions.
I was wondering... i thought this might be a dumb question to ask but ive been wondering if it is possible to remove all the data that was inserted into an array?
i.e.
ActionScript Code: var loadAllThumbnails:Array = new Array("poop1", "poop2", "poop3", "poop4", "poop5"); someBtn.onRelease = function(){ //clears/emptys the array when released }
I am working on a project in which I am suppose to matain an array of movieclips, and I can also convert the movieclips into bitmap data. so I would like to know which one is the best to use either maintaing movieclip array or bitmap data array.
I am curious if this is an okay implementation of the Array.filter() method.
[Code]...
I was not able to figure out an implementation of the callback function for the filter() method, where the callback was outside of the getGallery() function. I wonder if there is a way to get the isGallery function outside of the getGallery scope?
Pattern_Array (created by a random function that pulls from Words_Array and stores the index)Now I want to create another array called Choices_Array that will compare Pattern_ Array to Words_Array and not repeat any of the Pattern_Array index's in the new array.
I have two custom as3 classes, TriviaGame and TriviaQuestion, and I am attempting to retrieve a bitmap image stored in TriviaQuestion and have found it impossible thus far.I am attaching the full AS files/SWF/etc in a zip file, but here are the parts I believe are important.[code]The only time I am able to access the bitmap's info (in order to add it to the display) is inside ImageLoaded().
How to do level adjustments (like Photoshop levels) on a bitmapData Object using the paletteMap method. I am fine with syntax and all that, just don't understand how the channel array values are used well enough to come up with them for myself. I have read to use a palette of 0 and 1, but I am not sure what that means. The goal of this is to take a grayscale image and get sharper black and white values for it. Also, I hope to understand how to use this method better in general.
How can I obtain the position of a instance whose name is stored in an variable? If there is a instance whose name I don't know, but the instance's name is store in an variable x. How can I obtain its position?
I'm creating a dynamic movieclip and the name/instance name is stored in a variable. How can I reference the instance if its stored in a variable?This is what I'm using and it doesnt seem to work (for obvious reasons). I know in php that you do this "blah blah" . $variable.
Does creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
I'm cutting my teeth in actionscript 3 on a game that has a character running through a world. So, I have set up my Hit Testing by using the bitmap data hit test method, since I figured my world is going to be destructible - it'd be nice to update the level and then redraw it and have the character interact with the new change. (That works beautifully) I am however; a bit confused as to how I have my hit Testing set up. I've been messing around with it, and it works for now - but I'm not sure why.. currently, I have a character set up by using a class I built and using a series of animations I created. So, this character has a walking and falling animation, etc. This is a movie clip.
Then there's a bitmap 'emptyBitmap' with bitmap data created - however; I never really added this as a child to the character. This is sized to the dimensions of my character. My level is created as a movielip, then it's drawn to a bitmap - when the level movieclip is changed, the bitmap redraws, and that's how this updates.
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap; var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
I'm using the following array to storing multiple variables for similar movieclips: public var ballPlaced:Array = new Array(false, false, false); ....however, its not storing the boolean value properly in the array? I'm using the following code in the ZoneFill and ZoneEmpty to assign it a value of true or false, e.g;
I have a "back button" scheme that includes using an array to store references to functions.However, when i have to troubleshoot something like this, one of the things i'd like to be able to trace is the names of the functions that are in the array. If i trace a for loop through the array i just get [type Function] for each function. I would like to look at it's name.Right now, im using a workaround that places objects with a func property and a funcName property, which is a string that needs to be indicated manually.
I am new to Flash and ActionScript platform. Presently, I am using ActionScript 3.0.I know only basics of Flash but not in depth. My issue starts here: For example, In Windows Operating System, Paint-brush uses Clipboard for temporary storage. My question is: Does Flash have Cache(i.e., buffer for temporary storage)? If Flash has Cache, then where does the temporary data gets stored, in what form, is the data accessible or atleast viewable?
First time on here.We teach English through games. All done on flash AS3 now. Want to put courses online so I have been told to use php to communicate to server and database. My question is:Do I use mysql to save stats or xml FIRST: I will get info from xml and send it to my activities in flash - I'm OK with thisSECOND: I want to send out stats from flash to mysql OR xml. The stats are:1. Student logs on of course using username and password (well that comes in not out)2. What lesson the student is on ie: 2, 3, etc...3. Highscores for game activities4. Scores student gets on each activity As far as I can see the only stats that grow are the scores on each activity and even those could be erased periodically.
Im having a bit of trouble integrating dynamic variables pulled from a databse using an ASP script with a flash movie.
Background:
I need to send variables stored in a ms sql db to a flash movie to display several values.
The dyanmic element comes in because i am using an ID to select the values from the db e.g id1 = joe bloggs id2 = paul smith
etc
When i am hardcoding the id in the asp script the variables are sent to the flash movie no probs and they display correctly.
I am also printing the asp code on the page and that all displaying fine.
HOWEVER, the issue arises when i make the asp code dynamic and by that i mean I am using request.querystring to pull the id
from the URL - The print out of the asp code is still displaying the correct variables, BUT they are not being passed to the
flash movie at all - the placeholder is blank there isn't event an error!!.
Couple of things to note -
- if you change the id bit of the url in the dynamic script to the printed asp code changes
- THE FLASH MOVIE IS IDENTIAL in both scenarios
- all variable names have remained the same
- it is NOT a location of file issue as we have tested the dynamic code files In another folder and no joy
- we are not using any other file includes or asp code in any of the page - all other code has been stripped out
THE ISSUE WE HAVE IS THAT THE PRINTED VARIABLES ARE NOT BEING PASSED TO THE FLASH MOBIE in scenario 2 where the asp code is looking for the participant id dynamically (i.e from the URL)
i'm trying to perform simple automated test on my Adobe Air Application. I decide to store some test data in external MS Excel file to decrease hardcode quantity. But I discovered, that this is not a trivial task, when you're working with Adobe Air.
Actually, i need to correct initialize an excelApp object, the rest part of logger is already implemented. I tried the following approach, but I can't find a package with ActiveXObject class defined.
excelApp = new ActiveXObject("Excel.Application");
Once a button is clicked in a submenu called SelectChar(a menu class extending my menu base class), it dispatches a custom event carrying an array of variables. This event is then listened for in the main Document Class called Engine, where the value of the passed variable can be used. For testing purposes im only passing 1 arguement in the array.
my Error when trying to trace the passed variable in isolation "trace(e.arg[0]);": 1119: Access of possibly undefined property arg through a reference with static type flash.events:Event.
Okay, i hope that made sense... heres the relevent code:
custom event class: passCharEvent.as
Code: Select allpackage com.asgamer.snipergame { import flash.events.Event; public class passCharEvent extends Event
ActionScript Code: public function drawPiece(xPos:Number, yPos:Number):void{ _piece_mc.graphics.lineStyle(1,0x000000);
[Code]....
The object is there. When tracing out the array for specific index it provides: [object Piece].
Or would it just be best to use a single dimensional array? End goal is to have a board class to be able to use for checkers and then potentially chess.
I have a movieclip that i want to move to 4 predetermined spots with a click of a button. I've been trying to put it together all morning. Is this a job or a loop?[code]...
