ActionScript 3.0 :: Memory - Use Copypixel To Copy A Region From This Tile Map
Oct 25, 2009
I am going to start using copypixel and I wonder if I am understanding the concept well. I am having doubts about memory use. This is my question: If I have an external image (tile map) I loaded , each time I use copypixel to copy a region from this tile map, I am using additional memory or only the map is located in memory? In my application I need to copy a bitmap region from a tile map to a variable (var 1) and then copy another region from this var 1 to a second one (var 2). My concern is to increase the use of memory.

I have been trawling around forums for hours now and the only was to save information LOCALLY in Flash seems to be using the SharedObject stuff. which is fine. BUT I am making a project which is meant to be entirely run from a memory stick i.e. portable. So, I was thinking it would be good to save the information from the flash to a SharedObject .sol file and then to copy the .sol file to the memory stick, then load the information back into the flash file from the copy of the .sol file on the memory stick!
Dont know if this is possible, but I need to some how save information created in the flash file stored on a memory stick (which will be text and possibly an image which would be loaded from the users pc) to a file on the memory stick and then next time the flash file is run, load all of the information back in!
I know all this stuff is possibly using PHP etc. but as I am running it from a memory stick on a pc which probable wont have internet access.

I'm making a game where you place tiles on a grid. When placing a tile, I need to check the existance of another tile to the left, right, or above and below, otherwise the tile should not be placed.. Here is a function I thought would work, that accepts one variable (the position of the tile just as it is about to be placed) :-
private function checkSurroundingTiles(gridPosition:uint) { var t1 = gridPosition - 12; var t2 = gridPosition - 1; var t3 = gridPosition + 1; var t4 = gridPosition + 12; for(i = 0; i < gridRefArray.length; i++) { var checkTile = gridRefArray[i]; if(checkTile == t1) { return true;

I'm trying to use copypixel to copy an image and paste it onto an existing bitmap. However, the image I'm trying to copy has transparent pixels so when CopyPixel's pastes the image onto my existing bitmap, the pixels already on the image is replaced by the transparent pixels from my image.
How can I make it so CopyPixel will only paste all pixels besides the transparent ones onto my bitmap?

I was wondering if it would be possible to use copyPixel to create a simple text printer for example you have a font as an image like this
[URL] then have some code that will transform your text ="hello world" into HELLO WORLD on your flash screen, but written in that font.
Because the font is spaced equally you could have the source x and y, times by 16pixels for each letter and move the Y source down 16 pixels when it reaches the right side of the image

My game moves small pieces slowly. I am trying to bitmap blit with either CopyPixels() or Draw() but because the end result always blits to a whole pixel value, the animation looks choppy. Have a look at my test swf where I use a small helicopter, which shows 60fps with very choppy movement. I thought the bitmapData's draw() method would allow me to smooth, but it apparently only smooths changes made by it's matrix argument. My only other resort is to go back to using movieClips with hundreds of frames that represent the various poses.

A web channel streaming service streams to a certain IP range, it only checks the IP in example.com/cmd.php?id=xxx (channel number) and outputs an rtmpe stream URL, nothing else.How do I trick it to get my local URL instead of the one on their server? I have considered squid proxy, but is there some way to do it with a firefox plugin or greasemonkey script?
Edit:I will try to specify:It's a streaming service from an ISP and cable provider. They stream for free to people on their IP's. On their webtv page, which is called webtv.example.com, there is a flash player. If you are not on an IP from their ISP, you can't stream anything but the test channel.When you try to change channel via. javescript:videoplayer_changechannel(xxx) it makes this HTTP request:
[URL]
If you are on one of their IP's you will get an RTMP URL, like this:
[URL]
This is what the flash player requests, and if it get's this response it load the channel requested. There is no HTML on the php page, just the URL. Note that the rtmp URL is static.If you are not on one of their IP's it will return a random sentence (something stupid, the programmers having fun).I wan't to trick the flash player into getting the right value, even though it's not on one of the ISP's IP's.

I have an FPS monitor running and notice that I am getting choppiness here and there, bringing my game from 40 to 27 fps and back and forth at certain stages. I have an idea of where it is happening, but do not know for sure. I looked up quite a few memory monitors but haven't found anything decent yet. Is there a memory monitor that allows you to see the memory leaked and find its location? If not, how about just he memory leaked?

I really enjoy flashing (I just do it for fun) but I'm very slow (read:dumb) when it comes to scripting.
Currently I want to create a site where in a region (the green textblock) your cursor disappears, gets replaced by an ecliptic mask and instead of the normal textblock, you see another textblock (red in the picture above) with hopefully hilarious changes to the original text with said mask when I'm done. When you move outside of the textblock(picture, whatever) to hit the link at the end of the page, your mousecursor reverts to the one you always have and is not hidden and replaced by the mask anymore.
I got the two textblocks done, it works fine. But for the life of me i don't know how to code that the mouse cursor is ONLY hidden in the region where the text is and not everywhere.
My script looks like this so far:
_root.maskee.setMask(_root.glass.masker);startDrag (glass, true);
Mouse.hide();

Just started coding in AS3 with FlashDevelop and coming from a C# background, I would like to know if there's something equivalent to the #region directive in AS3? The #region directive in C# essentially allows an IDE e.g Visual Studio to collapse or expand a section of code to improve readability. With #region directives, you can split codes in sections e.g constructors, properties, public/private methods to aid others perusing your code.

I'm designing a Flash Ad that requires a specific clickTAG.
ActionScript Code:
//
this.onMouseDown = function() {
var fo:LoadVars = new LoadVars();
fo.send(_root.clickTAG, "_top", "POST");
}
I want to implement user initiated sound, but I can't seem to define a certain region for the clickTAG. Also I'm using AS 2.0 I know the clickTAG won't take me to the proper location, but I uploaded it to my website to test the audio.[URL]I've attached 3 images or you can just go to my website and see it (click the link above).I tried placing an invisible movie clip over the location I want the clickTAG to work and attached the ActionScript to the mc.When I scroll over the audio button it changes, but when I click it, instead of playing the audio it just tries to go to the URL.I also tried using a button, but that didn't work either.

I need an event to fire when the mouse enters a certain area. There will be two of these areas on each side of an image that will be changing every couple of seconds (so both hover regions will be changing with it). (They will make a button appear to advance or go back an image.)I'm sure there are a few ways to do it, but what is the best way to get this to happen?I could try a mouse listener for the whole thing and test if it's within the coordinates but that seems gross...

So I've been working on a Character class for platformer/ generic side-view style games. The problem is that i might need bits of characters to appear to go through other characters (i.e. char 1 grabs char 2 and runs char 2 through with weapon) the problem with this is that the characters' parts are contained in movieclips to run code on them holding them together and keeping me from having to position them just perfectly every frame in the IDE. it seems I have four choices:
1) Completely reprogram the display list -not practical
2) just hide the area of the movieclip that is intersecting with the other character
3) break apart the characters and merge them into an "interaction manager" movieclip
4) just give up.
I don't have the skills for option 1. Option 3 is ok i guess, but i'd rather try option 2 first. My biggest problem is that i have no idea how i would go about selecting just the intersecting part of the movieclip without reprogramming some part of the display list. If anyone can understand this, please give me something to point me in a direction.

I'm making an isometric game and I need to know which takes less memory for scrolling, making everything invisible that you can't see? Like if(!this.base.hitTest(worldHitter))this._visible = false; Or would it be better to remove the movieclips unseen and then reattach them when i should see them?

if it is possible to load basic html web pages (like text) into a movie clip, or at least use actionscript to set the bounding box of the new window to have the same border region as the original movie clip (such as 600x400 pix at x+100, y+150, for example).
Alternatively, is there a method in which I could load several large scale text files into a region of a movie clip, without having to create endless .as files filled with thousands of

Well, I am working on motion detection in AS3.
I already understand how it works, now in this swf what happen is there are filters added to the video(output) to make the motions color white. I will put the files here.
The swf is inside the bin folder. (this is made by soulwire) Here is his site/blog
[URL]
I am trying to mod it to improve it. Well you can study code if you want to
But what I want to do with getColorBoundsRect is:
- Having only one source to detect the color "WHITE". But having multiple "getColorBoundsRect" detecting white on that ONE source but on DIFFERENT regions.
Lets say this M1(colorboundsrect) will only detect the first part of the source) and M2 will be detecting on another region of SAME source.
1 source, but multiple getColorBoundsRect on different regions of that 1 source

what I'm trying to do is allow the user to pick a section of the stage, click, and have the region defined be copied and show up on the other side of the stage. It may be better explained to think of it like a camera game. The player has cross hairs, can move the square (which tracks the mouse) around the stage, and click to capture that square's pixel information, store it to a new movieclip and display it on another area of the stage.
I've found many resources online about capturing BitmapData, including capturing from embedded FLV videos, but I haven't seem to be able to find anyone who has created something like this which captures from a moving region. However, I have seen it done before in a game that is no longer online from PBSkids.org.
Here is what I have so far. Right now, when I click the movieclip loads all white pixel data and I'm not sure why.
[flash=]import flash.display.BitmapData;
import flash.geom.Rectangle;
import flash.geom.Point;
stop();

to make a single-line text box auto-scroll a text string horizontally with a way to detect new words on the x-axis.I'm trying to make a rhythm practice game for ESL students at my college, but I'm a linguistics major, not a programmer.I want something that is similar to the vocal part in Rock Band (minus the pitch, for now)So for a simplified, proof-of-concept version I just need it to detect when a new word has collided with a defined region of say "100 < x < 50".I know how to implement the microphone using activityLevel to detect when the user is speaking into the mic, but just not how to use activityLevel alongside the region detect of the new word in the text box.

Coworker is developing a Flash project and has a small dynamic text field inside a movieclip. Imagine the text field being 200 pixels wide by 50 high, and sitting at the top of the canvas. As she moves her mouse around the LOWER part of the canvas, directly 'under' the text field, her cursor changes from the standard arrow, to the vertical bar (that is used for text selection). This is inexplicable and odd and is also interfering with her ability to do other things in the project. Has anyone seen this behavior? She has turned off 'Selectable' for the text field but that doesn't help things.

I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me. So I am going to try to ask my question specific to what I need to do.I have a set of points that describe a non-straight line (sometimes a closed polygon). I have a rectangular "view" region. I need to determine as efficiently as possible whether any of the line segments (or polygon borders) pass through the view region.
I can't simply test each point to see if it lies within the view region. It is possible for a segment to pass through the region without any point actually inside the region (ie the line is drawn across the region).Here is an example of what I want to determine (red means the function should return true for the set of points, blue means it should return false, example uses straight lines and rectangles because I am not an artist).
Another condition I want to be able to account for (though the method/function may be a separate one), is to determine not just whether a polygon's border passes through the rectangular region, but whether the region is entirely encompassed by the polygon. The nuance here is that in the situation first described above, if I am only concerned with drawing borders, the method should return false. But in the situation described here, if I need to fill the polygon region then I need the function to return true. I currently do not need to worry about testing "donut" shaped polygons
Here is an example illustrating the nuance (the red rectangle does not have a single vertex or border segment passing through the on-screen region, but it should still be considered on-screen):For the "does any line segment or polygon border pass through or lie on screen?" problem I know I can come up with a solution (albeit perhaps not an efficient one). Even though it is more verbose, the conditions are clear to me. But the second "is polygon region on screen?"PS I have a function for determining line intersection, but it seems like overkill to use it to compare each segment to each side of the on-screen region because the on-screen region is ALWAYS a plain [0, 0, width, height] rectangle.

i just wrote a radial preloader. i have a problem though: there seems to be some "residue". it is for a small gallery.. so when i test the loader using the bandwidth simulation, the first time it look perfect, but the second time, i can see part of the preloader from the first frame, and as soon as the preloader reaches the leftover region, that region is cleared.
