I have a fully working flash application, made in as3. Now i dynamicly added a movieclip and i would like to be able to erase that movieclip with a eraser of some sort, my goal is to be able pick up a sponge with the mouse and then start dragging over the movieclip and erasing the parts where i dragged over it.

I am trying to erase one movieclip from another using the blendmode="erase" setting, but can only get it to work on the stage as the parent. This means it erases a hole through everything! The attachmovie also doesn't seem to work as I was expecting and I was hoping that when you drag the movieclip, the attached clip would move with it? If you check out the FLA [URL] you can see whats happening right now and what I want to achieve (diagrams provided in FLA).
View 1 RepliesI tried to erase whatever was drawn on the stage by using a similar function in a recent previous post but I'm not getting it.when I try to use it an error says that this is no longer supported. I tried addChildAt() and inserted different Num but it only erased everything including my button.the current code is:
var drawing:Boolean = false;
this.graphics.lineStyle(5,0x000000);this.graphics.moveTo(mouseX,mouseY);
this.addEventListener(Event.ENTER_FRAME, onLoop, false, 0, true);stage.addEventListener(MouseEvent.MOUSE_DOWN, onDown, false,0,true);stage.addEventListener(MouseEvent.MOUSE_UP, onUp, false,0,true);
[code]....
The problem is when background of top or below label is changed, the top or below button is erased.
<mx:Canvas width="100%" height="100%">
<mx:LinkButton icon="{icon1}" width="25" x="10" y="10"/>
<mx:LinkButton icon="{icon2}" width="25" x="10" y="100" />
<s:VGroup width="100%" height="100%" id="lst" click="highlight(event.target as Label)" gap="0">
<s:Label />
[Code]...
So do anyone know the possible solution for this problem?
I got the following question.
i added the following elements to the stage:
homeBg = new HomeBg();
homeMask = new HomeDrawBg();
addChild(homeBg);
addChild(homeMask);
I allready instantiated them in the beginning of the document. But my problem is the following. the homeBg layer is a image, the homeMask layer is the same image but it has a pencil scetch look. What i want is that wherever i move my mouse, the homemask layer should be erased so the bottom layer becomes visible(only where the mask is erased). So how can i tell the mask layer to erase itself if the mouse is over it?
I'm attempting to create a dry erase board style animation effect in my flash movie where I'm erasing the text, like a dry erase board type effect. I've tried doing a frame by frame mask animation and it's not turning out very well. Has anyone attempted this before? Are there any tutorials or maybe after effects > flash tricks?
View 2 RepliesI'm in need, again, of some assistance. I'm making a game with 2 pictures. and the concept is built on that you erase part of the top-bitmap to see the bitmap under.How can I accomplish this?I tried to wrap my head around the bitmaps and the draw and the FillRect but can't get it to work completely.Basically I want 2 bitmaps, and a cursor which erases parts of the top one to show the one underneath.
View 5 RepliesI'm trying to create sort of an eraser to remove sections of a bitmap on stage.
I have achieved this by creating a MovieClip in flash that is a circle and exporting it as a Class called Hole.
Now I use this MovieClip to erase a circle section of the image using the following.
var mat = new Matrix();
var ct = new ColorTransform();
var hole = new Hole();
mat.translate(x,y);
image.draw(hole, mat, ct, "erase");
Now what im trying to do is scale the size of the circle depending on a certain variable but no matter what I try the scale doesn't seem to change and. The size seems to stay the same as I drew it in Flash. I tried adding the following line
hole.width = hole.height = size;
I even created a class file called Hole and the size as a parameter
var hole = new Hole(200);
This didn't work either it still appeared to have the same size. I have even tried altering the scaleX and Y values with no success.
flash: Erasing area dynamically?
View 2 Repliesfor the past couple of weeks I've been learning AS3, and for a school project I'm doing a remake of the popular DOS game Liero. Everything is working fine, I got a layer of dirt that I am shooting away, but the problem is that after a few hundred bullets, the game starts to lag heavily whenever a shot is fired.I'm using a simple bitmap and a brush to erase the parts where the bullets hit.
// Drawing stage
bmap = new BitmapData(1100,800, true, 0);
dispBmp = new Bitmap(bmap);

How can I erase lines I've drawn using

I'm working with Threshold on BitmapData class. I need the threshold return the modified pixel (the pixels match with the equation).I need to detect how many pixel have changed to get the percentage of the complete erasing! I did it with getPixel32/setPixel32 but it's faster with threshold (i'm doing it on 15 bitmapdata at the same time)
pixelChanged += bmp.bitmapData.threshold(bmpBrush, bmpBrush.rect, new Point(this.stage.mouseX, this.stage.mouseY), ">", 0);
so, each pixel bigger than 0 should match this equation ... and they will be set to 0 after that (default color value). Next time, because they are 0, pixels are not suppose to change again because 0 is not bigger than 0 ! But it still return me a value, like if the pixel have changed! I've tried with different combinaison of mask/threshold .I join a sample of my problem (drag the triangle and check the output window ... the number increase even if the pixel is transparent 0x00000000)
I have two layers namely topLayer_mc and bottomLayer_mc. The actual vector drawing is drawn on the top layer and onmouseUp of the tool, a bitmap copy of the vector graphics on the top layer is taken and added as a bitmap to the bottom layer. The top layer is cleared subsequently. It is working for the pencil tool.Now I need to create an eraser tool. This is where things get tricky. In the application there is an option to save the image as png, so alpha has top be preserved. So the coventional method of draw a brush using the vector and using the draw method of bitmap will not work. Of course, on a visual level it would work if the brush drawn using the vector is to have the same color as that of the background.
What I need is to excatly erase the pixels.Now I have created a brush tool using the conventional technique and clearing is possible but what I need is to exactly erase the pixels. Is there some technique to draw this ? This is the code that I am using: I have also uploaded the swf and source code, When trying out, please draw all over the stage using the pencil (press Pencil button and start drawing)The source fla is also provided.
I've got to build a kids game at the moment for my school, and I was planning to have a sort of archaeological dig, with the kids required to rub the screen (it's for a touch-screen) to "un-earth" the bones underneath.I was thinking of either erasing an overlay and checking for a hitTest between the two objects, or coloring in with a line or something.Is it possible to color something in and check when the object has been completely colored? or possible to erase an overlying object? and if so, can you point me in the direction of a tutorial or a quick explanation?
View 2 RepliesI have the raster of dots on white background. I would like it when I DragOver each dot it becomes white so it looks like you are actually drawing white line by erasing the dots. Ive somehow found the way how to do it by making it transparent when I rollover. But it doesnt work with dragover. How to do it only when I hold down the mouse button and drag my mouse over the dots?
This is the script assigned to MC with one black dot (I copied this MC with one dot into another MC and multiplied it to have the raster):
this.onRollOver = function () {
this._alpha = 0;
} this.onPress = function () {
this._alpha = 50;
}
I've tried also this, but it doesn't work:
var erasepoint = false;
this.onMouseDown = function(){erasepoint = true;}
this.onMouseUp = function(){erasepoint = false;}
this.onRollOver = function () {
if(erasepoint){
this._alpha = 0;
}}
What (if any) is the actual differance between removeMovieClip() and unloadMovie() for use in erasing duplicated movie clips (using duplicateMovieClip() )? I was looking over some of my code and noticed I used both without much rhyme or reason as to why one over the other.
View 4 RepliesI am using Actionscript 3 to dynamically add text the screen (stage) with the TextField command. The problem is when I navigate to another screen (frame), all the text that was added stays on the screen.
how to make the text for only the frame that you want it to show up on?
I've written a simple MovieClip replacement that converts an existing imported MovieClip to a sequence of BitmapData. This removes the requirement for Flash to render vector data in the MovieClip on each frame.
But BitmapData has a huge memory footprint. I've tried converting the BitmapData to a ByteArray and using the compress() method. This results in a significantly smaller memory footprint. But it has proven impractical. For each redraw, I tried uncompressing()'ing the ByteArray, then using SetPixels to blit the data to the screen, then re-compressing() the frame. This works but is terribly slow.
So I was wondering if anybody else has an approach I could try. In Flash, is it possible to compress bitmap data in memory and quickly blit it to the screen?
I wonder how native animated GIFs work in Flash. Does it uncompress them to BitmapData behind the scenes, or is frame decompression done on the fly?
what I'm trying to do is accessingsnapText = scrollPane.source.textSnapshot;from an external swf. I've tried:

trace("-->: "+mc.textSnapshot.getText(0, 1000));

I am trying to activate a rollOver-function when the mouse rolls over a movieclip inside of a movieclip.On the main window (root), first you rollOver a button where a window shows up with more options (movieclips).From stage, my first movieclip is called "catapultas_read_more" which leads to amother movieclip called "pic1_mc". The label that is going to play when mouse over on pic1_mc is "rollOn".I tried this.gotoAndPlay("rollOn); directly inserted to the movieclip, but the movieclip inside pic1_mc never starts

I have movieclip which contains child movieclip. when child movie clip finish to play i want to run a function in a parent movieclip. so I made a custom event dispatcher in the first frame of the child movieclip:
[Code]...
My goal with this actionscript is to create a new movieclip for each top-level XML node and include in the movieclip two separate textfields, an image, extend the movieclips to two row if necessary, rotate each movieclip differently depending its parity and add a hover event based on the movieclips instance name. I have achieved each goal except for the hover bit. The reason I cant access the instance name outside of the for loop is because the instance name only lasts for duration of the loop. Here is my current code (at pastie address).

i have 2 intersecting movieclips.
is there a way to hit test point NOT detecting a bottom movieclip if the mouse is over the top movieclip?

what's causing the textfield to suddenly take precedence and how do i stop it. when i trace the evt.target - it is my movieclip.
Okay I have a script in which I have added an image to the stage. It is absolute centered. I then have another with is on top but much bigger. I would like the big image to move opposite of my mouse position on the smaller image. ie: cursor is on bottom left corner the bottom left corner of the larger image is in the same spot. And the same thing for any other area.
I have tried many different ways but to no avail. I have done research but no one has been able to give me a solid answer. Anyone know of a way to accomplish this. Keep in mind this it needs to work regardless of the image size.
I have a movieclip instance named 'placeholder' on the canvas, and I want to change the alpha of the named movieclip from it's class without effecting the alpha of all the movieclips of the same type. How would I specifically target the named movieclip instance that is on the canvas?
