Actionscript 3 :: Erasing A Layer Where Mouse Is Over It?

Jul 18, 2011

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?

Flash :: Detect When Mouse Is Over HTML Layer Over Movie?

Jan 13, 2010

I have a Flash movie that is embedded in an HTML page that has a DIV in a layer over the top of the movie. The Flash movie scrolls based on the mouse position over the movie. The client wants the scrolling to stop when the mouse is over the DIV. I've tried using the mouseLeave event, but that is not triggered by the DIV.

Is there a way that the Flash movie can detect when the mouse is over the DIV?[code]...

ActionScript 3.0 :: Erasing Drawing From Stage?

Jan 12, 2010

I 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);

I'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.

ActionScript 2.0 :: Blendmode - Erasing One MovieClip From Another

Nov 10, 2009

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).

ActionScript 3.0 :: Erasing A Circle From Bitmap Data?

Sep 29, 2009

I'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.

ActionScript 3.0 :: Slow Performance With Bitmap Erasing?

Nov 26, 2008

for 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);

ActionScript 3.0 :: Pixel Have Changed To Get The Percentage Of The Complete Erasing?

Feb 2, 2010

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)

Flash :: Erasing A Specific Selected Portion Of A Bitmap?

Apr 20, 2011

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.

ActionScript 3.0 :: Convert Layer To Movie Clip Or Print Layer?

Aug 9, 2010

Im creating a program that is designed to allow the used to select  3 pictures (movie clips) and print them off on a single peace of paper.

The program works by allowing the user to select 3 graphics (the graphics are actually instructions for various exercises) and then moving the desired movieclips onto the stage. This all happens on a layer named "Content"

So far the program will allow the user to select the movieclips and will move them into place on the Content layer as well as move smaller versions of the pictures into a preview box the only thing it does not do is print. (the most important bit)

ActionScript 2.0 :: DragOver - Drawing White Line By Erasing Dots

May 19, 2010

I 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;
}}

How To Have Outline Sketch On Layer A And Color On Layer B

Nov 5, 2009

I'm trying to do a little comic comedy type video in Flash. I've done an outline sketch with the pen tool of my first character, now I want to color it BUT I want to keep the colors and the outline sketch separated on two different layers. Is there a way I can select the path (outline) on layer A and then colorize it with the bucket tool on layer B? The problem I'm having is that every object I select it automatically jumps to that corresponding layer.
 
One reason why I want to do it this way is I still want to continue working freely on the outline sketch since it's not fully finished, so that I just can blend the colors out and keep working on the outline, at the same time I want to color it while I go just to see where it's going and to make sure that I'm not wasting my time unnecessarily with trying to do a outline just to find out that it won't work out at the end.
 
how to do a comic type animation, how to create the characters, how to make them move and talk? It can be a free or paid resource.

Is it possible to add layers, re-order layers, move movieclips from layer to layer or specify which layer a duplicate movieclip appears on at runtime with AS3?I am aware of the depth properties and the functions associated with that but it would be easier to have a concept of a layer because I am dealing with masks.I have a nasty feeling I'm gonna be told that layers don't really exist within an swf and that depths and setmask are all there is to work with.
