I 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 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.
View 2 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 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'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.

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);

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.

I am looking to change the background color of a input textField when the user selects that testfield to start populating it. I have done a bunch of searching and I keep coming up with this type of answer...
Code:
myTextField.onSetFocus = Set(evt:Event){
// Change color
}
Problems...
1) Is onSetFocus/onKillFocus still available? From what I can tell it is not.
2) I have my text objects encapsulasted in a class so I do not believe I am able to do it like I have been suggested.
I'm using the following to remove a textFeild from the stage I then need to add this textField back to the stage at a later time....i tried using addChild the problem is the text that was in the text field prior to the removal is still in the textfield when i re add it......How do i remove the textfield and replace it with a fresh textfield at a later time?....using msgTa.text =""; is not an option.
View 4 RepliesI just recently started playing with cs5 and it's new features. I tried to rotate a textfield with the 3D rotation tool, but when you do this, the textfields gets blurry.And it seems like it's not a vector text anymore, because when you zoom in, it still is blurry.Is there a way to prevent that?
View 5 Repliesi would just like to ask why is the case that when i use embedfonts = true on a textfield, the textfield's text only resizes according to the textfield's height but not the textfield's width. meaning if i make the textfield's height bigger, the text also gets bigger in terms of height, but not width, can't the embedded font maintain aspect ratio according to the textfield height?
I'm only wondering about this because this is not the case when embedfonts= false
in as3 how do i get the text of a textfield to know when to line break according to the width of the textfield.

Attached is basically a recreation of the problem. What I'm basically trying to do is a tooltip window with 4 frames. Each frame has different textfields but also some the same. Like the "Weapon" frame has textfields called namebox, typebox, levelbox, and damagebox, while the "Armor" frame has namebox, typebox, levelbox, and defensebox.
In the attachment there is a Movieclip called awd on the stage. It has 2 keyframes in it called "Weapon" and "Drop" each with their own textfields but they are both called "box". I have a click event listener that makes awd go to its second frame and outputs the second child in awd, which will be the textfield. The problem is when I click the first time, awd goes to the second frame but it outputs null instead of Object TextField. When I click again it outputs Object TextField. If I trace the number of children it gives me 2. So I don't know how it can be null.
I've got a flash document using AS3. It dynamically reads data from an XML file, and creates a bunch of single line textFields. Could be like this:
<XMLdata>
<Line>this is line 1</Line>
<Line>this is line 2</Line>
<Line>this is line 3</Line>
</XMLdata>
So, for each node, it would create a new TextField, and change the textField.y value so that they are "stacked" on top of each other. All this if fine, except that if you hae so many "lines" (or textfields) that the "stack" is taller than the Flash Document size. What I would like to do is have a scroll bar or something so you can scroll the stack of TextFields. Doesnt' even need to be a scroll bar. Maybe an arrow button at the bottom, and when you click on it, it scrolls down. One for up too.
I have a numerical stepper,and a user can click on a textfield, then click the up and down arrows on the stepper to change the font size,i then try and set the focus back to the textfield and put the caret at the end of the textfield, but the stepper keeps focus anyway.Here is the event handler for when the stepper value is changed.Get the textfield's current format, change the size, set the new format, then focus on the textfield and set the caret position, but the caret just stays inside the stepper.
Code:
private function handleChangeTextSize(e:Event):void
{
var tField:TextField = Main.LAST_FOCUSED_OBJECT;[code]....
I've had problems with other components too with the exact same focus issue and the only solution i've ever come up with is to set a timeout for like 100 milliseconds to set the focus back then and it works. another way to do this without the "hack"?
