ActionScript 2.0 :: Using Whatever LineTo(); Draws As A Mask?
Apr 30, 2005
The effect I would like to create is as follows: I have an image movieclip named "myImage_mc", and I want to create a spray paint effect, where the user "paints" whatever myImage_mc is using the lineTo and lineStyle commands. I have the lineTo stuff all done, the problem i have is trying to make whatever the user draws a mask that shows the image.Here's my code so far:
I opened up the NY Times homepage, and they have this giant Apple addvertisement that has animations over the entire top half of the page, outside the area occupied by the swf.
There's something I'm trying to make but I just can't seem to figure it out. I want to make something that allows a person to build a deck of cards from multiple sets of cards. I also want a button that can be clicked to randomly choose a card from the created deck. For example: lets say there are four sets of thirteen cards (hearts, diamonds, spades, and clubs). The user can select which of the four sets will be included in the deck. Once the sets are chosen the user can click a button and one card will be chosen from the selected sets. What is the best way to handle something like this? Is there a tutorial that explains how to do something like this?
I'm having an issue with Flash CS4. I'm not sure what I toggled, but when I draw a line or shape it automatically converts it into a symbol. How do I disable this? It's very annoying to have to break apart each line as I draw it.
I want to write a program that draws a Pythagoras tree. The only programming language I know is C but I tried it in that language and it was horrible. Someone recommended Flash (AS3) to me so I am trying it in that now, but I only started learning it yesterday. Anyway, I got to the point where I can draw the leftturning branch of the Pythagoras tree, but I don't know how to draw the other branches. The number of "houseshapes" a square with a rectangular triangle on top increases with every step according to the formula 1 x 2^(n-1) (First step is n=1). I created a function that draw this houseshape, called drawHouse() and it takes as its arguments the co-ordinate of the lower left corner of the square part of the house, the length of the side of the square part of the house and the current rotation angle. Rotation angles are always multiples of 45 for now, but I might try to expand it to other values later, but for now I hardcoded a lot of stuff that assumes the 'roof' of the house is a rectangular triangle.
The orange square is the currently selected selected sprite. The sprites are all draws from coordinates that i receive from XML. var sprObject:Sprite = new Sprite();
[Code]...
What I want to do is the following. If I'm currently on the orange square and I use my keyboard direction buttons (up/down/left/right). I want to deselect the current sprite and select the next sprite in the appropriate direction. The problem I'm having is that I cannot get the x and y coordinates of the drawn sprites. If I look in the array, the x and y coordinates of the sprites are all 0. If I can retrieve that I can write an algorithm to determine the next sprite to select.
I am working with a flex project with a main mxml file and two actionscript classes that draw graphics. From reading tons of articles and posts I discovered that they must extend UIComponent, which they do. The first actionscript class draws the image fine. The first class then makes the call to create a new object. The second object does not display. In the pure actionscript version I had to pass the stage as a reference for the second class to draw.
I also found a similar question here at stackoverflow:UIComponent extended class isn't showing UIComponent extended class. But I was not sure how to apply it to my example.Which, if any UIComponent methods should be overrided for the second object to display? How specifically should I implement them in this example?
// First class "Ball" draws a circle successfully then creates a second object "MyRect" package dr { import flash.display.*; import flash.display.Sprite;
I'm intermediate in AS2, and I'm starting work on custom classes. I am making a class called VolcanicIsland and I want it to make a movieclip on the stage when it is called. I do NOT want to make a variable MC that gets put into the arguments when it is called, however. Here is the external AS file (trimmed to the problem area):
ActionScript Code: class VolcanicIsland extends MovieClip { //position private var x:Number;
I have a Dot class, which draws a dot with a color of 0x00FF00. When I click on the dot, I would like it to change to a random color from an array of colors I have pre-specified.How can I replace the current color with the new color? Do I have to re-draw the circle (dot)? or can I just replace the color?
I'm trying to make an Etch-a-Sketch kind of game for fun. I think it's a simple problem, but I tend to type a lot of stuff for some reason. I found this code to build upon:
ACTIONSCRIPT Code: createEmptyMovieClip("Line",1);Line.lineStyle(1,0x000000,100);onMouseDown = function (){ Line.moveTo(_xmouse, _ymouse); onMouseMove = function () {
i created my own Button which simply extends from Sprite.Its able to show 3 different text fading in and out using a timer.In my draw function i first draw a rectangle with the Sprites graphics object representing the background of the button.I added a function to set the button width. This property is used to draw the rectangle. I know that the sprites's size is updated after the rectangle drawing. But for some reason the sprite's width is always more than what i have set via my "setButtonWidth" function.Now i have a simple sprite acting as a button having a graphics.drawRectangle part drawing a simple rect. with lets say 500px width. But when i trace the width of that button it is always about 10% more. Where are these 10% coming from?I read about calling validateNow(). But this is only for Labels, or Checkboxes. For some reason i cannot access the library for Label. This must work somehow with TextFields. But how?
// this function is part of MyButtonClass.as file function drawButton() {
how I can create a movie that draws a shape on screen.
I understand how to draw a line, etc but can not work out how to see the shape build. I do not want something likes Kirupas' drawing demo as I do not want the viewer to create the shape.
For example I want to see the lines being drawn and control the speed, rather than the shape simply appearing in the movie.
I realise I need to change the lineTo value
An example is the way the TV is drawn in [URL] although I am not sure if this uses actionscript or is something else.
I am drawing a flash sprite on a BitmapData using its draw() method. This sprite has some nested objects with 0 alpha, yet the draw() method draws them on the bitmap data.
I think it has to do with the color transform I am using, but I have no idea how to change it to achieve the effect I want.
The color transform is the following:
Code: new ColorTransform(1, 1, 1, 1, 255, 255, 255, 255);
I am using these values in order for the Bitmap to have white pixels wherever the object was, and black where there is nothing. The draw() also draws my alpha = 0 objects in white as well.
Download the attached file and test it. Wait a few seconds, maybe 10-20 sec, and then se the a bug appear. It looks nice, but why? I was just playing around with lineTo and then i saw this... What do you think ?
I have a startDrag function set up on a loader and mask that when the mouse is down on the loader it drags, when not it doesn't. There is also 2 buttons that control whether mask1 or mask2 is used. What i would like however is when the mouse is down - the area of the loader outside of the mask is visible but only by about 10/20% alpha, that way the user can see where all the image is while dragging. Is this possible? Full code can be seen below and i have attached the zip with the .fla file:
I have wrtitten some code that draws a couple of lines with changing alpha and width whenever the mouse is moved. I need to convert this code to AS3 so that I can use it in conjunction with some video tracking.
Code:
var speed:Number = 100; var myNumber:Number; var myMax:Number = 50;[code]...
what i am doing is to make something along the lines of the "scriptable mask" tutorial Inigo was kind enough to put up.My idea is to have a large mask behind the whole of my flash site, this masks a colour image with a black & white one (nothing tricky). The image I am using is actually 5 separate images combined, and each is a pic of certain parts of the site.I also have a very basic set of buttons along the bottom... each corresponding to each section.
All I want is to set it up so that when I mouse over the buttons, the _x of the mask moves to correspond with the correct image... really very basic... or so I thought .If anything it should be easier to do than what is in Inigo's tut (where he uses the _x of the mouse to move the mask)... i just cant seem to get it to work with a nice easing effect (its easy to get the mask to simply snap to each coordinate, but I need it to smoothly move).
I am making a demo where an object is moved around the screen with a line tracing its movement. The speed of this noticeably slows down over time. I tried it both with an enterFrame and by setting an interval. I imagine it has something to do with the graphics class vector drawing and garbage collection. Here is a simplified version for demo/testing. If you run it you will see the line drawing slow down over time. Is there a way to achieve it without the slow down?
I read somewhere of a technique where you use the bitmap data class to draw on a stage-sized bitmap.(I've never programmed the bitmap data class before).
Here is the code:
code: var lineX:Number = 100; var lineY:Number = 100; var deltaX:Number = 10; var deltaY:Number = 10; var lineDrawing:MovieClip = new MovieClip(); this.addChild(lineDrawing);
I'm making a shape (christmas tree) which i can't make with rectangles and circles exc, so i made it with moveTo/lineTo, the problem now is that i can't "call" for it to fill the area inside the shape... how would you do it? Also, i hope i did this the wrong way, because its a really tiresome way of making it. What I've got so far is:[code]
I have this file http:[url].... Basically lines gets drawn where ever I tween the animation.arrow MovieClip. What I'm wanting to do is be able to rewind the MovieClip and have the line erase its self step by step.
I'm looking to work out the most efficient way to maintain the joining of two points with a line in AS3. Basically, I have a whole bunch of circles that move around, and have a property subNode which will act as an end point for the line. At the moment, the way I'm doing it is extremely intensive:
I have been working on a drawing "game" in my spare time (which is limited). This is probably a common question, if so I appologize. By the way, I do not have the code here, it is on my other computer. Anyway, I was using the lineTo method and a timer listener to fire the addition of each new line segment, if that makes sense. The problem is that when you try to draw an arc quickly, it looks terrible. It draws straight lines. I tried adjusting the timer, which helps a bit but still not great. I looked at the curveTo but could not figure out a logical way to get the achor coordinates. I did some research online and found some that use addChild with bitmaps. I would rather use lines. Has anyone tackled this before?
I've got a movieclip of a rectangle in my library which I place on stage to attachMovie. Then I create an empty movieclip which I want to use as a mask on that rectangle clip through setMask. Users kan draw into that empty movieclip. My intention is that only those areas of the rectangle clip become visible where the user is drawing a line. So I used this:
I would like to draw a shape with LineTo (following a motion guide) and having this drawing synchronize to the duration of a sound : if the sound lasts 2 minuts, the drawing should take 2 minuts to be drawn.
