Actionscript 3 :: Image Circle Mask Using Adobe Flash
Apr 27, 2011
I am wanting to achieve a particular image effect using Adobe Flash (Actionscript 3). I would like an image (width 200px, height 600px) to appear on the timeline by being revealed by different sized circles (varying from 30px-5px). I am thinking of using an image mask and creating seperate circles across the timeline, so that when the movie plays, each random sized circle, one after one, will reveal the image at the end. So this is probably going to be quite time consuming. Also, does anyone know of any flash image effects helpers in general, I'm looking for something similar like green socks except for image effects...

From this tutorial:[URL] Pretty neat effect, I wanted to use this for a gallery transition, but I have a problem. Does anybody have an idea how to know when image has been completely revealed so I can stop the enter frame listener and remove this growing masks, otherwise this is pretty useless

I've made a image slider Class and works fine up to the position of the mask. In my Home Class I make an instance of the image slider Class and position it accordingly. The images in the slider Class are position at 0, 0 as well as the shape I use for the mask. Here is the problem the mask placement is at stage.x = 0 , stage.y = 0 rather then the slider's Class x:0, x:0. Why is the slider instance showing the in right position but the mask in the instance isn't?[code]

I am looking for the most efficient way to create a circle mask on a BitmapData, so that everything inside the circle is visible and everything outside the circle is black. Here is my current code:
[Code]...
As the radius of this circle is going to be changing rapidly, storing the mask would be useless. how to make this more efficient, preferably keeping to methods that can use GPU accleration?

So I've made a circular preloader made with some shapes and masks. Everything like this works. What I want to do now is add a movieclip of animations to the stage and make it look like this movie clip is in the progress circle of the preloader. So what I did is create a movieclip container to hold all of the shapes that animate on loading. I then used that movieclip container to mask the movieclip of animations.What happens when published is the movieclip of animations (the particles) loads over the shapes, but all of their masks are gone. So it's as if when I applied the mask to the container, all of it's children and their masks stopped working. Is there a way to correctly do this?

Does anyone know how to mask in a circle? To try to clarify: If you had a clock face with the minute hand at 12, as the minute hand sweeps round it reveals a picture. Here is an example of what I'm looking to do (the orange logo at the top)[URL]

Code:
for (i=0; i<200; i++) {
circle.duplicateMovieClip("circle"+i, this.getNextHighestDepth());
randX = Math.floor(random(Stage.width));
randY = Math.floor(random(Stage.height));
this.banner.setMask(this["circle"+i]);
this["circle"+i]._x = randX;
this["circle"+i]._y = randY;
}
Circle is a movieclip that has a circle starting at 2px by 2px and expands to 100 by 100. Banner is just a movieclip, but I would like these expanding circles to act as a mask to reveal the banner. This should work, but isn't, I know I am overlooking something.

maybe point me towards a better way to mask. png file is way too big. I have been using the mask layer option to create my own mask around a jpg image by drawing around it on the mask layer. There has to be a fetter and faster way to do this. Is it possible to maybe have a specific color range have an alpha value of 0. Similar to green screening whereas If I put the item I want to clip on a green background flash will auto take out the green for me. and by auto I mean action script maybe. I think this can be done but im not finding it.
how are these guys clipping these images [URL] they have the movie clips set up where the black background on the 3 layers of shoes is getting masked out. When I go into the shoe movie clips I see there is a black background but it just disappears when I go back to main timeline.

I'm just starting out with Flash, I'm using ActionScript 2.0, and trying to acomplish something seemingly simple but it is not happening like I would think it should,'m trying to load a large image about 3000x2000 pixels and then mask it with a small square, so that later I can scroll through the image to view it.Here is the code I have so far, it produces a blank white screen.
createEmptyMovieClip("container", getNextHighestDepth());
container.createEmptyMovieClip("fullImage", container.getNextHighestDepth());
//When I replace the above line of code with the line of code bellow the image is displayed

I've been trying to open a jpeg image in Actionscript 3.0 which opens without any issues however part of the lettering in the image appears to display as a different colour as if Flash doesn't recognise the colour in the image. The strange thing is that it opens in photoshop as the correct colour but not in Flash. Would the colour scheme that the image uses perhaps need to be added to Flash database of colours?

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 have a magnifying glass image on my stage fixed on the right hand side, with the glass area of the magnifying glass cut out as a movie clip called glass_mc.
Now i also have a map to the left of that image. What im trying to do, is when you roll over the map, a zoomed version of that map will appear in the glass zoomed in or out depending on what zoom level i make it.
I have got it working using a rectangle but how would i go about placing the bitmap into the circle so the zoomed bitmap is displayed is as a circle shape.[code]...

Basically I have a background image which is loaded while the rest of the flash file is loaded. So once the preloader has finaly appeared its already half way through which I dont want.
Is there a way I can specify a certain image to be loaded before everything else in the flash file and before the first frame to start?

Is there any possible way to play a .jpeg sequence using .flv player on-the-fly ? I mean, by not needing to convert the entire sequence into one single .flv ? Since I'm not familiar with flash neither action script, I was surfing the web in hope to find any template or tips about similar things to that but I couldn't...
Here's the main list of features:
1- Browse button to load a sequence eg. < filename >####.jpeg
2- Play button with a slider time
3- Previous and next frame-by-frame buttons
4- FPS slider from 0 to 30
My main reference is this stand app called Cyber-D's Image Sequence Viewer.

I have a Flash file for an advanced preloader that fills up a circle with an image as the file loads. The problem is that the readout on screen is the percentage loaded. I am trying to get it to read kilobytes loaded over the total number of kilobytes, with the image synchronized with the amount loaded. I can actually send you the .fla file via e-mail so that you can see what I have.

I recently tried using a png image from the library as a mask for a movieclip on stage. Much to my surprise, the mask is just a rectangle. I expected it to ignore the 0-alpha pixels in the image and just mask out the visible shape. I managed to come up with a work around, but I just wanted to know if it was possible to use a png image as a mask and get the shape of the visible image as the mask as opposed to the whole, rectangular image area. I totally thought it was.

I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?
