I need some help with trigonometry in flash mx. I was inspired by this site and was wondering how you do it...go to 'images'..I dont want to just copy and paste a script you would give me..
View 1 RepliesI have this game where a movieclip moves towards the mouse point by finding the difference and dividing by its "speed". This isn't very good though because different users will have different cursor speeds. What I really need is a method that finds the angle between the two points then uses that angle and a "speed" to calculate the next position of the moving movieclip.Here's something along the lines of what I am looking for but it doesn't quite work?The function runs and everything. All that works, it's just the maths that isn't right.Something needs changing with the maths.
ActionScript Code:
function moveCircle(e:Event):void
{
[code]......
From what I have gathered, _rotation uses radians?Basically, my initial goal was to make a movieclip rotate towards the mouse. I'm not very good at trigonometry.Using the help files I found atan2 which seemed to be what I needed. A little fiddling got me to this code:
var xDist:Number;
var yDist:Number;
var angle:Number;
onMouseMove = function () {
[code].....
However,the _rotation is opposite what is expected. This is not a problem as I can just flip the movieclip. But really what im here to ask is, please ecplain this code for me? I don't correctly understand how atan2 works.. and why it needs to be *60.Basically: How to get a movieclip to rotate towards the mouse.. and why does the code work, I want to learn trigonometry.
i know how to check the angle between my object and the mouse, but i dont know how to make it rotate slowly to it...
i tried this codes:
Code:
//first method:
onClipEvent (enterFrame) {
this._rotation = (Math.atan2(_root._ymouse-this._y, _root._xmouse-
[Code]....
Basically I have two movie clips. I know the x diff and the y diff, now how do I find the angle at which the movie clips are at?
Code:
v MC 2
/|
/ |
/ | < y diff
/ |
MC 1 > /__|
^
angle x diff
Is there someone who is good at trigonometry? I have two points punkt1 and punkt2 and a line that is drawn between them. Both points is dragable. I want the line to continue after the points in both directions and with the same steep. I have counted the steep between point1 and point2 and tried to continue to drag to a point with the same steep, but it doesnt succed.

I've got two concentric circles with their centers at (centerX,centerY). The inner circle has a radius of 100 and the outer circle has a radius of 400. If take a point on the circumference of the inner circle, I can draw a line from the center to that point. Let's call that point x1,y1). I now want to continue that radius out to the outer concentric circle and calculate the position of that outer point (x2,y2).
I'm adding a 3px 'dot' just to show where x1, y1 is on the screen. (Subquestion: I can't see it...not sure why.)This is what I'm trying:
var x1:Number = 100;
var y1:Number = 50;
var x2:Number;[code].............
This is my first post as i m just beginner in Flash JavaScript. I want to prepare a FLash Movie in which all the images r dynamic and the images should change after a time say every 30 secs the image changes.
View 1 RepliesI have a flash file sitting inside of a web page in our company domain. There is another server (used to store images) that is part of the domain but is not running any web services (for security reasons). A folder on the images server is however shared in such a way that any site on the web server can display images from the images server as long as the user is plugged into the domain. For example, both I and my boss can pull up a web site on the web server and see all the information, but only he can see the images
because I have Vista Basic and no domain support. This is done via "<img src='\serverNamedirectory.'/>"
That's ok, but on this particular instance I don't want to display the image on the webpage, I want it in a SWF on the page. However the SWF can't seem to load the images even though the page it's sitting in could. I've tried tons of variations of URLRequests and Loaders, most resulting in security errors. Since most of the online discussions about these errors revolve around cross-domain access, I can't seem to find any tech support for our specific situation.
i couldn't find a tutorial on this matter so i sorta started making my own hypothesis... what i'm trying to do is: have a gallery of images automatically scrolling horizontally while having the set of images loop. like at[URL]..
here are a couple of my theories and questions for AS commands to have this work:
1) display a range of pixels of an image at certain positions, i.e. if gallery is scrolling to the left, leftmost image when its parts are disappearing out of the viewing area, they become visible at the right.
2) have two instances of each image and when an image is disappearing on left, the second instance of that image comes visible on the right. this I imagine would take up more HD space.
i guess what i was wondering more about is how jager did their gallery where there's only enough images are in a set to be viewed in the viewing area.
Explaination: MX 04' Pro Thumbnail Nav. loading images with XML Loader resizes and displays images when users click on Nav. reading XML Problem: Users click Thumbnail Nav. first image gets loaded and loader resizes to image. However the next choice by user on thumbnail click, the second image doesnt get resized in the loader. It goes beyond holder. Here is my code for Thumbnail and Loader:
[Code]....
Now the first image loads fine and the loader sizes to file from XML. However, when users click second choice from Thumbail the loader doesnt resize to new image size. It only gets resized on the first selction or if users click the next or prev. buttons then the images fade correctly but nothing fades back in. Now if they do hit next or prev and then hit a thumbnail option it loads and resizes.
I am pulling external images, I have my main image, and five small images, I have that to make the small images when click to appear in the place of the main image, but I am not obtaining to make they to click, I am placing my archive who to want to make download
View 2 Repliesim loading multiple images but how do I make sure the program will start once all images have dispatched a complete event. like make a universal loader for all the other "small loaders" if you understand.
View 1 RepliesIs there a way using flash you can display images but each one selected randomly from say an array of different images?
View 4 RepliesI am trying to load multiple images into a scene and then cycle through the images one at a time.So, here are the essentials what I've put together in AS3:First I set up a counter and a Loader
[code]....
Then, after loading a list of images from an XML file, I call a function that I called "createImages". This function then takes the list of images and creates a bunch of loaders:
[code]....
So far, so good! I now have a bunch of loaders each with a different name "img1","img2","img3" etc.
I have a photo gallery that loads many images using a for loop (image data is from XML file). Simplified code looks like this:
Code:
var photos_xml = new XML();
photos_xml.ignoreWhite = true;
[code].....
I would like to have my background image change images every so often. I would like to use only AS3 for this. Could someone point me in the right direction. I am new to the language as well as flash.
View 3 RepliesI've tried a lot of online tutorials for photogalleries but can't find what I'm looking for.I need to bring in my images from xml so that they will fill the thumbnails (if the width of the image is greater than its height then it will scale to the height of the thumbnail) and center within that thumbnail.
Then, when I click on a thumbnail, I need that image to fill the space allowed for the large photo (this time if the width of the image is greater than its height then it will scale to the width of the photo space)and center within that space again.In terms if centering the image,I have created movie clips for both the thumbnail and the large photo space (let's call them "imageHolder")and within those movieclips there is an empty movie clip called "image" which is aligned to the centre of "imageHolder". I thought that this would work:
imageHolder.image._x = 0-(imageHolder.image._width/2);
imageHolder.image._y = 0-(imageHolder.image._height/2);
But no such luck.
As for resizing the images to fit the image holders,
the easy part is to create the image and the mask for it:
// The jpg
var elementImage:Image = new Image();
elementImage.source = "/assets/materials/9/main-body.jpg";
[Code].....
but that's not working here. the event listener reacts even if i hover over the trasparent parts.
if i draw an vector graphic and use it to mask the image it works just fine...
I need to load dynamically a few images (4-6) so that by clicking on particular image user would invoke particular action. Embedding images solves the problem but at the expense of file size. If I load them dynamically, they lose their ID.
<comps:ExercisesScroller id="scroller" x="300" y="100"
ex1="@Embed(source='assets/Exerc_1.png')"
ex2="@Embed(source='assets/Exerc_2.png')"/>
and so forth this works. But instantiated in CDATA it does not work:
import components.ExercisesSCroller;
private var custScroller:ExercisesScroller;
private function init():void {
[Code].....
is it better to import images to the timeline at runtime, or export them from the library for use in action script?
I have a few images which make up the background to my website (ie they are unlikely to change very often - if at all), which I am currently exporting from the library for use with my action script code, and the rest of my images I am dynamically loading in based on a set of paths held in a csv file (these may change often).
As I have already built the class to dynamically load in external images, I was wondering if I should also load in those images which make up the background.
I have downloaded this slideshow but cannot for the life of me figure out how to center the images. The slideshow calls the images from an XML.I have edited the width of the slide show just fine but the images are still justified to the left.
View 7 RepliesIn flash there are some n number of images like a list.If i drag on image and drop it somewhere between two images the images should arrange automatically as we changed. I have no idea of how to do it.
View 4 RepliesI am using actionscript 3. I can load an image in a class but how do Iload a number of images eg 4 images that animate.?These 4 images are a walking sequnce of a character. I am unclear after googling an loading multi images in as3( just love google).
Loading a single image I load this into a loader Once loaded I load the image into a bitmap and add to a sprite I then add the spite to the stage Q)Now for 4 related images I load 4 loader or 4 sprites or 4 bitmaps or do every thing 4 times?I want to do collisions eventually and I need bitmaps but bitmaps seem useless to use other than collisions.Googling for answers isnt helping me clarify this!

Here's the site: [URL] From feedback I've gotten, it appears that under certain circumstances the first image in a set of images does not load properly, although I haven't seen it myself. I'm told this happens only in Firefox. And I believe only Flash player 8. Works fine with FF and Flash player 9, or IE with 8 or 9 I believe.
View 14 RepliesI've got an animation in Flash that's made of a number of large images - too large it turns out - flash keeps crashing and running out of memory.
I'd like to scale these down to 50% but maintain their on-stage size in Flash (or at least keep the positioned the same). I've scaled them down on disk, but this scales them in flash too (so messes up their relationships).
I`m currently working on a website in flash which is going to be kinda like a blog. The swf loads in in two files for each "post", one image and one text file. I already know how to do that. But the website has to be update able without using flash. How would you do this? I thought i maybe could have one folder named "posts" and in that folder i could have folders named something like "post1", "post2" etc. And the post with the highest number would be the newest one. Something like this:
Can flash read directories on the server? (but i cant get the search to work. Neither in Chrome nor IE. I just get HTTP error 500)
Why does flash messes up(slightly) the images colors?
here is the original image(left) and the imported/loaded(right)
I mean I've got buttons, motion, etc and some actionscript down pat however I sourced this awesome 3D box from Kirupa and I just need to alter one thing with it.I'd like to add images to the different faces. I'm guessing loading the images into an array and then calling them is the way to go? I've played around with a few thing but taken them all out of the actionscript because they didn't work.how to attach these images? I'll attach my fla oh and I'm using AS2 at the moment.[code]
View 1 Replieshere is some code for a rotating crank that controls an image gallery. refer to the "image viewer stops?" thread in the flash mx forum (sorry don't know how to link to a forum yet!) for more info. attached is the fla. i want to be able to crank clockwise to scroll images forward and counterclockwise to scroll images backwards. If i keep cranking, i want the images to continue to change, if i stop cranking, i want it to stp on that image. it doesn't sem tooooo hard, i'm just numb from tryig to figure it out.
