I need to determine if a ray from a point (point and angle or vector) which goes to infinity intersects a line segment (two points), and if so, what direction it crosses (left or right.)I've been searching around on google but haven't had any success implementing the math solutions.I'm trying to do is implement the winding fill rule described here to determine if a path is clockwise or counterclockwise.
View 2 RepliesActually my project is about dynamic readjusting of nodes i.e. let say if you have 15 nodes( assume point objects) and suppose lines are drawn between any randomly selected two nodes,then the corresponding figure obtained should be readjusted that no two lines should intersect except at nodes.

i did the tutorial but something is wrong cuz when i created my own little sliding thingy and i put my mouse so it slides left or right on the right side it cuts off a bit when going infinite.I think its something to do with the positioning of my menu because its not on x=0 its on x=120.8 and i was trying to work out how to fix it but i'm stuck...and when i move the menu to x=0 it works nicely.
Not sure how best to put this into words Ddoes the depth manager always keep one on top of another, or can planes intersect, overlap, go through one another?
View 1 RepliesI have been playing around with the fmx2004 drawing api. I am drawing a complex shape and all is well but I would like to make the lines smoother. I haven't been able to find a smoothing function but I am working on a custom solution using the curveTo method.
I have to be able to calculate where two lines intersect. i have their slopes and two points along each line, so now all I need to do is calculate their intersection. I can do it on paper but not in flash

View 5 RepliesLooking for any info on how to determine the overlap of two shapes created with AS3, and preform the usual shape manipulations on them, like combining the two shapes together to create a new shape, punching the overlapping shape out of the underlying shape, or creating the intersecting shape from the two objects.
View 5 RepliesI have a MovieClip that has four circles on the stage. Each circle draws a line to the other three circles. I'm trying to figure out how to find the intersect point between all of the lines. If there is no intersect point, then the circle in the middle should become the intersect point. I've uploaded the SWF here: [URL].
Here is the code for generating the lines:
ActionScript Code:
package {
import flash.display.*;
import flash.events.*;
import flash.geom.*;
import flash.sensors.Accelerometer;

i have an xml file and i want my code in flash to read it line by line but its only showing the first line out of 5 lines.Below is the code:
var NigeriaNumber:Number;
var stateName:String;
var year:String;
[code].....
Shouldn't flash detect these before running the script and crashing and having to force quit and restart (and flash startup takes a while)? Like just give an error: infinite for loop or something? And this happened to me a bunch when working with for loops within for loops, when I accidentally used the same variable for both loops, so of course it never ended and crashed flash.
View 2 RepliesI'm trying to work out how to create a simple demo that works as follows: A ball falls from the top of the stage.Player is able to draw a line anywhere on the stage. The ball will bounce/roll along the line such that the player can guide it at will. I don't think the coordinate rotation will be a problem for me but I can't figure out how to transform a line drawn by the player into a hit detectable sprite -- or realkly any way that I can get those line coordinates into my coordinate rotation routine. To keep it simple, I'm just working on the first part of the problem, getting the line to where I can hit test or know its position.Here is my code so far:
package
{
import flash.display.Sprite;
import flash.events.MouseEvent;[code]........
It always traces 0,0 instead of my current line coordinates - and even those I don't think would be sufficient.
in Flash CS4 I have static text like: Line1 and line2 It's in 9 point Arial Regular as a device font. If I set the line spacing below 3.9 the second line dissappears from the compiled SWF file. It still shows in the FLA file. The same thing happens at 6pt but NOT at 5pt or less.
View 1 RepliesIs it possible to load a text file using line breaks as a delimeter rather than having a &var= at the beginning of each line? Like by a for instance? I have a text file with about 1000 lines that I need to load/display.
View 5 RepliesI'm in the process of teaching myself the components of the CS4 Design Premium package using the Adobe Classroom in a Book series. I'm currently going through the Flash CIAB and i've started using the pen tool. The task involves creating a wave like design across the stage. Whilst this in itself is simple, the final instruction is to click on the first anchor point to close the shape. In the illustration, the closed shape seems to automatically extend around the stage, however when I click on the first anchor point, the line automatically connects between the two points in a straight line.
Am I doing something wrong? The next step is to fill this area, but with the straight line effect that I am getting, this becomes impossible. I should point out that the instruction states that the pen tool line should extend off the stage. I have done this, but even then on clicking on the first anchor point the shape is closed incorrectly.
I am trying to dispatch an event but not sure when I should do it to get the right results. The first event "submitClicked" is in the right spot and works great. However, the second event "dataReady" seems like it might be a problem. I need it to be dispatched after this.compiledFormData is set.Does AS3 wait for each line of code in a function to be executed before moving on to the next line?

I am using Flex 4 and AS3 and I am trying to make it so that the user can draw a freehand line with the cursor - I have this part done.However, I also need the line to be a dashed line instead of one solid line like it is now. below is my code I am using. I have found some examples on how to do this, but they are all for straight lines, not for a freehand line.

When a Dynamic Multiple line text field is used in Flash CS3, it has a very annoying feature that auto inserts a line break at the end of inserted text. It also auto inserts a line break if no text is entered too.
I'm having a problem with this because the text is being saved from flash to a text file on the desktop. With every multi-line text field there's a nasty looking line break.
Any way of "turning off" this auto-line-break-at-the-end feature?
I need to replace multiple contiguous new line/line feed characters in flex with a single new line character.
Example:
The string
"My name is blah blah
My name is blah
"
Should be converted to
"My name is blah blah
My name is blah
"
Hope the example makes it easier to understand.
I am using a component to render it.
I guess using regex would be the easiest way to do this, but still it would be great if people can point me out to references/examples to get this done with ease.
I am using flex 4.5.
Basically, I have a XML file similar to:
<Main><Event><Name>Blah</Name>
<Event><Name>Blah2</Name><Event>
<Name>Blah3</Name>
...
</Event></Event></Event></Main>
Yeah, to some extent it's poor design. But the idea I'm going for is that any Event has the potential to compromise of other Events and this idea kinda loops. How to do this?
I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite loop so that the getIndex0.text is updated each time.Flex is not able to handle an infinite loop and gives a timeout error 1502. If I run the for loop until i<2000 or so it works fine.How can replace the loop so that my webservice is accessed continiously and the result is shown in getIndex0.text.This is how my application looks like:
<?xml version="1.0" encoding="utf-8"?>

I posted on Kirupa Yesterday trying to get help with a project. I've had no response because the help I need is admittedly a pain in the behind. I'm at the end of my thether here so I thought I try posting here also. I'm in the process of trying to make an "infinite scrolling tsunami accordian". Sounds sweet right.
Its supposed to grow as items are moused over along with accordion functionality. also it is supposed to wrap around the items. Ive gotten very close but I have some problems that I've hit a wall on. I've never seen a 3 in one menu like this and it'd be really cool to get it going.
So far I have the tsunami effect and the wrapping around. The only problem is that when you click on an item, instead of the items below it animating to the bottom bound of the menu and then appearing at the top when they go too far theres a big *** pause and then they just jump to wrap around position.
The accordion aspect is there too but I can't figure out how to handle the spacing when an item is expanded. I've attached a zip file containing the project in the hope that somebody might have the time to try and me flesh this out . The class in question is named infiniteTsunamiAccord.
Im using the infinite menu code from the tut.
The AS in the tut works fine in a stand-alone swf, but if you load it into another swf it wont work properly cuz it uses values like _ymouse<18
Those absolute values are not correct once the swf is loaded into a different sized movie.
What would you guys say is the best way to convert the code so that it would work when loaded?
If thought of changing every value to a target such as _root.MCinMAINmovie.CONTAINERmcFORinfiniteMENU._xm ouse>218 but this seems rather tedious... and it makes it hard to build code for something that needs to be a loaded swf and test it say before you have you main swf built.
Heres the code for the infinite menu
Code:
onClipEvent (load) {
xcenter = _root._width/2;
speed = 1/10;

I've got the very old infinite menu posted on Kirupa's site. I haven't done anything but switch it to a vertical menu, but the problem is that I put a button in the menu, the 2nd grey box, with a getURL that just goes to google. Problem is, it won't load the url. I had wanted to put buttons in this menu to get new URLs or do things it flash, but it won't respond.
View 2 RepliesI have a movie clip named "services_mc" it has 7 frames inside of it. When the movie clip gets to frame 7 I want it to go to frame 6 and play (and repeat this infinite).
I thought all I would have to do is put this in frame 7:
gotoAndPlay(6);
but it stops on frame 7.
I have a movieclip with the instance name "Ball".
I want the ball to rotate infinite, what code do i need for this?
I have an MC that is a giant text box that contains 20 different items laid out vertically, like this for example:
A
B
C
D
E
etc
I want to make the list infinitely moveable/draggable on its y position, meaning the user can drag this list up and down but the list never ends.....In other words when the user drags to the last item in the list, the list, the list starts over again. And the same works in the reverse; if the user is dragging up and gets to the first item, the last item pops up after and then goes in reverse. In other words no ending. Think The Price Is Right Wheel or the alram clock on the iPhone or iPod touch.
I am creating a space game in AS3. In order to show movement while keeping your space ship in the center of the screen I would like to move the background (in the opposite direction that the space ship is moving). I would like the background to tile so that if you ever reach the end of one background image it will place another one right next to it seamlessly. I have worked out the code to move the tiles to the right place at the right time, however whenever the tile is repositioned due to the ship reaching the edge, there is a brief period of lag.
