Finding the intersection point of 2 line segments is easy enough.
But now I need to test wether a line with thickness intersects another (non-thick) line.
My idea is to actually perform 2 tests, one at the top and bottom of the thickness of the line. Does that make sense? Is there a better way to do it? I dont need the intersection point, just a boolean yes or no.
I'm trying to improve upon the hitTest() function.I have a game in development that involves square robots, rectangular wall shapes, and line segment shots rotating and moving around. Without the rotation, hitTest works fine, but with rotation, problems arise.Walls at rotation 0,and square robots work fine. There is a small amount of funkyness with a rotated robot by a wall corner, but it's not very noticable.The big issue is collision of two rotated square robots.
I can create a function to get the line segments that make up each robot, and the check to see if any intersect. This will mean finding the location of eight points (using height and width and some trig to deal with rotation), finding the slope of eight lines, and then testing lines for intersection up to 16 times. This would be needed to find the intersection of each pair of robots. Those are worst case numbers, some colisions can be detected or ruled out before getting that far in the algorithm, but this check would need to be run every frame against all robots and walls and shots (shots could be a single line segment, though)Right now I'm talking about 8 robots max, maybe 6-20 walls, maybe 5-80 shots on screen @ 30 frames a second.
This is easy enough to create, but before I spend a day coding it all, I'm wondering if the computation requirements are going to make it prohibitive.(If so, I'll probably have to switch to circular robots).I feel like there should be a simple formula to find if two rectangles on a cartesian plane intersect, but I can't find one.
There is some information but I couldn't figure it out:How can I detect if a line intersects with a triangle ? And how can I detect the point of intersection in AS3 ?

I'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 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.

import flash.display.BitmapData;

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.
I am developing a white board application which allows the user to draw line with arrow head (some like Microsoft Word line with arrow feature). I am using graphics property along with lineTo() method to draw a line. Now i have to draw a angular arrow on the last point of line. I am drawing the arrow by connecting the points around last points. As 360 line can pass through this point and each line can have a different angle of arrow.

I need to read a large CSV file (8-15 MB) and generate a LineChart in Flex AIR. Since Chart need data in structurd format like XML. When I read CSV and convert it to XML object 8 MB file size become 24 MB XML object and not able to graph.
Best solution is to read Line by line and read only part of data. How can I acheive this in Flex AIR ? Is it possible to read line by line in Flex.
Otherwise what are the best ways to draw a graph in FLEX using large data.

View 4 RepliesI have three MCs in a proximty menu (ie when the mouse is close they go to the mouses position and follow it).

This maybe a bad explanation so here is a link to back it up...

I'm making a very simple game that lets you draw a curve by hand (using lineTo to the mouse position on mousemove) but now, I need to check wether the line intersects wiith another part of the same line (e.g. a loop)
I first used an onrollover command, and that worked, but not always because the mouse moved too fast (same with hittest with mouse). Then I pre-drawed the line in another mc, used hittest on it, and if it wasn't intersecting, draw it in the real mc. But that didn't work because it used the bounds to test. I guess the best way is to use some mathematical formula, but that would mean I have to save all my coordinates in an array..

View 2 RepliesI've managed to follow some drawing tutorias which work fine (mouse down draws a line everywhere you move mouse like MS paint).I would like to adapt this now if I can so that when a user clicks down, a straight line will follow their mouse until they click again and this releases the straight line. This should leave one line on the screen, then they are free to move their mouse and repeat the action again.

View 5 RepliesMy issue is that for my website I want there to be movies in between the interactive parts of it where the interfaces slide in and out. However, I can't stop a movie from playing over and over instead of playing once and going to the next frame.With 2.0 I haven't been able to find any research that helps me, probably because I don't know the correct keywords to search for.Right now I have my main time line set up with a loading bar on frames 1 & 2, that then jumps to frame 3 where I have embedded a movie (Instance named: mc_start) of the interface sliding in. Preferably after that I need it to jump to frame 4 where the actual interface is.
I can get the movie to end by going into the embedded movie's time line and simply have stop() ; at the final frame, but I can't get it to go to frame 4 on the main time line. If I having something like gotoAndPlay(4) ; on the final frame of the embedded movie's time line, it simply goes to frame 4 of the embedded time line and not frame 4 of the main time line. If there was a command to make it jump back to the main time line instead of the embedded time line, that would work perfectly.Coding on Frame 3 of the main time line to jump to Frame 4 would work if I knew the correct language to detect when the movie has ended (Movie is 191 frames long), so that afterwards it would immediately jump to Frame 4, but I haven't been able to find any resources that will teach me how to do it. Right now having gotoAndPlay(4) ; on Frame 3 of the main time line obviously makes it immediately skip the movie on Frame 3 and jump to Frame 4.
What I have is a movieclip and a button in scene 1 (which is the main timeline).There is an actionscript layer also on the main timeline. what I want to do is when I click the button, it would do a nextFrame(); in the movieclip timeline instead of the main timeline.
