Closed path made with pen tool in Flash MX comprises of line segments & curved segments both.While adding anchor points on segments it is noticed that pen tool adds anchor points on curvaceous segments but not on line segments. Why is it so ? Is their any way to accomlish this task ?
View 5 Repliesi'm a novice to ActionScript but from failed Google function searches, i think i've choosen an advanced i hope possible task: how to read then apply bezier, anchor point and handle positions to different anchor points. What i need to do is precisely align a rectangular closed bezier path with a randomly shaped closed bezier path, both with the same number of anchor points.
View 9 RepliesI think I discovered a bug. Say this is a line with anchor points:
x---x---x---x---x---x---x
And this is what I want to achieve using the Delete Anchor Point Tool:
x-----------x-----------x
Then this is as far as I'm actually able to get:
x-------x---x-----------x
Because for some reason, if I delete the 2nd anchor point, the 3rd will be deleted too. I can, however, delete the 3rd without deleting the 2nd.
It is only after I've moved the 3rd further away that I'm able to delete the 2nd, but this gets tiring after a while.
I've been experiencing an intermittent issue in Flash CS5 where sometimes I can't nudge anything using the subselect tool. Sometimes I can, but most of the time I can't, and I don't know why.I can still click-and-drag points (or multiple points/paths), but I can't nudge them using the keyboard.
View 3 RepliesI'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.
I've got a flash animation of an extruding box drawn frame-by-frame for a "hand drawn" effect. The problem is that I now need to make twice as many frames to allow the box to extrude twice as far, and the canvas is too small to support this; the box would end up outside of bounds. I've tried resizing the canvas, but the extended space is at the opposite end of the canvas from where I need it. In photoshop you could chose where the added space "grew from" but I don't see that option here. Anyone knw a work around It'd be a pain in the tail to have to move very object in every frame for every layer.
View 0 RepliesI can can select the anchor points as "white" quickly, but I can't get them to be "black" without doing it layer by layer, which is tedious. What I want is way to select lines that are in different layers and get the points I selected in a way similar to the regular selection tool or free transform tool.

My question is how do you make it so that the position of the anchor points refreshes every frame? I have the basic idea I just can't quite figure it out.

I would like to design my shapes by hand in flash or illustrator, but have the final application draw them on the fly via the drawing api. The only way I can think of is to create a pen tool/drawing application in flash first, and record as you draw.
View 1 RepliesI have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
I am talking about anchor points on a line, not a keyframe. They are also called "handles". I can select the anchor points as "white" quickly, but I can't get them to be "solid"without doing it layer by layer, which is tedious. What I want is way to select lines that are in different layers and get the points I selected in a way similar to the regular selection tool or free transform tool. Here is an image of what I'm trying to do, but more easily. The lines are on separate layers, but when I select them with the subselection tool I have to go layer by layer selecting the points. I'm trying to look for a very quick way of doing it. When I do select all with the subselection tool on, the anchor points are only "white" and not "solid" as shown below.
View 8 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.
Here's the deal: I have a dynamic textbox on stage containing htmlText populated from an xml file. The text contains a hyperlink created by an anchor tag who's href attribute calls an actionscript function. When the link is rolled over and rolled out, the line break changes if the text is extremely close to the right edge of the textbox.As far as I know the problem has something to with autoSize being true and the font being embedded. I believe when you rollover the link in the htmlText, the autoSize causes the text to be redrawn and somehow this time it breaks it instead of letting it go right up to the edge of the textbox.
Originally I had solved this problem by first calculating the height of the textbox with autoSize on, then turning autoSize off and setting the height manually. As I said this worked for years but, alas, it is doing it again.Just to make sure I turned autoSize back on and practically every screen with a hyperlink did have the same problem so turning autoSize off definitely fixed it, at least 99.9% of the time.I can quick fix it by changing the width of the textbox, even 1px so that the last word of the culprit line isn't so close to the edge. However, I am wondering, has anyone ever run into this problem before? Also, it would be nice to know the actual cause of the problem rather than just using work-arounds.
I have a really basic question using the pen tool in Flash. Is there a minimum amount of segments (or something that I'm not doing) that need to be drawn in order to close a polygon shape created with the pen tool. I've found in many instances I seem to be closing the polygon and yet when I go to fill the object it won't fill. I then discover that the beginning and end points are not "joined" together (as in Illustrator).

View 1 RepliesI have a component (link to Test class) which contain one line in it, and I put one point of this line to (0, 0).
Then drag it to Flash(fla), and get its Shape in AS3 like:
// in Test.as
// assume that the movie clip only contain one line.
var line:Shape = Shape(getChildAt(0));
And I can get one point of this line which is x and y of var line. But how to get another point of this line?
Edit:
Ignore component stuff above, here has another question but I guess it pretty much the same as the question above:
Draw a line from (0, 0) to (10, 10) and draw another line from (10, 0) to (0, 10), how to get those lines of two-point form in AS3?
If I access them as Shape then I get two similar shapes which have same x, y, width and height values. Does AS3 has some way to access line as a REAL line not just a shape? or does it has any way I can calculate it out?
I want to ask how do you join two points with a line using actionscript? The points would be constantly moving.

First of all, I want to use the flash graphic api's curveTo() method. I DO NOT want to simulate a curve with hundreds of calls to lineTo() per curved line segment. It is my experience and understanding that line segments are processor heavy. Flash's quadratic bezier curve should take less CPU power. [code]...
View 3 Repliesthis is the thing: Using "lineTo" i get a line drawn on stage when dragging a mc. Then i should have four mc (note1, note2, note3, note4) added randomly over this line. I mean, the line is drawn and then over some parts of this line, using x and y of some of the points drawn there, this movie clips should be added randomly. I can make the mc appear randomly, but always in the same point (mouseX, mouseY); i cannot access others x and y of the drawn line. This is my code (noteContainer is a sprite):
Code:
private function drawingAPI(event:MouseEvent):void{
sprite1.graphics.lineTo(mouseX, mouseY);

I think it would be cool if the line started out as flat (i.e., y=_height/2 for all points) and then the y points of the line animate into place.I don't even know where to start with doing this in TweenMax/Lite... I've seen several code snippets that draw a line from left to right, but that's not what I want.

I am trying to implement contour lines in ActionScript using Conrec. I have looked at both the java and javascript implementation and am still stuck.URL...Conrec will take grid data and assemble continuous contour lines. The problem is that it does not necessarily draw those lines in a continuous fashion. For example, it will draw A->B and then C->B and then C->D instead of A, B, C, D, etc.The javascript implementation seems to be accounting for this and serializing the instructions into an array of draw points. Which is what I too want to accomplish in the end. That is it takes the instructions from the core Conrec logic (eg: A->B, C->B, C->D, etc) and organizes it into an A, B, C, D series. I think it will also return the series as a multi-dimensional array to accommodate broken lines (eg: [[A, B, C, D], [E, F, G]]). This last functionality is what I need to do in Actionscript.This last part is where I am stuck. Ignore Conrec for now (I have given up on finding an Actionscript implementation), how can I organize these instructions into a collection of serial points? When Conrec gives me "draw point from X->Y" how can I first check if X or Y are already in a series and append either X or Y (whichever is not in the series) into the series? AND if neither are in the series, start a NEW series with X, Y as the starting set. Then check subsequent instructions against all existing series and connect series if they now start and stop on the same point? Also, I need to be able to allow for a series to close itself (eg: A, B, C, A) -- a loop (is that even possible?!).
I'm not sure if there is a technical term for what I want to do beyond "concatenation". I also hope someone out there has done this with Conrec and can give me some pointers.In the meantime, I am going to continue to plug away at this and see if I can come up with something but I am not confident in my abilities.If you know another way to draw contour lines from grid data, I am open to alternatives. But I have to be able to implement it in Actionscript.
