View 6 RepliesHow to manipulate shapes with anchor points at run time?
View 6 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'm working on an application where I'm drawing some rectangles on the screen, and then will need to manipulate the shapes (change their size, location). I tried to do something with .drawRect and clearing the shape each time I was manipulating it, but the RAM usage was spiking and then falling (presumeably because i keep reinitializing a new component and then removing it, and garbage collection was cleaning it out). This seems like its probably not the most efficient way to do it.
Is there a way for me to just create a shape once, and then move it around on a canvas (and change its width and height without all this RAM usage?
I 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.
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'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.
View 2 RepliesI'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 always see these bezier curve things where you can like choose how to make the line bend and everything and today i started expirimenting with the drawing API and found out that it's incredibly easy to do. 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.
View 7 RepliesHow can I translate bezier pen anchor and control Points into drawing API code? 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 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 RepliesSay User uploads a front facing photo. I give co-ordinates. I want to give user facility to move the points to match eyes and lips on their uploaded photo. So I want to get the editable shape. I think we will need to use bezier curves for this. How can I modify my code to line through the bezier control points?

Is it possible to get the time of one of my navigation cue points. I am using the NetStream class and want to seek to it, but just realized that I can only do that if I have the time for it. Is that possible?
View 12 RepliesI have a question about shapes (i mean the flash.display.Shape class). Is it possible to import Shapes directly from the library as Shapes and not as Sprites/MovieClips? Shapes are supposed to be faster than MovieClips/Sprites, right? So why is it only possible to import MCs/Sprites from the library? I understand that generally shapes could be created solely by actionscript, but in my case the shape comprises of many points and is curved - so it's quite infeasible.
Is there maybe some sort of plugin to generate code that would draw the desired shape from a drawn shape in CS4? And a last one: Are there any benchmarks out there for performance comparison between sprites/mcs/shapes? How much performance do i loose by using a sprite instead of a shape?
Is there an actionscript for a point system? I want my points to be time based from this script
stop();
count = 60;
countdown = function(){count--;
if (count ==0){clearInterval(doCountdown);
gotoAndStop(11);
clearInterval(doCountdown);
}}doCountdown = setInterval(countdown, 1000);
I am trying to draw a continuous curved line in flash. There are many methods but none of the ones I have found so far quite fit my requirements. 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 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 having trouble manipulating instances of xml loaded pictures. I want to change their x and y position and tween them etc. I have loaded them onto the stage from an xml file, and given them all individual names but the most I can do now is either move them all together, spread them evenly on an x or y axis, or remove one of them using getChildByName. What I can't do is what I want to do, which is place 20 or so images in an exact place, ie. a square.My main difficulty seems to be that I don't know how to reference an individual xml node and move it.

View 9 RepliesI am using anchor labels for a new site and it works good in firefox but in IE it is going though each anchor till it finds the correct one. You can see it going through the labels in the address bar and a clicking noise for each one, besides the fact its ugly it takes a while to go through them all. You can see it here -[URL]

View 3 RepliesI'm using AS 3.0, and I'm trying to change the frames inside a specific object's timeline.The change will be triggered by keyboard events, but I don't know whether to add the eventlistener to the stage or to this. Also, it doesn't seem to be responding to anytime I use a gotoAndStart() or gotoAndStop() it just ignores it completely. Is it calling the stage's timeline when I call this? It also doesn't help when i add this.gotoAndStart() or this.gotoAndStop(), so how do you change the frames outside of the main timeline?
View 3 RepliesI have a flash map of the UK which is divided up into the counties, a user clicks on a county and is then directed to a new url, eg. [url].... The flash map remains on that new page in case they wish to select a new region.
What I want to know: is it possible to manipulate the flash so that if the [url]...then london remains highlighted on the flash map. I presume I will have to use some AS which is fine as long as it is AS3.
I'm trying to manually dispatch events on a textfield so I can manipulate it indirectly via code (e.g. place cursor at a given set of x/y coordinates). However, my events seem to have no effect.
I've written a test to experiment with this phenomenon:
package sandbox {
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.text.TextField;
[Code].....
As we can see, the events are being captured and replayed successfully. However, no change occurs in tf2 - the mouse cursor does not appear in tf2 as we would expect. In fact, the cursor remains in tf even after the tf2 events are dispatched.
What are the inbuilt functions available in flex,actionscript that I can use to find a node with a specific name inside xml variable and what functions could help me manipulate it? Something like Xquery in SQL! I dont want to use for loop everytime I want to manipulate a xml variable. For example, if I want to "cut" node inside this xml and add another attribute to it named enabled pro grammatically. Or how could I find "Find Next" node and delete it?
<menuitem label="Edit">
<m label="Cut"/>
<m label="Copy"/>
<m label="Paste"/>
