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.
View 6 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'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'm trying to animate a line by drawing using tweenmax and lineTo, but flash seems a little confused about the coordinates of things. The lines are also drawn a little shaky. Here's my code:
var childArray:Array = new Array(sC0,sC1,sC2,sC3);
var curChild = 0;
function drawLines(){

I want to create line between 2 points ...such tht the line will start when i click the point A then i will drag the line by holding it to point B and i will join the line to point B by clickin on point B (somethin like the pen tool) ..then line will then be joined between the points ...
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.

View 1 RepliesI 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 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 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.
I have a large-ish array of points.
The graphics object I am using has it's alpha value set to 0.1.
When these points are plotted iteratively, and the line being drawn overlaps another line drawn earlier, there is no visible change in the colour at the intersection.
If I draw the line differently, not using an array of points, the alpha is not ignored.
ActionScript Code:
public function render(e:Event):void
{
if (segmentsCollection.length > 0)
[Code].....
This all occurs on each ENTER_FRAME event until the array is emptied.
I have tried loads of options but the alpha is always ignored.
Is there a way to plot multiple data for the same value x? For example following points:
[1, 1], [1, 2], [1, 3], [2, 6], [2, 9], [3, 11], [4, 11]...
When you make this draggable and droppable, the object automatically jumps to the cursor of the mouse, but at the location set at (0, 0)? Well, is there a way to counteract this, so if the mouse is over it and you click it you can still move it but the object will stay where it is relative to the mouse cursor?

View 5 Repliesadd multiple instances of an object to the stage at different but not random points.
For example - I have a box that is linked to a class file. In the class file I have an "ADDED_TO_STAGE" event listener. The function that is called places the box at a certain position on the stage say.... x=100, y= 200.
In the document class I create an instance of it like so -
_box:box = new box();
addChild(_box);
Now what I want is to create multiple instances of box on the stage every 5 seconds. But I don't want them all to spawn at (100,200) on the stage. But here's the catch, I don't want them to be random spawns either.
for ex- I want the first instance of box to spawn on (100,200), then 5 seconds later, the second instance to spawn at (200, 800), the third at (100, 500) and so on.
Would it be possible for me to create objects on the stage to serve as reference points for where i want the instances to spawn instead of writing the exact co-ordinates?
