Actionscript 3 :: Drawing An Arrow At The End Point Of The Line Using Line Slope?
Jan 9, 2012
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'm trying to create a simple graph showing the stock trends for the past few days. In the x axis I have the dates and in the y axis I have the stock value. I have to do this dynamically and I think I can figure it out, but I need help with something else: I need to be able to (dynamically) draw the slope of the line as the user clicks on a point... something like in www_calculusapplets_com/twicediff.html except that instead of having the slider the user will click on the actual line.

Im using the drawing API to draw lines between movie clips, join the dots style, but is there a way to draw an arrow in the centre of the line indicating which direction its going? I know it will involve trig i think and i guess it will be something like (1 find the mid point of the line (2 find the direction by checking the start point and end point (3 draw a triangle somehow that goes in the right spot. It shouldnt be too hard if u know your trig i bet...

Lets say I have two objects, and I want to use action script to draw a line connecting them, which will update automatically as they are moved/ dragged.Can anyone show me how to do that, and also how to control line's parameters like colour, weight etc?

is it possible to somehow use a the clear() function on a line that has been dynamically drawn only at a certain point? i need a line to be drawn and then gradually erased with time. currently i'm drawing a green line and then a few seconds later, a start up a function that creates a white line above it. it works great if this line is above a white background, but if it's above some other element, you see a white line.

Any way to get a curved line to draw from a known point a to a known point b. Point b will always be changing and will be in any position around point a. I can work with an existing line from a movieclip and change it somehow, but right now I can't find any way to accomplish it.

I've been unable to find info on this because it's tricky to find the correct keywords. I want to allow the user to draw a line so that the application can measure the distance between two points chosen by the user. I could let the user click on one point and then the other but it would be much better if, after clicking the first point, a line would follow the mouse cursor like in most graphic applications. How would you do that? Is there a convenient method for that? Maybe use the MOUSE_MOVE event after the MOUSE_CLICK and continuously draw a 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.
Class File (DrawingArea):
package
{
import flash.display.BitmapData;
import flash.events.Event;
import flash.events.MouseEvent;

At the moment I am using two mini objects within the line to calculate the slope of the line I have.
I was wondering if there was some easy function within as3 to find the slope of a line that had been drawn out, if not... I suppose I have my own theories on how to do it, such as checking for hit tests in a circle until I find the line.

Im building a pretty simple drawing board in flash, i got this code from this forum and it works fine (there is more to it but this is the drawing part)[code]This works fine. But i want to be able to erase the drawings, step by step this is ths tricky part, ive looked everywhere(ok not everywhere) but in a whole lot of places but the only thing i found is how i could delete everything with removeChild and that in not what i want. Maybe i need to change the function abowe? Please help me to get in the right direction. What should i read about /look at?

I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.

How do i animate a drawing line? I mean like from point A to point B, the flash will show it is "drawn" itself.Can I do it simply without actionscript? Is it possible? Because I have many lines to draw, to make it into a diamond.

What I'd like is the ability to draw a line with the drawing tools in Flash, and have that line appear onscreen as if it were being drawn. I don't think there's a way to do that with the animation tools (I'd like to give it a go, but I have no idea, once I've drawn a line and converted it into a symbol, how I could access the anchor points and whatnot of said line to then do some funky stuff with curveTo, or whatever better solution is out there...

With several flashes I'm trying to create, I find that I need to know how to depict a line being drawn or a plant/vine growing (same concept right). Obviously frame-by-frame animation can be used, but that's quite tedious. There must be some other, more productive way to pull it off. Example of the vine: [URL] I've tried shape tweens with shape hints but it didn't render very well at all.

I'm having troubles with the width of a line using the lineTo and lineStyle function, I can put setting the thickness and noScale parameters, and it works fine for no longer lines than 32000 pixels, but when I try longer line, the thickness changes to a bigger width. if you want to try what I'm saying you can prove this by changing the num variable:to 33000 for example:
num = 32000
this.createEmptyMovieClip ("Envolvente", 100);
this.Envolvente.lineStyle(0,0x00CC00,100, false, "none",
"round", "miter", 0.8);

i'm developing a game for mobile devices where I need to draw many objects and some lines(1~3 just occasionally).
my problem in short is: Line drawing is too slow for iPhone4
objects are drawn with bitmap, so it's pretty fast with GPU support. drawing lines are slow.
a end point of a line follows mouse cursor, so it changes every frame.
here's how i did it
initialization step:
var img:Shape = new Shape();
addChild( img );
[Code]....
that gives me 47~48 FPS on my iPhone. +2 FPS but still way too slow for a simple line.
without the line, i can maintain my whole game around 30 FPS. with the line, it goes below 20.

I was told that by using actionscript to animate, it will make the flash file smaller and animations smoother... is this a correct assumption?
with this in mind, I have the code:
ActionScript Code:
this.createEmptyMovieClip("myLine", 10);
myLine.lineStyle(2, 0x000000, 100);
myLine.moveTo(10, 10);

I am having some trouble drawing a line between two movieclips. One of the movieclips is moved with the arrow keys. The line is created between them, but every time the movieclip moved another line is created. I would like only one line to connect the two movieclips. I am trying to create some sort of "AI." When the line hits a wall, then there isn't a clear line of sight. Here is the code:
ActionScript Code:
stage.addEventListener(Event.ENTER_FRAME, moveguard);

Drawing a simple line is easy - here's some sample code here from Kirupa:
[Code]....
My First Question is - how can you get it to show the drawing of the line - almost like an animation? This example instantly shows the line - I want the appearance that you're watching the line being drawn. Do you animate the lineTo variable and just keep refreshing? My Second Question is - can you do the same with a Bezier curve? In the end, I'm trying to draw random bezier lines from the left to the right in varying thicknesses and shapes (being able to see them being drawn from left to right).

I've followed the drawing api tutorial off here for MX and have got that working perfectly. I would like to adapt this now if I can so that when a user clicks a straight line will follow their mouse until they click again and this releases the straight line.
