ActionScript 3.0 :: Dynamic Line Drawing From Object Locations?
Jul 1, 2010
I'm creating a flash based dynamic electrical circuit board and have come across a problem. I have a function that is a fired from ENTER_FRAME event that loops though an array where each element contains the following:
To Clarify - A line should be drawn from ChildObject1 to ChildObject2 in the saved colour. The above is a string. I slice at each '#', which is working. Each object gets added through my created toolbox so added dynamically.I can get the DisplayOBject of the parents by using - var obj1:displayObject = getChildByName(sliced[1]);
But cannot do the same for the Child object by - var subobj1:displayObject = obj1.getChildByName(sliced[2]);The reason for this is that each parent can be dragged so I would like the drawn line to move with the children.how to find the child objects
I have a line drawing that I have to animate it has curved lines like the image attached.I have tried tweening however it looks terrible and not smooth in it drawing.this is the action script I already have so far.
createEmptyMovieClip ("curveLine", 1); with (curveLine) { lineStyle (2,0xffffff, 600);[code].....
I'm trying to have the user draw a line on the top layer of my scene. I've been able to get my line, but it always shows up behind everything else. Here's the code I'm using: Code: mouseOld = mouseNew; clear(); if (isMouseDown) { mouseNew = true; if (mouseNew != mouseOld){ drawStartx = _xmouse; drawStarty = _ymouse} [Code] ..... The code works fine, but how would I get my line to show up in front of everything else?
I have a movieclip containing a vector drawing, can I dynamically change the color of the fill and line in AS2, or do I need to use setRGB and divide the movieclip?
Right now I can create a straight line from mouse down to mouse up. What I can't quite get is a preview of that line. does anyone know of a simple way to show a preview of the line while the mouse is still down and the user is moving the mouse?
What I have now: Code: var clip:Shape = new Shape(); addChild(clip); stage.addEventListener(MouseEvent.MOUSE_DOWN, startLine); stage.addEventListener(MouseEvent.MOUSE_UP, drawLine); function startLine(evt:MouseEvent) { clip.graphics.moveTo(mouseX, mouseY); } function drawLine(evt:MouseEvent) { clip.graphics.lineTo(mouseX, mouseY); clip.graphics.lineStyle(1, 0xff9933); }
i am trying to take photos using webcamera from online web application and i got sample code from [URL] It is working fine to take photos online with the attached web camera and saving it into server for future purpose. Here my problem is i want to keep horizontal and vertical lines on top of the camera area but what ever line i am placing all displaying behind the video area and camera area is displaying ontop of all layers.
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.
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 want to set different locations in an Image, and when I mouse over the location it needs to shows something('box' or 'x' nd 'y' position of the location). How can i achieve this.?
I need to move a movie from let's say '_root' and put it into '_root.source.pages.ph' on level 0 in the current state that it is in....is there anyway you can do this using actionScript? DuplicateMovie starts the movie over at frame one and doesn't delete the old movie and swapDepths require the movie to have the same parent.
Basically I've got a reasonably complex drawing object in a fla and I want to reproduce it in a class definition using the drawing api. However obviously this is a tedious task, so is there some trick or automated method of doing this?
Last time I needed to do this it was a drawing of an arrow and I ended up writing down x,y,width,height values for everything but this one has curves in it which I don't have experience with drawing anyway.
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?
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:
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.
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); function moveguard(event)
I was looking for tutorials on drawing in flash using actionscript and all of the tutorials I found showed how to create content instantly (with the click of a button etc).But I was wondering if it was possible to use actionscript to draw a line from coordinate A to B over, say 12 frames?
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).
right now i can create a straight line from mouse down to mouse up. what i cant quite get is a preview of that line. does anyone know of a simple way to show a preview of the line while the mouse is still down and the user is moving the mouse?what i have now:
Code: var clip:Shape = new Shape(); addChild(clip);[code]......
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.
I'm trying to make a short script in AS3 which will simply take some animated lines that are in a movieclip (pre-animated in library) and draw a 15px diameter circle around each vertex / point of the lines.
how to access the vertices of the lines in actionscript!
