ActionScript 3.0 :: Allow Vector Drawing In .swf??
Nov 29, 2011
I have seen flash games where the player can actually draw objects. Meaning they have like a pen cursor in the game, and they can just start creating vector art. I have a game in mind where it might be a cool feature to have the user draw a few things. I bet this is a heavy subject so I am not asking for every bit of code I'd need to create something like this, but I have searched quite a lot for anything remotely brushing on this subject and clearly I have no idea what I should be punching into google.

I have a Sprite that I draw into using lineTo. Later the sprite is drawn into a bitmap to add to a mask. That works great. The issue is erasing the vectors in the Sprite once they are drawn.
To draw I just do something like:
userDrawing.graphics.lineStyle(12,0x000000,1);
userDrawing.graphics.lineTo(mouseX,mouseY)

I want to create a game which uses a very basic font which is a single-pixel wide regardless of font size (similar to the font in classic Atari games such as Asteroids & Battlezone).Many, many, many years ago I had a programme on the BBC Micro (yeah, that many years ago) which drew letters, to whatever scale you wanted, as vector art. I was wondering whether anyone was aware of a similar library for Flash (or, alternatively, of an appropriate font which always scales to single-pixel width).

I'm getting
ActionScript Code:
1067: Implicit coercion of a value of type
__AS3__.vec:Vector.ie.aro.floorplanviewer.model.buildingVOs:ConfigurationVO>[code]....
which surprises me as ConfigurationVO inherits from NodeVO.Is the compiler really not able to figure out that a Vector of a superclass should be able to hold a reference to a Vector of a subclass?

Created Vector with the initial length of 100.
var v:Vector. = new Vector.(100);
v[90] = "Ninety"
v[190] ="oneninety" //RangeError: Error #1125: The index 110 is out of range 100.
//How to change the length from 100 to 200 to store a value at index 190

I am currently being confused by the Vector class.I wrote a beautiful XML to TypedClass parser. Works beautifully and without fault. UNTIL a co-worker noticed we got a Conversion Error for Vector.<Number> to Vector.<*>.
Every Vector I've ever tested all extend Vector.<*>.
Vector.<Sprite>, Vector.<String>, Vector.<Point>, Vector.<Boolean>, Vector.<TextField>, Vector.<CustomObject>, etc etc etc. ALL of them.
<type name="__AS3__.vec::Vector.<String>" base="__AS3__.vec::Vector.<*>" isDynamic="true" isFinal="false" isStatic="false">
<extendsClass type="__AS3__.vec::Vector.<*>"/>
[code]...
But then when I use describeType on Vector.<Number>, Vector.<uint> and Vector.<int>.
<type name="__AS3__.vec::Vector.<Number>" base="Object" isDynamic="true" isFinal="true" isStatic="false">
<extendsClass type="Object"/>
<constructor>
[code]....
Now I have accounted for these 3 vectors individually as even uint and int does not extend Vector.<Number> as I would have expected.
And my parsing function works for all types correctly again. But my confusion comes as to WHY this is the case, and why I couldn't find any documentation on the subject.

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.

I cannot get this to work. Without the "var drawing", "var drawing being true or false" and the "if statement", it works fine. But I need to add the "var drawing" so that you can only draw if you turn it on by pressing the "draw_btn" button. Note, I do not get an error, the script "apparently" contains no errors. Here is the code:
ActionScript Code:
var drawing = false
_root.createEmptyMovieClip("myLine", 0);

I've created a drawing tool which allows the user to draw on the canvas, the problem is that if I try to draw over a movieclip nothing happens. Is there a way I can allow for the user to draw over movieclips? For example if I had a background of paper?
Here's the code I'm using for it:
// This code is for drawing the lines on the page
//1.
var drawingLine:MovieClip = new MovieClip();
addChildAt(drawingLine,0);

I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?

I need to draw on stage about 40,000 4x4 squares each a different color. The color is determined by an xml file. I have this working in as2 and have converted it to as3 the problem is the amount of time it takes to draw is causing cs4 to time out. I have extended the script time out to 60 seconds. In cs3 as2 it would draw the squares in about 15 seconds. I was hoping as3 cs4 would improve performance but seems to be the opposite. I have tried several methods such as adding children and various drawing variations. the bellow seems to work the best, but is still causing flash to crash.
ActionScript Code:
import flash.display.DisplayObject;
import flash.display.Graphics;
import flash.display.Shape;

I have a simple landing page that im making for a website.The title to the site. Just plain simple static text but its just always edgy and aliased? I even tried making it orginally in a very large font size breaking it up and then reducing it in size. Still no luck.But when i zoom in using the right click menu its starts sharpening up and in real close-up seems razor sharp. But when the page is displayed at 100% size the text which is now much smaller is aliased.

The great thing about vectors is the data typing / autoComplete.. The thing about them that I hate is the numeric index and the resource intensive retrieval methods you need to pull an element.
so with objects:
myObject["myObjectKey"]
is great, fast, etc. BUT there's no data typing myVector[0].myProperty is fantastic for auto complete, but there's no quick index, instead a bunch of for loop logic that can get really messy in more complicated data models where there are a lot of relationships. Does anybody know of an elegant hybrid solution aside from things like
var myProperty:MyFavoriteDataModel = myObject["myProperty"] as MyFavoriteDataModel;

I've imported a vector graphic from AI into my stage. When I click on the vector graphic that's been converted to movie clip symbol and drill down to the vector level, as soon as I insert a keyframe in the timeline, I no longer can use an eraser to edit the vector graphic. It automatically move up one level as soon as I insert a keyframe. Does anyone have any idea why I'm getting this behavior? I want to create a hand written effect with this vector grachic.If I draw a vector square on the stage, convert to movie cli, double double click the movie and then I am able to edit or change the vector shap but that's not the case with the imported AI file.

I am trying to use the new Vector class introduced in Flash 10. Tried compiling the code using mxmlc but am getting this error message:
Error: Type was not found or was not a compile-time constant: Vector.
public var selectedRoutes:Vector.<Route>;
What is the general consensus about the viability of using this feature? Can you do introspection of the Vector with describeType and get the type the Vector contains at runtime?

Why would bitmap outperform vector?My Flash is for a large Kiosk, with rich media requirements and must function accurately as a counter. I want to keep everything vector for scalability. When I did a simple FPS test, I noticed my Bitmap version performed perfectly, and the all vector file was noticeably slower.
- only text and bitmap perform well, not vector
- background and clouds OK, but more layers slow it down

I'm looking to build a website that has a flash interface and allows visitors to upload vector art in a number of file formats such as SVG, EPS and AI.
I have two rather large problems...
1) I need to load the original vector art, probably convert it to FLV and display it in my flash application.
2) After the user potentially loads a number of images, adds some text, rotates or transforms some elements, I need to save the resulting composition into a vector art format that I can print.
I'm not much of an AS developer...my experience is mostly in .NET/C# & C++. I'm looking for a good library or API that provides the functionality I will need to convert different image formats and save the results. How much of this can be done using Flash / AS...? How much in C#...?

im trying to recreate the swf on that page only then in AS 3.0 I'm halfway there but i cant seem to draw the correct line on the normals of the main vector. from point0 to point1 would be vector 1, and from point0 to point2 would be vector 2. Vector2 has been drawn with the normals to its sides. (the blue cross)Vector 1 has also been drawn, its the black line thats running to the green ball.Im trying to visualize the forces of vector1 on vector2. just run the code and you'll see what i mean:
ActionScript Code:
//canvas
var canvas:Sprite = new Sprite();
var point0:Sprite = new Sprite();
var gr0:Graphics=point0.graphics;

I'm making a game based on pong. At the start of a round, the ball will go in a random direction and when the ball hits a paddle the ball will move in a certain direction depending where it hit the paddle. The more centralized the hit is, the more straight the bounce is. Here's the tricky bit: the ball may hit either a vertical or horizontal paddle and I want the xspeed(horizontal movement) or yspeed(vertical movement) of the ball to increase/decrease in proportion to the opposite speed while keeping the same general speed of the ball(it can decrease and increase). Here's an example(you might want to get a pen/pencil and a piece of paper):
Let's say the ball is moving at 45 degrees(so it's going downward right) and hits a horizontal paddle smack dab in the middle, thus it goes at 270 degrees(straight up). So, at first the xspeed and yspeed are both the same, then the xspeed is zero and the yspeed is at the max(to the general speed).However, let's say that the ball hits the same paddle but at the edge(either edge will do the same) thus making the ball go at a near 360 degree angle, making the xspeed near max and yspeed almost zero. Like I said, I want the two speeds to increase/decrease in proportion to the general speed, this is so that xspeed or the yspeed don't exceed the general speed.

I have made a webpage that scales to the size of the users screen. Now i'm having to following problem. There is a image gallery in this website that makes use of an XML file. Everytime when the website is scaled to a bigger size the image gets unsharp. This only happens to the external image that is displayed in the gallery since the flash elements are all vectors.I was already thinking about a higher DPI rate or using different images.
