I am struggling with an issue where I want to create a function that draws an outline of any object and I want to use this outline as curve path so I can animate objects on this path using Tweener. Like that:
Code: Select allvar path = new Array();
path.push({x:300, y:0});
path.push({x:200, y:400});

First i want to say its my first post and i've been diging straight up gold from this site and i love it and everyone out there smart enough to give out solutions.So basically am writing a game and i have bezier curve that controls where an actor moves. Am using only 3 points (start, control1, end) and everything is fine.Now i want to create a bezier curve that passes through a certain point (r1) at t = 0.5 . The problem being that i have my start point, my end point and my point (r1) at t=0.5, and i need to find the control point.
View 1 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 10 RepliesDoes anyone know a decent algorithm for drawing a anti-aliased (smooth) quadratic bezier curves in a raster?
I could simply draw them as vectors and then copy the image to a raster..
Is there any clever yet freely available algorithm to draw the curve directly to the pixels? I am currently using the algorithm implemented here:[URL].. I am doing this for learning purposes and because I am hoping it would be faster than using the copy pixels from a Shape option. Here is an example showing the none-smooth bezier is faster than the regular bezier:[URL]..
drawing out line that will serve as a mask im tryin to animate a drawing out of a line, but the line wont be an animation itself, itll be used as a mask that will reveal outline of a rectangle i'm starting right now and im on this stage so far, the problem is i dont understand why this line is not drawing out horizontally, while it should variables xpos and ypos are coordinates of the position i want to start drawing it from, xcor and ycor are the cooridnates that will be used to stop drawing once it reaches this point, then jump is how fast i want the line to draw(amount of pixels) ps:the type is there because i will also make another case for vertical line.
Code:
lineDraw = function(type, xpos, ypos, xcor, ycor, jump){
this.createEmptyMovieClip("temp", this.getNextHighestDepth());
this.temp.lineStyle(5, 0x003300,100);

I want to have a different coloured stroke (outline) used on the pie wedge under the mouse from the outline used on the other wedges.
The PieSeriesItem referenced by the mouseover event doesn't have a stroke parameter, and it looks like it is an all or nothing deal with the outline colour on the whole pie.
Is there any way of specifying the stroke parameter on a specific wedge?
I'm on the user have to be able to draw/trace outlines of different shapes. So for example an "S" shape is on the screen, and the user needs to try to draw OVER that shape. So it's not just mouse recognition, it has to see if the user draw over that shape good enough. So it's kind of like a colorbook but you only draw the outline of the shape, if you know what I mean.
I've been searching the web and haven't found any pre made solution for this, but I thought that before I try to make it all from scratch I could ask you guys here about it.
i'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 just starting out with AS3, so I'm trying my hand as some of the more basic drawing functions, to try and get a handle on them. The problem I've hit is using 'curveTo' to create a smooth curve is creating some very poor aliasing results. Here is an example: [URL]
The first part (which is actually on the right) is a very simple curve from 50,50 to 100,100, through 100,50. I would have expected the end points of the line to be single pixel width, but it's aliased over two pixels.
The second part (on the left) shows why this is a problem for me. I'm trying to draw a basic shape outline with a semi-circle at the top, but it really doesn't look great (it looks shifted half a pixel to the left relative to the rest of the shape).

View 2 RepliesI'm projecting some vectors using the Utils3D.projectVectors() method. This gives me the (x,y) screen points. Then I'm using graphics.drawGraphicsData(); to draw a GraphicsTrianglePath containing these points.
The points are drawn at the top left (0,0) of the stage, but I want them to be at the middle (275,200). I know there are several ways of doing this, like for instance, adding 275 to all the screen points x values, and adding 200 to the y values, but I think that would be a massive operation.I can also set the sprite containers x and y, but I want its position to stay in the top left.
Simple way of drawing it in the middle?
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 3 RepliesI'm having issues with drawing a circle. The code seems to work for drawing all the required segments except one, but tracing the points of the drawing looks correct.This is the class that generates the segments:

I'm attempting to make a curve drawing tool a bit easier to use.Rather than drawing a basic curve and then clicking on the control point to change it, I would like the user to be able to click on the curve itself to change it, much as you do in the FlashIDE.So, given start and end points, and a point on the curve, how do you determine the control point for use with the MX API?(I googled this, but found mostly info on cubic rather than quadratic curves)

I am facing a real nightmare. I have many Assets which use strange origin points. I need to essentially draw these assets to a BitmapData, but the origin point causes all kinds of problems. StackOVerflow does not let me attach an image so I will try to describe. Imagine you have the shape of a digit "8". You have 3 of these shapes.... Each shape has a different origin:
1) The middle of the "8" shape
2) The centre of the top "o" part of the "8" shape
3) The centre of the bottom "o" part of the "8" shape
How, with a single drawing routine, can I correctly draw each of these instances to a BitmapData? Ideally I want to find the top left part of any Sprite bounding box, and bitmapdata.draw() from there. But after 2 days, all of my attempts either get clipped.... or using matrices, they do not work for every origin point and different drawings get clipped in different locations.

However, I can't seem to figure out how to project the two side points. I've tried drawing a bunch of different triangles to figure out how to project the points, but I can't get it to work

View 2 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.
