how draw sine and other functions using the drawing api ? so far all my efforts have yielded amazing random designs but not the desired functions.
View 5 RepliesI made this one poor class that has a public function which draws with a single loop a shape with curveTo() function (I tested one option to draw straight lines with lineTo() and only curved lines with curveTo() function but in my opinion, that lineTo function where a bit slower, at least in my implementations of testin speeds).I sent to it four parameters (anchor points and the control points) as many times as there were some corners to draw and everything seemed to go well untill I checked which way is faster to draw single rounded rect. Flashs own way beats my version up with huge 120 m/s distance already in some 100 000 iterations. The format of data I tested to send to my class function to draw that goddamned thing were numbers in arrays, numbers in objects and numbers in my own class objects like linked list and the file that holds just four numbers included in arrays or linked list. And two separate arrays, one for anchor points and one for the control points, with just Point Objects were fastest (if I remember correct) way but still that 120 m/s slower than Drawing API in Flash.My function in the class where something like:
ActionScript Code:
public function drawShape(points1:Array, points2:Array, lineOn:Boolean = false, fillOn:boolean = false, lineThickness:Number = 1, lineColor:uint = 0, lineAlpha:Number = 1, fillColor:uint = 0xff, fillAlpha:Number = 1):void{[code]..........
How can I draw only in a particular mc using drawing API...
View 4 RepliesI've been working a flash drawing application with an undo button function so you can delete the last line you drew. Everything is working ok except when I use the clear_btn removeMovieClip(shapes[sc]); deletes all the lines so far but afterwards you are unable to draw again[code]....

View 0 RepliesThis code is from a drawing board, the problem is:
1- When you click outside the drawing area, a dot is drawn (thus you cant click anything except inside drawing area because it will result in undesired dots)
2- When you drag outside the drawing area the dot is drawn (bad), the pencil doesn't draw (good), but if you drag until reaching the drawing area draws (undesired, because it should only draw when you started to drag from inside the drawing area) how to tweak the code or simple add a "deselect" tool option ? That's a link to the fla file ziped, and that's the code of the drawing board: [URL]
Code:
_root.P = 0;
_root.level = 1000;
_root.tmpx = -1;

i'm working on a class project that allows people to draw on a square, save it, display it for others to see, and then lets anyone to continue drawing on that square.how do i script that? i need to use flash and AS2.0, and i'm trying to do some research on how to do this whole thing, and i'm hearing a lot of things: some say xml, some with php and mysql? whatever it is, i believe this has to be a server-side thing? i don't mind learning light scripting of other languages, but the primary scripting should be AS, since it's a flash class.i'm not sure if this is true, but i think xml, php, and mysql are only text-based? for my project, i imagine that people would be saving an swf and then loading that swf and continue adding. is there a script in AS that generates an swf? maybe jpg is fine too. i just need to be able to save and load something that's image based and not text-based.

how to turn that "Drawing Object" thing off! I cant even fill it in! (the thing i draw) Im using Flash Pro CS5
View 1 Repliesim new to this forum and kinda new to flash and php together...i have this project that would load a swf movie on a drawing board and user could draw something over then swf movie. It should be able to save the drawings to the database, so that the user could just load it for later use. for example if the user draws a zigzag line at frame 5 of swf movie and on frame 10 of the swf movie deletes the zigzag line and draw a circle and then saves it. then loads it later, from frame 1 to 4 of the swf movie the zigzag line should not show but on frame 5 to frame 9 it would show and on frame 10 shows only the circle. or just on the specific frame number of the swf movie it will show. like when user draw on frame 6 then on before or after frame 6 it wont show..the second one might be a bit easier to implement.
how do i save the user drawings over the swf movie? and how do i load it? do i have to save everthing (like x and y coordinates, movieclip names) in a textfile? and use that textfile to recreate the swf file drawn? what ways could i implemnt this? hopefully someone to could point me in the right direction.
I was screwing around one day and thought I'd make a little line-drawing-thing. Basically it just attaches movie clips and draws lines between them using the drawing API. That was the easier part. Now I though I'd take it a step further and add some curves. I tried but the attached file is the best I could think of.
square.fla is the original file
lineCurve.fla is the file in which I tried to add curves.
I need to know how to script the drawing board as in the user can only draw on a specified area. For example, on a 800x600 layout, only 1/4 of it is the drawing board.After the user has drawn the image, when he/she clicks on a button, the image will be replicated on another area in the same 800x600 space. So far, I can only manage to make a drawing board on the whole 800x600 space and erasing.
View 2 RepliesI need to to incorporate a functionality where the user can use his mouse to draw a rectangle by dragging his mouse over the canvas - much like the Rectangle Drawing Tool in the Flash Authoring environment. The requirement is something like a rubberband tool where the user can define a portion of a map by drawing a rectangle over it. The coordinates needs to be captured.

View 1 RepliesI am working on a project right now that requires user input of dimensions to draw a bike. I am using actionscript to draw the bike on top of some bitmap images. the problem I am running into, is that the actionscript will not draw on top of the images. The images are on a layer below the layer with the actionscript.
View 2 RepliesI am using a custom Flex skin to create an active blur/frosted glass effect on the background of floating Panels, TitleWindows, and other containers (similar to http:url....). There is a background image in the Application skin, and potentially any number of other components above and below the active blur component. Here's some relevant code within the skin:
public static const BLUR_FILTER :BlurFilter = new BlurFilter(16, 16, BitmapFilterQuality.HIGH);
private var _bitmapFill :BitmapFill = new BitmapFill;
private var _matrix :Matrix = new Matrix;[code]....
Unfortunately, the performance of this when the component is being resized, and especially when moved, is poor. There is noticeable drag delay and overall slowdown, and this is with only one popped-up TitleWindow in the test application. There is especially poor performance when components inside the TitleWindow are changed (button hover states, etc.)I've attempted to optimized a little bit by avoiding reinstantiation of the blur filter, bitmap fill, and matrix, but this has had little or no effect. I removed the blur at one point, just drawing the Application to a bitmap, and the performance is still poor, so it's clear that it's mostly the BitmapData.draw() call.
I've read about using scrollRect and cacheAsBitmap, but I'm not sure where to apply these properties (or other optimizations I'm not aware of) within the Application or its components.

I made a movieclip with 5 frames inside. Well, outside, when i push a button stop, runs the code: this.movieclip_name.stop(); , but, doesn't stop.Inside these frames there is a enterframe function that call drawing api functions.
View 1 Repliesi need to draw an API Drawing and do the following with it;
-Effective experimentation with the drawing API e.g. gradient fills, curves etc.
-Effective rationalising of code using functions and loops.
-A sophisticated/realistic looking drawing, that shows the ability to use the drawing API with a high degree of skill.
how to create a sine wave using flash as3?and how to add changes to the wave based on changing frequency and wavelength using a slider.
View 2 RepliesThere are a couple of problems i'm having with this - the first is how to work out how to find where the tip of each sine curve is (ie the frequency) and the second is to work out how to rotate each object so that it slides sideways along the sine wave(note file is 800 x 600)here's my code: CarouselTest.as:

I am trying to work with this flash tutorial -[URL] So far it draws with a simple rounded line. I have been extending this application by making the drawing board bigger and other small things. I now want to be able to choose the line style. Currently it is rounded and I want to choose and draw with other shapes - square, forward slash (/), backward slash (). Is this possible? If so, could you explain how I could go about it?
View 1 RepliesI have a specific request or a general pondering really.I know you can create a sine wave type thing with as, could you then perhaps create movie clips, letter by letter that would move along and up and down on this sine wave?could you then, instead of setting the size and scale of the sine wave have it react to the input levels of a mic.i've been hunting for something that will help for a while and have drawn a blank
View 5 RepliesIm adding lot of simple functions to prototypes of top level objects ( Object , Array , String ...) and have 2 questions :
Is possible to add functions to top level's classes in compile-time ?
If not , is there a way to allow this functions to compile ? I dont like to turn off strict mode
ex:
string.removeWhiteSpace();
string.sliceStr("." , "end");
textField.scrollBottom();
this return compile-time error , cause there is no such function , i have to write it in braces :
string["removeWhiteSpace"]();
string["sliceStr"]("." , "end");
textField["scrollBottom"]();
and i like to aviod it )
I want to make a movieclip move on random sine wave. (sine path)I m trying to do this for a week and cant get it good.I want to make the curves random. and acceleration too.(it will be a fish like character swimming)Like as in this game : http:[url]..........(the small character which swim and move smoothly)this is the portion of code im using now.

I have a logo that I made in Fireworks, and it looks decent, but I was wondering if anyone could mimic it with movement. For example, if someone could use actionscript to make it "wiggle" or wave like a flag in the wind, that would be awesome.
Notice how the blue line itself stays at about the same thickness (it barely starts getting thicker), but the shading around it thickens as it goes more and more to the right.
Here's the image (ignore the text):
I'm generating a sine wave and playing it as a sound. But When I call SoundMixer.StopAll() it's causing a click when sounds stops. I think its because it's cutting the sound off in the middle of the wave, I was wondering of a way to make the sine wave slowly ripple out before i stop it. Is there already functions to do this in Action Script 3 or is my sine wave function i need to modify here is my code for the wave.
function sineWave(event:SampleDataEvent):void { var sample:Number for (var i:int=0; i<8192; i++) { sample = Math.sin((i+event.position) * ((2 * Math.PI)/44100) * freq); // freq is just any frequency event.data.writeFloat(sample * .15); event.data.writeFloat(sample * .15); } }
I am trying to create a similar effect to what is used in CityVille for dropping coins and experience icons, they do a custom move animation and it first moves a little bit up and then down. It looks like it is following a spline or a sine function.
