ActionScript 3.0 :: Bezier Curve That Is Generated Dynamically?
Dec 30, 2009
i have a bezier curve that is generated dynamically now i want to mask an image with it to produce a cut of face functionality just like in elfyourself.com or in jibjab.
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.
I have series of Bezier curves that I want to revolve about an axis to form a solid model in Papervision3D.How would I do this? Has someone created a class for Papervision that can revolve a curve to form a solid?
I need to implement a drag and drop functionality, where I can define and constraint the route of the draggable object.[URL].. only that i have the paths designed and not calculated by a math function. So, in fact, as mouse moves I need to tell the object to follow the custom path/movieclip.
Does 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]..
I have to dynamically animate some bezier curves that have to look like this. Here is the archive of my approach and I'm not sure is the best one. I mean it kind of eats the whole processor.
I have a world map on which I display some data. I read long and lat coordinates for two countries from an XML file which is updated with different coordinates everytime. I then map the coordinates to X-Y axis using some projection method.
So, I have x-y coordinates for two countries. I wanna draw a curved line between those countries but curveTo method draws the curve in one shot. I want to animate the curve drawing part so it looks like it is being drawn real time.
I want to curve a dynamic text from a straight line to circular curve (using a slider). I have placed the characters of the string in each textfield created at runtime.
I was hoping someone could help me working out some advanced data reformatting. What I'm hoping for is a function where I can input a value along with an array of key positions like so:
function remap(percentage:Number, keypoints:Array) { ...
The array would start with the minimum and end with the maximum point, with nested key points along the way. For example, I would input something like remap(0.25, [0:0,80:50,100:100] ) and the function would 'imagine' a spline curve graph from (0,0)-(100,100) with a key point of (80,50), then return the y value that is 25% along that graph.
I have a curveTo an anchor point and a control point.Then I have a function that will return the x and y of a point along that curve if I give it a number as a percentage of the curve (0 to 1).It looks like this, and works perfectly..
x0,y0 are the start point, x1,y1 the control point and x2,y2 the final anchor point.But... I want to give it a _y value instead of a percentage (interval) and it return where on the curve that would intersect.
I wish to have a 3d carousel much like a flash one in the below link : [URL] however, i wish the images to be dynamically generated and at the same time txt 'beneath' (to be added) the picture to be dynamically updated also...through a database. I wish to get it connected to a back end and probably use a content management system.
ok, here's the deal. We are creating an ecard that will be customized by the sender, and sent to soldiers in Iraq. There are about 5 different things that the sender can customize, as well as write a message. The goal is to have their choices sent to a database and then inserting those variables when the receiver watches the movie.Now, instead of creating possibly thousands of XML files (one for each sender), we decided it would be better to just generate the XML on the fly from the info in the db. But my question is, how do I handle loading that XML? Since this won't just be a static page on the server, I'm not sure how to go about it. I'm wondering if you can use variables when loading XML, for example:
Code:my_xml.load("senderData.xml?user=LyndaSmith");Basically, how can i create an XML file on the fly with the values from the DB, that can then be loaded into Flash?I have virtually no experience with db's, so this is the method I came up with because I do have some experience with XML. I have a developer who will actually insert the values into the database with ColdFusion, and he can also generate the XML, I just need to be able to load the dynamic XML in flash when the receiver watches the card.
I've been trying to write AS3 that can read xml which is dynamically generated by php.i've generated the xml in several ways all of which seem to work but i keep getting the error,Error #1088: The markup in the document following the root element must be well-formed,when i try to load the xml into flash. however the xml (as viewed when you go to "view source" in your browser) is indeed well formed.i have 4 versions of the php.the first just uses echo. the second uses echo but i wrap it in {start_ob(),ob_end_flush()}; then i use simpleXML and finally i use domdocument.[code]
I have a movieclip that I am adding to the stage dynamically. The movieclip has to be placed at specific coordinates to match the current text field.The coordinates that show on the INFO tab are x=264 and y= 365. However, in order to get the movieClip to match those I have to set x to 398 and y to 200.If I set the coordinates to those in the INFO tab then the movieclip does not show; it appears off stage.
My company has a database-driven system of web forms, each ofwhich consists of many questions in various layouts (2-columnradio, 1 column checkbox, etc). The forms are never hard-coded.Each HTTP request causes Java code to perform DB queries todynamically generate the various questions and answers.Thosequestions are then rendered through JSP and Struts tiles into HTML.The HTML also contains JavaScript functions to hide/showconditional questions on the web page based on answers to earlierquestions. Now we're trying to figure out the best way to adapt thissystem to use a Flash front-end instead of HTML/JavaScript.My preliminary research suggests at least two possibleapproaches:
1. A pre-compiled SWF could send a request with certainparameters, and the server could respond with an XML description ofthe form to build. Then the SWF could parse that XML andynamically generate the form using attachMovie for each formelement (with a lot of math to determine relative positions ofelements with variable sizes, like text labels). 2. Flex might reduce the code for placing elements, by usingMXML to describe the form structure as well as visual arrangement.I haven't used this yet, and I'm wary of Flex 2 simply because itrequires Flash Player 9 which is only at 50% browser penetration
I'm currently reading in data from an XML file. Each attribute of a child is assigned as a property of a movieclip as shown in the code attached. However, what i'd like to do is not have the property names already decided as i don't necessarily know how many attributes a child in the xml file will have. Is it possible to dynamically name the properties depending on what number attribute they are...?
I've tried to generate movieclips dynamically the method I have used does the following: Uses a loop runs depending on how many movieclips I want to generate e Each time the loop cycles it creating a new movieclip instance Adds the new movieclip to an array Uses method addChild to put moveclip on the stage then draws a rectangle begins fill ends fill Adds it to that movieclip
I then use a conditional statement checking if the movieclip is the first item in the array if so it sets the current MovieClips x and y position to a chosen value. the first movieclip is used for a starting point to align the rest of the generated movieclips to. If not the movieclips x and y position are set to the previous array items x and y position + current movieclips width or height + the gap I would like them to have. Then the cycle repeats. I've coded this using timeline code and it works fine the shapes appear on the stage no errors. I tried to move this code off the timeline to an as file and the code has no errors but when run I just don't see the objects even if I trace there x and y positions I don't see them on the stage.
Timeline Code var mcArray:Array = new Array();// DEFINE ARRAY FIRST var randomNo:Number; var colorStr:String; var currentColor; var movieClip:MovieClip;// TEMPORARY VARIABLE [Code] .....
I have a Flex application which references a separate MXML file as a template for a custom component. I create instances of the component dynamically several times in my program, but I need to get a handle that will allow me to modify that instance of the component as desired. I pass specific information to this component on instantiation using bindable public variables in the component's MXML file. I add it to my main program using addChild().
I want to update the component's progressbar as necessary and I want to remove it from the box to which I addChild'd it. What's the easiest/best way to get a variable that will give me predictable access to each component so I can easily manipulate the components as necessary? Some research suggests creationComplete, but I decided it was faster to just ask than to go through lots of different experiments and come up blank.
I'm not quite sure how to describe the problem I'm having but I'll do my best. I have an image gallery built in AS3 that loads content via an XML file. Nothing mind blowing here... When testing locally on a static XML file, the gallery works as intended. The purpose of this gallery is to function within a CMS and load dynamically generated XML files to display the appropriate images/info for each particular gallery. All this functions fine, to an extent...
The first part works, I can "firstText" and I can make it go to frame 9 and stop but I can't manipulate the movie clip "title_txt" which is inside "firstText"
So basically my file is a photo gallery. There are two ways to click through the photos - the previous/next buttons or the camera icons on the floor plan diagram. The cameras are dynamically generated from XML, into a cameraHolder mc.
I have the controls working independently, but I need to have them working together (ie: if you click the previous/next buttons, the camera icons would change state) I don't have all the over/selected/visited states working yet, but I don't really need help with that.
What I really need to be able to do is figure out how to call the camera icon clips. See line 138 for where I tried to trace one: trace(cameraHolder.camera0); It returns as undefined.?
Also is is possible to call a mc where part of the name is a variable? For example, you'd call something like "camera" + whoIsOn instead of camera0?
FYI: this file is definitely a work in progress. I kind of slapped together two examples to get what I currently have...
I'm trying to make a flash widget that loads thumbnails from an xml document and have each thumbnail link to a different web page. So far everything works fine but I don't like using _root incase the widget gets loaded into another swf. In my expereice _lockroot dosen't always work.the line highlieted in red will only work if targeted through root as opposed to all my othere reference to ["placeHolder"+i] which use this.["placeHolder"+i]. I've tried _parent, this._parent and adding lots of other _parents. Nothing will work this is the file structure _root.placeHolder'N'.tn_mc. how I can substitute _root for a relative path.
widget_xml = new XML(); widget_xml.ignoreWhite = true; widget_xml.load('flashWidget.xml');//path to document
I am loading several images from XML to dynamically generated movieclips (mc_1, mc_2, mc_3...etc.). Then adding all of them into a parent MovieClip - imageContainerMc. So now, imageContainerMc holds mc_1, mc_2... etc. What I want to do next, is to Duplicate the imageContainerMc, and add both the instances on Stage-- addChild(imageContainerMc), addChild(imageContainerMc_duplicate).how can I duplicate a dynamically generated MovieClip?
I've got an object in the library that's a basic rectangle with an outline. A for loop creates a grid dynamically. I want to create a mask that goes over this grid. I'm using "my_object.mask = my_mask", but to no avail
