Flex :: Spline For Non Differentiable Function?

Jun 16, 2009

I have a function that sometimes is non-differentiable at a point. When I now use a spline (Bezierspline in degrafa) for interpolation the interpolation at this point does not work as expected (at this point my function has a kink). Now when interpolating with a spline it draws some kind of loop around this point. I think this happens because the spline needs the derivatives of the functions which is not unique at this point.

Flash :: Function For Extrapolating Points On A Spline Curve Or Hermite Curve Similar To Keframe Interpolation?

Aug 26, 2011

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.

Flash :: Draw A B-Spline Using Bezier Curves?

ActionScript 3.0 :: Math - Smooth Spline From Points?

Jun 18, 2011

Attached is a mockup of what I'm after. Notes:

1. Spline appears smooth

2. Spline does not necessarily go through the points

3. The start and end point of the spline is not important

I'm sure there are ways to calculate this, but without knowing the proper terminology searching isn't turning much up,

ActionScript 2.0 :: Drawing Curves Like Spline Chart?

Nov 25, 2010

I have five dots(MovieClips) in my stage. I want to draw a curve which should touch all the five dots. The x position of dots are incremented by 50 px and y position is random.I can do this using lineTo. But it has not got any curve effect.

Here is the code using lineTo

Code:
_root.createEmptyMovieClip("circle",1);
with (_root.circle) {
clear();

[code]...

I tried curveTo to achieve this. But it is not working.

Flex :: Require A Function Parameter To Be A Static Constant Of The Function's Class?

ActionScript :: Flex - An Object Returned From A Function Call Changed The Next Time The Same Function Is Called?

Jan 10, 2012

I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:

package
{
public class PER
{
[Code].....

Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:

var data_set1:PER = function_name(arg1, arg2, arg3);

The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:

var data_set2:PER = function_name(arg4, arg5, arg6);

My intention is that data_set1 and data_set2 are different (e.g. not linked together).

My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?

Flex :: Get Function Name From Function Object?

Aug 4, 2009

Given a Function object, can you get its name as a String? See example:

function doThingWithCallback(callback:Function):void {
trace("i'm going to run " + callback); // outputs "i'm going to run function Function() { }"
}

[code]....

This example is sort of arbitrary, but it would be very useful to get function names for debugging, particularly when passing around Function objects.

Actionscript 3 :: Flex - Selection In Flex Datagrid Does Not Pass The ValueObject To SelectionChangeHandler Function

Aug 11, 2011

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:

1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

Flex :: Sequence Flex/Actionscript Method/function Method Calls

Aug 11, 2011

OK, from what I know actionscript in Flex runs asynchronously. I need the ability to run a method in a loop synchronously. Consider this code:

This is not my exact situation as it is a bit more complicated to explain here. There is an abstract class and several custom view objects derived from it. Some of the views are dependent on others being completed first but I cannot seem to order them in the correct order. TIMERS are not an option. Probably not explaining this correctly.

Flex Set Function Not Getting Called

I've been banging my head against the wall with this one. I have the following set function in Flex. [code]If I set the periodChangeAmount to -1 or 1 the set method gets fired. If I set it to zero it doesn't get fired. What's the deal? Does anyone know why it wouldn't get called when setting it to zero. If I change the object type to a number or even an object it still doesn't work as expected.

Flex :: Define A Function In One Component From Another?

Feb 1, 2010

I'm a complete Flex/Flash noob, running Adobe Flash Builder 4 Beta 2. I have a main component that needs to be able to call several popups, each mostly the same except for one function and a few labels. Obviously, I'd prefer to be able to define this function and change those labels when calling the popup instead of having tons of .mxml files with nearly the same code, I just don't know how to do it. I figured out how I can change the labels, but not sure how to redefine the function.For simplicity's sake, let's say my code looks like this:

main.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009" :s="library://ns.adobe.com/flex/spark"

Flex :: Settingflex Datafield With A Function?

Feb 6, 2010

I can't seem to get this right and everything I read is kind of like my problem but not quite. This seems like it would be pretty easy. All I want to do is set the value of a datafield using a function. I call in an xml file and can set the value of a datafield from that xml (in this case it's a category id as a number). But then I want to translate that number into a name by correlating it with a different data array.

so basically i just need to pass the catId into a function in the datafield but can't get it to work.

<mx:DataGridColumn color="0x00101F" textAlign="center" editable="true" id="categoryField" headerText="CATEGORY" dataField="getCategoryName(@catId)" editorDataField="text"></mx:DataGridColumn>

Flex :: Run Function On Popup Close?

Mar 3, 2010

I've got a flex project that I'm working on. Currently I've got a popup that consists of another mxml file containing a form.

Once the form is filled in and submitted I'd like to run another function then the popup closes on the main mxml file, but I'm not sure how to go about doing this?

Here's my popup code

private var weightadd:weight_add; //POP UP ADD WEIGHT FORM
private function weightAdd():void {
weightadd = new weight_add();

[Code]....

Currently in my weight_add.mxml file I'm using a button to close the popup, I'd like have this button close the popup and then call a function in my main.mxml file - I'm just wondering how I go about doing this.

<mx:Button x="186" y="83" label="Cancel" styleName="formbutton" id="cancel_button" click="PopUpManager.removePopUp(this);"/>
