I'm currently working on a little practice .fla file I've been working on. What I have now is an altered version a 'game' I made recently. I wanted to see if it was possible to create a new instance and color by having the user drag the object into the black (target) area. In short I want the user to drag one of my shapes (movieclips) and while keeping the original shape in place, move the copy version into the target and have the copy change to a different random color.

I am trying to create a circle instance of FirstCircle class (by Milan Toth):
ActionScript Code:
package
{
import flash.display.Sprite;
[Code].....
I supposed the constructor would do all the work then. When testing the movie I get no error but no circle was displayed, trace statement put in the class constructor displayed the message ok. When I put the class code directly to the ACTION FRAME, it works fine.
what should I do to get the circle visible in the fla using the FirstCircle class?
I want to create new instance of item renderer for my data grid.
A single instance of your Item Renderer class (ListIR) is created for each visible item of the list-based control.
As the user scrolls through the items of a data grid control, Item Renderer instances are recycled rather than creating new instances.
But i would like to create new instance ..while scrollling item in datagrid.
ActionScript Code:
package {
import flash.display.MovieClip;
public class Base extends MovieClip {
public var baseHP:int = 50;
var newRect:Shape = new Shape();
1046: Type was not found or was not a compile-time constant: Shape. 1180: Call to a possibly undefined method Shape. What does it mean by "undefined method"? I am somewhat of a newby, so sorry if there are any stupid errors
Whenever I add shape hints to a shape tween the shape disappears in the between frames. I am using CS5 on Vista. I using files from [URL]to practice.

View 23 RepliesDoes creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 Repliesusing the shape tool you can draw basic shapesthen using the subselection tool you can re-shape them by relocating certain points
What i want to do is create a tween whereby one of the points is movedthe problem is you have to convert to a symbol first and after you have done that you cant change the shapes shape.so how do i go about using a motion tween to change the shape of a shape?
I have a datagrid with some custom renderrers and I'm just curious how I should approach the ability to freeze and always show the left 3 most columns at all times when scrolling left/right.
I thought that I might have to resort to 2 datagrids, side-by-side, the first showing the 3 columns that I want at all times, and the ability to scroll the rest. Only issue then I guess is linking the row selection to select that row in both and to tie the column sorts together...
Or would it be better to try and take columns 4+ and shrink their width to 0 as a person scrolls right, and then increase it back to the max width as they scroll left? Though that would cause funny issues to happen as the content of the datagrid would get smaller and smaller until you were 100% to the right and the scrollbar would disappear.
I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

From this (normal dataGrid)
into this (horisontal data grid)
How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)
Keeping all stuff DataGrid has like eating data from data provider sortind dragging - droping items etc
I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.
[Code]..
For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

I have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.
I have a BUNCH of bumpers of four types bounceUp, bounceDown, bounceLeft, bounceRight. during a collision which you hit determines the bounce so they always do the same thing so here's my question.....can i just name every bounceUp instance the same thing and then just add that one instance name to the list the collision detector checks?
i just dont wanna go through and name a hundred each of bounceUp s and bounceDown s individually as the potential for screaming increases proportionally.......
I placed a movie clip instance inside a button, and I want this movie clip to play when the button is released. I'm using this code on the frame containing the button:

Does anyone know if it is possinle to scroll a graphic or a movie instance as well as a text instance in flash. I want to scroll text and images as well. Actually text with imges embedded in it.
View 3 RepliesI am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

I have a general / somewhat newbie question. Is it better practice to call a function from another class like so:

Does one way free up more memory or enhance performance?
I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:
<mx:Style>
.headerCustomStyle
{
fontWeight: "bold";

I have a base class I've used on 6 different MC's. Then when I use these MC's my function runs an if statement to check which one to add.
if(id=design) var obj = new design();
if(id=team) var obj = new team();
I want to make it a bit more dynamic and use the id:String to evaluate which new instance to create.
ActionScript Code:
public function loadChapter(id:String):void {
var obj = new instance_of( id )();
}
I have a bunch of text boxes which are acting as labels on a diagram.The idea is all the labels are jumbled up to start with, and the user has to drag the labels to the correct place.So far, I have the labels, and they are dragable, but I want to be able to lock the label onto a specific area (I've called them crashzones) so that when the user drags the label onto the correct area, the label snaps into place.The 'crashzones' instance names, are indentical to the label instance names, with the exception that the 'crashzones' instance names have the letter 'z' at the begining.
On the dragStart event, something (maybe a string) would hold the instance name of the current label and add the letter 'z' to the beggining, so something like ... crashzone = "z" + label1;As there is an instance with the name "zlabel1", when the dragstop event starts, it'll do a 'hittestobject' on the instance "zlabel1".
I'm not entirely sure how to go about this.I've tried creating a string to hold the 'crashzone' name, but the hittestobject event doesnt work with strings i.e: hitTestObject(stringname);I've also tried with Sprite, but as the sprite technically already exists and has a name, I can't give the sprite any properties.
I have a base class which is being created via remote_object [RemoteClass alias] from the server.I have other specialized classes that are derived from this baseclass, but serialization with the server always happens with the base class.The base class has meta data that defines what the derived class is, for example
[RemoteClass (alias="com.myco...')]

I'm using a library that has a function that returns an instance of some class Engine.
I'd like to tack on some interfaces to Engine, so I subclass it class InterfacedEngine extends Engine implements AwesomeInterface. but when I change the code that uses the classes from this:
var engine:Engine = generateEngine();
to this: var interfacedEngine:InterfacedEngine = generateEngine();
It gives me a runtime error (elision mine):
TypeError: Error #1034: Type Coercion failed: cannot convert ...::Engine@1bc2bf11 to ....InterfacedEngine.
What about AS3 classes am I misunderstanding?
