Is it possible to conditionally change the direction of a for loop in ActionScript?
Example:
for(if(condition){var x = 0; x<number; x++}else{var x=number; x>0; x--}){
//do something
}
Introduction: I have a flat ArrayCollection of object's, which i group to create the dataProvider for an AdvancedDataGrid. In this AdvancedDataGrid i have different branches representing different type of tasks. I want to conditionally change the icon for the leaf nodes in the AdvancedDataGrid based on a date field stored in each object.For this purpose lets say each Task object contains an id and an updatedDate (Representing when the task was last updated). If the task has not been updated in the last five days (updatedDate+5 < today) the icon of that leaf node(Task) should be red, in constrast to the opposite the leaf icon in the AdvancedDatagrid should be green, e.g. like the image below. In this case task 35 has not been updated in the last 5 days, while 13 and 39 have.
Question: How do i change the leaf icons in the ADG based on the updatedDate of the underlying object? I would think that i have to extend AdvancedDataGrid and override some method, but which and how?I have seen easy ways of changing the open and closed icons on the web, but no way of conditionally changing an open node's icon :)
I have to designed a datagrid, in first column i have to use closed lock icon. when i click a row in a datagrid the selected rows' icon should change as opened lock icon. how i can achive this task in flex 3.
View 2 RepliesWith mx:Box I can set the direction to be either "horizontal" or "vertical". I'd like to reverse the order of the components in the box though. For example:
Before:
|button1| |button2| |button3|
After:
|button3| |button2| |button1|
I've created a custom component that lives in a mx:Box and would like to do this in as simplest a way as possible.
I create a TLFTextField object at design time and need to change its direction at runtime, how this could be possible? the following code did not work and simply ignored: var myText:TLFTextField = MyText;myText.textFlow.direction = "rtl";

View 1 Replieshow I change the direction of a movie clip. And how to make it change in the same it's moving.
I have random movement code on the clip, I just want it to rotate, in the direction it goes.
function moveStuff(){
if(Key.isDown(Key.DOWN)){
this._y += 5;
}
if(Key.isDown(Key.UP)){
[code]...
thats my basic Arrow key functions to move a movie clip lp_mc is my character in the left position so when left key is pressed it moves forwards but when right is presssed it moves backwards... i have a movieclip called rp_mc which is the same thing but facing the other way when right is pressed how do i swap the lp_mc for rp_mc so it changes direction?
How could I get an object to follow the cursor and rotate to change direction as the cursor changes direction?
View 5 Repliesi'm trying to animate a movie clip by subtracting from its y value and then when it reaches a negative value change direction and animate by adding to its y value until it's back to 0 and loop back and forth. what i have isn't working.

var direction:Boolean;
if(body.y > 0){

when it reaches -500 is jumps back and forth.

how to get it to go from left to right, rather than right to left as it does now. Been messing with it for a while and have no idea what to do.
what i have is a circle image (for this purpose lets say it looks like a clock). For example: when you click 3 o'clock, the whole clock needs to rotate around with the 3 o'clock btn at the 6 o'clock position (with the pivot point in the centre). each of the 'time' positions (2 o'clock, 3 o'clock, 4 o'clock ...etc) needs to be a button and thus be able to rotate around to the 6 o'clock position.This would seem simple enough by just using a.rotate value or using tween movieclips...however the tricky part is:the actionscript needs to determine which way the clock turns (anti/clockwise), dependant on where the clicked time-btn's position is. it needs to be some sort of if statement that says:if (3'oclock-btn) is positioned between 0 degrees (being original 12'oclock position) and 180 degrees (original 6 o'clock position), then rotate clockwise to the 6 o'clock position. If the (3o'clock btn) is positioned between 180degrees and 259 degrees (12 o'clock position), rotate anti-clockwise to the 6'oclock position.
View 5 RepliesI'm building a simple 360 degree image rotation effect using single frames and forward and back buttons. I'm new to AS3 and have managed to create functioning buttons... (so my code may be a bit odd!)But now I also want to advance frames by clicking and dragging on the image itself (or on an invisible button sat on top of the image).Although there are some threads here which have asked the same thing, I don't understand how they were answered. My code is below, and the file I am practising with is on:URL...At the moment if you click on the image area it will advance but as there is no code detecting mouse direction, it just goes forward. Can anyone help me understand how to implement a simple direction detection and then use this to decided whether to advance or go backwards.[code]
View 16 RepliesI want to make a movieclip moves smoothly and when it changes the direction, it can turn smoothly but not a sudden turn, I try out the code below. and the truning is odd:
this.rotation = (Math.atan2(targetY-this.y, targetX-this.x )/Math.PI)*180;
I want to change the TLF text fields direction dynamically.
View 4 RepliesI'm having a problem changing the direction of a movieclip using hitTestPoint. I have some balls on the screen that only move left, right, up and down. and pending the way they are moving they have to change direction. if they're moving right they have to change to up. left to down, up to right and down to left. I tried the following code for getting a ball moving moving right to change to up. note: movingDir is just a string i use to keep track of how the ball is moving and is defined initially in another class. here is a snippet from the ball class:

I'm trying to set up a script which would force an object to move through the stage until a particular point and than change direction. I wrote something like that:
onClipEvent (enterFrame) {
moveUp = function () {
this._y -= 1;
if (this._y<-30) {
this.onEnterFrame = moveDown;
}};
moveDown = function () {
this._y += 1;
if (this._y>600) {
this.onEnterFrame = moveUp;
}};
this.onEnterFrame = moveUp;
}
But it doesn't work. the object moves only one direction and does not change it.
I've got a movieclip which follows a predefined path (like in those tower defense games). Normally the mc changes the direction it faces with Math.atan2 method and then rotates the movieclip, but because this game is in a tilted view( in stead of directly from the top) I need it to change the frame in the MC according to the direction it's facing.
Is it possible to read out Math.atan2 method data, and then change the frame the MC is displaying, according to this data? I used [URl]...on-and-realism as a base for this game. If Math.atan2 method

View 1 RepliesI'm making a Myst clone and want the cursor to do different things when it mouses over various objects and regions, for instance:
- Turns into an open hand when over a grabbable item.
- Turns into a right-facing arrow when on the right side of the screen signifying "turn right here".
- Turns into an icon of an inventory object when the object is selected.
How is this done? I found some code that sort of did it, but it was sloppy, the cursor flickered like crazy, and overall it sucked. I want to harness in Flash the same mechanism that makes my cursor turn into the bracket thing when it's over a text field, or a finger when over a link.ALSO I want to be able to make the arrow stay a regular arrow when it's over manipulatable items I want to remain secret.

View 8 Replieshave a ball with the name of mc which can be moved using the keyboard .. when you press the left mouse button shoots the ball, this ball and the other flies in the face where the cursor was in the shot .. but if you move the cursor to another location and shoot a second time then the second ball is also flying in the direction of the cursor and the first ball change direction toward a second shot ..
ActionScript Code:
import flash.display.MovieClip;
import flash.display.DisplayObject;
import flash.events.MouseEvent;

how to make that first ball did not change its direction and continued to fly in the direction of the shot?
At work we have a lot of AS3 code that conditionally performs logging or assertions like so:
[Code]...
Is there any way to do something similar in AS3, or do we have to do the conditional compilation blocks around everything? I have been looking around manuals but have found nothing useful yet.
by the way you need to make a symbol and need to export for ActionScript and class name is "ball". And the button instant name is:bButton. So here's the script I wrote so far.
var boundaryRight:Number = stage.stageWidth;
var boundaryLeft:Number = 0;
var balls:Array;[code]....
As you can see that code made the multiple ball go to left and looping over and over again. So here's what I want to do. I want to make a button and when I click the button it'll change direction like click and it change direction to right. I click it again and it'll go left again. How do I write the code for that?
