I want to ask,
1 How to give focus to a TextField in AS3. in AS2 usually I'm using
Selection.setFocus("<name of textfield instance>");
fscommand("activateTextField");
2.How to duplicate movieclips in AS3. in AS2 I'm using
<name of movie clip>.duplicateMovieClip();
Thanks
These are two separate questions, both of which are answered online:
Use stage.focus to set the focus on any display object:
stage.focus = name_of_textfield;
There's no direct equivalent to duplicateMovieClip, but you can do approximately the same thing by creating a new instance from the original display object class and copying over properties from the original:
function duplicateDisplayObject(target:DisplayObject):DisplayObject {
var targetClass:Class = Object(target).constructor;
var duplicate:DisplayObject = new targetClass() as DisplayObject;
// duplicate properties
duplicate.transform = target.transform;
duplicate.filters = target.filters;
duplicate.cacheAsBitmap = target.cacheAsBitmap;
duplicate.opaqueBackground = target.opaqueBackground;
if (target.scale9Grid)
duplicate.scale9Grid = target.scale9Grid;
if (target.parent)
target.parent.addChild(duplicate);
if (target.hasOwnProperty("graphics") && target["graphics"] is Graphics)
Graphics(duplicate["graphics"]).copyFrom(Graphics(target["graphics"]));
return duplicate;
}
duplicateDisplayObject(name_of_movieclip);

I have a problem that after a lot of searches I didn't manage to solve it.
I created 2 movie clips in the library (let say mc1 and mc2). Then I manually create another movie clip in timeline (using IDE), let say foo.
As background inside foo I use mc1 with instance name bg. In ActionScript I'm trying to replace the foo.bg with mc2.
Please note that I already exported mc1 and mc2 to first frame with classes mc1() and mc2().
I tried (without any luck) :
var mc1:movieClip = new mc1()
var mc2:movieClip = new mc2()
if (....)
{
foo.bg=mc2;
}
Thanks
Mistake №1: managing objects in display list is not the same thing as assigning variables.
Mistake №2: variable names and class name MUST be different. On a case-level, at least.
So, you need to do something like that:
var mc1:MovieClip = new MC1;
var mc2:MovieClip = new MC2;
// ...
// Delete existing background.
foo.removeChild(foo.bg);
// Set the new background.
foo.addChild(mc2);
foo.bg = mc2;
I'm fairly new at ActionScript 3 but I am working on it and trying to learn by reading and modifying ActionScript source codes.
So far so good, however I stumbled upon one problem which I seemingly can't solve by myself. It should be faily simple for you guys tho.
The situation:
I got one "object" which is clickable and gives a random value which is also being saved in a variable.
I got another "object" which does the same thing but only has a different name.
I want the variable from the first object to be passed to the second one, how can I do it?
One way to pass values relies on using references to objects...
// mc1 and mc2 exist as movieclips on the stage
mc1.addEventListener( MouseEvent.CLICK, onClick );
mc2.addEventListener( MouseEvent.CLICK, onClick );
function onClick( event:MouseEvent ):void
{
// reference clicked movieclip through click target
var mc:MovieClip = event.target as MovieClip;
// if our clip matches one, assign the other clip the value.
if ( mc === mc1 )
{
mc2.value = mc.value;
}
else if ( mc === mc2 )
{
mc1.value = mc.value;
}
}
There's a thousand ways to pass references around, and this is just one.
OK guys let me show you the important parts of the code (cant show it all since I paid for it and I don't know whether the author woudl be OK with me publishing all of it).
I got these two objects there. When I click on one of the objects (which is a DICE), it gives me this code basically
var faceValue:int = 6;
// Add mouse click functionality to roll the die
addEventListener(MouseEvent.CLICK, onClickDie, false, 0, true);
mouseChildren = false;
buttonMode = true;
function onClickDie(e:MouseEvent):void {
removeEventListener(MouseEvent.CLICK, onClickDie);
buttonMode = false;
// Initiate the roll-out sequence
if(faceValue == 6) {
gotoAndPlay("rollout6");
etc...
Then somewhere in the frame where it is SPINNING the dice it is randomizing a number and save it into facevalue
// Calculate a random face value between 1 and 6
faceValue = 1 + Math.floor(Math.random()*6);
// Initiate the roll-in sequence
if(faceValue == 6) {
gotoAndPlay("rollin6");
...etc
Now how can I get the randomized facevalue from the spinning the dice frame to pass it to the other dice?
Currently I have an intro screen to my flash file which has two objects.
A button which will load an external flash file using:
var myLoader:Loader = new Loader();
var url:URLRequest = new URLRequest("flashgame.swf");
The second thing is a Numeric Stepper, which will be from 1 to 10. If the user selects a number e.g. 3 then the game speed I have set in the flashgame.swf should be changed
Such as:
var gameSpeed:uint = 10 * numericStepper.value;
But I think my problem is coming into place because the stepper and gamespeed are from different files.
Anyone got any idea please?
I have also tried creating a stepper in the game file and used this code:
var gameLevel:NumericStepper = new NumericStepper();
gameLevel.maximum = 10;
gameLevel.minimum = 1;
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
For some reason the stepper just flashes on the stage, no errors come up and the game doesn't work
When you execute you code, the stepper has no chance to wait for user input.
There is no time between theese two instructions.
addChild(gameLevel);
var gameSpeed:uint = 10 * gameLevel.value;
You should wait for user input in your NumericStepper, and then, on user event, set the game speed.
Edit: Yeah I know it's kinda sad to type out all this code (especially since some people wouldn't even be grateful enough to say thanks) but I think this question is important enough to justify the code as it may be helpful to others in future also.
Hi,
You were close. In your game file you could have put a var _setgameSpeed and then from Intro you could adjust it by flashgame._setgameSpeed = gameSpeed; It's a bit more complicated though since you also have to setup a reference to flashgame in the first place. Let me explain...
Ideally you want to put all your code in one place (an .as file would be best but...) if you would rather use timeline then you should create a new empty layer called "actions" and put all your code in the first frame of that.
Also change your button to a movieClip type and remove any code within it since everything will be controlled by the code in "actions" layer. In the example I have that movieclip on the stage with instance name of "btn_load_SWF"
Intro.swf (Parent SWF file)
var my_Game_Swf:MovieClip; //reference name when accessing "flashgame.swf"
var _SWF_is_loaded:Boolean = false; //initial value
var set_gameSpeed:int; //temp value holder for speed
var swf_loader:Loader = new Loader();
btn_load_SWF.buttonMode = true; //instance name of movieclip used as "load" button
btn_load_SWF.addEventListener(MouseEvent.CLICK, load_Game_SWF);
function load_Game_SWF (event:MouseEvent) : void
{
//set_gameSpeed = 10 * numericStepper.value;
set_gameSpeed = 100; //manual set cos I dont have the above numericStepper
if ( _SWF_is_loaded == true)
{
stage.removeChild(swf_loader);
swf_loader.load ( new URLRequest ("flashgame.swf") );
}
else
{ swf_loader.load ( new URLRequest ("flashgame.swf") ); }
swf_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, Game_SWF_ready);
}
function Game_SWF_ready (evt:Event) : void
{
swf_loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, Game_SWF_ready);
//Treat the Loader contents (flashgame.swf) as a MovieClip named "my_Game_Swf"
my_Game_Swf = swf_loader.content as MovieClip;
my_Game_Swf.gameSpeed = set_gameSpeed; //update gameSpeed variable in flashgame.swf
//also adjust SWF placement (.x and .y positions etc) here if necessary
stage.addChild(my_Game_Swf);
_SWF_is_loaded = true;
}
Now in you flashgame file make sure the there's also an actions layers and put in code like this below then compile it first before debugging the Intro/Parent file. When your Intro loads the flashgame.swf it should load an swf that already has the code below compiled.
flashgame.swf
var gameSpeed:int;
gameSpeed = 0; //initial value & will be changed by parent
addEventListener(Event.ADDED_TO_STAGE, onAdded_toStage);
function onAdded_toStage (e:Event):void
{
trace("trace gameSpeed is.." + String(gameSpeed)); //confirm speed in Debugger
//*** Example usage ***
var my_shape:Shape = new Shape();
my_shape.graphics.lineStyle(5, 0xFF0000, 5);
my_shape.graphics.moveTo(10, 50);
my_shape.graphics.lineTo(gameSpeed * 10, 50); //this line length is affected by gameSpeed as set in parent SWF
addChild(my_shape);
}
The key line in intro.swf is this: my_Game_Swf.gameSpeed = set_gameSpeed; as it updates a variable in flashgame.swf (referred as my_Game_Swf) with an amount that is taken from a variable in the Parent SWF.
This is just one way you can access information between two separate SWF files. Hope it helps out.
I am trying to migrate as2 to as3 code. The normal solution to my problem involves using the first parameter of the createEmptyMovieClip() as the name of your movie clip. In several instances I have a dynamic value for this first parameter- so my question is How should I go about doing this?
//my code
function someFunction (){
loader_mc = this.createEmptyMovieClip("text"+value, value);
value++;
//do stuff with it
}
//normal non-dynamic solution
function someFunction (){
var text:MovieClip = new MovieClip();
addChild(text);
//do stuff with it
}
In your question, you're already saving a direct reference to the MovieClip. If that's the only reference you need to do your work, then you really don't need to give the MovieClip a name.
If you do need the name, though, you can always assign the MovieClip a name after the fact:
var myClip:MovieClip = new MovieClip();
myClip.name = "text"+value;
parent.addChild(myClip);
This will let you use the getChildByName method:
parent.getChildByName("text"+value);
I am trying to create a function which adds a text box (a blue rectangle) and a textfield on the box. I have a class in the library named textBox, no external classes used.
I started actionscript 3 (before even learning many of the programming fundamentals) about a month ago, so I am not experienced with this.
function createTextBox() {
var textBoxCoordX:int = 305;
var textBoxCoordY:int = 80;
var dialogueBox:textBox = new textBox;
var dialogueText:TextField = new TextField();
addChild(dialogueBox);
dialogueBox.x = textBoxCoordX;
dialogueBox.y = textBoxCoordY;
dialogueText.x = textBoxCoordX+5;
dialogueText.y = textBoxCoordY+5;
dialogueText.text = "Insert Text Here";
}
After playing, I immediately get two errors that link me to "var dialogueBox:textBox = new textBox;" These errors' descriptions say "1046: Type was not found or was not a compile-time constant: textBox." and "1180: Call to a possibly undefined method textBox."
Ensure that the linkage is set. Right click, advanced, tick Export for ActionScript.
i think no find textBox movieclip,
You must determine the library has the movieClips and the linkedname called textBox.
