Though coding, I must make many copies of the same MovieClip to be placed on the stage, each to be manipulated code-wise on its own
For instance, I have a MovieClip named MC and I wish to have 99 copies of ít loaded onto the stage, each in a different x coordinate. What should I do?
I think on doing this:
Step 1: in the library, turning MC into a class
Step 2: placing the following code in the scene's script
var MyArray:Array = new Array
for (var i:int = 0; i<99;i++)
{
var MCInstance:MC = new MC
MC Instance = MyArray[i]
MovieClip.(MyArray[i]).x = i*30
}
Would that make sense?
That's probably the right idea, your syntax is just a little off. Try this:
var myArray:Array = [];
for (var i:int = 0; i < 99;i++)
{
var mc:MC = new MC();
myArray[i] = mc;
mc.x = i * 30
}
AS3 style conventions: use lowerCamelCase for variable names, don't omit constructor parens even though they are optional, and create arrays using literals (source).
You could push each MovieClip to an Array after adding it to the Stage.
var myArray = [];
for(var i:int = 0; i < 99; i++)
{
var myMc:MC = new MC();
addChild(myMc);
myMc.x = myMc.width * i + 2;
myMc.y = 10;
myArray.push(myMc);
}

So I want to code faster by making array of all button that I have, and also make array of function which index numbers are connected to the array of each buttons.
For example, buttons[0], handler events for hover is button_over_funcs[0] and for out is button_out_funcs[0].
To make it clearer (since english is not my first language), take a look at my code:
var buttons:Array = [playbtn, tutorialbtn];
var button_over_funcs:Array = new Array();
var button_out_funcs:Array = new Array();
var i = 0;
for each(var j in buttons){
j.buttonMode = true;
button_over_funcs.push(function(e:MouseEvent){
j.gotoAndPlay("hover");
});
button_out_funcs.push(function(e:MouseEvent){
j.gotoAndPlay("out");
});
j.addEventListener(MouseEvent.ROLL_OVER, button_over_funcs[i]);
j.addEventListener(MouseEvent.ROLL_OUT, button_out_funcs[i]);
i++;
}
but the j will always refer to tutorialbtn, regardless which button I hover/out. I tried for-in as well
var buttons:Array = [playbtn, tutorialbtn];
var button_over_funcs:Array = new Array();
var button_out_funcs:Array = new Array();
for(var j in buttons){
buttons[j].buttonMode = true;
button_over_funcs.push(function(e:MouseEvent){
buttons[j].gotoAndPlay("hover");
});
button_out_funcs.push(function(e:MouseEvent){
buttons[j].gotoAndPlay("out");
});
buttons[j].addEventListener(MouseEvent.ROLL_OVER, button_over_funcs[j]);
buttons[j].addEventListener(MouseEvent.ROLL_OUT, button_out_funcs[j]);
}
Both seems the same. It seems like actionscript always refers to the last value of j instead of assigning it. Do you have any idea on how to make this as I expected? Is it impossible to make this quicker and not assigning the button to do same exact stuff?
There's no point in reinventing the wheel. Use SimpleButton and be done with it.
In general: a class is the way to go when you want to define behaviour that several objects have in common.
So I found the way by myself. If you found same problem as me, you can take a look.
var buttons:Array = [playbtn, tutorialbtn];
var button_over_funcs:Array = new Array();
var button_out_funcs:Array = new Array();
function addOver(ob){
button_over_funcs.push(function(e:MouseEvent){
ob.gotoAndPlay("hover");
});
}
function addOut(ob){
button_out_funcs.push(function(e:MouseEvent){
ob.gotoAndPlay("out");
});
}
function addEvent(ob){
addOver(ob);
addOut(ob);
}
for each(var j in buttons){
addEvent(j)
}
for(var i = 0; i<= buttons.length - 1; i++){
buttons[i].buttonMode = true;
buttons[i].addEventListener(MouseEvent.ROLL_OVER, button_over_funcs[i]);
buttons[i].addEventListener(MouseEvent.ROLL_OUT, button_out_funcs[i]);
}
I am trying to create dynamically generated variables based on another variable, such as:
var limit = 2;
$scope.blank_item = [];
$scope.create_vars = function(limit){
for(i=0; i<limit; i++){
eval('var item' + i) = $scope.blank_item;
};
};
And this should give me 3 new variables like below:
var item0 = [];
var item1 = [];
var item2 = [];
However, when I try to do this, I get the following error message:
ReferenceError: Invalid left-hand side in assignment
Is there something fundamentally wrong with my logic?
This has nothing to do with Angular. The value passed to eval() has to be one or more statements, not part of a statement. And you certainly can't pass part of a statement to eval() and then assign a value to it.
Even you could do that, it would just be creating temporary variables that disappeared as soon as your function finished executing.
Ditch the eval() and use an array:
var limit = 2;
var items = [];
$scope.blank_item = [];
$scope.create_vars = function(limit){
for(i=0; i<limit; i++){
items[i] = [];
};
};
im new to using action script so i apologies if this wont make sense, the issue iam having is that the incoming bytes from my arduino are not being stored properly in an array. The bytes come in one at a time from my arduino and will be stored in an array in as3.
i have two values SF-F8-001, SF-F8-002 and SF-F8-003 etc... when i trace the incoming bytes i get this:
S
F
-
F
8
-
0
0
1
so when i look at that i realized i needed an array to store the byte as they come in however i have tried many different things but it hasnt worked
however this code below seems to get me close to my desired result
import flash.events.*;
import flash.net.Socket;
import flash.utils.ByteArray;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLVariables;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequestMethod;
var ary:Array = new Array();
var bar_grab:Array = new Array();
var array:Array = new Array();
trace("__AS3 Example__");
var socket:Socket = new Socket("localhost",5331);
socket.addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
function socketDataHandler(event:ProgressEvent):void
{
var str:String = String(socket.readUTFBytes(socket.bytesAvailable));
var b:String;
bar_grab.push(str);
b = bar_grab.join("");
boxtwo.text = b;
}
this code gets me this
SF-F8-001SF-F8-002SF-F8-003 etc...
however the result iam looking for is this
SF-F8-001,SF-F8-002,SF-F8-003 etc....
so if anyone could help me sort this out i will be grateful
thank you
If you know a priori how many characters each item will consist of you could read everything to string and get each individual item like that:
//Main string containing all items
var allString:String = "123456789";
//Number of chars in of item
var charsInItem = 3;
var item:String;
var index:int;
var resultArray:Array = new Array();
for(var i:int = 0; i < allString.length/charsInItem; i++)
{
index= i*charsInItem;
//traces name of one item
item = allString.slice(index, index+charsInItem);
resultArray.push(item);
trace(item);
}
//Output:
//123
//456
//789
If you don't know a number of chars in one item or it varies, I would suggest tweaking Arduino code and putting some sort of a marker in between every item. Like say a comma (,). Then your string would look something like this: "item1,item2,longerItem3". And you could split that string into array like that:
var array:Array = new Array();
var allString:String = "item1,item2,longerItem3";
//This splts string into array items using comma (,) as a seperator
array = allString.split(",");
for(var i:int = 0; i < array.length; i++)
{
//trace every array element
trace(array[i]);
}
//Output:
//item1
//item2
//longerItem3
I should add that even if you know a number of chars in one item I would still suggest using method nr.2.
trace (suallar); - is written 2 times
1st time - HERE IT SHOWS ALL THE ELEMENTS OF THE ARRAY suallar
2nd time - BUT HERE THIS ARRAY SEEMS TO BE EMPTY, EVEN THOUGH I DIDN'T MANIPULATE WITH IT OR MAKE IT EQUAL TO ANYTHING I MANIPULATE WITH IN BETWEEN
var suallar:Array = new Array();
var i:int;
var cavablar:Array=new Array();
suallar.push(["sual1", "duz1", "sehv11", "sevh12", "sevh13","sevh14"]);
suallar.push(["sual2", "duz2", "sehv21", "sevh22","sevh23","sevh24" ]);
suallar.push(["sual3", "duz3", "sehv31", "sevh32","sevh33","sevh34"]);
suallar.push(["sual4", "duz4", "sehv41", "sevh42","sevh43","sevh44"]);
suallar.push(["sual5", "duz5", "sehv51", "sevh52","sevh53","sevh54"]);
var cavablar_temp:Array = suallar.concat();
for (i=0; i<suallar.length; i++){
cavablar_temp[i].shift();
}
trace (suallar);
for (i=0; i<suallar.length;i++){
var number_array:Array = cavablar_temp[i];
var final_array:Array = [];
var count_selected:int = 5;
for (var u = 0; u < count_selected; u++)
{
if (number_array.length == 0)
{
break;
}
else
{
final_array.push(number_array.splice(Math.floor(Math.random() * number_array.length), 1)[0]);
}
}
cavablar.push(final_array);}
trace(cavablar.join("\n"));
trace (suallar);
As per the Array.splice() documentation:
Adds elements to and removes elements from an array. This method modifies the array without making a copy.
When you do number_array.splice() in the middle of your loop, you're modifying the original arrays you pushed to suallar.
Take a look at Array.slice(), which returns a new array without modifying the original.
So im recreating my ear training program with more effective coding so i can add on to it.
original i did.
//88 C8
var mp3Req88:URLRequest = new URLRequest("88.mp3");
var mp3_88:Sound = new Sound();
mp3_88.load(mp3Req88);
I basically got 88 sound files (each note of the piano) doing this code 88 times for each sound. with mathamatical equations made my ear training program.
Is there a simpler way to import these sounds in a loop of some sort so i dont have to do this 88x for the piano and however many times for the other instruments i will be including?
thus var i have tried things along the lines of below with failure
var i:int;
for (i = 0; i < 5; i++)
{
var pianoMP3Req+i:URLRequest=new URLRequest("piano/"i+"mp3");
var pianoMP3_+i:Sound=new Sound();
pianoMP3_+i.load(pianoMP3Req+i);
}
I am not sure if your strings concatenate correctly (if they correctly produce the valid filename.)
Try like this:
var i:int;
for (i = 0; i < 5; i++) {
var request = pianoMP3 + "" + i;
request:URLRequest=new URLRequest("piano/" + i + ".mp3");
var temp = pianoMP3 + "" + i;
temp:Sound=new Sound();
temp.load(request);
}
for both the request and the mp3. I don't have an environment to test it at the monent.
