So, I have a question. I'm currently working an an education program that teaches basics on cell organelles. I have lines pointing to each organelle, in which I want to have the user be able to input what each organelle name is (like a diagram). When the user has completed the work properly, I will display the next button.
However, in order to give the user the ability to proceed, I need a way of tracking whether or not a student's answers are correct. I am using parameter passing for this.
I would like to be able to return either true/false. If all answers are returned true, the user may advance. If even one answer is wrong, a message displays.
How do I use parameter passing to determine if a users answers are right/wrong? The textfields are in an array as well...
Here is the code.
Thanks!

You can check Array of TextFields vs Array of Arrays:
var Correct:Array = [
["nucleolus"],
["nucleus"],
["golgi body", "golgi apparatus"],
["mitochondria", "mitochondrion"]
];
var Answers:Array = [T1, T2, T3, T4];
// Returns true if all answers are correct.
function allCorrect():Boolean
{
for (var i:int = 0; i < Answers.length; i++)
if (!oneCorrect(Answers[i], Correct[i]))
return false;
return true;
}
// Returns true if answer is on the Array of correct answers.
function oneCorrect(source:TextField, target:Array):Boolean
{
return target.indexOf(source.text.toLowerCase()) > -1;
}
How can I make this work? I need to remove the word Button from the reference to reference the actual item that will be tinted. Thank you in advance.
disagreeButton.addEventListener(MouseEvent.ROLL_OVER, mouseRollOver);
contentMain.clickButton1.addEventListener(MouseEvent.ROLL_OVER, mouseRollOver);
function mouseRollOver(e:MouseEvent):void {
var c:Color = new Color();
c.setTint (0xFFFFFF, 1);
//the issue is this line:
this[e.target.name.replace( "Button", "" )].transform.colorTransform = c;
}
Now that I understand your problem, I would recommend the following.
Have separate methods for buttons in this, and in contentMain, and any others. Then access the objects by this[...] or contentMain[...], where appropriate.
disagreeButton.addEventListener(MouseEvent.ROLL_OVER, mainMouseRollOver);
contentMain.clickButton1.addEventListener(MouseEvent.ROLL_OVER, contentMainMouseRollOver);
function mainMouseRollOver(e:MouseEvent):void {
mouseRolloverLogic(this[e.target.name.replace( "Button", "" )];
}
function contentMainMouseRollOver(e:MouseEvent):void {
mouseRolloverLogic(contentMain[e.target.name.replace( "Button", "" )];
}
function mouseRolloverLogic(item:DisplayObject):void {
var c:Color = new Color();
c.setTint (0xFFFFFF, 1);
item.transform.colorTransform = c;
}
Add extra logic to the method you have.
if (this[...] != null) {
...
}else if (contentMain[...] != null) {
...
}
I want to leave the for each loop as soon as the boolean is set to true.
for each (xmlEvent in arEvents)
{
var xmlEvent:XMLList = XMLList(event);
if(xmlEvent.id == artistEvent.id)
{
boolExists = true;
}
}
I've tried break and such, but this all doesn't work.
Use break operator
for each (xmlEvent in arEvents)
{
var xmlEvent:XMLList = XMLList(event);
if(xmlEvent.id == artistEvent.id)
{
boolExists = true;
break;
}
}
Why not use the some() method? It'll handle all that for you.
boolExists = arEvents.some(
function (xmlEvent:*, index:int, arr:Array):Boolean {
return xmlEvent.id == artistEvent.id;
});
Note: The anonymous function is used only for brevity.
For clarity, the some() method only iterates over the array until the first item that returns true is reached, at which point iteration is terminated and the result (true) is returned.
Greetings,
This is my first post and I hope someone out there can help. I am an educator and I designed a quiz using Actionscript 3 (Adobe Flash) that is to determine all the different ways a family can have three children.
I have two buttons that enter either the letter B (for boy) or G (for girl) into an input text field named text_entry. I then have a submit button named enter_btn that checks to see if the entry into the input text is correct. If the input is correct, the timeline moves to the next problem (frame labeled checkmark); if it is incorrect the timeline moves to the end of the quiz (frame 62).
The following code works well for any particular correct single entry (ie: BGB). I need to write code in which all eight correct variations must be entered, but they can be entered in any order (permutation):
ie:
BBB,BBG,BGB,BGG,GBB,GBG,GGB,GGG; or
BGB,GGG,BBG,BBB,GGB,BGB,GGB,BGG; or
GGB,GGG,BBG,BBB,GGB,BGB,BGB,BGG; etc...
there are over 40,000 ways to enter these eight ways of having three children. Help!
baby_B.addEventListener(MouseEvent.CLICK, letterB);
function letterB(event:MouseEvent)
{
text_entry.appendText("B");
}
baby_G.addEventListener(MouseEvent.CLICK, letterG);
function letterG(event:MouseEvent)
{
text_entry.appendText("G");
}
enter_btn.addEventListener(MouseEvent.CLICK, check);
function check(event:MouseEvent):void {
var solution_S:Array=["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG "];
if(solution_S.indexOf(text_entry.text)>=0)
{
gotoAndStop("checkmark");
}
else
{
gotoAndPlay(62);
}
}
If you know the correct code, please write it out for me. Thanks!
You will just need to keep a little bit of state to know what the user has entered so far. One possible way of doing that is to have a custom object/dictionary that you initialize outside all your functions, so that it is preserved during the transitions between frames/runs of the functions:
var solutionEntered:Object = {"BBB":false, "BBG":false, /*fill in rest */ };
Then in your function check you can perform an additional check, something like:
function check(event:MouseEvent):void {
var solution_S:Array=["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG "];
if(solution_S.indexOf(text_entry.text)>=0) {
// We know the user entered a valid solution, let's check if
// then entered it before
if(solutionEntered[text_entry.text]) {
// yes they entered it before, do whatever you need to do
} else {
// no they haven't entered it, set the status as entered
solutionEntered[text_entry.text] = true;
}
// continue rest of your function
}
// continue the rest of your function
}
Note that this is not necessarily an optimal solution, but it keeps with the code style you already have.
Try this:
import flash.text.TextField;
import flash.events.MouseEvent;
import flash.display.Sprite;
var correctAnswers : Array = [ "BBB", "BBG", "BGB", "GBB", "BGG", "GGB", "GBG", "GGG" ];
var answersSoFar : Array;
var textField : TextField; //on stage
var submitButton : Sprite; //on stage
var correctAnswerCount : int;
//for testing
textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG,GGG";
//textField.text = "BGB,BBB,GGG,BBG,GBB,BGG,GGB,GBG,";
//textField.text = "BBB,BBG, BGB,GBB,BGG, GGB, GBG, GGG";
//textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG";
//textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG,GGG,BBG";
submitButton.addEventListener( MouseEvent.CLICK, onSubmit );
function onSubmit( event : MouseEvent ) : void
{
var answers : Array = getAnswersArray( textField.text );
answersSoFar = [];
correctAnswerCount = 0;
for each ( var answer : String in answers )
if ( answerIsCorrect( answer ) ) correctAnswerCount++;
if ( correctAnswerCount == correctAnswers.length ) trace( "correct" );
else trace( "incorrect" );
}
function getAnswersArray( string : String ) : Array
{
string = removeInvalidCharacters( string );
return string.split( "," );
}
function removeInvalidCharacters( string : String ) : String
{
var result : String = "";
for ( var i : int, len = string.length; i < len; i++ )
if ( string.charAt( i ) == "B" || string.charAt( i ) == "G" || string.charAt( i ) == "," )
result += string.charAt( i );
return result;
}
function answerIsCorrect( answer : String ) : Boolean
{
if ( answerIsADuplicate( answer ) ) return false;
else answersSoFar.push( answer );
if ( answerIsInListOfCorrectAnswers( answer ) ) return true;
return false;
}
function answerIsInListOfCorrectAnswers( answer : String ) : Boolean
{
if ( correctAnswers.indexOf( answer ) == -1 ) return false;
return true;
}
function answerIsADuplicate( answer : String ) : Boolean
{
if ( answersSoFar.indexOf( answer ) == -1 ) return false;
return true;
}
note that in the original code you pasted, you have an extra space in the last element of your correct answer list - "GGG " should be "GGG"
this works
baby_B.addEventListener(MouseEvent.CLICK, letterB);
function letterB(event:MouseEvent) {
text_entry.appendText("B");
}
baby_G.addEventListener(MouseEvent.CLICK, letterG);
function letterG(event:MouseEvent) {
text_entry.appendText("G");
}
var valid:Array = ["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG"];
enter_btn.addEventListener(MouseEvent.CLICK, check);
function check(event:MouseEvent):void {
var parts:Array = text_entry.text.split(/,\s*/g); // split the text into component parts
var dup:Array = valid.slice(); // copy the correct list
while(parts.length){ // run through each answer component
var part:String = parts.pop(); // grab the last one
part = part.replace(/(^\s+|\s+$)/g, ''); // strip leading/trailing white space
var pos:int = dup.indexOf(part); // is it in the list of correct answers?
if(pos != -1){ // if it is...
dup.splice(pos, 1); // then remove that answer from the list
}
}
if(dup.length == 0) { // if it's 0, they got all the correct answers
gotoAndStop("checkmark");
} else { // otherwise, they didn't get one or more correct answers
gotoAndPlay(62);
}
}

If you just want to know if they are different from each other, meaning by length, order or individual items, you can do the following, which first checks to see if the lengths are different, then checks to see if the individual elements are different. This isn't terribly reusable, it's left as an exercise for the reader to split this apart into cleaner chunks :)
public function foo(coll1:ArrayCollection, coll2:ArrayCollection):void {
if (coll1.length == coll2.length) {
for (var i:int = 0; i < coll1.length; i++) {
if (coll1[i].first != coll2[i].first || coll1[i].last != coll2[i].last) {
Alert.show("Different");
return;
}
}
}
Alert.show("Same");
}
/* elements need to implement valueOf
public function valueOf():Object{}
*/
public static function equalsByValueOf(
first:ArrayCollection,
seconde:ArrayCollection):Boolean{
if((first==null) != (seconde==null) ){
return false;
}else if(!first && !seconde){
return false;
}
if(first.length!=seconde.length){
return false;
}
var commonLength:int = first.length;
var dictionary:Dictionary = new Dictionary();
for(var i:int=0;i<commonLength;i++){
var item1:Object = first.getItemAt(i);
var item2:Object = seconde.getItemAt(i);
dictionary[item1.valueOf()]=i;
dictionary[item2.valueOf()]=i;
}
var count:int = 0;
for (var key:Object in dictionary)
{
count++;
}
return count==commonLength;
}
/* valueOf sample
* something like javaObject.hashCode()
* use non changing fields(recommended)
*/
public function valueOf():Object{
return "_"+nonChangeField1+"_"+nonChangeField2+"...";
}
I was going to say this.
if(collectionArray === collectionArray1)
But that wont work (not triple = signs). As === is used to see classes.
I would write a function called check if object exists in array.
Create an array to hold elements that are not found. eg notFound
in Collection1 go through all the element and see if they exist in Collection2, if an element does not exist, add it to the notFound array. Use the function your created in step1
Now check Collection2, if an element is not found add it to the notFound array.
There is no 5.
Dude, use the mx.utils.ObjectUtil... the creators of actionscript have already thought about this.
ObjectUtil.compare(collection1, collection2) == 0;
