How to create a sequence of clicks in ActionScript? - actionscript-3

Question

I am creating a puzzle in which the player have to click on the buttons on the right order or sequence to go to the next level (Scene 2 for example). I don't know how to do it. If any one have any idea to how to achieve this in Action Script.
Thank you
Scene 1:
enter image description here
each number is a button. Now the player has to click in the right order or sequence (1 2 3 4 5 6 7 8) to open the next level (Scene 2)
var checkString:String = "";
//Create event listeners and their functions.
btn1.addEventListener(Mouse.CLICK, oneClick);
btn2.addEventListener(Mouse.CLICK, twoClick);
btn3.addEventListener(Mouse.CLICK, threeClick);
btn4.addEventListener(Mouse.CLICK, fourClick);
btn5.addEventListener(Mouse.CLICK, fiveClick);
btn6.addEventListener(Mouse.CLICK, sixClick);
btn7.addEventListener(Mouse.CLICK, sevenClick);
btn8.addEventListener(Mouse.CLICK, eightClick);
function oneClick(evt:Event):void
{
//In each event listener function, add a letter or
//string to the checkString variable.
checkString += "on";
//Then, see if the string matches or not.
check();
}
function twoClick(evt:Event):void
{
checkString += "tw";
check();
}
function threeClick(evt:Event):void
{
checkString += "th";
check();
}
function fourClick(evt:Event):void
{
checkString += "fo";
check();
}
function fiveClick(evt:Event):void
{
checkString += "fi";
check();
}
function sixClick(evt:Event):void
{
checkString += "si";
check();
}
function sevenClick(evt:Event):void
{
checkString += "se";
check();
}
function eightClick(evt:Event):void
{
checkString += "ei";
check();
}
//If the proper sequence is one, two, three, four, five, six, seven, eight the string would read "ontwthfofisiseei".
function check():void
{
if(checkString == "ontwthfofisiseei")
{
//Clear the checkString for convenience before going on.
clearString();
//CODE TO GO TO NEW FRAME
gotoAndPlay(1, "Scene 3");
}
}
function clearString():void
{
//You will want to have a function for clearing the string.
//This is especially useful if you have a button for "start over."
checkString = "";
}
this the code i used before but it show error in the listener and it doesn't. work

To answer your updated question:
Your error is likely that Mouse.CLICK should be MouseEvent.CLICK.
Your other error is telling you that there is no scene called "Scene 3"
Let's assume you have 8 MovieClips (or buttons) that are on a timeline in Flash/Animate.
One (of many) ways to accomplish this would be the following:
Give each of those buttons an instance name. To make for less code, lets give them the name btn + their respective correct order number - so btn1, btn2, btn3 etc.
You'll need to add a click listener to each button, so they can have something happen when they are clicked.
You could do this 8 times (one for each button): btn1.addEventListener(MouseEvent.CLICK, buttonClick); but to make things simpler, you can just iterate through all the objects on the timeline and add the listener to each object whose name starts with "btn":
var totalBtns:int = 0; //create a var to store how many buttons there are
//loop through each child of the current timeline
var i:int = numChildren;
while(i--){
//if the child's name starts with 'btn'
if(getChildAt(i).name.indexOf("btn") == 0){
//add the click listener
getChildAt(i).addEventListener(MouseEvent.CLICK, buttonClick,false,0,true);
totalBtns++; //increase the total buttons variable by 1
}
}
This also means less work later if you add/remove buttons
You need a way to track when a button was clicked. To accomplish this, we'll use an array.
var clickArray:Array = []; //this creates a new array
//When a button is clicked, you add it to this array
lets create the function that is called when a button is clicked:
function buttonClick(e:Event):void {
//add the item that was just clicked (represented by the event's currentTarget property) to the array
//so if btn1 was just clicked, btn1 would be e.currentTarget
clickArray.push(e.currentTarget);
//now disable the button so it can't be clicked anymore
SimpleButton(e.currentTarget).enabled = false;
//check if all button have been clicked
if(clickArray.length == totalBtns){
//lets go through every item in the array, and see if it's in the right order
var ctr:int = 0; //a counter to keep track of the expected next number var i:int = 0; //iterator for the for loops
for(i=0;i<clickArray.length;i++){
//lets convert everything after the 3rd character of the name to a number - so for btn1, that would be 1
if(parseInt(clickArray[i].name.substring(3)) == ctr + 1){
ctr++; //increment the counter to the next expected number
}else{
break; //leave the for loop early since a click was out of place
}
}
//if the correct order was achieved
if(ctr == totalBtns){
nextScene(); //or however you continue
}else{
//the correct order was NOT acheived
//make all the buttons clickable again
for(i=0;i<clickArray.length;i++){
SimpleButton(clickArray[i]).enabled = true;
}
//reset the array
clickArray = [];
//probably want to tell the user to try again
}
}
}
