The drag and drop works, however, I have no idea how to create an if statement that goes to the next scene when all movieclips have been placed on the target.
I've tried placing the instance names in an if statement with the hittestobject however, no luck.

for each(var lemonMC:MovieClip in lemons)
{
lemonMC.buttonMode = true;
lemonMC.addEventListener(TouchEvent.TOUCH_BEGIN, pickobject);
lemonMC.addEventListener(TouchEvent.TOUCH_END, dropobject);
lemonMC.startX = lemonMC.x;
lemonMC.startY = lemonMC.y;
}
var fl_DragBounds:Rectangle = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
function pickobject(event:TouchEvent):void
{
event.target.startTouchDrag(event.touchPointID, false, fl_DragBounds);
event.target.parent.addChild(event.target);

if(event.target.hitTestObject(target_mc)){
event.target.buttonMode = false;
event.target.x = target_mc.x;
event.target.y = target_mc.y;
event.target.visible = false;

How about adding a counter that is equal to number of objects to drag, then every time you drop object (and detect if it was on target) you decrements the counter and at the end of the function you check if it's 0?
An easy way to do this would be to remove your lemons/melons from their arrays when they pass the hit test. Then check if each array is empty and continue to the next scene should that be the case.
You can actually reduce redundant code and use the same function (dropobject) for both lemons and melons.
function dropobject(event:TouchEvent):void {
//Figure out which array this belongs to (is it a lemon or a melon)
var array:Array; //the array the dropped item belongs to
var hitMC:MovieClip; //the hit object for the lemon or melon
if(lemons.indexOf(event.currentTarget) > -1){ //if the lemon array contains the currentTarget
array = lemons;
hitMC = target_mc;
}else{
array = melons;
hitMC = target_null;
}
if(event.currentTarget.hitTestObject(hitMC)){
event.currentTarget.buttonMode = false;
event.currentTarget.x = hitMC.x;
event.currentTarget.y = hitMC.y;
event.currentTarget.visible = false;
//remove the item from it's array
array.removeAt(array.indexOf(event.currentTarget));
//check if there are any items left
if(lemons.length < 1 && melons.length < 1){
//both arrays are empty, so move on
play(); //or however you want to move on
}
}
}
Getting more advanced, a better way to do this would be to make a base class for your lemons, melons and anything else you want to drag in the future. Then you can add the dragging functionality into that base class and add properties for the hit target and an event for when it's hit it's target. This would give you one code base that can be easily applied to any library object.
I am using this code and getting the Error Message "1180: Call to a possibly undefined method DirectBlock." At Source: "block = new DirectBlock(lvlArray[i],(i-row*22)*25,row*25);"

Off course, you got no class called DirectBlock and your class EmptyBlock has no parameters in the constructor (in case you wanted to use the second class and not the first).
I'm trying to take this very simple "game" and give it three save/load slots. Following a separate tutorial I can make it work with a single save slot but once I try adding more, it gives me the following error message.
1046:Type was not found or was not compile-time constant: save2.
1046:Type was not found or was not compile-time constant: save3.
I am new to actionscript 3 so I'm sure I'm being very newbish but I have tried to figure this out for quite some time now but just can't seem to. The whole thing is controlled by buttons already placed on the scene. I appreciate any help I can get.
The code:
import flash.net.SharedObject;
var saveDataObject:SharedObject;
var currentScore:Number = 0
init();
function init():void{
btnAdd.addEventListener(MouseEvent.CLICK, addScore);
btnSave1.addEventListener(MouseEvent.CLICK, save1);
btnSave1.addEventListener(MouseEvent.CLICK, saveData);
btnSave2.addEventListener(MouseEvent.CLICK, save2);
btnSave2.addEventListener(MouseEvent.CLICK, saveData);
btnSave3.addEventListener(MouseEvent.CLICK, save3);
btnSave3.addEventListener(MouseEvent.CLICK, saveData);
btnLoad1.addEventListener(MouseEvent.CLICK, save1);
btnLoad1.addEventListener(MouseEvent.CLICK, loadData);
btnLoad2.addEventListener(MouseEvent.CLICK, save2);
btnLoad2.addEventListener(MouseEvent.CLICK, loadData);
btnLoad3.addEventListener(MouseEvent.CLICK, save3);
btnLoad3.addEventListener(MouseEvent.CLICK, loadData);
}
function save1(e:MouseEvent):void{
saveDataObject = SharedObject.getLocal("savefile1");
}
function save2(e:MouseEvent):void{
saveDataObject = SharedObject.getLocal("savefile2");
}
function save3(e:MouseEvent):void{
saveDataObject = SharedObject.getLocal("savefile3");
}
function addScore(e:MouseEvent):void{
currentScore += 1;
updateScoreText();
}
function saveData(e:MouseEvent):void{
saveDataObject.data.savedScore = currentScore;
trace("Data Saved!");
saveDataObject.flush();
trace(saveDataObject.size);
}
function loadData(e:MouseEvent):void{
currentScore = saveDataObject.data.savedScore;
updateScoreText();
trace("Data Loaded!");
}
function updateScoreText():void
{
txtScore.text = ("Score: " + currentScore);
trace("Score text updated");
}
I tried your code and it works like a charm...
Anyways, I've made a simpler version that doesn't use so many functions and Events.
Here is a pure AS3 version of it (just save it as Test.as3 and use as Document Class in Flash), but you can copy the content of the Test() method and paste in a action frame.

i have a problem with my as3 code,
i try to link a movie clip to different scene (quiz scene).
so,i have 2 quiz in total, first quiz is using external script (as)
And the second quiz have the same script like first quiz, but i placed the action script inside fla. and it had different xml.
but then this error message appeared:

the first quiz played perfectly with that code,
and i have no clue why this error appeared,
i'm beginner in as3 so i'm still lack in many ways,
can anyone help me,?
i really apreciate it.. :)
Are you sure that you're parsing a non-null TextFormat instance as the second argument of createText()?
The error means that you're supplying a null value for tf:TextFormat.
Unless I am missing something, your issue is here:
messageField2 = createText("Loading Questions...",questionFormat,gameSprite,0,50,550);
&
messageField = createText("Tap Untuk Memulai",scoreFormat,gameSprite,-10,250,500);
I see questionFormat2 and scoreFormat2 are instantiated, but I never see a questionFormat or scoreFormat. Your error says that the defaultTextFormat (or TextFormat supplied using setTextFormat(), for future reference), cannot be null. Null means that the object has not been instantiated/created yet. questionFormat and scoreFormat are never instantiated. Hell, their variables do not even exist. If you were using a proper development IDE (FlashBuilder, FlashDevelop, etc), you'd never be able to compile this code.
Switch those two lines to use the correct formats and you should be fine.

This is regarding a drag n drop game. A particular object name will be displayed to the user then the user has to drag n drop the correct image to specified position and once the task is completed it will dynamically navigate to the next scene. For that i have used the timer class. I am getting this error in the scene 2 but in scene 1 the code runs perfectly.
The naming conventions are all correct but i still get the following error,
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Can someone help me with this.
Your locally declared method "doTask" is removed right after the execution of the mouse listener. You should either create an anonymous inline listener
var setTimer:Timer = new Timer(1000,60);
setTimer.addEventListener(TimerEvent.TIMER, function(event:TimerEvent):void {
gotoAndStop(1,"Scene 2");
setTimer.stop();
});
setTimer.start();
Some like to do so but I am not a big fan of inline declaration. I would create a real method in my class as a listener.
private var setTimer:Timer;
function stage_onMouseUpClipB(event:MouseEvent):void {
...
setTimer = new Timer(1000,60);
setTimer.addEventListener(TimerEvent.TIMER,doTask);
...
}
function doTask(event:TimerEvent):void {
gotoAndStop(1,"Scene 2");
setTimer.stop();
}
