my code is with AS3 ,( if-else) when i run it doesn't give me a mistake,but also doesn't give me the result of (if) that i want.
the ( tom) object has to be unvisible if touched another object called (food )else (tom) go back to ot's place
the idea is with ( drag and drop )
var hits = 0;
tom.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
tom.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
function mouseDownHandler(evt:MouseEvent):void {
var object = evt.target;
// we should limit dragging to the area inside the canvas
object.startDrag();
}
function mouseUpHandler(evt:MouseEvent):void {
var obj = evt.target;
var target = obj.dropTarget;
if (target == food && obj == tom) {
obj.visible=false;
} else {
obj.x=1051.05;
obj.y=135.05;
obj.stopDrag();
}
}
"When I run it doesn't give me a mistake, but also doesn't give me the result of if that I want."
That's because there is no error. You don't get a result because your IF condition is never reached. Think about example: if (obj == tom) Here what would ever make var obj be equal to var tom?
Solution:
I suspect food and tom are names, right? Try code to check by instance name...
function mouseUpHandler (evt:MouseEvent) :void
{
var obj = evt.target;
var target = obj.dropTarget;
if (target.name == "food" && obj.name == "tom")
{
obj.visible = false;
}
else
{
obj.x = 1051.05;
obj.y = 135.05;
obj.stopDrag();
}
}
I am using AS3, and i want to call function 'startMatchThree' which is in a MatchThree.as (external actionscript file) into the flahs main timeline actions.

when I put 'startMatchThree' in the actions tab in timeline, it is showing this error message:
1180: Call to a possibly undefined method startMatchThree.
SO how to solve this error!!
Thank you for the help!! :)
startMatchThree() is a method of the MatchThree class, so you need a reference to an instance of MatchThree. Is there a symbol on the timeline somewhere which is linked to the MatchThree class? Then you can do something like this, where "matchThree" is the instance name of the symbol:
matchThree.startMatchThree();
Are you instantiating the MatchThree class in code? Then you just need to use that code reference, something like this,:
var matchThree:MatchThree = new MatchThree();
matchThree.startMatchThree();
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.
How can I turn this basic function method into an Array and call to easily. Pretty much I am just comparing if objects have become false and then do something...but this just seems like a lot of code for something so easy. any ideas?

Something like the following should give you some ideas. I haven't tested the code you migt need to make some adjustments depending on your needs.
//put other movies clips in this array too.
var movieClips:Array = [level5_mc.let_b_mc,level5_mc.let_i_mc];
var movieClipFlags:Object = {
level5_mc.let_b_mc:[],
level5_mc.let_i_mc:[level5_mc.let_b_mc],
level5_mc.let_t_mc:[level5_mc.let_b_mc,level5_mc.let_i_mc]
//put other movie clips here too with the movie clips that need to be removed in the array
};
foreach(var mc:MovieClip in movieClips) {
mc.addEventListener(MouseEvent.CLICK,movieClipHit);
}
private function movieClipHit(e:MouseEvent) {
var mc:MovieClip = e.target as MovieClip;
if(readyToRemove(mc))
level5_mc.removeChild(mc);
else
trace("Can't remove yet.");
}
private function readyToRemove(mc:MovieClip):Boolean {
foreach(var mc:MovieClip in movieClipFlags[mc]) {
//if it has parent, it isn't removed yet.
if(mc.parent)
return false;
}
return true;
}
Hope it helps.
I am creating a "good" "bad" array to display on screen which i can later use simple if statements to do something upon if the player has collided with the "good" "bad" objects.
I cant get the objects to randomly generate on screen with the following code.
// Create and Set good/bad random Word objects
public function newObject(e:Event)
{
var goodObjects:Array = ["WordObject1"];
var badObjects:Array = ["WordObject2"];
if (Math.random() < .5)
{
var r:int = Math.floor(Math.random()*goodObjects.length);
var classRef:Class = getDefinitionByName(goodObjects[r]) as Class;
var newObject:MovieClip = new classRef();
newObject.typestr = "good";
} else
{
r = Math.floor(Math.random()*badObjects.length);
classRef = getDefinitionByName(badObjects[r]) as Class;
newObject = new classRef();
newObject.typestr = "bad";
}
newObject.x = Math.random();
newObject.y = Math.random();
addChild(newObject);
objects.push(newObject);
placeWords();
}
// create random Word objects
public function placeWords() {
objects = new Array();
for(var i:int=0;i<numWordObjects;i++) {
// loop forever
while (true) {
// random location
var x:Number = Math.floor(Math.random()*mapRect.width)+mapRect.x;
var y:Number = Math.floor(Math.random()*mapRect.height)+mapRect.y;
// check all blocks to see if it is over any
var isOnBlock:Boolean = false;
for(var j:int=0;j<blocks.length;j++) {
if (blocks[j].hitTestPoint(x+gamesprite.x,y+gamesprite.y)) {
isOnBlock = true;
break;
}
}
// not over any, so use location
if (!isOnBlock) {
newObject.x = x;
newObject.y = y;
newObject.gotoAndStop(Math.floor(Math.random()*1)+1);
gamesprite.addChild(newObject);
objects.splice(newObject);
break;
}
}
}
}
i get the following errors:
1119: Access of possibly undefined property x through a reference with static type Function.
1119: Access of possibly undefined property y through a reference with static type Function.
1067: Implicit coercion of a value of type Function to an unrelated type flash.display:DisplayObject.
Try renaming var x and var y to something else. Those are public properties in any class that extends as a display object (Sprite/MovieClip/Shape).
