I am following a tutorial on building a rhythm game in as3 here, and I am very new to the language. On running the swf, I get the following error in the output:
ReferenceError: Error #1069: Property keyCode not found on flash.display.Shape and there is no default value.

I have tried some previous solutions posted to the same error, but I have not been able to resolve the issue.
Here is the source code:

Can someone tell me why this error is occurring? Thank you.
While iterating numChildren, it's necessary to check the object is an arrow or not.
Maybe you can distinguish it by having keyCode property or not.
Try to use Object.hasOwnProperty(property name) method.
if (target.hasOwnProperty("keyCode")){
// access target.keyCode here.
}
Or this might works too.
if (target is arrowLeft || target is arrowUp || target is arrowDown || target is arrowRight){
// the target should be arrow class
// access target.keyCode here.
}
//this for loop will be used for the hit testing
for(var i:int = 0;i<numChildren;i++){
var target:Object = getChildAt(i);
if (target.hasOwnProperty("keyCode")){ // If the object is an arrow, that object should has keyCode property.
if(target.keyCode != null && target.hitTestObject(mcReceptor)){//if the object is an arrow and the receptor is touching it
if(target.keyCode == 68){//if left arrow
touchLeft = true;
} else if(target.keyCode == 70){//if up arrow
touchUp = true;
} else if(target.keyCode == 74){//if down arrow
touchDown = true;
} else if(target.keyCode == 75){//if right arrow
touchRight = true;
}
}
}

I make an mc object. this object can move right and left with keyboard. details are when I push rightkey it moves to right position in certain coordinate and when I push leftkey it moves to left position in certain coordinate. I want the object just move in 3 position.
for this case, I tried to use array.
var P:Array = [new Point(100, 300), new Point(275, 300), new Point(425, 300)];
var M:Array = [Kotak];
but when I input them to my code, it doesn't work and no error appears. anyone can tell me where's my fault?
this's my full code :
import flash.geom.Point;
//gerak pemain
var pemainKanan:Boolean = false;
var pemainTengah:Boolean = false;
var pemainKiri:Boolean = false;
//kecepatan
var kecepatanPemain:int = 20;
//Array object acak
var P:Array = [new Point(100, 300), new Point(275, 300), new Point(425, 300)];
var M:Array = [Kotak];
//var P:Point = new Point(100, 300);
Kotak.addEventListener(KeyboardEvent.KEY_UP, k);
function k(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT){
pemainKanan = false;
}
if(e.keyCode == Keyboard.LEFT){
pemainKiri = false;
}
}
Kotak.addEventListener(KeyboardEvent.KEY_DOWN, kk);
function kk(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT){
pemainKanan = true;
}
if(e.keyCode == Keyboard.LEFT){
pemainKiri = true;
}
}
Kotak.addEventListener(Event.ENTER_FRAME, eframe);
function eframe(e:Event):void{
if(pemainKanan == true){
//pemain.gotoAndStop("right");
Kotak.x = P[0];
}
else if(pemainKiri == true){
//pemain.gotoAndStop("left");
Kotak = P[1];
}
}
Can you please explain that in detail? From what I've read I understand that you want a MovieClip to move to three positions. For example if it is on position0 and right is pressed it should move to position1, but if it's in position1 it should move to position2 and the other way around with left button. Is this what you want to do? If it is there is no need for the ENTER_FRAME event, since all it can be done maybe with an index.
Kotak.addEventListener(KeyboardEvent.KEY_DOWN, kk);
var index:int=0;
function kk(e:KeyboardEvent):void{
if(e.keyCode == Keyboard.RIGHT){
if(index==0){
Kotak.x = P[1];
}
else{
if(index==1){
Kotak.x = P[2];
}
}
index++;
}
if(e.keyCode == Keyboard.LEFT){
if(index==2){
Kotak.x = P[1];
}
else{
if(index==1){
Kotak.x = P[0];
}
}
index--;
}

I have this flash game coded with AS3. It works on the first round. When you die, the program will loop it back to the game frame in which a couple or errors occur. One. the dead characters from last round still remain still. Two. The speed doubles everytime. Why????
I create a resetEverything() function to reset all variables, remove Event Listeners and a clear.graphics()
Why doesn't anything work?

Please help!
This is hard to explain.
My aim is to spawn sheep(symbol) each time i click placed according to the mouse's X/Y axis... . I want it to spawn copies of the sheep BUT i also want each copy to be a different image.. (each time the mouse is clicked, it will change the image inside the sheep's symbol (placed on different frames).
If anyone can help I will appreciate it so much!
This is the code:
stage.addEventListener (MouseEvent.CLICK, makeABox);
var i:Number = 1;
function makeABox(e:Event):void {
var newSheep:myMC = new myMC();
addChild(newSheep);
newSheep.x = stage.mouseX;
newSheep.y = stage.mouseY;
i++;
}
var numPressed:Number = 0;
stage.addEventListener(MouseEvent.CLICK, countUp);
function countUp(evt:MouseEvent):void {
numPressed++;
if (numPressed == 1) {
sheep.gotoAndPlay(1);
}
else if (numPressed == 2) {
sheep.gotoAndPlay(2);
}
else if (numPressed == 3) {
sheep.gotoAndPlay(3);
}
else if (numPressed == 4) {
sheep.gotoAndPlay(4);
}
else if (numPressed == 5) {
sheep.gotoAndPlay(5);
}
else if (numPressed == 6) {
sheep.gotoAndPlay(6);
}
else if (numPressed == 7) {
sheep.gotoAndPlay(7);
}
if(numPressed >= 7) numPressed = 0;
}
Replace all the code you posted in your question with this:
stage.addEventListener (MouseEvent.CLICK, addSheep);
var sheepCounter:int = 1;
function addSheep(event:MouseEvent):void {
//create new sheep
var newSheep:myMC = new myMC();
//position it at mouse click
newSheep.x = stage.mouseX;
newSheep.y = stage.mouseY;
//set frame of sheep to display
newSheep.gotoAndStop(sheepCounter);
//add sheep to display list
addChild(newSheep);
//update counter
sheepCounter++;
if (sheepCounter==8)
{
sheepCounter = 1;
}
}
Had a look for this but nothing seemed clear at the moment I have a script which will only play if the frame is the currentFrameLabel or rewind.
However in order for it not to go one frame too far I need to be able to stop it on the frame before the change not on the change.
Or am I just going about this the wrong way?
For example:
Frame 10 Label: Up
Frame 12-36 Label: Idle Loop
Frame 37 Label: Hand Up
I need it to only play from frames 12 to 36 but at the moment it plays from frames 12-37.
var reverse:Boolean = false;
var robotlabel:String = 'Up/Down';
what.addEventListener(MouseEvent.MOUSE_OVER, botAction);
what.addEventListener(MouseEvent.MOUSE_OUT, botAction2);
function botAction(evt:MouseEvent):void{
reverse = false;
robotlabel = 'Hand up/Down';
robot.gotoAndPlay('Hand up/Down');
robot.addEventListener(Event.ENTER_FRAME,run);
}
function botAction2(evt:MouseEvent):void{
reverse = true;
robot.prevFrame();
}
function run(e:Event):void{
trace("label:" + robotlabel);
trace("current" + robot.currentFrameLabel);
if(robot.currentFrameLabel != robotlabel && robot.currentFrameLabel != null){
trace("stoooooppppp");
robot.stop();
}
if(reverse == true && currentFrameLabel==robotlabel){
robot.prevFrame();
trace("reversing!");
}else if(reverse == false && (currentFrameLabel==robotlabel || robot.currentFrameLabel == null)){
robot.nextFrame();
}else{
trace("destroy");
reverse = false;
robot.stop();
robot.removeEventListener(Event.ENTER_FRAME,run);
}
}
There is not a "nextFrameLabel" property as such in as3, however you can get an array of all the frame labels and numbers in your target movieclip using the currentLabel property of the MovieClip and work it out from there, since you know the currentFrame at all times.
Quick example from the docs:
import flash.display.FrameLabel;
var labels:Array = mc1.currentLabels;
for (var i:uint = 0; i < labels.length; i++)
{
var label:FrameLabel = labels[i];
trace("frame " + label.frame + ": " + label.name);
}
In case this is useful to anybody else I solved it by looping through each frame and then storing the corresponding label to the frame so it can later be checked against.
for (i = 1; i < robot.totalFrames; i++)
{
for (var n:uint = 0; n < this.robolabels.length; n++)
{
if(this.robolabels[n].frame == i){
newLabel = this.robolabels[n].name
}
}
this.roboframes[i] = newLabel;
}
I am a student working on a project with flash. I am simply trying to make a flash game using Actionscript 3 in Adobe Flash CS5. Everything is working fine, i can walk and jump, but I want the game to restart if the Main character touches an object and dies (like spikes in a pit). I have a main menu in frame 1 and the first level on frame 2. The main character is called "player_mc" and the object that kills him is called "dies". Help and tips is very much appreciated.

If I understand this right, when you die, you want to restart the level. To do this, you could save all your initial variables like player position, floor position, etc in an array, then on death, restore those variables to their corresponding object. However, when you get more complex and have lots and lots of objects, it could become tricky.
A simpler solution is to display a death screen of some sorts on another frame (lets call it frame 3) when you hit the dies object, and on that death screen when you press a restart button or after a certain time delay, it then goes back to frame 2 and restarts the level.
Example:
Put this in your moveThePlayer function:
if(dies.hitTestPoint(player_mc.x, player_mc.y, true))
{
// remove all the event listeners
player_mc.removeEventListener(Event.ENTER_FRAME, moveThePlayer);
stage.removeEventListener(KeyboardEvent.KEY_DOWN, PressAKey);
stage.removeEventListener(KeyboardEvent.KEY_UP, ReleaseAKey);
gotoAndStop(3); // this has your "dead" screen on it.
}
And on frame 3, have something like:
import flash.events.MouseEvent;
retry_button.addEventListener(MouseEvent.CLICK, retry);
function retry(e:MouseEvent) {
retry_button.removeEventListener(MouseEvent.CLICK, retry);
// back to the level
gotoAndStop(2);
}
You could also do something like storing a variable on which frame you want to go back to, so you have a single retry frame which can go to whatever level you were just on.
A good habit that you should develop is having an endGame() or similar method that you update as you work on the game.
For example:
function endGame():void
{
// nothing here yet
}
Now lets say you create a player. The player is initially set up like this:
player.health = 100;
player.dead = false;
You'll want to update your endGame() method to reflect this.
function endGame():void
{
player.health = 100;
player.dead = false;
}
Got some variables related to the game engine itself?
var score:int = 0;
var lives:int = 3;
Add those too:
function endGame():void
{
player.health = 100;
player.dead = false;
score = 0;
lives = 3;
}
Now endGame() should reset the game back to its original state. It's much easier to work this way (as you code the game) rather than leaving it until last and trying to make sure you cover everything off, which is unlikely.
