I have a movie clip (tempEnemyA) in an array (enemiesA). These enemies fall down and the player kills them by clicking on them. The higher the score = the faster the enemies drop. For some reason though, when there are a lot of enemies on stage, they start to become very hard to click. This is the code inside the tempEnemyA:
import flash.events.MouseEvent;
import flash.display.MovieClip;
import fl.motion.Animator;
import flash.events.*;
import flash.utils.setTimeout;
this.addEventListener(MouseEvent.CLICK, killM);
this.dead3 = false;
function killM(event:MouseEvent):void
{
this.dead3=true;
this.mouseChildren=false
gotoAndPlay(31);
this.removeEventListener(MouseEvent.CLICK, killM);
flash.utils.setTimeout(removeSelfM,2000);
}
function removeSelfM():void
{
this.parent.removeChild(this);
this.addEventListener(MouseEvent.CLICK, killM);
}
this.dead3 activates this condition inside the stage layer:
if (tempEnemyA.dead3)
{
scoreA++;
scoreA++;
AntLevel.scoreA_txt.text = String(scoreA);
enemiesA.splice(g,1);
}
As a whole this is the whole code that spawns the enemies:
function makeEnemiesA():void
{
var chance:Number = Math.floor(Math.random() * 150);
if (chance <= + levelA)
{
//Make sure a Library item linkage is set to Enemy...
tempEnemyA = new Mosquito();
tempEnemyA.speed = 2
//Math.random(); gets a random number from 0.0-1.0
tempEnemyA.x = Math.round(Math.random() * 550);
addChild(tempEnemyA);
enemiesA.push(tempEnemyA);
tempEnemyA.speed = enemyBaseSpeed3 + ((levelA - 1) * speedLevelInc3);
if (tempEnemyA.speed > MAX_SPEED3)
{
tempEnemyA.speed = MAX_SPEED3;
}
}
}
function moveEnemiesA():void
{
var tempEnemyA:MovieClip;
for (var g:int =enemiesA.length-1; g>=0; g--)
{
tempEnemyA=enemiesA[g];
if (tempEnemyA.dead3)
{
scoreA++;
scoreA++;
AntLevel.scoreA_txt.text = String(scoreA);
enemiesA.splice(g,1);
}
else // Enemy is still alive and moving across the screen
{
//rotate the enemy between 10-5 degrees
tempEnemyA.rotation += (Math.round(Math.random()*.4));
//Find the rotation and move the x position that direction
tempEnemyA.x -= (Math.sin((Math.PI/180)*tempEnemyA.rotation))*tempEnemyA.speed;
tempEnemyA.y += (Math.cos((Math.PI/180)*tempEnemyA.rotation))*tempEnemyA.speed;
if (tempEnemyA.x < 12)
{
tempEnemyA.x = 12;
}
if (tempEnemyA.x > stage.stageWidth - offset2)
{
tempEnemyA.x = stage.stageWidth - offset2;
}
if (tempEnemyA.y > stage.stageHeight)
{
removeEnemyA(g);
livesA--;
AntLevel.livesA_txt.text = String(livesA);
}
}
}
}

I have 2 issues in this code.
The first is:
5006: An ActionScript file can not have more than one externally visible definition: Sprayer, bugs
I've put multiple Actionscripts together to create this, i've seperated out the classes and am hoping to play this on a frame from a symbol.
and the second relates to:
Error #1006: hitTestObject is not a function
For this i'm trying to get the aagun/Sprayer to lose health then lives if the bugs touch it, but i'm not sure why it's saying it's not a function. Am I using the wrong words?

5006: An ActionScript file can not have more than one externally visible definition: Sprayer, bugs
As it says exactly: you can't have more than one public definition in a file. You have to either split the code to several files or move definitions, that you don't need public, out of the package.
This would be Ok in one file:
package
{
import flash.display.MovieClip;
// public is the default access modifier
public class Test1 extends MovieClip
{
public function Test1()
{
trace("test1");
var t2:Test2 = new Test2();
var t3:Test3 = new Test3();
}
}
}
// Test2 and Test3 are defined outside of the package, otherwise it wouldn't compile.
// These definitions will only be visible to code in this file.
import flash.display.MovieClip;
class Test2 extends MovieClip
{
public function Test2()
{
trace("test2");
}
}
class Test3 extends MovieClip
{
public function Test3()
{
trace("test3");
}
}

Error #1006: hitTestObject is not a function
This usually means that hitTestObject() is not defined on the object (or it's ancestors) you are trying to call it from (although there could be different kinds of errors for that).
hitTestObject() is accessed in two ways in your code: airplanes.hitTestObject() and bullets[bulletNum].hitTestObject(). You will have to debug your code to see what is actually airplanes and bullets[bulletNum], what types they are and whether they inherit hitTestObject() method. You could at least trace() them.
I'm trying to make simple shooting game with Fiat Multipla falling up to bottom of the screen. I have created function to generate falling multipla and within this function I have a problem.
The main issue is that after change of multideath status to 1 "Death" function does nothing even if It is kept with ENTER_FRAME. Child becomes invisible as I implemented it in multipla movieclip, but even after response from there with Death = 1, nothing happens.
I'm new to all this, I've met and solved few issues during programming, but here's my brickwall for now. Code's either failing completely or I don't know something that's obvious. As I said, I'm newbie.
Thanks a lot for help!
Here's the function:
import flash.events.Event;
import flash.desktop.NativeApplication;
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
Mouse.hide();
var velocity = 0;
var ammo = 6;
LGUI.LGUIammo.gotoAndStop(6);
var counter = 0;
function multiplarain()
{
var x1 = Math.ceil(Math.random() * 280);
var y1 = -200;
var random:Multipla = new Multipla();
var life = 265;
var multideath = 0;
random.x = 100 + x1;
random.y = y1
addChild(random);
random.gotoAndStop(1);
setChildIndex(random, +1);
addEventListener(Event.ENTER_FRAME, Death);
function Death(event:Event):void
{
if(multideath >= 1)
{
removeEventListener(Event.ENTER_FRAME, Death);
removeChild(random);
}
}
addEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler);
function fl_EnterFrameHandler(event:Event):void
{
if(random.y >= 680)
{
removeEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler)
removeChild(random);
trace("rofl");
}
}
random.addEventListener(Event.ENTER_FRAME, fl_AnimateVertically);
function fl_AnimateVertically(event:Event)
{
velocity = velocity + 0.000035;
random.y += 1.5 + velocity;
}
random.addEventListener(TouchEvent.TOUCH_TAP, fl_TapHandler);
function fl_TapHandler(event:TouchEvent):void
{
counter = counter + 1;
ammo -= 1;
}
if(ammo == 6)
{

}

{
LGUI.LGUIammo.gotoAndStop(3);
}
if(ammo == 2)
{
LGUI.LGUIammo.gotoAndStop(2);
}
if(ammo == 1)
{
LGUI.LGUIammo.gotoAndStop(1);
}
if(ammo <= 0)
{
LGUI.LGUIammo.gotoAndStop(7);
}
HGUI.saved.text = counter;
this.addEventListener( Event.ENTER_FRAME, handleCollision)
var kucyk = LGUI.LGUIlife.lifeitself;
function handleCollision(e:Event):void
{
if (random.hitTestObject(LGUI))
{
kucyk = LGUI.LGUIlife.lifeitself;
kucyk.width -= 0.1;
}
/*if (kucyk.width == 0.75)
{
trace("cycki");
NativeApplication.nativeApplication.exit();
}*/
}
}
and here's multipla's movieclip in library code:
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
this.addEventListener(TouchEvent.TOUCH_TAP, fl_TapHandler2);
function fl_TapHandler2(event:TouchEvent):void
{
this.gotoAndPlay(2);
}
addEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler);
function fl_EnterFrameHandler(event:Event):void
{
if(this.currentFrame == 60)
{
this.visible = false;
MovieClip(root).multideath = 1;
trace(MovieClip(root).multideath);
removeEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler);
removeEventListener(Event.ENTER_FRAME, fl_TapHandler2);
}
}
it's been like 10 years since I last time worked with AS2 but I'd guess that this Multipla sets the multideath property in the wrong place. If i remember corrctly, root is the top-most level (your application). So if your first code is not on the main timeline but in a movieclip that is on the main timeline it won't work. Try to put a trace into the Death function to see if the multideath is really changing there:
trace(multideath);
try this in the multipla code:
parent.multideath = 1;
instead of
MovieClip(root).multideath = 1;
And I'm asking myself why do you need so many enter frame listeners? You can have just one and combine all animations in one function.
Also you don't need to check for multideath on every frame, just remove the movieclip in a separate function:
function removeMultipla():void
{
removeChild(random);
}
Just call this function from your Multipla instead of setting the multideath property:
parent.removeMultipla();
I was trying to add a gameover screen with a restart button for my game.I had placed the restart button at frame 22.When my player dies it goes to frame 22 and i'm able to restart the game on clicking the button,but this message gets looped in the output area.Please help me how i can correct this issue.
Issue is not there when i remove the line
gotoAndPlay(22);
at Frame 17,but without that i will not get the desired functionality.
Please find my code below

}
That error means that you are trying to call a method on a null object, meaning one of the objects you are using on frame 22 doesn't actually exist at that moment.
The likely candidates for the offending variable are foutput, btn_playagain, and btnback3. Check to make sure that they are on the stage at frame 22, and are spelt correctly.
You use output.text on frame 17, are you sure that it should be foutput.text on frame 22?
I'm working on a Flash game for an assignment. It's a pretty standard missile defense-type game, with a rotating missile launcher in the center firing up at passing bombers above. The missiles and bombers are functioning correctly by themselves, but I'm running into a problem when I try to get the two to interact. Specifically, when a missile hits a bomber, I want the specific instances of that missile and that bomber to be removed from the screen and have their respective event listeners removed, but everything I've tried has failed and I can't seem to figure out just how to do it.
Here are the Main, Bomber, and Missile classes I'm working with:

}

import flash.display.Stage;
import flash.display.MovieClip;
public class Bomber extends MovieClip {
var stageInstance:Stage;
var randomNumber:Number = Math.round(Math.random() * 1);
public function Bomber(stageInstance:Stage):void {
this.stageInstance = stageInstance;
if(randomNumber == 1) {
x = -39;
y = (Math.random() * 120) + 30;
}
else if(randomNumber == 0) {
scaleX *= -1;
x = 679;
y = (Math.random() * 120) + 30;
}
}
public function fly():void {
if(randomNumber == 1) {
x = x + 4;
}
else if(randomNumber == 0) {
x = x - 4;
}
if(x > 680 || x < -40) {
this.parent.removeChild(this);
}
}
}
}
The Missile Class:
package {
import flash.display.Stage;
import flash.display.MovieClip;
public class Missile extends MovieClip {
var stageInstance:Stage;
var velocityX:Number;
var velocityY:Number;
var speed:Number = 10;
var rotationRadians:Number;
var rotationDegrees:Number;
public function Missile(stageInstance:Stage, rotationDegrees:Number):void {
this.stageInstance = stageInstance;
x = 320;
y = 363;
rotation = rotationDegrees;
rotationRadians = rotationDegrees * Math.PI / 180;
}
public function velocity():void {
velocityX = Math.cos(rotationRadians) * speed;
velocityY = Math.sin(rotationRadians) * speed;
x += velocityX;
y += velocityY;
if(x > 640 || x < 0 || y > 480 || y < 0) {
this.parent.removeChild(this);
}
}
}
}
In the Main Class, I've tried adding something like this:
if(squadron.length > 0) {
for(var j:int = squadron.length - 1; j >= 0; j--) {
squadron[j].fly();
if(salvo.length > 0) {
if(missile.hitTestObject(squadron[j])) {
this.parent.removeChild(this);
}
}
}
}
But no luck. I've also tried using a trace statement, and it doesn't even give me an output, which leads me to think it's not even detecting collision at all. Any ideas?
Update: I added a few more details.
this represents the object on which the function is called. So
this.parent.removeChild(this); makes no sense when it is written in the main class.
When you write it in the Missile Class, this is the Missile instance, and this.parent is the stage.
Try replacing it with: stage.removeChild(missile), in the last sample of code you posted, and call removeMissile() just after.
Try to use stage.removeChild instead this.parent.removeChild(this);
Actually you have many problems in your code. First of all, you don't need to work with Stage. You can work with your main container Main. When you add object to the display list, don't do after setChildIndex. In your code It doesn't have any sense. Also you don't need any length conditions. And create light objects by extending Sprite, not MovieClip.
Code for your loop, for missiles:
private function loop(e: Event):void {
//...not full listing
var i:uint, j:uint, salvos:uint = salvo.length, bombers:uint = squadron.length, missile:Missle, bomber:Bomber;
var disposeMissiles:Array = [];
var disposeBombers:Array = [];
//Rendering missiles
for (i = 0; i < salvos; ++i) {
missile = salvo[i];
missile.valocity();
for (j = 0; j < bombers; ++j) {
bomber = squadron[j];
if (!bomber.isHitted() && missile.hitTestObject(bomber)) {
//Dispose both missile and bomber
bomber.setHitted = true;
disposeMissiles.push(missile);
disposeBombers.push(bomber);
}
}
}
//Clear lists and display list
disposeObjects(disposeMissiles, salvo);
disposeObjects(disposeBombers, squadron);
}
private function disposeObjects(objects:Array, from:Array):void {
//Create interface for both missiles and bombers, like IGameActor
var i:uint, len:uint = objects.length, objectToRemove:IGameActor;
for (i; i < len; ++i) {
objectToRemove = objects[i];
//Remove from the display list, in your design Parent is Stage
this.stage.removeChild(DisplayObject(objectToRemove));
//Release memory, links, event listeners
objectToRemove.dispose();
//Try manage also indexes, splice is slow operation
from.splice(from.indexOf(objectToRemove), 1);
}
}
My game starts with a start frame. click a button to the game. if I hit an object I go to game over screen. Everytime I hit the start over button on the game over screen my characters controls get faster. I have set no variables for speed, simply just "mc_guy.x +=3" or .y , etc. If I had to say by how much faster I would want to say that the speed doubles.

Gameover frame:
import flash.events.MouseEvent;
stop();
restartGame.addEventListener(MouseEvent.MOUSE_DOWN, playAgain);
function playAgain(event:MouseEvent):void{
prevFrame();
}
It sounds like when you restart your game
mc_Guy.addEventListener(Event.ENTER_FRAME, update);
is called again, without removing the previously added listener.
So update is now called two times on Event.ENTER_FRAME, and then once more per frame per game reset, causing the guy to move faster.
