Array not resetting in Game - arrays

Question

Hey guys so i am developing a Game and i have an Array that keeps track of my 5 movie clips that are added to the stage by the array. I have a Player movie clip as well so the Player movie clip is Hittesting with all the 5 diamond movie clips which are added to the stage like so:
private var nPoints:Number = 5;..........
public function addPointsToStage():void
{
for (var i = 0; i < nPoints; i++)
{
trace(aPointsArray.length);
points = new mcGainPoints();
stage.addChild(points);
points.x = startPoint.x + (xSpacing * i);
points.y = startPoint.y - (ySpacing * i);
aPointsArray.push(points);
}
}
Now when the Player comes in contact with all the 5 movie clips everything works fine and the output for the array looks like this:
0
1
2
3
4
Then it continues to the next level.
But say that my Player doesnt hit any of the 5 movie clips or only hits a couple of them, when the next level is started the output looks like this:
5
6
7
8
9
and when the next level is started weird things start happening like points start adding to the highscore by themselves.
I think the problem is that im not destroying the array holding the 5 movie clips correctly this is the code i use to start the next level and destroy the array:
if(player.hitTestObject(mcGoal_1))
{
//Remove all points from array/stage
for (var i:int = 0; i < aPointsArray.length; i++)
{
if (aPointsArray[i].parent)
{
parent.removeChild(aPointsArray[i]);
}
startNextLevel();
}
The mcGoal_1 is the object of the game so if the player hits the goal_1 then destroy all array objects on screen and start next level. This is the startnextlevel function.
private function startNextLevel():void
{
//add points to next stage
addPointsToStage();
}
So can you see why when the next level starts the array isnt reset back to 01234? I think thats why the game has that bug of randomly adding points. Please any help will be appreciated

Answer 1

//Remove all points from array/stage
for (var i:int = 0; i < aPointsArray.length; i++)
if (aPointsArray[i].parent)
parent.removeChild(aPointsArray[i]);
// just one statement, no braces
aPointsArray.length=0; // clear the array itself, not just
// points from display list!
startNextLevel(); // now start level
An incorrect order of correct statements leads to a disaster. Always check your code flow, what executes now and what then, and how many times.

It doesn't look like you're removing anything from the array.
You can use a combination of .indexOf() and .splice() to remove items from an array:
function removeMc(clip:MovieClip):void
{
if(clip.parent) clip.parent.removeChild(clip);
// Also remove from array.
var index:int = aPointsArray.indexOf(clip);
aPointsArray.splice(index, 1);
}
It might also be worth simply emptying the array when you startNextLevel():
private function startNextLevel():void
{
aPointsArray.length = 0;
//add points to next stage
addPointsToStage();
}

Just assign your array to null value. so that array will start from begining whenever you require. i hope the following code code would helps you.
var nPoints:Number = 5;
var points:poin;
var aPointsArray:Array;
var startPoint:Number = 0;
var xSpacing:Number = 20;
var ySpacing:Number = 20;
addPointsToStage();
function addPointsToStage():void
{
aPointsArray = null;
aPointsArray = new Array();
for (var i:int = 0; i < 6; i++)
{
trace(aPointsArray.length);
points = new poin();
addChild(points);
points.x = 100+ (xSpacing * i);
points.y = 200 - (ySpacing * i);
aPointsArray.push(points);
}
}
