Confused With A Class

Question

I was helped by some people for this code and I'm a little lost. This code creates two zigzag lines that fall in a loop. I want to use bitmap data hittest with these lines, just to hit a simple object at the bottom of the screen, but I do not know how. I found the example of Mike Chambers but I do not know what to change to make it work for me. How can I apply it to my code?

import flash.display.Graphics;
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.TimerEvent;
import flash.utils.Timer;
var objectSpawner: Timer;
var fallers: Array;
function initGame(): void {
  fallers = [];
  objectSpawner = new Timer(1000);
  objectSpawner.addEventListener(TimerEvent.TIMER, createEnemy);
  objectSpawner.start();
  addEventListener(Event.ENTER_FRAME, dropEnemies);
function createEnemy(e: TimerEvent): void {
   var enemy: Faller = new Faller();
  enemy.y = -stage.stageHeight;
  enemy.x = Math.random() * 380;
   MovieClip(enemy).cacheAsBitmap = true;
  addChild(enemy);
  fallers.push(enemy);
  drawConnectors();
function dropEnemies(e: Event): void {
  trace(fallers.length);
   for each(var mc: Faller in fallers) {
  mc.y += 10;
   if (mc.y > stage.stageHeight * 2) fallers.splice(fallers.indexOf(removeChild(mc)), 1);
  drawConnectors();
function drawConnectors(): void {
   if (fallers.length == 0) return;
   var g: Graphics = this.graphics;
  g.clear();
  g.lineStyle(10,0xFFFFFF);
   var mc: Faller = fallers[0];
  g.moveTo(mc.x, mc.y);
   for each(mc in fallers) g.lineTo(mc.x, mc.y);
init()
function init():void
   var fallingThingsLeft:FallingThings = new FallingThings(stage.stageWidth / 2, stage.stageHeight);
   var fallingThingsRight:FallingThings = new FallingThings(stage.stageWidth / 2, stage.stageHeight);
  addChild(fallingThingsLeft);
  addChild(fallingThingsRight);
  fallingThingsRight.x = stage.stageWidth / 2;

Answer 1

I don't think you're going to be able to do this right now because your graphics object is in the same object that is the parent of everything else. Create a separate MovieClip/Sprite that contains all your enemies and preferably apply a Class to that that can handle the responsibility of managing the enemies, including drawing the lines. Now you just have to get the BitmapData from that MC/Sprite and hitTest against the BitmapDatas of your two FallingThings. But since you don't keep a reference to your FallingThings objects, you'll need to start keeping a reference to them before you can do any hit testing. I don't see any reference in your code to Touch1, so I have no idea where that "falls" in this scenario.
