ActionScript 3.0 - When all objects are drop, move to next scene.

Report · Dec 24, 2015

I want to make drag and drop at certain coordinate.

I have two moving blocks, where player can drag any block at first time onto holder 1. Then, drag another block at second time onto holder 2.

When the block did not hits either holder 1 or holder 2, it will terminate and that block back to the initial coordinate.

When both hit both coordinate of holder, then move to next scene.

import flash.events.Event;

stop();//stop the scene

var startingPt:Point = new Point();//declaration variable

var movingBlock:Sprite;

var placed:int = 0;//initialize

var blok1:Boolean=false;

var blok2:Boolean=false;

var endpoint:Boolean=false;

block3.addEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);//function

block2.addEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

function startBlockMove(evt:MouseEvent):void {//the object move

movingBlock = Sprite(evt.currentTarget);

startingPt.x = movingBlock.x;

startingPt.y = movingBlock.y;

stage.addEventListener(MouseEvent.MOUSE_MOVE, moveBlock);

}

function moveBlock(e:MouseEvent):void {//object move based on mouse coordinate

movingBlock.x = stage.mouseX;

movingBlock.y = stage.mouseY;

}

stage.addEventListener(MouseEvent.MOUSE_UP, stopMotion);//stop move

function stopMotion(evt:MouseEvent):void {

stage.removeEventListener(MouseEvent.MOUSE_MOVE, moveBlock);

snapInPlace();

movingBlock = new Sprite();

startingPt = new Point();

}

function snapInPlace():void {//

if(blok1==false || blok2==false){

if (holder.hitTestObject(movingBlock)) {//object1 hits the goal

movingBlock.x = holder.x;

movingBlock.y = holder.y ;

placed++;

movingBlock.removeEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

blok1=true;

}

else if (holder1.hitTestObject(movingBlock)) {//object2 hits the goal

movingBlock.x = holder1.x;

movingBlock.y = holder1.y;

movingBlock.removeEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

blok2=true;

}

else {

movingBlock.x = startingPt.x;//if not hits the goal, return to original coordinate

movingBlock.y = startingPt.y;

blok1=false;

blok2=false;

}

else if(blok1==true && blok2==true){

setTimeout (function (){ endpoint=true;

trace("You died!");

removeEventListener(Event.REMOVED, snapInPlace);

gotoAndStop(1,"Scene 2");}, 1000);

}

The output gives error,

TypeError: Error #2007: Parameter hitTestObject must be non-null.

Use this code:

var startingPt:Point = new Point();

var placed:int = 0;

block2.buttonMode = block3.buttonMode = true;

block2.addEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

block3.addEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

block2.addEventListener(MouseEvent.MOUSE_UP, stopBlockMove);

block3.addEventListener(MouseEvent.MOUSE_UP, stopBlockMove);

function startBlockMove(evt:MouseEvent):void

{

startingPt.x = evt.target.x;

startingPt.y = evt.target.y;

evt.target.startDrag();

}

function stopBlockMove(evt:MouseEvent):void

{

evt.target.stopDrag();

if(evt.target == block2 && evt.target.hitTestObject(holder1))

{

evt.target.x = holder1.x

evt.target.y = holder1.y

evt.target.removeEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

placed +=1;

}

else if(evt.target == block3 && evt.target.hitTestObject(holder2))

{

evt.target.x = holder2.x

evt.target.y = holder2.y

evt.target.removeEventListener(MouseEvent.MOUSE_DOWN, startBlockMove);

placed +=1;

}

else

{

evt.target.x = startingPt.x

evt.target.y = startingPt.y

}

////

if(placed == 2)

{

gotoAndStop(1,"Scene 2");

}
