error #2007

[thunderxlight11111]

hi , how are you all? i hope you fine...

iam trying to make a game but when the object hit object to delete  another object i get these errors

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

at flash.display::DisplayObject/_hitTest()

at flash.display::DisplayObject/hitTestObject()

at MAIN/onEnterFrame()

and here is the class

(iam sure the problem from this class because i closed all the classes except 1 )

package  {

import flash.display.MovieClip;
import flash.events.Event;


public class MAIN extends MovieClip {
 
 
 
  public function MAIN() {
addEventListener(Event.ADDED_TO_STAGE,onAddedToStage)  
}


public function onAddedToStage(event:Event):void
  {
addEventListener(Event.ENTER_FRAME,onEnterFrame )
 
 
}

  public function onEnterFrame (event:Event)
  {
  
    if (hero.hitTestObject(bat1) && (bat1) && (bat1.stage))
    {
     healthbar1.width -=1
     trace("HHH")
    }
    if (healthbar1.width >=  80 && healthbar1.width <=  100 ){
     zelda1.gotoAndPlay(1)
    }
    if (healthbar1.width >=  60 && healthbar1.width <=  80){
     zelda1.gotoAndPlay(2)
    }
    if (healthbar1.width >=  40 && healthbar1.width <=  60){
     zelda1.gotoAndPlay(3)
    }
    if (healthbar1.width >=  20 && healthbar1.width <=  40){
     zelda1.gotoAndPlay(4)
    }
    if (healthbar1.width >=  0 && healthbar1.width <=  20){
     zelda1.gotoAndPlay(5)
    }
    if (hero.hitTestObject(portal2)){
     var map2:MAP2 = new MAP2
     addChild(map2)
     if(map1.stage){
     removeChild(map1)
     }
     }
     if (hero.hitTestObject(portal3) && (portal3) && (portal3.stage) && (bat1)){

      var map4:BACKGROUND = new BACKGROUND();

      if(bat1){

     removeChild(bat1)

     bat1.removeEventListener(Event.ENTER_FRAME, onEnterFrame);  // this doesn't need to be done unless you added a listener outside the Bat1 classs

     bat1 = null;

   removeChild(portal3)
   portal3 = null
  
   }
     }
    
  }


}


}

i talked about this problem before in this discuss

i tried alot to check with if statement the bat1 object but this error still.

thank you

[kglad]

you're not following directions.  use the code i suggested.

using

if(hero.hitTestObject(bat1)&&bat1)

is NOT the same as

if(bat1){

if(hero.hitTestObject(bat1))

[thunderxlight11111]

i did this

if(bat1){

if(hero.hitTestObject(portal2)){

      var map4:BACKGROUND = new BACKGROUND();

     removeChild(bat1)

     bat1.removeEventListener(Event.ENTER_FRAME, onEnterFrame);  // this doesn't need to be done unless you added a listener outside the Bat1 classs

     bat1 = null;

removeChild(portal3)

portal3 = null

but you know , after this code this if statement doesn,t work

if(hero.hitTestObject(portal2)){

i dont know why , does the bat become null before that for another reason

thank you

[thunderxlight11111]

ohh sorry, forget that comment i missed somethig there

var map2:MAP2 = new MAP2

addChild(map2)

thank you for your replay

[thunderxlight11111]

i copied it then i pasted it , but the problem still the same?

thank you again for your replay

[kglad]

then you copied incorrectly.

here's your code properly formatted so you can see the if(bat1) statement do not effect the portal2 hittest:

package {

    import flash.display.MovieClip;

    import flash.events.Event;

    public class MAIN extends MovieClip {

        public function MAIN() {

            addEventListener(Event.ADDED_TO_STAGE,onAddedToStage);

        }

        public function onAddedToStage(event:Event):void {

            addEventListener(Event.ENTER_FRAME,onEnterFrame);

        }

        public function onEnterFrame(event:Event) {

            if (bat1) {

                if (hero.hitTestObject(bat1)) {

                    healthbar1.width-=1;

                    trace("HHH");

                }

                if (healthbar1.width>=80&&healthbar1.width<=100) {

                    zelda1.gotoAndPlay(1);

                }

                if (healthbar1.width>=60&&healthbar1.width<=80) {

                    zelda1.gotoAndPlay(2);

                }

                if (healthbar1.width>=40&&healthbar1.width<=60) {

                    zelda1.gotoAndPlay(3);

                }

                if (healthbar1.width>=20&&healthbar1.width<=40) {

                    zelda1.gotoAndPlay(4);

                }

                if (healthbar1.width>=0&&healthbar1.width<=20) {

                    zelda1.gotoAndPlay(5);

                }

            }

            if (hero.hitTestObject(portal2)) {

                var map2:MAP2=new MAP2  ;

                addChild(map2);

                if (map1.stage) {

                    removeChild(map1);

                }

            }

            if (hero.hitTestObject(portal3)) {

                var map4:BACKGROUND=new BACKGROUND  ;

                removeChild(bat1);

                bat1.removeEventListener(Event.ENTER_FRAME,onEnterFrame);// this doesn't need to be done unless you added a listener outside the Bat1 classs

                bat1=null;

            }

        }

    }

}

i copied it , but the problem still

sorry mr.kglad

here is the link of the project 

http://www.2shared.com/file/fIo-BLEw/project__4__.html

thankyou for your replay

[thunderxlight11111]

ohh , sorry forget that

the problem comes after going to the portal 3

[kglad · Accepted solution]

if this thread's problem is resolved, mark helpful/correct responses.

[thunderxlight11111]

no the problem still ?!

i sent the link to you

here

http://www.2shared.com/file/fIo-BLEw/project__4__.html

maybe if you take closer look you will know the reason because you are very good in flash , but with me i did all my best but i couldn,t

thank you again for your replay

[thunderxlight11111]

ok , i will try to do that, i mean to fix it alone

thx mr.glad for your help

[kglad]

you're welcome.

p.s.  someone else might download and correct your file but i generally don't download and correct files unless i'm hired.  if you have a question or problem with code, post it in the adobe forums and you'll probably get free help.

[thunderxlight11111]

ohh , ok thx

but i realy have project in my college i should finish it  before 3 months

sorry mr.kglad iam not sure if i get this sentence " download and correct files unless i'm hired"

i realy need that person ,help me and explain my errors , so can you help me and i can pay for that if you dont mind?

if you have problem you can just ignore this message

sorry again if i said something wrong

[kglad]

ok.

i actually do download and correct files without being hired but only if people offer to pay for my time (like you did).  my feeling is, if it's not worth anything to the person with the problem, it's not worth my time.

anyway, i downloaded and checked your file.  use:

          if (hero.hitTestObject(portal3)) {

                var map4:BACKGROUND = new BACKGROUND();

                if(bat1){

                    removeChild(bat1);

                    bat1.removeEventListener(Event.ENTER_FRAME, onEnterFrame);// this doesn't need to be done unless you added a listener outside the Bat1 classs

                    bat1=null;

                }

            }

[thunderxlight11111]

thank you alot mr.kglad.

[kglad]

you're welcome.
