1120: Access of undefined property error AS3

[iabillups]

Hi! I've been working on an interactive character animation for a school project and have been having some issues with it. I'm very new to Animate and was originally working with an HTML5 canvas. I was having issuses with some of my animations and music not playing, so my professor suggested I convert it to an ActrionScript3 file. That fixed those issues, but presented many more as I have to recode all of my animation.

The animation is a basic dress up game where the player can press start, click on an area to reveal a piece of clothing, click on the clothing to put it on the character, and then click a button that restarts the animation. I've been working with simple timeline animation, calling frames and frame labels to jump around, however when using code snippets to re-code my buttons I got an error saying, "1120: Acess of undefined property clothesRVL." My animation was working fine before I added an action to clothesRVL, and I suspect it's not working because I called a frame label and not a frame. I appreciate any help I could get with this as this is my final project and I'd like to get this working by tonight! I'll paste my current AS3 code and original Javascript code below:

JS Code ---

Frame 1:

var _this = this;

_this.stop();

var _this = this;

_this.Button2.on('click', function(){

_this.gotoAndStop(242);

});

var _this = this;

_this.blanketBTN.on('click', function(){

_this.gotoAndStop(251);

});

var _this = this;

_this.shirtBTN.on('click', function(){

_this.gotoAndStop(253);

});

var _this = this;

_this.clothesBTN.on('click', function(){

_this.gotoAndPlay('clothesRVL');

});

var _this = this;

_this.pantsBTN.on('click', function(){

_this.gotoAndStop(263);

});

var _this = this;

_this.drawerBTN.on('click', function(){

_this.gotoAndStop('drawer open');

});

var _this = this;

_this.socksBTN.on('click', function(){

_this.gotoAndStop('Socks On');

});

var _this = this;

_this.curtainBTN.on('click', function(){

_this.gotoAndStop('shoesRVL');

});

var _this = this;

_this.shoesBTN.on('click', function(){

_this.gotoAndPlay('Shoes On');

});

Frame 266:

this.stop();

Frame 361:

//
//var _this = this;
//_this.endBTN.on('click', function(){
//_this.gotoAndStop(1);
//});

AS3 Code:

Frame 1:

Button2.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

function fl_ClickToGoToAndStopAtFrame(event:MouseEvent):void
{
gotoAndStop(242);
}

blanketBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

{
gotoAndStop(251);
}

shirtBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

{
gotoAndStop(253);
}

clothesBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame);

function fl_ClickToGoToAndPlayFromFrame(event:MouseEvent):void
{
gotoAndPlay(clothesRVL);
}

I forgot to add that I looked through other forum posts on this error and tried the suggestion of turing off advanced layers but it didn't work. 😞

what's the line of code triggering the error?

[iabillups]

Hi! Thank you very much for responding. I tried your suggestion and I was still getting the same error. 😞 The error is on line 42, which has the code " gotoAndPlay(clothesRVL);"

[kglad]

is clothesRVL defined?

or is it a frame label that you failed to put in quotes.

[iabillups]

My coding skills are very limited, so I'm not 100% sure how to define clothesRVL. Based on working in the HTML5 document, I thought I could just call the frame label in the code because it already exists on the timeline. Changing line 42 to say "gotoAndPlay("clothesRVL");" instead did fix the error I was getting, but now my animation wont function past the start button switching to the next screen.

I just reformatted the rest of my code for frame 1 and I'm confused why my this is the case. To be more clear, the player is supposed to first be able to click on a blanket on a bed, which shows an animation of it moving back, revealing a shirt. The player can then click on the shirt and repeat the process for other areas in the room. This is probably a deeper issue with my code that requires looking at my timeline, but thank you for the help with that error!!

[kglad]

what???

that's not html5/canvas code. it's as3 code.

[iabillups]

Oh yeah, that's what I changed! I might've explained it wrong, but the whole section of code is now:

function fl_ClickToGoToAndPlayFromFrame(event:MouseEvent):void
{
gotoAndPlay("clothesRVL");
}

Like I said, following your suggestion to add quotes around clothesRVL solved the error, but I'm running into more issues with my code haha. I think I might go back to working in my HTML5 document and just omit the addition of music/SFX in it. Hopefully that makes sense. Thanks!

[kglad]

that's still as3.

is your app html5 or as3?

[iabillups]

The file I was trying to work with was as3! It was originally html5, but my music and SFX weren't working with that file type so I converted it to as3. Then, in the as3 file my timeline animations stopped working, which was part of what prompted that original 1120 error.

[kglad]

ok.

do you see any error messages?

if not, when do you see a problem? when that goto button is clicked?

[iabillups]

Right now I'm noticing a problem right after the start button is clicked. After the button is clicked, it switches to the next screen. However, I should be able to click on a blanket which would play an animation, but the blanket button is unresponsive. I did just notice I'm getting this error in the output window:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

at FinalProjectMilestoneFour_IB_ActionScriptv02_fla::MainTimeline/frame1()[FinalProjectMilestoneFour_IB_ActionScriptv02_fla.MainTimeline::frame1:17]

If it would help, I'll paste my full updated code below with a screenshot of where all of the animation is happening in the timeline.

Code:

Button2.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

function fl_ClickToGoToAndStopAtFrame(event:MouseEvent):void
{
gotoAndStop(242);
}

blanketBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

{
gotoAndStop(251);
}

shirtBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

{
gotoAndStop(253);
}

clothesBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame);

function fl_ClickToGoToAndPlayFromFrame(event:MouseEvent):void
{
gotoAndPlay("clothesRVL");
}

/* ------- */

pantsBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
{
gotoAndStop(263);
}

drawerBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
{
gotoAndStop("drawer open");
}

socksBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
{
gotoAndStop("Socks On");
}

curtainBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
{
gotoAndStop("shoesRVL");
}

shoesBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);
{
gotoAndStop("Shoes On");
}

it would help to post the line of cofe with error.

and that fla has nothing to do with as2, does it?

[JoãoCésar]

Hi.

I'm not sure if this is your case, but in HTML5 Canvas documents the first frame index is 0 and in AS3 documents is 1. So make sure to adjust it accordingly.

If that's not a issue, I think it would be helpful to help debugging the issues you're facing if you can send a link to your FLA here even if you have to use placeholders or even remove assets from your file.

Regards,

JC

This is a good point that @JoãoCésar  has made.

i don't see how an erroneous line number would trigger a 1009 error.
