Error #1010

[Zahin24886926j9e0]

Im a beginner at action script and some of the buttons work but as soon as it reaches another page/frame, all of the buttons seem to not work.

TypeError: Error #1010: A term is undefined and has no properties.
at Interactive_storyboard_group_project_fla::MainTimeline/frame11()[Interactive_storyboard_group_project_fla.MainTimeline::frame11:3]
at flash.display::MovieClip/gotoAndPlay()
at Interactive_storyboard_group_project_fla::MainTimeline/fl_ClickToGoToAndPlayFromFrame_5()[Interactive_storyboard_group_project_fla.MainTimeline::frame1:182]

This was the highlight:

scene_2_story.prevBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame_18);

Hi.

Either scene_2_story button or the function  fl_ClickToGoToAndPlayFromFrame_18 is not present in frame 11.

Can you verify this?

Regards,

JC

Both of these exist, first hand I've had the issue of prevBTN being undefined, but after adding scene_2_story since it's my layer name and I'm working with advanced layers seems to bring up this issue.

[JoãoCésar]

To use layers in AS3 in recent versions of Animate, make sure all conditions below are true:

- The advanced layers mode is on (Cmd/Ctrl + J > Use Advanced Layers);

- The virtual camera is on the stage;

- The layer you want to target is on the main timeline;

- The layer you want to target is not empty.

[Zahin24886926j9e0]

I'm pretty sure I've done everything right, I've attached a screenshot of my timeline.

The buttons at homepage sends to the storypage but going back doesn't seem to work, this is all in 1 scene.

Thank you for helping out!

copy and paste here your frame 11 code.

are you using any advanced layers benefit?

[Zahin24886926j9e0]

scene_2_story.prevBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame_18);

function fl_ClickToGoToAndPlayFromFrame_18(event:MouseEvent):void
{
	prevBTN.gotoAndPlay("homepage");
}

The scene_2story doesn't have any impact, just seems to move the undefined error from the Compiler tab to the Output tab

[kglad]

the first line of code isn't line 3.  do you have 2 blank lines above it?

or what version of animate are you using and upload your fla somewhere and post a link.

[Zahin24886926j9e0]

Here is the.fla file

Here is the fla file, apologies for the other reply since it doesn't allow me to attach it directly

[kglad]

turn off advanced layers and stop referencing any layers in code.

[Zahin24886926j9e0]

Forgot to add, I'm only using the camera at the moment but no heavy movement, I've heard there are bugs with using advanced layers. Do you advise me to disable it ?

[kglad · Accepted solution]

YES.  unless absolutely essential. disable it and make that your default setting when starting new fla's.

[JoãoCésar]

Also your layers end before each script frames. Make sure the instances you need are available.

[JoãoCésar]

I got an error in which the compiler doesn't know what prevBTN is. So I added the corresponding layer name like this:

stop();

scene_2_story.prevBTN.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndPlayFromFrame_18);

function fl_ClickToGoToAndPlayFromFrame_18(event:MouseEvent):void
{
	scene_2_story.prevBTN.gotoAndPlay("homepage");
}

@JoãoCésar 

the solution is easy enough. disable advanced layers and remove references to layers in the code, or use advanced layers and use object layers in all the code.

but that doesn't explain why, with advanced layers enabled, the error is on line 3 in the op's posted code when the error on line 7.

i don't think we can determine much from the fla because the op change somethings after posting the error message.

[Zahin24886926j9e0]

I only removed the scene_2_story part on both instances of prevBTN in the code, adding it makes no difference like I mentioned, sorry for any inconvenience.

I'll take the path of disabling the advanced layer since I'm not very good at the concept of coding.

[kglad]

what about the code in frame 1?  there's no reference to a layer there and in frame 11, one reference contains a layer and another doesn't.  i think you're confused over something simple.

again,

either use advanced layers and use those layer names in all object references or

disable advanced layers and use no layer names in object references.

to make this simpler.  which do you want?  advanced layers or not?

[Zahin24886926j9e0]

I've decided to have it without Advanced layers and it's now working fine.

I've tried referencing the layer which gave me that output text in the post's error highlight, which is smth I assumed I did wrong, a guide or pointer would be very helpful in case I need to use advanced layers in the future.

Thank you very much!

[kglad]

if you needed to use advanced layer, you would use the layer names.  (though that looks optional in the first frame for some reason.)

[Zahin24886926j9e0]

Which is another reason that got me super confused and the layer names not working, I'll do some more research after and see what I did wrong, thanks again

[kglad]

that frame 1 exception, i do not understand.
