Accessing a variable on the main timeline from a movieclip (HTML CANVAS)

Question

Hi, I have a variable declared on the main timeline:

var myNum= 0;

and i have a movieclip that, if allowed to play to a certain frame without interaction, it needs to add up to that variable on the main timeline. I tried using the following code:

this.parent.myNum = this.parent.myNum + 1;

but it doesn't work and can't seem to find the variable at all. What is the correct syntax for this? Can someone please help? Thanks!

Hi.

The most common approach is to make the variable a property of the timeline you want to target.

So instead of writing:

var myNum = 0;

You would write:

this.myNum = 0;

And then a child of the target timeline could read or write that property like this:

this.parent.myNum++;

Or you can use the exportRoot global variable that is automatically created in the publishing process from anywhere to reference the main timeline. Like this:

exportRoot.myNum++;

I hope it helps.

Regards,

JC

I managed to use a dispatchEvent instead of trying to call a variable from the main timeline inside the movieclip, it works perfectly!
