Get current scene name and if it's main, prevent trigger?

Using JavaScript with Hype
1

Hello again. I’m trying out the key bindings that I posted about yesterday and found a solution by using the keybindings on a scene that only loads the first time the page loads. For some reason the keybindings where doubling the value and adding 1 after each click.
If it started at 1 click the next click would be used 3 times, then 7 times etc… this made the page load really slow and after a while of using it I got javascript crash.

Anyway, I’m trying to get the currentSceneName id and if the id = main it should prevent the click from happening.

Any idea on how to turn this code to what I am looking for?

$(document).on('keydown', function (e){ 
	console.log(e.keyCode);
    if (e.keyCode == 40) { //down arrow
    hypeDocument.showSceneNamed('main');
    }
});

the active scene will be a div with attr ‘aria-hidden=“false”’

do a forumsearch for more info on this …
(though this behaviour may be broken on further releases of hype)

The problem is that it will still trigger the scenes even if you’re on it.
Look at this and you will see what I mean, this is why I need it to be disabled if you are on the main scene, in this case scene “1”.

create a new function and load “onLoadScene”.
then let the action-line empty.

 document.onkeydown = checkKey;

 function checkKey(e) {

 e = e || window.event;

if (e.keyCode == '39') {
// right arrow
//no action
 }
  else if (e.keyCode == '37') {
 // left arrow
    //no action
 }
 }

I’m not at my Mac at the mo. But another approach is to have a global variable the is a BOOL.

in the scene loaded function

I.e. window.mainLoad = true;

Use this in an if clause .

If (!window.mainLoad) {

// do stuff

}

You can then reset it from any other function

window.mainLoad = false;

Example. ( And I know I may be missing what you are trying to do)

Thank you @MarkHunte & @strmiska for taking your time! I did what @strmiska told me to do and it worked. It might not be the best thing to do since you have a javascript on all the scenes but it works as intended. Thanks!

No worries. I’ll post this updated one since I just wrote it any way…
