[SOLVED] Error while publishing + dwl/upl of project scene

Help & Support
1

Hello, I am having major issues with a scene that turns black while:

  1. Playcanvas publishing (DesOn_WegZooTchUpCtrl_SoloScn - PLAYCANVAS) +
  2. dwl/upl of project scene (tmp link: https://amfibios.dk/Deson/WCE/)

What to do?

Looks like an error on the custom pre loader that you are using

I get a null exception error on hideSplash when trying to find the splash wrapper.

Edit: For some reason, hideSplash gets called twice :thinking:
Edit2: As a stupid question, did you include all the scenes into the build? Looks like it can’t load a specific scene?

Nevermind, found the error. Try launching the editor version without the the ?debug=true on the end, you get the same black screen issue.

Your CommScrScript.prototype.gfg_Run function is causing this issue as it doesn’t handle the case of no parameters.

You were right - works with a try/catch around it :slight_smile:
I will have to start and use the console in that way also when debugging

5

Or you could check for the number of params/possible edge case.

6

I understand your apporach - still, apparently there is a difference in how things compile in editor vs exported (will be more aware of this now)

7

There shouldn’t be. The code is only concatenated. What differences are you seeing? I’ve reproduced the error with the Editor.

8

The only difference I’ve found between editor vs build launching a Playcanvas app is when I do something special with asset.getFileUrl().

When launching from the editor a different/relative url will be returned.

Also if you are accessing anything in the pc.app.stats namespace, I think most of the properties won’t be available in a published build (not sure if this has changed now).

Just to make it clear, I can ‘fix’ your published build in the first post just by changing the URL https://playcanv.as/b/fb644cNZ/?foobar=foobar

Yes, I am all into the ‘breaking down uploaded/published’ if ‘params’ wasn’t fulfilled
The try/catch wasn’t necessary at editor debugging (thus a difference somehow >> editor could live without the ‘?foobar=foobar’ string)
// again thanks

The editor version broke for me when I removed all params. eg https://launch.playcanvas.com/889950

The real fix for me is to do the following:

CommScrScript.prototype.gfg_Run = function () {
    //  var current_url = location.href;    //// NB! husk der er fejl på sidste-felt exvis 'mange,15280' bliver ikke vist grundet indeksering!!!!!!!
    // var current_url = "https://amfibios.dk/N3E/RTP3/WeMesk/modtager.php?sk=undefined@mit,8204@jern,9546@hoved,11231@en,11231@helligdag,13413@mange,15280";

    var url = window.location.href;
    var params = url.split('?'); 

    if (params.length > 1) {

        var current_url_eftSpT = params[1]; console.log(current_url_eftSpT);
        // etc
