Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

HTML5 package when opened in Firefox Nightly, does not show anything.

Hello, I am trying to run the HTML5 package of a project on a Firefox Nightly browser. I am using UE 4.11.2 and latest Nightly build. I am unsure of what the issue is as I followed the instructions on Unreal Documentation. To my knowledge, there is no need of setting up/ installing Python or Emscripten SDK for this version of UE 4. Please let me know if I am mistaken.

As a test, I have also tried creating a very basic project with a floor and a cube. Even this did not work. Please help. Is there anything else that needs to be done apart from the documentation provided? Please see the image for reference.alt text

Product Version: UE 4.11

It is difficult to offer specific help based on only a screenshot of a page and a description that "it does not work", so any more information you are able to offer can help.

Some thoughts:

  • try opening the web page console (right-click on the page background, and choose "Inspect Element", and navigate to the Console tab). Are there any error messages there?

  • can you zip up or host the build somewhere for testing?

  • looking at the URL, you seem to have the cookonthefly feature enabled. Can you re-do the build where you disable that?

  • if you try exporting some other template/default content that UE4 offers, do any of those work? Try any of Empty project, StrategyGame, Sun Temple or PlatformerGame, those are known to export well.

Hello juj,

Thank you for your reply. The thing is that the new UE4 documentation describes that I just need UE4.11 and Firefox Nightly to make HTML5 packaging work. I am able to get HTML packed project work on my machine at home. I just followed the steps in the documentation and it started working.

Currently I am trying to make this project work on a machine at office. That is why I don't know where to start from, trying to troubleshoot this issue.

Regarding your suggestions:

  • Please see attached image with console errors.

  • I cannot share the project I am working on. But I have tried packaging a simple level with a floor and a cube. I have also tried packaging using the FirstPersonExample Map. Everything is showing the same output as you can see in the shared image.

  • I am not sure what 'cookonthefly' feature does or where it is located. I will check its documentation and try to make a package as you have said.

  • Have tried using default maps but result is the same.

I will try using a different machine with clean setup of UE4.11 and Firefox Nightly.

for the first image: cook on-the-fly will be fixed in 4.12....

for the second image: the file:// protocol is not supported -- you need to run the game from a webserver

Hey, Thanks for the response.

Regarding your second point, I tried using the HTML5LaunchHelper and typed the **'http://localhost:8000//Project_Name'** but,

  1. the browser gives me this error '404 Not Found'.

  2. The HTML5LaunchHelper shows the following

    Name: -Browser=

    Name: -ServerRoot= ./

    Name: -ServerPort= 8000

    Name: -BrowserCommandLine=

    Name: -UseAllPrefixes= FALSE

    Starting Server at http://localhost:8000/

    Press Any key Quit Server

I apologize for the late reply. I checked the HTML package output today, after a long time, on Firefox Nightly browser. And surprisingly it started working.

Following are the changes that were made to the system from the time I last posted this question:

  1. Updated to UE 4.12.1

  2. Installed Nvidia GTX 1080 with updated drivers.

I am not sure whether this has caused the packaged project to start working but I just double clicked on the HTML file that was packaged in May and opened it up in Firefox Nightly 64 bit.

Thank a lot for your help! Cheers!
