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 launch stays at "Launching engine"

Hey, i have a project i want to launch as Html5. After the launch on Firefox /Chrome it will successfully download and compile the WebAssembly, but it loops at Launching engine. I allready launched different versions of my project as Html5 but now it stucks at this step of the launch. Is there a way to check why it stucks at this point?

Product Version: UE 4.16

I can't seem to get my project to open when hosted on Amazon S3, any chance you could share what you did after the packaging process to get it running? The .html works fine locally, but I can't seem to figure out why it won't load correctly when hosted.

Try doing a development build, and then checking the console log window on the web page, as well as the console log window in the browser's developer tools. Also if the page is hanging, there might be a slow script dialog that shows up after waiting for a while. Clicking on Stop in that dialog will show a call stack in the browser's log window that shows where execution was halted, and can give clues as to what is going wrong.

Try also deploying one of the stock template projects, e.g. third person example to html5 to make sure that the export path itself works, and debug whether the issue is something related to your project, or exporting in general.

I just rebuilded my solution and updated my Unreal Engine 4.16 and it worked again but thanks for the advice.
