The files in this folder are all the files you need to upload to your web server. The following will help explain what kinds of files these are. Development Build ================= Packaging "Dewelopment" builds: * Only uncompressed files are built * Jump down to "Local Testing" to test your project Shipping Build ============== Packaging "Shipping" builds: * Can be built with or without uncompressed files * Jump down to "Local Testing" to test your project To package "Shipping" build with "compression" enabled, set the following option in UE4Editor: Project Settings -> Platforms -> HTML5 -> Packaging -> Compress files during shipping packaging Non-Compressed Files ==================== Use this settings (available on Development or Shipping builds) for the best results on being able to server your project from most web host providers. Files Required for Non-Compressed Files Deployment -------------------------------------------------- <project>.js - main project Javascript code <project>.wasm - main game code <project>.data - game content <project>.data.js - game content Javascript driver <project>.html - landing page <project>.symbols - symbols (optional: used with debugging) Utility.js - utility Javascript code .htaccess - "distributed configuration file" Compressed Files (Advanced option) ================ Use this setting (only available on Shipping builds) if you need to help make your project downloads smaller. * NOTE: We recommend you smash your texture sizes for the best results -- this may be enough to NOT require using the compression option. + For more information on how to do this, see: > https://docs.unrealengine.com/latest/INT/Platforms/Mobile/Textures/ > For HTML5, try setting Max LOD Size to 256 and go up from there to ensure quality and download size are acceptable. If you are an advanced web server administrator: * Using compression helps improve download times. * Using pre-compressed files may help your web server from compressing the files dynamically everytime the time your project is loaded on to a browser. * NOTE: Being able to serve pre-compressed files will require configuring your web server to properly serve the UE4 compressed file extention type. + These settings are placed in the .htaccess file > This file will work on most Apache web servers (that have the AllowOveride option set to (e.g.) All). + AGAIN, if you are reading this section, we assume you have a deep understanding of web server technology. > This is not for beginners. Files Required for Compressed Files Deployment - in addition to the Non-Compressed Files (listed above) ---------------------------------------------- <project>.jsgz - compressed main project Javascript code <project>.wasmgz - compressed main game code <project>.datagz - compressed game content <project>.data.jsgz - compressed game content Javascript driver <project>.symbolsgz - compressed symbols (optional: used with debugging) Utility.jsgz - compressed utility Javascript code Files not needed for Deployment - these are normally used during developement =============================== HTML5LaunchHelper.exe - see Local Testing below RunMacHTML5LaunchHelper.command - see Local Testing below Readme.txt - this Readme file Local Testing ============= UE4's test web server --------------------- Run HTML5Launcher.exe (on windows) or RunMacHTML5LaunchHelper.command (on Mac) to start a web sever which is configured to serve compressed files on localhost. * This is NOT a production quality server. * Add -ServerPort=XXXX to the command line if necessary to change the serving port. > Default port is 8000. Python web server ----------------- You may use python's built in web server, e.g.: * (make sure you run the following command from the same path this Readme and <project>.html files are located) python -m SimpleHTTPServer 8000 Apache web server ----------------- OSX and Linux normally have Apache installed. * You can use that for testing which has the closest behavior to most web host providers.
