Running the application

Windows / Linux / macOS

  • Download Desktop release (alternatively, build the solution and copy Content directory to ‹Game›/Content/)
  • Run ‹Game›/Import.exe "Path to original JJ2" (or drag and drop original Jazz Jackrabbit 2 directory on Import.exe)
    • On Linux and macOS, you can run mono Import.exe "Path to original JJ2"
  • Run ‹Game›/Jazz2.exe
    • On Linux and macOS, you can run mono Jazz2.exe

‹Game› is path to Jazz² Resurrection. You can run Import.exe without parameters to show additional options.

Android

  • Download both Desktop and Android releases (alternatively, build the solution and copy Content directory to ‹Game›/Content/)
  • Run ‹Game›/Import.exe "Path to original JJ2" (or drag and drop original Jazz Jackrabbit 2 directory on Import.exe)
  • Copy ‹Game›/Content/ directory to ‹Storage›/jazz2.android/Content/
    • Alternatively, you can use ‹Storage›/Android/Data/jazz2.android/Content/ instead
    • Create empty file .nomedia in ‹Storage›/jazz2.android/ to hide files from Android Gallery
  • Install Jazz2.apk on Android device
  • Run the newly installed application

Requires device with Android 5.0 (or newer) and OpenGL ES 3.0 support. ‹Storage› could be internal (preferred) or external storage. The application tries to autodetect correct paths.

WebAssembly

  • Go to Jazz² Resurrection page to play Shareware Demo online
    • Alternatively, build the solution and copy Content directory from Desktop release to build target directory

Requires Google Chrome 57 (or newer), Firefox 53 (or newer) or other browser supporting WebAssembly and WebGL.

Dependencies

Windows

  • .NET Framework 4.5.2 (or newer)
  • OpenAL Soft (included in release)
    • Copy x86/openal32.dll to ‹Game›/Extensions/OpenALSoft.x86.dll
    • Copy x64/openal32.dll to ‹Game›/Extensions/OpenALSoft.x64.dll
  • libopenmpt (included in release)
    • Copy libopenmpt.dll (x86, and its dependencies) to ‹Game› directory

Linux

  • Mono 5.0 (or newer)
  • OpenAL
    • Run sudo apt install openal1 if it's missing
  • libopenmpt (included in release)
    • Copy libopenmpt.so (x86, and its dependencies) to ‹Game› directory

macOS

  • Mono 5.0 (or newer)
  • OpenAL should be already installed by OS
  • libopenmpt
    • Copy libopenmpt.dylib (x86, and its dependencies) to ‹Game› directory

Android

WebAssembly

  • .NET Framework 4.5.2 (or newer) / Mono 5.0 (or newer)
  • Mono.WebAssembly.Sdk (included as NuGet)
  • WebGL.NET (included)

Building the solution

Windows

  • Open the solution in Microsoft Visual Studio 2019 (or newer) and build it
  • Copy /Packages/AdamsLair.OpenTK.x.y.z/lib/OpenTK.dll.config to /Jazz2/Bin/Debug/OpenTK.dll.config
  • Copy dependencies to /Jazz2/Bin/Debug/ or /Jazz2/Bin/Release/
  • If you build Release configuration, you have to replace Debug with Release in paths above

Linux

  • Install Mono 5.0 (or newer)
  • Run msbuild in directory with the solution file (.sln):
  • Copy /Packages/AdamsLair.OpenTK.x.y.z/lib/OpenTK.dll.config to /Jazz2/Bin/Debug/OpenTK.dll.config
  • Obtain and copy libopenmpt.so to /Jazz2/Bin/Debug/libopenmpt.so to enable music playback
  • Then you can rebuild the solution only with msbuild command
  • Use msbuild /p:Configuration=Release to build Release configuration, you have to replace Debug with Release in paths above

macOS

  • Install Mono 5.0 (or newer)
  • Open the solution in Microsoft Visual Studio for Mac and build it
  • Copy /Packages/AdamsLair.OpenTK.x.y.z/lib/OpenTK.dll.config to /Jazz2/Bin/Debug/OpenTK.dll.config
  • Obtain and copy libopenmpt.dylib to /Jazz2/Bin/Debug/libopenmpt.dylib to enable music playback
  • If you build Release configuration, you have to replace Debug with Release in paths above

.NET Core 3.0 build can be compiled in a similar way (use Jazz2.DotNetCore project). Compile errors about Jazz2.Android project can be ignored, if the Android build is not needed.

Android

  • Install Mobile development in .NET for Microsoft Visual Studio 2019 (or newer)
  • Open the solution and build Jazz2.Android project
  • Dependencies are already included for common configurations

WebAssembly

  • Open the solution and build Jazz2.Wasm project
  • Dependencies are already included for common configurations

Extensions

OpenGL ES 2.0 (Experimental)

Alternative OpenGL ES 2.0 backend can be built separately. It does not contain all features that are available in default OpenGL 2.1 backend, but it should run faster on low-end configurations. Don't use it if you have no reason to do so!

To use it, build Extensions/Es20Backend project. The library will be copied to /Jazz2/Bin/Debug/Extensions/Es20Backend.core.dll automatically. Then copy all files from Content/_ES20 directory to /Jazz2/Bin/Debug/Content and replace them.

Also, you have to remove /Jazz2/Bin/Debug/Extensions/GL21Backend.core.dll file to disable default OpenGL 2.1 backend.
