This example project shows how to write native extensions using C++, C# and Zig.

• C++
  • Stable
• Zig
  • Experimental support
  • The current state of the Zig toolchain is not stable, and may be updated at any time.
  • Used an experimental C API for Defold
• C#
  • Experimental support
  • Based on DotNet 9 with AOT compilation
  • Generated from an experimental C API for Defold

Testing locally

The project is also designed to test performance of the different languages.

To build with certain setup, you can use a command line such as:

LOOPCOUNT=1000000 VARIANT=debug SERVER=http://localhost:9000 ./scripts/build_feature.sh arm64-android cpp

• The LOOPCOUNT is used to control how many loops the performance tests should run.
• The cpp controls which language to add. Lua is always part of the tests.
  • Possible values are cpp, csharp, zig and all
