This pull request integrates Terasology's PerformanceMonitor with the Tracy Profiler. This allows for better visualising performance traces and should help with diagnosing performance bottlenecks.

How to test

Outstanding before merging

  • Decide on a permanent home for the Tracy bindings library (should it stay under my namespace or be moved into the MovingBlocks organisation?)
  • Decide how to distribute the Tracy bindings library

https://github.com/BenjaminAmos/TracyJavaBindings should be public now. I was staging the library in a private repository and forgot to make it public before creating this pull request.

So, I just tested this out and noticed the following:
When hitting F4 in-game, the game crashed with an UnsatisfiedLinkError: Can't load library: /path/to/Terasology/natives/linux/tracy-jni.dll

What I did:

  1. groovyw lib get TracyJavaBindings
  2. in libs/TracyJavaBindings: chmod +x gradlew && git submodule update --init && ./gradlew jar
  3. Start Terasology and start a new game
  4. Press F4

Logs:

The library loading errors should be fixed by MovingBlocks/TracyJavaBindings@fa7be51.
