Minimal Godot setup to showcase use and integration of friflo EcGui.

friflo EcGui can be integrated in every environment that support ImGui.NET.

Ready-to-run Demos are available for: MonoGame, Godot, SDL3 GPU and Silk.NET.OpenGL.
See: EcGui Demos

• Provide instant access to entities their components, tags and relations at runtime via Explorer and Inspector window.

• Provides a good understanding of how ECS query filters work by adding or removing components or tags in the Explorer.
  The demo allows you to immediately dive deep into ECS without coding.

• EcGui accelerates development speed of your ECS significant.
  It makes the need of a debugger (Watch & Variables window) or logging in big parts obsolete.
  Typical weak points using a debugger or logging:

  • Debugger: Requires to stop the process and finding all required data is time consuming.
  • Logging: Over logging impacts performance, disk space and bandwidth. Logging less data carries the risk of missing important data.
    Logging clutters the code with log statements and may introduce exceptions.

• Integration requires only 3 simple method calls:

  // on startup
  EcGui.AddExplorerStore("Store", store);
  // in render loop
  EcGui.ExplorerWindow();
  EcGui.InspectorWindow();

  Additional queries and systems can be added to the Explorer at any time with:

  EcGui.AddExplorerQuery("myQuery", myQuery);
  EcGui.AddExplorerSystems(root);

• ECS data rendering, editing and interaction with the EcGui is instant.

• The impact on game loop performance and rendering is negligible.
  The entire execution time (ECS data access, layout and rendering) is ~0.1 - 0.5 ms per frame on a modern dev system.
  The execution requires no heap allocation in common cases to prevent impacting performance by GC collections.

ECS 
- DemoECS.cs      Creates an example store with some entities. Show how to customize EcGui.
- DemoTypes.cs    Contains various example types: components, relations, tags, custom types and enums
- TypeDrawers.cs  Custom TypeDrawer's are optional.
                  They enable to render custom types in a single line. E.g. Point, Color, Sprite, ...
