DebugDraw3D has also supported C# for quite some time, but this support was implemented based on GodotObject.Call, which made DD3D even slower than GDScript when used with C#. Now C# uses the same native API as C++, which makes C# several times faster than GDScript. For example, an array of 7,500 boxes is now sent for rendering in 1 ms instead of 4.2 ms. Roughly 4 times faster on my PC, and 15-28 times faster than the old C# bindings!

The API should have remained unchanged, unless I missed something, except that DebugDraw2D.SetText now requires value to be explicitly converted to a string.

So now, instead of:

DebugDraw2D.SetText("FPS", Engine.GetFramesPerSecond());

You need to write:

DebugDraw2D.SetText("FPS", Engine.GetFramesPerSecond().ToString());

Also, both binding files for C# and C++ now contain the original doxygen documentation, but without images 😅.

Other changes

Core

• Updated godot-cpp to 4.4.1
• Added a dedicated extension_api_double.json for godot-cpp 4.4.1

New

• Added draw_capsule and draw_capsule_ab. #92
• • 
• Added a check for the distance between points a and b in *_ab methods to avoid console spam.
• Added drawing of elements if a path of size 1 was passed to *_path.
• • Now the "path" will be displayed even if only one element is passed. But only in the form of a square or sphere.

Optimizations

• Slightly optimized draw_lines_c and draw_grid_xf.
• Increased the performance of draw_points_c by ~30+%.
• • In some places, raw memory is now used instead of initialized C++ arrays.
• Reduced the number of initializations of new arrays.
• Added manual AABB calculation for instances.
• • Now it should be more accurate and processed faster. ~33ms -> ~24ms (27% faster) with 1M boxes.

C#

• Added converter from doxygen to C# documentation.
• Added automatic removal of old bindings.
• • Added notification about deleting old files.
• Warnings about non-cleared objects are hidden in non-verbose mode. This is because C# clears objects after GDExtensions are unloaded.
• Removed Generate C# bindings from the menu.
• Updated C# demo to support the new SetText.

Various fixes

• Fixed crash when passing a zero-sized array to the draw_arrow_path method. #93
• Fixed text flickering if it updates in the same frame when its time expires.
• Fixed the position of Label3D when the root of the world in which it is located changes its position.
• Fixed the size of the allocated space for the array for vertices and normals of the sphere.
• Fixed interaction between scoped.transform and object position fixing for double builds.
• • Now the correction of the position occurs in one place, instead of each draw_* method.

Demo

• Fixed the appearance of some demo scene elements when rotating the root node.
• Changed the default brightness.
• Replaced the pixel font.

Docs

• Added NativeAPI.md.
• Updated animations in the docs.
• • Used the latest version of ffmpeg. Removed some artifacts.
• Added previews for set_transform.
• • 

Misc

• Redesigned GeometryGenerator to support more accurate alignment of volumetric segments.
• • Also added the ability to locally enable or disable bevels on volumetric meshes.
