Debug drawing utility

This is a debug drawing script, which you can setup as an autoload singleton. Written in C#, so only Godot Mono supported.

Inspired by Zilann's addon for the GDScript https://github.com/Zylann/godot_debug_draw

Usage

1. Copy addons/debug_draw_cs to your addon folder, create it if the folder doesn't exist.
2. Rebuild project.
3. Add addons/debug_draw_cs/DebugDraw.cs to your project as autoload singleton.
4. (Optionally) Enable the Debug Draw For Editor plugin to enable debug drawing support inside the editor.

Example (information about all public static functions and properties is present inside the script):

public override void _Process(float delta)
{
    var time = OS.GetTicksMsec() / 1000f;
    var box_pos = new Vector3(0, Mathf.Sin(time * 4f), 0);
    var line_begin = new Vector3(-1, Mathf.Sin(time * 4f), 0);
    var line_end = new Vector3(1, Mathf.Cos(time * 4f), 0);

    DebugDraw.DrawBox(box_pos, new Vector3(1, 2, 1), new Color(0, 1, 0), 0, false);
    DebugDraw.DrawLine3D(line_begin, line_end, new Color(1, 1, 0));
    DebugDraw.SetText("Time", time);
    DebugDraw.SetText("Frames drawn", Engine.GetFramesDrawn());
    DebugDraw.SetText("FPS", Engine.GetFramesPerSecond());
    DebugDraw.SetText("delta", delta);
}

If you see ERROR: _gl_debug_print: GL ERROR: Source: OpenGL Type: Error ID: 1281 Severity: High Message: GL_INVALID_VALUE error generated. Invalid offset and/or size., try increasing the value of rendering/limits/buffers/immediate_buffer_size_kb.
