This is an add-on for debug drawing in 3D and for some 2D overlays, which is written in C++ and can be used with GDScript or C#.
Based on my previous addon, which was developed only for C#, and which was inspired by Zylann's GDScript addon
Your support adds motivation to develop my public projects.

Simple test:
func _process(delta: float) -> void:
var _time = Time.get_ticks_msec() / 1000.0
var box_pos = Vector3(0, sin(_time * 4), 0)
var line_begin = Vector3(-1, sin(_time * 4), 0)
var line_end = Vector3(1, cos(_time * 4), 0)
DebugDraw3D.draw_box(box_pos, Vector3(1, 2, 1), Color(0, 1, 0))
DebugDraw3D.draw_line(line_begin, line_end, Color(1, 1, 0))
DebugDraw2D.set_text("Time", _time)
DebugDraw2D.set_text("Frames drawn", Engine.get_frames_drawn())
DebugDraw2D.set_text("FPS", Engine.get_frames_per_second())
DebugDraw2D.set_text("delta", delta)
This project has a separate documentation page.
Also, a list of all functions is available in the documentation inside the editor (see DebugDraw3D and DebugDraw2D).
Enabling occlusion culing can lower fps instead of increasing it. At the moment I do not know how to speed up the calculation of the visibility of objects.
The text in the keys and values of a text group cannot contain multi-line strings.
The entire text overlay can only be placed in one corner, unlike DataGraphs.
Frustum of Camera3D does not take into account the window size from ProjectSettings.
The version for Godot 4.0 requires explicitly specifying the exact data types, otherwise errors may occur.
