Debug drawing utility for Godot

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.

Based on my previous addon, which was developed only for C# https://github.com/DmitriySalnikov/godot_debug_draw_cs, and which was inspired by Zylann's GDScript addon https://github.com/Zylann/godot_debug_draw

Download

To download, use the Godot Asset Library or download the archive by clicking the button at the top of the main repository page: Code -> Download ZIP, then unzip it to your project folder. Or use one of the stable versions from the GitHub Releases page (just download one of the "Source Codes" in assets).

Usage

1. Copy addons/debug_draw_3d to your addons folder, create it if the folder doesn't exist
2. Restart the editor

   

   API

   A list of all functions is available in the documentation inside the editor.

   Besides DebugDraw, you can also use Dbg3.

       DebugDraw.draw_box_xf(Transform3D(), Color.GREEN)
       Dbg3.draw_box_xf(Transform3D(), Color.GREEN)
   

   But unfortunately at the moment GDExtension does not support adding documentation.

   Known issues and limitations

   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 C# binding is not ready yet.
