godot_debug_draw_3d

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, C++ or C#.

Based on my previous addon, which was developed only for C#, and which was inspired by Zylann's GDScript addon

API

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).

Known issues and limitations

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.

Frustum of Camera3D does not take into account the window size from ProjectSettings.

Usage Analytics

This addon collects anonymous statistics on editor usage time. The data includes the library version, engine version, operating system, system architecture, and locale. No personally identifiable information is gathered.

Libraries without editor support do not collect statistics in any way. Also, previews running in the editor do not collect any usage statistics.

You can disable this in the editor settings at: debug_draw_3d/settings/telemetry_state.
