Update godot_headers/ Files
Run make update_godot_headers_from_binary if the extension_api.json doesn't match the godot version:
...
"header": {
"version_major": 4,
"version_minor": 5,
"version_patch": 1,
"version_status": "stable",
"version_build": "custom_build",
"version_full_name": "Godot Engine v4.5.1.stable.custom_build",
"precision": "single"
},
...
This does 2 things
- GDExtension header file "gdextension_interface.h". This file is the base file required to implement a GDExtension.
- Generate a JSON dump of the Godot API for GDExtension bindings named "extension_api.json" in the current folder.
Generate Go Codegen wrapping the godot_headers files
Run make generate
