Update all resources after modifying a resource class

Godot’s resources are quite powerful. However, modifying a resource class doesn’t automatically update any corresponding .tres files, unless you happen to edit a scene that uses that resource in some way. This doesn’t impact runtime behavior — the game still runs as expected. But it can impact version control and result in a messier diff where seemingly unrelated files are modified, which increases the chance of merge conflicts.

A simple way to address this is to update all resources by re-saving them after modifying a resource class and check everything in with the same git commit. Godot doesn’t have that functionality built in, but it’s easy to create a script to do this.

@tool
extends EditorScript

## Crawls the entire codebase, loads, and re-saves every resource.
## Run this script with CTRL/CMD+SHIFT+X.


func _run() -> void:
	for filename in _build_file_list("res://", "tres", 20):
		var res: Resource = ResourceLoader.load(filename)
		ResourceSaver.save(res, res.resource_path)
	

static func _build_file_list(
	path: String, 
	suffix: String, 
	recursion_depth: int
) -> Array[String]:
	var dir = DirAccess.open(path)
	if not dir:
		push_error("An error occurred when trying to access path: %s" % [path])
		return []

	var files: Array[String]
	dir.list_dir_begin()
	var file_name = dir.get_next()
	while file_name != "":
		if dir.current_is_dir() and recursion_depth:
			var sub_dir: String = "%s/%s" % [path, file_name]
			files.append_array(_build_file_list(sub_dir, suffix, recursion_depth - 1))
		elif file_name.ends_with(suffix):
			var full_path = "%s/%s" % [path, file_name]
			files.append(full_path)
		file_name = dir.get_next()

	return files

    When not all strings are Strings. Detect bugs in your GDscript more easily with static typing

    One of the benefits of working with Godot Engine is that GDScript allows one to operate high level. GDScript is dynamically typed, so not even variable types have to be specified, but I would strongly recommend using static typing wherever possible. It can help with performance but primarily adds clarity when trying to follow the …
