Finding the number of resources within a specific folder in your Godot project can be surprisingly useful. Whether you're managing assets, debugging, or automating tasks, knowing this count can streamline your workflow. This article will guide you through several methods, ranging from simple scripting to more robust solutions. We'll focus on counting various resource types, highlighting best practices and addressing potential pitfalls.

Why Count Resources?

Knowing the number of resources in a folder offers several advantages:

• Asset Management: Quickly assess the size and scope of your project's assets. This is especially helpful during large projects or when collaborating with others.
• Automation: Integrate resource counting into scripts for automated tasks, such as generating reports or triggering events based on asset quantities.
• Debugging: Verify that the expected number of assets are present, aiding in debugging asset loading or import issues.
• Organization: Maintain a clear overview of your project's structure and asset organization.

Method 1: Using DirAccess (Simplest Approach)

This method uses Godot's built-in DirAccess class. It's straightforward for counting files, but it might require extra logic to filter for specific resource types.

func count_resources(path):
	var dir = DirAccess.open(path)
	if dir == null:
		print("Error: Could not open directory.")
		return 0
	
	var file_count = 0
	dir.list_dir_begin()
	var file = dir.get_next()
	while file != "":
		file_count += 1
		file = dir.get_next()
	dir.list_dir_end()
	return file_count


var resource_count = count_resources("res://assets/textures") # Replace with your path
print("Number of resources: ", resource_count) 

Limitations: This method counts all files and folders within the specified path. You'll need additional checks to filter out non-resource files if necessary.

Method 2: Filtering Resource Types with DirAccess

This improved approach refines the previous method by filtering based on file extensions. It's more accurate for counting specific resource types like textures (.png, .jpg) or scripts (.gd).

func count_resources_by_type(path, extension):
	var dir = DirAccess.open(path)
	if dir == null:
		print("Error: Could not open directory.")
		return 0
	
	var file_count = 0
	dir.list_dir_begin(true) # List files only
	var file = dir.get_next()
	while file != "":
		if file.ends_with("." + extension):
			file_count += 1
		file = dir.get_next()
	dir.list_dir_end()
	return file_count

var texture_count = count_resources_by_type("res://assets/textures", "png")
print("Number of PNG textures: ", texture_count)

Advantages: Provides more precise counting by specifying file extensions. Remember to adapt the extension parameter to match the desired resource types.

Method 3: Recursive Directory Traversal (For Nested Folders)

If your resources are organized across multiple nested folders, a recursive function becomes essential for a complete count.

func count_resources_recursive(path, extension = ""):
	var dir = DirAccess.open(path)
	if dir == null:
		print("Error: Could not open directory: ", path)
		return 0

	var count = 0
	dir.list_dir_begin(true) 
	var file = dir.get_next()
	while file != "":
		var full_path = path + "/" + file
		if dir.current_is_dir():
			count += count_resources_recursive(full_path, extension)
		elif extension == "" or file.ends_with("." + extension):
			count += 1
		file = dir.get_next()
	dir.list_dir_end()
	return count

var total_resource_count = count_resources_recursive("res://assets")
print("Total resources (recursive): ", total_resource_count)

var specific_resource_count = count_resources_recursive("res://assets", "tscn")
print("Total .tscn files (recursive): ", specific_resource_count)

Key Improvement: This recursive function accurately counts resources across all subdirectories within the specified path.

Choosing the Right Method

The best method depends on your specific needs:

• Simple count of all files: Method 1.
• Count of specific resource types in a single folder: Method 2.
• Count of specific resource types across nested folders: Method 3.

Remember to replace "res://assets/textures" or "res://assets" with the actual path to your resource folder. Always handle potential errors (like a non-existent directory) gracefully, as shown in the code examples. These methods provide efficient and flexible ways to manage your Godot project's resources.
