Image and Audio Files not Loading on Export

[dragonforge-dev]

@gertkeno I did not want to hijack this thread as it’s not mine and already solved. However I am interested in what you said.

@gertkeno

As of 4.4 ResourceLoader has .list_directory() which returns all resources in a directory, even after export. This will be more consistent than replacing .import and .remap file extensions

ResourceLoader — Godot Engine (stable) documentation in English

Here’s my code:

func get_random_voice_line(index: int) -> AudioStream:
	var audio_path: String = "res://assets/sound/dialogue/"

	var file_path: String = audio_path + avatars[index] + "/character_selection"
	var dir: DirAccess = DirAccess.open(file_path)
	if not dir:
		return
	
	var filenames: Array[String]
	var file_list: PackedStringArray = dir.get_files()
	for file_name: String in file_list:
		if file_name.ends_with(".import"):
			filenames.append(file_name.trim_suffix(".import"))
	
	var sound_file: AudioStream = load(file_path + "/" + filenames.pick_random())
	return sound_file

Changed from this:

Summary

func get_random_voice_line(index: int) -> AudioStream:
	var audio_path: String = "res://assets/sound/dialogue/"

	var file_path: String = audio_path + avatars[index] + "/character_selection"
	var dir: DirAccess = DirAccess.open(file_path)
	if not dir:
		return
	
	var filenames: Array[String]
	var file_list: PackedStringArray = dir.get_files()
	for file_name: String in file_list:
		if file_name.ends_with(".wav"):
			filenames.append(file_name)
	
	var sound_file: AudioStream = load(file_path + "/" + filenames.pick_random())
	return sound_file

But the ResourceLoader doesn’t use DirAccess. So would you suggest using ResourceLoader to traverse the directory and then DirAccess to get the files? Or convert the whole thing to use ResourceLoader?

[gertkeno]

I’d propose these changes to make use .list_directory()

func get_random_voice_line(index: int) -> AudioStream:
	var audio_path: String = "res://assets/sound/dialogue/"

	var file_path: String = audio_path + avatars[index] + "/character_selection"
-	var dir: DirAccess = DirAccess.open(file_path)
-	if not dir:
+	if not DirAccess.dir_exists_absolute(file_path):
		return
	
	var filenames: Array[String]
-	var file_list: PackedStringArray = dir.get_files()
+	var file_list: PackedStringArray = ResourceLoader.list_directory(file_path)
	for file_name: String in file_list:
		if file_name.ends_with(".wav"):
			filenames.append(file_name)
	
	var sound_file: AudioStream = load(file_path + "/" + filenames.pick_random())
	return sound_file

ResourceLoader.list_directory doesn’t use DirAccess, it’s only intended to be used with “res://” paths so traversal should be simple and export-time known as is in your code.

That works and is cleaner. Thank you @gertkeno!

This was my final version.

func get_random_voice_line(index: int, category: String) -> Dictionary[String,AudioStream]:
	var audio_path: String = "res://assets/sound/dialogue/"

	var file_path: String = audio_path + avatars[index] + "/" + category
	var file_list: Array[String] = get_file_list(file_path, ".wav")
	
	var file_name: String = file_list.pick_random()
	var sound_file: AudioStream = load(file_path + "/" + file_name)
	
	#Get the option
	var regex := RegEx.new()
	regex.compile(r"\d")
	var option := regex.search(file_name)
	
	return {option.get_string(): sound_file}


## Returns a list of files located in the passed file_path that have the passed
## extension.
## Wroks even in exported games.
func get_file_list(file_path: String, extension: String) -> Array[String]:
	if not DirAccess.dir_exists_absolute(file_path):
		return []
	
	var filenames: Array[String]
	var file_list: PackedStringArray = ResourceLoader.list_directory(file_path)
	for file_name: String in file_list:
		if file_name.ends_with(extension):
			filenames.append(file_name)
	
	return filenames
