Issue description

I am new guy with using godot and everything all fine when I was develop in IDE to get resource for my sprite node. I am going to change the sprite frame variable when click button. Here are code:

		if item.get_extension()=='tres':
			var petRes = load('res://pets/'+item)
			var petBtn = Button.new()
			petBtn.text = str(item.get_file())
			petBtn.pressed.connect(self._button_pressed.bind(petBtn.text))
			petPool.add_child(petBtn)
			petList[petBtn.text] = petRes

I have tried load(), preload(), ResourceLoader.load() everything fine when test in editor. but after exported the game can't find resource via dir: res:// I don't know why and how can I do?

Steps to reproduce

const PETPATH = 'res://pets'
# dict to store a button and spriteFrame
var petList = {}
@onready var fileDia = $settingPanel/addNewPet/filedialog

# Called when the node enters the scene tree for the first time.
func _ready():
	
	get_tree().root.set_transparent_background(true)
	pet = get_node("Area2D/pet")
	parent = get_node("Area2D")
	setPanel = get_node("settingPanel")
	petPool = setPanel.get_child(2)

	# create a button for each pet option
	for item in DirAccess.get_files_at(PETPATH):
		if item.get_extension()=='tres':
			var petRes = load('res://pets/'+item)
			var petBtn = Button.new()
			petBtn.text = str(item.get_file())
			petBtn.pressed.connect(self._button_pressed.bind(petBtn.text))
			petPool.add_child(petBtn)
			petList[petBtn.text] = petRes

FileAccess docs:

Note: To access project resources once exported, it is recommended to use ResourceLoader instead of FileAccess, as some files are converted to engine-specific formats and their original source files might not be present in the exported PCK package.

DirAccess docs:

Note: Many resources types are imported (e.g. textures or sound files), and their source asset will not be included in the exported game, as only the imported version is used. Use ResourceLoader to access imported resources.

See also:

• Listing directories in exported project returns only *.import files #25672
• Directory dir_exists fails on exported projects on subpaths & paths with more than 2 slashes in res` #37646
• In exported games, a FileDialog in Resource mode cannot open resources in subfolders #53339
• Cannot open res:// file from directory in exported project through FileDialog #56737

Tanks for guidance. I see, but I store my assets by add in project directly instead of coding if I'm misunderstanding.
Here's snapshot, I add resource .tres in this directory.

What's meaning of using ResourceLoader to access imported resource?

[dalexeev]

The documentation suggests that you should use ResourceLoader.exists() instead of DirAccess.file_exists() to check if a resource exists, but there is no equivalent method for getting the file list (see #59334).

As a workaround, you can check .remap files (see #76823) or register your resources in other place (enum, array, text file, etc.).

Thx for #66014 let me know that .tres files are changed after export, which means when in IDE, they were cat.tres but become car.tres.remap after exporting in my case. As for developing I can modify the path contains .remap. But I have no idea why my resource will change name after export? Doing nothing in script.
