[Issue/Bug]: Parse error when launching a game with DiscordRPC, even with checks to disable running DiscordRPC in place.

[sourcelocation]

What happened?

When launching the game on mobile, it crashes while parsing the file where I'm using DiscordRPC, even with checks to avoid running the code on mobile.

Version

1.3.1

Godot Version

4.2.1

Exact steps to reproduce this error

Use DiscordRPC on mobile, but don't run it. You will get this error

GDScript

func set_up():
	print(OS.get_name()) # prints: Android
	if is_mobile: return
	DiscordRPC.app_id = 1234945200032317602 # Parse Error

Godot output

No suitable library found for GDExtension: res://addons/discord-rpc-gd/bin/discord-rpc-gd.gdextension. Possible feature flags for your platform: mobile, android, etc2, astc, arm64, template, debug, template_debug

Additional information

No response

Checks

• I tried reinstalling the addon or tried to fix it myself with other methods.
• I tried restarting Discord and Godot completely.
• I did read the documentation https://vaporvee.com/docs/discord-rpc-godot/

there is a function to unregister that in GDExtentionManager i think. will send you a solution when I'm at home. on web it doesnt crash never tested it on mobile tbh

Thank you, will be waiting

[vaporvee]

Sorry for not responding will have time next week

No problem, I'm still developing my game to this day.

Try

if GDExtensionManager.is_extension_loaded("res://addons/discord-rpc-gd/bin/discord-rpc-gd.gdextension"):

before loading any part of the plugin also exclude the plugin in the export settings like the following and tell me if it helped.

I don't have the project anymore where i accomplished this but i remember GDExtensionManager is the way.

This did not seem to work for me, and I still get the Identifier "DiscordRPC" not declared in the current scope error, despite writing code to avoid running lines with DiscordRPC. I know that it was mentioned in #67 that Discord rich presence is not possible, but I would love to know if there is some sort of workaround to avoid having the game crashing on mobile.

[Yolwoocle]

Ideally, since try/catch patterns are not a thing in Godot, this plugin should avoid causing crashes on unsupported platforms.

[vaporvee]

the issue is this is just how godot runs gdextensions i can't change that. Is the autoload maybe still running? you should only add the node conataining a script with discord rpc when the plugin is loaded so you cant do

if GDExtensionManager.is_extension_loaded("res://addons/discord-rpc-gd/bin/discord-rpc-gd.gdextension"):
    DiscordRPC.app_id= xyz

instead you need to do

if GDExtensionManager.is_extension_loaded("res://addons/discord-rpc-gd/bin/discord-rpc-gd.gdextension"):
    add_child(your_node_with_discord_rpc_xyz)

[vaporvee]

then you maybe make a manager with the node saved and run stuff on it when its not null

[Yolwoocle]

Okay, thank you for your answer. I ended up making a scene for the Discord rich presence, and put something like this in my main autoload, which seems to do the trick.

func is_discord_rpc_supported() -> bool:
	return game_platform == GamePlatform.PC and GDExtensionManager.is_extension_loaded("res://addons/discord-rpc-gd/bin/discord-rpc-gd.gdextension")

func _init_discord_rpc():
	if not is_discord_rpc_supported():
		return
	
	var discord_rich_presence_scene: PackedScene = load("res://scenes/integration/discord_rich_presence.tscn")
	discord_rich_presence = discord_rich_presence_scene.instantiate()
	add_child(discord_rich_presence)
	
	discord_rich_presence.initialize()

I'll add that to the troubleshooting guide if that's okay :)

Sounds good. Feel free to use my bit of code if needed
