Node not found " " (relative to "/root/Main") Your First 2D Game

Godot Version

4.6.stable

Question

Hi, I've followed the Your First 2D Game from Godot Docs, everything was working fine until I started connecting signals which I believe I copied to a T. When I hit the start button in game, it quits and I get these errors:

Attempt to call function ‘update_score’ in base ‘null instance’ on a null instance.

_on_score_timer_timeout(): Node not found: “hud” (relative to “/root/Main”).

I downloaded the finished project to compare and everything seems exactlty the same and obviously the finished one works no dramas.

Any help is appreciated, thank you.

That is strange, it looks like it should work. Though in the tutorial the node is called “HUD” instead of “hud”

It might be a cache issue. Please close godot, open up your project folder, and delete the .godot FOLDER. This is a folder that contains a lot of cached data, and godot will re-generate it once you open the project again.
PLEASE make sure you delete ONLY the folder called .godot and nothing else. That folder is safe to delete. If you don’t see the folder, go to your windows explorer settings, and enable the visibility of hidden folders and files.

Yeah, I could try making everything HUD but surely if everything is hud it should work regardless?

[baharatbish]

No difference I’m afraid, thanks though!

I did make some kind of progress by changing _*on_*score_timer_timeout to _on_Score_Timer_Timeout, but when I do this to on start timer timeout below it just doesn’t spawn enemies. And I still have the persistent issue which is that the timer just disappears when I press start in game, which I forgot to mention.

Check the remote scene tree. (Start the game, even if it crashes. Then click “Remote” above your scene tree.)

Are all nodes in their expected positions? Anything missing (or doubled)?

[baharatbish]

Everything but hud is there, weird! What do next? I am very new to godot sorry, just trying to make my way through the docs to get started.

[hyvernox]

Check if you accidentally added the HUD to the “mobs” group. In that case it would get deleted when the game starts.

[Stenium_112]

Via the remote scene tree you can copie the node path once you clicked on hud.

There should be copie path or things like that.

And replace the signal path of hud with what you copied.

Okay so, this was true, I had added HUD to mobs group somehow. After unchecking it didn’t affect anything, but then I reconnected the "‘on score timer timeout’ signal afterwards and now it’s running as intended! Thank you very much.
