Hi,
I keep getting this error: E 0:00:01.353 get_node: (Node not found: "Head/Camera/RayCast" (relative to "/root").)
<C++ Error> Method failed. Returning: nullptr
<C++ Source> scene/main/node.cpp:1466 @ get_node()
<Stack Trace> weapon.gd:7 @ _ready()

Here is my code and node hierarchy:

I have searched many forums and found solutions for similar issues (on GitHub, StackOverflow, etc), yet nothing seems to be working. Am I missing something here?

That error message implies that script is attached to a node whose parent is /root, not Player. But that seems to contradict the screenshot.

Try adding this to that script, and post the output:

func _ready() -> void:
    get_parent().print_tree()

      It looks like that script is attached to a node other than "weapon". Is it also attached to Weapon, the node that's printed first? That would explain the error message, since Weapon's parent is apparently /root.

        DaveTheCoder Ah, I think I might understand what's wrong. I believe it has something to do with how the root of the scene changes when I bring my Player into the Main scene, and so its children also change. The other "Weapon" is just a global autoload of my weapon script. Thanks for the help, I'll post here if I get it working!

          I got it... my raycast wasn't enabled lol... wow
