In Godot 3, I made a small, 3rd-person car game to practice using Godot, and I used a Spring Arm with a script I wrote with the help of a tutorial. However, that tutorial told me to use the translation keyword to assign the Spring Arm's translation to the car, and then specifically to set the y translation.

When I copied the script over to Godot 4, I had a few errors which I expected and removed, however I can't figure out how to fix this one. It treats "translation" as if it's a variable name, however Godot 3 treats it as the car's position, which I want.
I would just leave the Spring Arm parented to the car, but it also rotates with the car and I don't want that.
