How to Save and Load in Godot

Create a script inheriting from resource.
Put any variables you want in the script, but only use built-in types.
Only variables with the export tag will be saved.
You can initialize the variables by overriding the _init() function.
Give your resource script a class name at the top of the script.
In a separate script, declare a variable using the resource class name as the type.
Create the resource using the class name followed by .new().
Save the resource using ResourceSaver.save(_var_name, "user://filename.res")
Load the resource using _var_name = ResourceLoader.load("user://filename.res")
Be sure to set the variables inside the resource before saving, and get their values after loading.

Really helpful video
Also consise and clear, wich is perfect!

[@TYanuziello]

Glad it was helpful!

[@cltran86]

Concise and to the point. More tutorials should strive for this

[@skaruts]

Nice video. You don't need the "_init" function for default values though. You can define the variables with values by default:
*@export foo: int = 10*

[@TYanuziello]

I know, just a habit for initializing more complex structures. Obviously most save files will contain more than just 1 integer.

Can this save custom resources?

[@TYanuziello]

Yes, this is a custom resource that I created in the video.
