Godot: Can't instantiate class from within itself

[SolarLune]

Operating system or device, Godot version, GPU Model and driver (if graphics related):

Solus 3 64-bit (Linux), Godot 2.1.4 Stable

Issue description:

You can't instantiate a class from within itself. Here's an example:

extends Spatial

class Test:

    func _init():
        print("Hello, Test.")

    func create_new():
        print("Creating a new one...")
        var n = Test.new() # This doesn't work - it won't even compile.

func _ready():
    var t = Test.new()

see this one. #2012
does it work with var n = get_script().new() instead of var n = Test.new()?

Hey, thanks, it does work! But I'm not sure why get_script() returns the enclosing class and not the class defined in the file (i.e. what extends Spatial)...?

This happens because get_script is a method of the Object class, and thus does not know anything about which file defines the script.

this should be documented in gdscript section. it's a special and gdscript specific case, comparing to other languages.

But the "script" is referring to the script file the classes exist in, right?

Yeah, I agree.

get_script doesn't seem to work from a static function since "Parse Error: Can't call non-static function from a static function. I would like to make static creation funcs likeMyClass.from_string( value )`, but I can't find a way to create the object from that static function. Any ideas?

@cgbeutler Support for creating new instances in a static function is being tracked in https://github.com/godotengine/godot/issues/27491.
