xyz Can you give an example for this? Because when I have a file enemy.gd...

# enemy.gd
class_name Enemy extends Node2D

enum Foo { red, green, blue }
# [...]

...and then try to use the enum Foo from another script I cannot access it.

# another.gd
print(Foo.red)
print(Enemy.Foo.red)

This would only result in errors. Am I missing something here?

      Toxe Enemy.Foo.red should work. Assuming you're in 4.x

          xyz I am, but it doesn't.

              Toxe Don't forget to save *.gd files.

                  xyz Looks like I never really tried actually running that code because at runtime it does indeed work. But the editor gives an error message and suggestions don't work either. So in a way it does work if you don't mind a lot of red lines and error message in your code. 😉

                    Okay I restarted the editor and now the red error is gone and suggestions do indeed work. But once I add another value to the enum and try to print that the error comes back.

                    You should submit a bug report on the github tracker.

                      I haven't encountered any funky behaviors so far. It works as expected. Anyway, bugs aside, the point is - enums are global by design.

                        xyz If they are global shouldn't print(Foo.red) then work?

                            They are accessible globally but name-wise they are guarded by class namespaces. In other words, you need to use the class name when accessing, but you can do it from anywhere, hence the access is global. In your example Enemy.Foo is a global enum.

                            Btw this is analogous with access to static class methods and properties. If you declare something static it becomes globally accessible via class namespace. In 3.x you can have static methods but no static properties. They neatly added this in v 4 so now we can have both, making the old autoload hack pretty much obsolete.

                              I know this is an old topic but I made a benchmarker that can show you how much faster or slower using various types of variable references are: https://github.com/elvisish/ElvisishBenchmarker

                              I usually keep enums in the same script for the reason that frequently (every frame) referencing singletons is much slower than a local script reference, but it might not be a big deal if you're only referencing them ocassionally.

                                elvisish What do you mean by "referencing singletons"?
