Is there way to create enums in GDScript?

Question

I'm asking because code editor highlights world "enum" and I failed to find any info abut this in documentation (both on website and build-in)

Edit: I see that this is possible to use exported value like this but I wonder is there any GDScript only solution.

# Editor will enumerate as 0, 1 and 2
export(int, "Warrior", "Magician", "Thief") var character_class

I suppose this explains everything, thanks :)

Answer 1

Don't know if anyone is still looking for an answer to this, but I'm not sure when it was added or if it's in stable, but doing

enum NAME{
  someEnum,
  otherEnum
}

works as far as I know
then accessing doing

NAME.someEnum

Thanks! It does work. I guess it's in the new build.

enum was added in 2.2-alpha/3.0 (see GDScript basic documentation)

For random googlers, this is the right answer, but in historical context, accepted answer was the right one (the question & answer was asked before 2.1)

---

I copy/paste this code and Godot say "Unexpected token: Identifier: enum" :S
I use Godot 2.1.1 x11 64Bits

---

It worked when compiled from source. I guess it wasn't in the latest stable build.

About the historical context, what is funnier is that I made the enums PR to godot :D.

Anyway, it is actually in 2.2-alpha/3.0.

Answer 2

Currently there are a few ways to do it is:

# Multiple constants
const CORNER_W  = 0
const CORNER_NW = 1
const CORNER_NE = 2
const CORNER_E  = 3
const CORNER_SE = 4
const CORNER_SW = 5

# Dictionary (mutliline, since it avoids the ugly quotation marks) (thanks @sal_vager)
const CORNER = {
    W = 0,
    NW = 1,
    NE = 2,
    E = 3,
    SE = 4,
    SW = 5
}
# Class (thanks @DriNeo)
class Corner:
    const W = 0
    #....
# Preload
const Corner = preload("corner.gd") # Assuming it has the same structure to the class above

There is a feature request on github about it though: https://github.com/godotengine/godot/issues/2966

You could use a constant dictionary for this.

I.e.

const HEROES = {
    "Warrior":0,
    "Magician":1,
    "Thief":2
}

So HEROES["Magician"] would return 1

@sal_vager, Thanks for the suggestion, seems like I forgot that this time :). Anyway, added it to the question.

---

And what do you think about this ? If it's bad, feel free to answer.

class Corners:
 const W  = 0
 const NW = 1
 const NE = 2
 const E  = 3
 const SE = 4
 const SW = 5

---

It looks like the first and second combined, but I'm going to add it too :)... For others, you can comment to the issue itself if you think you have a very bright idea ;)

---

Wow plenty of options here. Thank you, :)
I like subclass solution, it seems elegant.

---

I like the use of the class for this, I had read that static variables were not supported so I didn't want to suggest a class that had to be initialized.

I didn't realize that constants would work for this, thank you, I've learned something today :)
