Using Godot 3.4, I have an enum setup as:
enum {STRENGTH, DEXTERITY, CONSTITUTION, INTELLIGENCE, WISDOM, CHARISMA}And I would like to be able to make the string "STRENGTH" return the enum value (0). I would like the below code to print the first item in the array however it currently presents an error that STRENGTH is an invalid get index.
boost = "STRENGTH"print(array[boost])Am I doing something wrong or is there a function to turn a string into something that can be recognised as an enum?

First of all, your enum needs a name. Without the name, the enum is just a fancy way to make a series of constants. For the purposes of this answer, I'll use MyEnum, like this:
enum MyEnum {STRENGTH, DEXTERITY, CONSTITUTION, INTELLIGENCE, WISDOM, CHARISMA}Now, we can refer to the enum and ask it about its elements. In particular, we can figure out what is the value associated with a name like this:
var boost = "DEXTERITY"print("Value of ", boost, ": ", MyEnum.get(boost))That should print:
Value of DEXTERITY: 1By the way, if you want to get the name from the value, you can do this:
var value = MyEnum.DEXTERITYprint("Name of ", value, ": ", MyEnum.keys()[value])That should print:
Name of 1: DEXTERITYWhat you are getting is just a regular dictionary preset with the contents of the enum. So, we can ask it about all the values:
for boost in MyEnum:print(boost)Which will print:
STRENGTHDEXTERITYCONSTITUTIONINTELLIGENCEWISDOMCHARISMAAnd we can also ask it if it has a particular one, for example print(MyEnum.has("ENDURANCE")) prints False.
And yes you could edit the dictionary. It is just a dictionary you get initialized with the values of the enum.
