v4.2.1.stable
Is it possible to set a default variable in array or dictionary when adding a new element.
For example, an array for strings has a default variable of string so when pressing “Add Element”, it creates an element that already has a string.
I believe you are talking about @export?
For arrays you can add a type specifier:
@export var a:Array[int]
For dictionaries there is no type specifier in 4.3. However typed dictionaries are ready and will be in the next version (4.4 I think).
If this isn’t what you mean could you elaborate some more please?
when you go with @export var arr : Array[String] and click on “Add Element” in your editor’s inspector, it will create a new string that’s empty. It’s not possible to preset a value for new array items.
If you don’t really need the actual value of the String and merely require some preset identifiers, you could go with enums instead
enum VALUES { yourDefault, option1, option2, option3 }
@export var arr: Array[VALUES]
that way, everytime you add a new array element, it will preset “your Default” but it restricts you from choosing any other value that’s not in the enum which is most likely not what you want.
