godot use enum for export var

Answer: In GDScript, you can use an enum for an exported variable by defining the enum outside the script and then using it as the type for the exported variable. Here's an example:

enum Direction {
    UP,
    DOWN,
    LEFT,
    RIGHT
}

export(Direction) var playerDirection = Direction.UP

This code defines an enum called "Direction" with four possible values (UP, DOWN, LEFT, RIGHT) and then exports a variable called "playerDirection" of type Direction with a default value of Direction.UP.
