Here is a code

testing

class_name Action
# Reference is the default type you extend in Godot, even if you omit this line.
# Godot allocates and frees instances of a Reference from memory for you. extends Reference

# Emitted when the action finished playing.
signal finished

var _data: ActionData
var _actor
var _targets := []


# The constructor allows you to create actions from code like so:
# var action := Action.new(data, battler, targets)
func _init(data: ActionData, actor, targets: Array) -> void:
_data = data
_actor = actor
_targets = targets

Nick, what do you think I'm doing wrong to have the code looking great, but when I hit save it disappears?
