	var target_node = blackboard.get_node(self.target)
	if target_node == null

		return FAILURE

Hello, I starting to use your addon and i'm just testing some examples and when I used a _init function in a action I have this error :

E 0:00:00:0339   _create_instance: Error constructing a GDScriptInstance: 'Node(walking_action.gd)::_init': Method expected 1 arguments, but called with 0
  <C++ Error>    Method/function failed. Returning: nullptr
  <C++ Source>   modules/gdscript/gdscript.cpp:196 @ _create_instance()

and Godot open the sequence.gd file on this line :

		if c != running_child:
			c.before_run(actor, blackboard)

Sure that I have forget something but I don't know what :-(

it looks like in the file modules/gdscript/gdscript.cpp on line 196, the script calls the function _create_instance without any arguments, which you can see because the error message says that the line says _create_instance() without any args in the parentheses. I am not sure how to fix that, but i can, and just explained what is wrong.

In Godot, you cannot have an _init() function with more than 0 args when you wish nodes to be instantiated via scene tree. When adding nodes to your scene, Godot will call _init() for you but always with no arguments. By overriding the _init you basically prevent Godot from doing that.
