Hi,

the ScriptObject can work as a "State Machine".

You need to add a "state" member variable to your script. Depending on this state
you can start the next interactor in "start_next_input". With an initial value of "xxx" it looks like

match self.state:
    case xxx:
        self.script_object_interactor = ...

        self.state = yyy

    case yyy:
        self.script_object_interactor = ...

        self.state = zzz

    case zzz:
        ...

Best regards
Horst

Hi,

The switching between input steps must all be done in the start_next_input(). Only the first input step should be started in the start_input(). The implementation should involve keeping track of what input step is currently active. You can achieve it by defining an instance attribute "current_input_step" in your ScriptObject class and changing it whenever a new input step is started.

begin with defining the enumeration class representing your input steps:

class InputStep(IntEnum):
    Undefined = 0
    First  = 1
    Second = 2
    Third  = 3
    Fourth = 4
    Fifth  = 5

Second, define the instance attributes in your ScriptObject class for storing the input results:

def __init__(self,build_ele, script_object_data):

    super().__init__(script_object_data)

    # set initial values
    self.build_ele              = build_ele
    self.first_input_result     = MultiElementSelectInteractorResult()
    self.second_input_result    = PointInteractorResult()
    self.third_input_result     = SingleElementSelectResult()
    self.fourth_input_result    = PointInteractorResult()
    self.fifth_input_result     = SingleElementSelectResult()

    self.current_input_step     = InputStep.Undefined    # here the attribute for keeping track of the current input step

Start the first input step:

def start_input(self):
    self.script_object_interactor = MultiElementSelectInteractor(
        self.first_input_result,
        prompt_msg="First, select some elements")
    self.current_input_step = InputStep.First     # keep track of the current input step!

Switch the input step, depending on what is the current one. Everything in the start_next_input():

def start_next_input(self):
    """Start the next input step"""

    if self.current_input_step == InputStep.First:
        # when there is a valid result for the first input step, start the second input step
        self.script_object_interactor = PointInteractor(
            self.second_input_result, False,
            request_text="Now, select a point")
        self.current_input_step = InputStep.Second
        return

    if self.current_input_step == InputStep.Second:
        # when there is a valid result for the second input step, start the third input step
        self.script_object_interactor = SingleElementSelectInteractor(
            self.third_input_result,
            prompt_msg="Next, select an element")
        self.current_input_step = InputStep.Third
        return
    ...
