stateMachine | A simple state machine library

I'm building some classes within unity to define the mechanics individually, and transition between each for easier and cleaner code.

What I wanna know, is when should I be using a constructor to pass variables around, and when to use protected variables. What are the pros and cons of each, and what should I know about them? Also what should I lean towards, like what's practical?

Previously I'd pass these variables into the PlayerState constructor, then in my classes that extend from my PlayerState would follow suit. But if they're protected variables I don't need to pass them into the constructor to access them, and I was wondering what should I do? using UnityEngine;

The new way I'm doing it:

I'm trying to get a property from MongoDB (mongoose) using the Model.findById() method. When I console.log the response, everything looks fine. But I cannot access it's properties.

I am using AWS Lambda within a StepFunctions state machine.

The template below worked fine until I had to change the name of the LogToDatabase function.

Now the Publish to AWS wizard in VS2019 gives this error:

Failed to create CloudFormation change set: Template error: instance of Fn::Sub references invalid resource attribute LogToDatabase.Arn

Any ideas?

Here's my StepFunctions state machine:

How do I use PermitIf with SetTriggerParameters?

In this example I'm modelling a motor, which can go forward, backwards, or off (not moving). Forwards and backwards can be a double speed, so therefore I need SetTriggerParameters. Setting the speed to 0, however, turns the motor off.

I wish to disallow being able to trigger TurnOnForwards or TurnOnBackwards with an argument of 0 - I want the TurnOff trigger to be explicitly the way to turn the motor off. Otherwise, you arrive at the situation where the current state is Forwards/Backwards but with a speed of 0.

This is the error I get:

CS1503 Argument 1: cannot convert from 'UserQuery.Triggers' to 'Stateless.StateMachine.TriggerWithParameters'

I have a WPF desktop application that consumes Web API over VPN. Relevant details:

• App type: WPF
• .NET: 4.6.2
• OS: Windows 10
• VPN: Palo Alto GlobalProtect

And sometimes it throws an uncaught exception from HttpClient on application start:

I did git push heroku master for the second time. But I got the error cannot find module .... For the first time, I succeeded.

How can I fix this? Thanks.

I have an AWS steps function defined using this Serverless plugin with 3 steps (FirstStep -> Worker -> EndStep -> Done):

I have a gateway service and a microservice customer

The Gateway service call a method from Customer microservices.

The customer service entry point looks like this :

I've created a AWS Cloudformation Stack with a template.yaml file that implements several lambda functions. There are several Python functions that some/all of the lambda functions use. Is there a place that I can store common functions? If you think the answer involves layers please address how to include and use custom functions (since the main workflow for layers supports the usual pip python site-package - I'm curious about reusing my own functions).
