This talk will dive into how to build an AI for a turn based strategy game from scratch. When I started building Athena Crisis, I had no idea how to build an AI. All the available resources were too complex or confusing, so I just started building it based on how I would play the game. If you would like to learn how to build an AI, check out this talk!

Video Summary and Transcription

Join Christoph from Nakazawa Tech in building the AI for Athena Crisis, a game where the AI performs actions just like a player. Learn about the importance of abstractions, primitives, and search algorithms in building an AI for a video game. Explore the architecture of Athena Crisis, which uses immutable persistent data structures and optimistic updates. Discover how to implement AI behaviors and create a class for the AI. Find out how to analyze units, assign weights, and prioritize actions based on the game state. Consider the next steps in building the AI and explore the possibility of building an AI for a real-time strategy game.

1. Introduction to Building AI for Athena Crisis

Short description:

Hello! Join me for my talk about building the AI for Athena Crisis. I'm Christoph from Nakazawa Tech. If you haven't heard about Athena Crisis before, I recommend watching my previous talk. I have experience managing React Native and JavaScript infrastructure teams at Facebook. We offer leadership coaching and JavaScript problem-solving at Nakazawa Tech. Reach out at nakazawa.dev.

Oh, hello there. I'm just playing Athena Crisis on my Steam deck. Thanks so much for joining me for my talk about building the AI for Athena Crisis. I'm Christoph, and I run a small startup in Tokyo called Nakazawa Tech.

If you haven't heard about Athena Crisis before, recently at React Summit a few months ago, I did a talk that explains how the game is being built, and it's all built with JavaScript, React, and CSS. I highly recommend if you haven't seen it, to go back and watch that talk.

If we go even further back, if you have never worked with me before or if you don't know me, I used to manage the React Native and JavaScript infrastructure teams at Facebook, and I built a JustJavaScript testing framework. We do a lot of stuff at Nakazawa Tech, including building video games, but we do leadership coaching, and we can help you with your JavaScript problems, with developer velocity, productivity, or help you with whatever problems you might run into while building JavaScript-based applications. Please work with us, please reach out at nakazawa.dev.

2. Understanding Athena Crisis and Building an AI

Short description:

Before we dive into building an AI for Athena Crisis, let's understand what Athena Crisis is. In the game, I can jump into a game from the menu and play. After my turn, the AI takes over and performs all the necessary actions, just like a player. It can attack, move, and capture buildings. Now, let's explore how to build such an AI.

First, before we get into building an AI for Athena Crisis, let's spend a bit of time figuring out what Athena Crisis is. I'm just here in the game in the menu, and you can see the overview page right now, and I can jump into a game from right here. And just like that, I can play the game. Not all of the attacks have sounds yet, but some of them do. But the cool thing is, once I finish my turn, let me just build a few units. When I finish my turn, the AI takes over and takes care of their turn. It does attacks, it moves, it can capture buildings, it can do everything that a player can also do. Turn off the music again.

React provides a contract to developers- uphold certain rules, and React can efficiently and correctly update the UI. In this talk we'll explore these rules in depth, understanding the reasoning behind them and how they unlock new directions such as automatic memoization.

Too much JavaScript is getting you down? New frameworks promising no JavaScript look interesting, but you have an existing React application to maintain. What if Qwik React is your answer for faster applications startup and better user experience? Qwik React allows you to easily turn your React application into a collection of islands, which can be SSRed and delayed hydrated, and in some instances, hydration skipped altogether. And all of this in an incremental way without a rewrite.

SolidJS: Why All the Suspense?
Top Content
Solid caught the eye of the frontend community by re-popularizing reactive programming with its compelling use of Signals to render without re-renders. We've seen them adopted in the past year in everything from Preact to Angular. Signals offer a powerful set of primitives that ensure that your UI is in sync with your state independent of components. A universal language for the frontend user interface.
But what about Async? How do we manage to orchestrate data loading and mutation, server rendering, and streaming? Ryan Carniato, creator of SolidJS, takes a look at a different primitive. One that is often misunderstood but is as powerful in its use. Join him as he shows what all the Suspense is about.

Jotai is a state management library. We have been developing it primarily for React, but it's conceptually not tied to React. It this talk, we will see how Jotai atoms work and learn about the mental model we should have. Atoms are framework-agnostic abstraction to represent states, and they are basically just functions. Understanding the atom abstraction will help designing and implementing states in your applications with Jotai

A Framework for Managing Technical Debt
Top Content
Let’s face it: technical debt is inevitable and rewriting your code every 6 months is not an option. Refactoring is a complex topic that doesn't have a one-size-fits-all solution. Frontend applications are particularly sensitive because of frequent requirements and user flows changes. New abstractions, updated patterns and cleaning up those old functions - it all sounds great on paper, but it often fails in practice: todos accumulate, tickets end up rotting in the backlog and legacy code crops up in every corner of your codebase. So a process of continuous refactoring is the only weapon you have against tech debt.In the past three years, I’ve been exploring different strategies and processes for refactoring code. In this talk I will describe the key components of a framework for tackling refactoring and I will share some of the learnings accumulated along the way. Hopefully, this will help you in your quest of improving the code quality of your codebases.
