Wizard Masters

Overview

Wizard Masters is a multiplayer battle arena game where players control wizards with different elemental powers. Compete against other players in fast-paced magical combat, mastering spells and tactics to become the ultimate wizard.

Here is my blog post about the journey: https://ertu.dev/posts/i-made-an-online-shooter-game-in-lisp

Project Structure

The project consists of two main components:

• Client: A ClojureScript frontend application using Shadow-CLJS and BabylonJS
• Backend: A Clojure server using Leiningen, Firebase, and Redis (optional)

Prerequisites

Before running the project, ensure you have the following installed:

• Node.js and NPM
• Leiningen (required for running the backend)
• Java Development Kit (JDK) (version 17 or newer recommended)

Installation and Setup

Client Setup

1. Clone the repository
2. Install dependencies:

   npm install
   

3. Start the development server:

   npm run watch
   

   This will compile the ClojureScript code and start a development server.

Backend Setup

1. Navigate to the backend directory:

   cd backend
   

2. Firebase Configuration:

   • Place your Firebase credentials (firestore.json) in the resources/keys folder
   • The file should contain your Firebase service account information

3. Redis Configuration (Optional):

   • Update the Redis URI in backend/src/clj/enion_backend/redis.clj
   • Look for the my-conn-spec-1 definition and replace [YOUR-REDIS-URI] with your Redis URI

4. Start the backend server:

   lein run
   

Connecting to Production Servers

If you don't want to run the backend locally, you can connect the client to production servers by modifying the network configuration:

1. Open src/main/scene/network.cljs
2. Update the get-api-url and get-ws-url functions:
   • Modify the conditions to always return the production URLs instead of the local development ones
   • For example, set config/dev? to false or directly return the production URL

Development

• The client uses Shadow-CLJS for ClojureScript compilation
• The backend uses Leiningen for dependency management and running the server
• Both components have hot-reloading capabilities for rapid development
