Crafting Core Mechanics: Pong as Your On-Chain Archetype

Let’s dissect a canonical mud tutorial on-chain pong. Define entities: Ball with Position, Velocity components; Paddles linked to player addresses. Systems handle collision, scoring via contract calls, all gas-optimized for L2 bursts.

In MUD, models live in world. ts, encoding arcade logic modularly. Dojo’s executors parallelize updates, ideal for multiplayer volleys. This isn’t mere replication of 1970s cabinets; it’s reimagining them as composable primitives, where scores feed leaderboards or NFT mints.

Master On-Chain Pong: MUD & Dojo on Starknet L2 Guide

Set Up Your Development Environment

Begin by installing essential tools like Rust, Cairo, Scarb, and Dojo CLI, reflecting the modular ECS architecture that underpins autonomous worlds on Starknet. This foundation enables deterministic on-chain logic, aligning data persistence with gameplay mechanics for scalable Ethereum L2 experiences.

Initialize Dojo Project

Leverage Dojo’s world configuration to scaffold a new project via `dojo init pong-game –template blank`. This step establishes the entity-component-system (ECS) pattern at the contract layer, promoting composability and extensibility key to MUD-like autonomous worlds.

Define ECS Models for Pong

Model core entities: Ball (position, velocity), Paddle (position, player ID), and Score. Use Cairo structs in `models.cairo` to encode game state on-chain, ensuring immutability and verifiability—core tenets of on-chain gaming evolution.

Implement Game Systems

Author systems for paddle movement, ball physics, collision detection, and scoring resets. Dojo’s systems execute transactions deterministically on Starknet, enabling multiplayer synchronization without off-chain servers, a paradigm shift from traditional gaming.
