Dojo Starter: Official Guide

The official Dojo Starter guide, the quickest and most streamlined way to get your Dojo Autonomous World up and running. This guide will assist you with the initial setup, from cloning the repository to deploying your world.

The Dojo Starter contains the minimum required code to bootstrap your Dojo Autonomous World. This starter package is included in the dojoup binary. For more detailed instructions, please refer to the official Dojo Book here.

Prerequisites

• Rust - install here
• Cairo language server - install here

Step-by-Step Guide

Follow the steps below to setup and run your first Autonomous World.

Step 1: Install dojoup

Start by installing dojoup. This cli tool is a critical component when building with Dojo. It manages dependencies and helps in building your project. Run the following command in your terminal:

curl -L https://install.dojoengine.org | bash
dojoup

The command downloads the dojoup installation script and executes it.

Step 2: Clone the Repository

The next step is to clone the repository to your local machine. Open your terminal and type the following command:

git clone https://github.com/dojoengine/dojo-starter.git && cd dojo-starter

This command will create a local copy of the Dojo Starter repository and enter the project directory.

Step 3: Build the Example World

With dojoup installed, you can now build your example world using the following command:

sozo build

This command compiles your project and prepares it for execution.

Step 4: Start Katana RPC

Katana RPC is the communication layer for your Dojo World. It allows different components of your world to communicate with each other. To start Katana RPC, use the following command:

katana --allow-zero-max-fee

Step 5: Migrate (Deploy) the World

Finally, deploy your world using the sozo migrate command. This command, deploys your world to Katana!

sozo migrate

Congratulations! You've successfully setup and deployed your first Dojo Autonomous World.

Interacting With Your Local World

Explore and interact with your locally deployed world! This guide will help you fetch schemas, inspect entities, and execute actions using sozo.

If you have followed the example exactly and deployed on Katana, you can use the world address generated to either:

• use as an argument to --world when calling sozo commands

• add it to Scarb.toml under [tool.dojo.env] table like so

  [tool.dojo.env]
  world_address = "<world_address>"

• set it as an environment variable

  export DOJO_WORLD_ADDRESS="<world_address>"

Fetching Component Schemas

Let's start by fetching the schema for the Moves component. Use the following command

sozo component schema Moves

You should get this in return:

struct Moves {
   remaining: u8
}

This structure indicates that the Moves component keeps track of the remaining moves as an 8-bit unsigned integer.

Inspecting an Entity's Component

Let's check the remaining moves for an entity. In our examples, the entity is based on the caller address, so we'll use the address of the first Katana account as an example.

sozo component entity Moves 0x03ee9e18edc71a6df30ac3aca2e0b02a198fbce19b7480a63a0d71cbd76652e0

If you haven't made an entity yet, it will return 0.

Adding an Entity

No entity? No problem! You can add an entity to the world by executing the spawn system. Remember, there's no need to pass any call data as the system uses the caller's address for the database.

sozo execute spawn

Refetching an Entity's Component

After adding an entity, let's refetch the remaining moves with the same command we used earlier:

sozo component entity Moves 0x03ee9e18edc71a6df30ac3aca2e0b02a198fbce19b7480a63a0d71cbd76652e0

Passing the world address as an argument

We can get the same results by executing this command

sozo component entity Moves --world <WORLD_ADDRESS> 0x03ee9e18edc71a6df30ac3aca2e0b02a198fbce19b7480a63a0d71cbd76652e0

Congratulations! You now have 10 remaining moves! You've made it this far, keep up the momentum and keep exploring your world!

Make sure to read the Offical Dojo Book for detailed instructions including theory and best practices.
