Overview

A template for a Loom DAppChain with a Unity client. Contains:

  • Template Blueprint Solidity contract implementing a basic string-to-string map. Perfect as a starting point.
  • Pre-configured Truffle project that automatically extracts ABIs and binaries of compiled contracts into corresponding folders.
  • Pre-configured optimally setup Unity project with Blueprint contract test scene, and an already included Loom SDK.

Getting the Template

First, you need to install Truffle, if it isn't installed already:

npm install -g truffle

After that, you can download the template itself:

git clone https://github.com/loomnetwork/loom-unity-project-template.git

Feel free to rename the loom-unity-project-template folder right away according to the name of your project.

Building the Truffle Project

# Build the Truffle project. This will extract the ABI files to the Unity client,
# and compiled contracts to the DAppChain/build/ directory

cd Truffle
truffle build

Running the DAppChain

# Start the Loom DAppChain. Loom binary will be downloaded automatically

cd DAppChain
./start-chain.sh

Running the Unity client

Open the Unity project located in UnityClient. Open the Blueprint/BlueprintTest scene and run/build it.

Workflow

  1. Make changes to the contracts.
  2. Build the Truffle project using truffle build.
  3. Start the Loom DAppChain using DAppChain/start-chain.sh.
  4. Make changes to the Unity client project.
