Game-of-Life (GoL) Challenge

This application allows users to play with Conway's Game of Life (GoL) and solve specific puzzles to earn points.

Usage

Setting up

Make sure you have the linera binary in your PATH, and that it is compatible with your linera-sdk version.

For scripting purposes, we also assume that the BASH function linera_spawn is defined. From the root of Linera repository, this can be achieved as follows:

bash

export PATH="$PWD/target/debug:$PATH"
source /dev/stdin <<<"$(linera net helper 2>/dev/null)"

Start the local Linera network and run a faucet:

bash

FAUCET_PORT=8079
FAUCET_URL=http://localhost:$FAUCET_PORT
linera_spawn linera net up --with-faucet --faucet-port $FAUCET_PORT

# If you're using a testnet, run this instead:
#   LINERA_TMP_DIR=$(mktemp -d)
#   FAUCET_URL=https://faucet.testnet-XXX.linera.net  # for some value XXX

Enable logs for user applications:

bash

export LINERA_APPLICATION_LOGS=true

Create the user wallets and add chains to them:

bash

export LINERA_WALLET_1="$LINERA_TMP_DIR/wallet_1.json"
export LINERA_KEYSTORE_1="$LINERA_TMP_DIR/keystore_1.json"
export LINERA_STORAGE_1="rocksdb:$LINERA_TMP_DIR/client_1.db"
export LINERA_WALLET_2="$LINERA_TMP_DIR/wallet_2.json"
export LINERA_KEYSTORE_2="$LINERA_TMP_DIR/keystore_2.json"
export LINERA_STORAGE_2="rocksdb:$LINERA_TMP_DIR/client_2.db"

linera --with-wallet 1 wallet init --faucet $FAUCET_URL
linera --with-wallet 2 wallet init --faucet $FAUCET_URL

INFO_1=($(linera --with-wallet 1 wallet request-chain --faucet $FAUCET_URL))
# INFO_2=($(linera --with-wallet 2 wallet request-chain --faucet $FAUCET_URL))
CHAIN_1="${INFO_1[0]}"
# CHAIN_2="${INFO_2[0]}"
OWNER_1="${INFO_1[1]}"
# OWNER_2="${INFO_2[1]}"

Note that linera --with-wallet 1 or linera -w1 is equivalent to linera --wallet "$LINERA_WALLET_1" --keystore "$LINERA_KEYSTORE_1" --storage "$LINERA_STORAGE_1".

Creating the GoL challenge application

We use the default chain of the first wallet to create the application on it and start the node service.

bash

APP_ID=$(linera -w1 --wait-for-outgoing-messages \
  project publish-and-create examples/game-of-life-challenge gol_challenge $CHAIN_1 \
    --json-argument "null")

linera -w1 service --port 8080 &
sleep 1
