Prerequisites

This example requires an installation of IC SDK and Node.js

Running the project locally

• To test project locally, open terminal window and navigate into the folder containing project's files
• Use the following commands:

# Installs necessary node modules
npm install

# Starts the local replica in background
dfx start --background --clean

# Creates new identity for minting account and exports its ID as "MINTER_ACCOUNT_ID" variable
dfx identity new minter --storage-mode=plaintext
dfx identity use minter
export MINTER_ACCOUNT_ID=$(dfx ledger account-id)

# Exports default identity's account ID as "DEFAULT_ACCOUNT_ID" variable
dfx identity use default
export DEFAULT_ACCOUNT_ID=$(dfx ledger account-id)

# Deploys ledger canister with archiving options enabled
dfx deploy --specified-id ryjl3-tyaaa-aaaaa-aaaba-cai icp_ledger --argument "
  (variant {
    Init = record {
      minting_account = \"$MINTER_ACCOUNT_ID\";
      initial_values = vec {
        record {
          \"$DEFAULT_ACCOUNT_ID\";
          record {
            e8s = 100_000_000_000 : nat64;
          };
        };
      };
      send_whitelist = vec {};
      transfer_fee = opt record {
        e8s = 10_000 : nat64;
      };
      token_symbol = opt \"LICP\";
      token_name = opt \"Local ICP\";
    }
  })

# Deploys canisters to the replica and generates candid interface
dfx deploy

# Starts a development server at  http://localhost:8080 proxying API requests to the replica at port 4943
npm start

# For local testing, you should login in game with multiple identity and transfer some LICP to their accounts to be able to participate in game)
# Transfers 10 LICP to specified account address
