## Prerequisites 

This example requires an installation of [IC SDK](https://internetcomputer.org/docs/current/developer-docs/setup/install/index.mdx) and [Node.js](https://nodejs.org/en/download/)

## Running the project locally

- To test project locally, open terminal window and navigate into the folder containing project's files

- Use the following commands:

```bash

# 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

dfx canister call icp_ledger send_dfx '(record{to="paste_your_deposit_address_here"; memo=0; fee=record{e8s=10_000}; amount=record{e8s=10_00_000_000};})'
