Description

This is a basic interface to the MineCraft-Pi API. The intention is to build higher-level commands (and add support for missing commands), but you can say

{-# LANGUAGE RecordWildCards #-}

module Main where

import Control.Monad (when)

import Data.MineCraft.Pi.Block 
import Data.MineCraft.Pi.Player
import Data.MineCraft.Pi.Types

import Network.MineCraft.Pi.Client

-- | Returns @True@ if the player is standing on gold ore.
isOnGold :: IO Bool
isOnGold = runMCPI $ do
    Pos {..} <- getPlayerTile
    bType <- getBlock $ Pos _x _y (_z-1)
    return (bType == goldOre)

main :: IO ()
main = do
    flag <- isOnGold
    when flag $ putStrLn "Look down!"

Building

• Install ghc and the Haskell platform

  sudo apt-get install ghc haskell-platform
  

• Download the package

  cabal unpack mcpi
  

which will create the directory mcpi-<version>. If you instead say

    cabal install mcpi

then the package will be built and installed into the system; by using unpack you just build a local copy.

• Build the package

  cd mcpi-<version>
  cabal configure
  cabal build
  

You may need to install the pipes package before the above will run:

    cabal install pipes

• Run one of the examples

  ./dist/build/isongold/isongold 
  

Examples

Several examples are included in the examples/ directory. They are built, and installed, by default. To avoid building them tun off the build-examples flag at configure time by saying

cabal configure -f-build-examples
