simple mcpi-gpio program

import time
import RPi.GPIO as GPIO # import the GPIO module
import minecraft
import block
import time

mc = minecraft.Minecraft.create()
GPIO.setmode(GPIO.BCM) # sets the mode to BCM (meaning that pin 17 refers to the 17th pin AKA GPIO 11
GPIO.setup(17, GPIO.OUT) # marks pin 17 as an output pin
GPIO.output(17, True) # sets pin 17 to true. Since pin 17 (GPIO 11) is marked as output, this will turn on your LED

while True:
        time.sleep(0.1)
        playerPos = mc.player.getPos()
        y = int(playerPos.y)
        if y > 20:
                GPIO.output(17, True)
        else:
                GPIO.output(17, False)
