3 new scripts from goldfish – HelloWorld, clearZone and drawBuilding!

Ryan (goldfish) has submitted 3 new programs — and he has my many thanks for doing so by pushing his changed to the github repo and making them compatible with the other scripts!!

Here’s what he’s contributed:

gf_helloworld.py

This is a simple program that connects to the minecraft server and does a quick chat — this is a great template for starting new programs…

#! /usr/bin/python
import mcpi.minecraft as minecraft
import server

""" hello world test app

    @author: goldfish"""

mc = minecraft.Minecraft.create( server.address )
mc.postToChat("Hello, Minecraft!")

gf_clearZone.py

This one creates a 20×20 block and adds a stone floor.  Even better you can import it and call clearZone(x1,y1,x2,y2) to create a clear zone of the size you specify.

#! /usr/bin/python
import mcpi.minecraft as minecraft
import mcpi.block as block
import server

""" clearZone clears an area and sets a stone floor
    takes two x,z pairs clears everything above 0y and then sets
    a stone floor at -1y
    @author: goldfish"""

def clearZone( alocx, alocz, blocx, blocz ):
    mc.setBlocks( alocx, 0, alocz, blocx, 64, blocz, block.AIR )
    mc.setBlocks( alocx, -1, alocz, blocx, -1, blocz, block.STONE )

if __name__ == "__main__":
    mc = minecraft.Minecraft.create( server.address )
    clearZone( -20, -20, 20, 20 )

gf_drawbuilding.py

This one creates a building with floors and windows in it — or you can call it again with your own parameters.  Call the following function..

drawBuilding( locx, locy, locz, floors, width, depth, floorheight, wallmaterial, floormaterial)

#! /usr/bin/python
import mcpi.minecraft as minecraft
import mcpi.block as block
import server
import random

""" draw a building

    @author: goldfish"""

def drawBuilding( locx, locy, locz, floors, width, depth, floorheight, wallmaterial, floormaterial ):
    topx = locx+width
    topy = locy+((floorheight+1)*floors)
    topz = locz+depth
    #draw building shell
    mc.setBlocks( locx, locy, locz, topx, topy, topz, wallmaterial )
    mc.setBlocks( locx+1, locy+1, locz+1, topx-1, topy-1, topz-1, block.AIR )
    #draw floors
    if( floors > 1 ):
        for i in range( floors -1 ):
            floorYloc = locy+( (floorheight+1)*(i+1) )
            mc.setBlocks( locx+1, floorYloc, locz+1, topx-1, floorYloc, topz-1, floormaterial )
    #draw door
    doorloc = random.randint( 1, width-2 )
    mc.setBlock( locx, locy+1, locz+doorloc, block.AIR )
    mc.setBlock( locx, locy+2, locz+doorloc, block.AIR )
    #draw front windows
    if( floors > 1 ):
        for i in range( floors-1 ):
            windowYloc = locy+2+( (floorheight+1)*(i+1) )
            for j in range( floorheight-1 ):
                mc.setBlocks( locx, windowYloc+j , locz+1, locx, windowYloc+j, locz+(width-1), block.GLASS_PANE )
    #draw back windows
    if( floors > 1 ):
        for i in range( floors-1 ):
            windowYloc = locy+2+( (floorheight+1)*(i+1) )
            for j in range( floorheight-1 ):
                mc.setBlocks( locx+depth, windowYloc+j , locz+1, locx+depth, windowYloc+j, locz+(width-1), block.GLASS_PANE )
    #connect levels with ladder
    #mc.setBlocks( topx-1, locy+1, topz-1, topx-1, topy-1, topz-1, block.LADDER )

if __name__ == "__main__":
    mc = minecraft.Minecraft.create( server.address )
    drawBuilding( 0, 0, 0, 5, 5, 5, 3, block.STONE, block.WOOD_PLANKS )
