# Minecraft Detectorists

Another simple minecraft game, this time using Pythagoras' theorem to work out distances between two points.

We randomly bury a piece of treasure - a gold block, a diamond, whatever - then give the player clues about how far away they are from it. The "game" ends when they dig up the block.

```
import mcpi.minecraft as minecraft
import mcpi.block as block
import time
import random
import math
def random_underground_position():
return minecraft.Vec3(random.randint(-100, 100), random.randint(-20, 0), random.randint(-100, 100))
def distance_to_treasure(player, treasure):
dx = player.x - treasure.x
dy = player.y - treasure.y
dz = player.z - treasure.z
return math.ceil(math.sqrt((dx*dx) + (dy*dy) + (dz*dz)))
world = minecraft.Minecraft.create()
treasure = random_underground_position()
world.setBlock(treasure.x, treasure.y, treasure.z, block.GOLD_BLOCK)
last_position = world.player.getTilePos()
last_distance = distance_to_treasure(last_position, treasure)
world.postToChat("Find the gold!")
detectoring = True
while detectoring:
position = world.player.getTilePos()
if position != last_position:
distance = distance_to_treasure(position, treasure)
if distance < 5:
detectoring = False
else:
message = ""
if distance < last_distance:
message = "Warmer " + str(distance)
elif distance > last_distance:
message = "Colder " + str(distance)
world.postToChat(message)
last_distance = distance
last_position = position
time.sleep(2)
world.postToChat("You found the treasure")
```

Inspired by code I originally saw at Martin O'Hanlon's excellent Stuff About Code.
