Minecraft Pi Edition API

[tewe]

Hi!

I am a beginner when it comes to Python, I am trying to learn it using the Minecraft API. I am trying to make a program that places a GoldBlock instead of every block I step on. This is the code that I have written:

Code: Select all

import minecraft.minecraft as minecraft
import minecraft.block as block
import time

mc = minecraft.Minecraft.create()
playerPosition = mc.player.getPos()
post = mc.postToChat
blockType = mc.getBlock(playerPosition.x, playerPosition.y -1, playerPosition.z)

if __name__ == "__main__":


	while ('True'):
		if not blockType == 9 or blockType == 0:
			mc.setBlock(playerPosition.x, playerPosition.y -1, playerPosition.z,block.GOLD_BLOCK)

Code: Select all

	while ('True'):
		if not blockType == 9 or blockType == 0:
			mc.setBlock(playerPosition.x, playerPosition.y -1, playerPosition.z,block.GOLD_BLOCK)

In the later code is a WhileLoop. I am pretty sure that it is this part of the code that is incorrect. When I run the program from LXTerminal it runs properly. But it is only the block that the player stands on when the program executes that is transformed into gold.

I really appreciate all of your help!

You only read mc.getPos() & mc.getBlock() once.

Move those calls inside your while loop so that as you move you re-read the coordinates of the block to turn to gold.

As an aside, your code says:

Code: Select all

while ('True')

True in inverted commas is the string True, rather than the True/False boolean value. You'd therefore normally have:

Code: Select all

while True:

However the effect is the same, as any string other than an empty string is considered True in Python. See https://docs.python.org/2/library/stdtypes.html

Thank you for the help but it is still not working. I have tried to write another bit of code:

Code: Select all

	while ('True'):
		if not blockType == 9 or blockType == 0:
			mc.setBlock(playerPosition.x, playerPosition.y -1, playerPosition.z,block.GOLD_BLOCK)
                        mc.postToChat ('GOLD!')

I added mc.postToChat ('GOLD!'). That command repeats over and over again. So it is not the loop that is the incorrect part I think.

Did you see Dougie's comment?

These lines:

Code: Select all

playerPosition = mc.player.getPos()
blockType = mc.getBlock(playerPosition.x, playerPosition.y -1, playerPosition.z)

needs to be inside the While loop.

you're checking whether blockType is equal to a certain value, but you're not updating blockType to reflect the fact that your player is moving.

Also you probably want to use getTilePos rather than getPos as it will give you integers rather than floats.

Code: Select all

playerPosition = mc.player.getTilePos()
blockType = mc.getBlock(playerPosition.x, playerPosition.y - 1, playerPosition.z)
