A problem with 'blocksBetween' name in the code

[Max Altynnikov]

Hello!

I'm learning Advetures in Minecraft Second Edition and am stuck on a weird error saying that a name is not defined.

The problem block of code is below:

for blockBetween in blocksBetween[:-1]:

        mc.setBlock(friend.x, friend.y, friend.z, block.AIR.id)

        friend = blockBetween.clone()

        friend.y = c.getHeight(friend.x, friend.z)

        mc.setBlock(friend.x, friend.y, friend.z,

                    block.DIAMOND_BLOCK.id)

        time.sleep(0.25)

    target = friend.clone()

    time.sleep(0.25)

After running the code I get an error message like this:

for blockBetween in blocksBetween[:-1]:

NameError: name 'blocksBetween' is not defined

I was carefully following the book before this error occured and the code worked perfectly before this last cycle :)

Any help is greatly appreciated!

Thnaks!

Hi,

The error is telling you that the list blocksBetween doesnt exist in your program.

It should have been created on the previous line when you used 

blocksBetween = mcdrawing.getLine(....)

I would check that your spelling of blocksBetween is correct.
