5.
Your tower is going to be 50 blocks high, so start building it with a
for
loop that
counts 50 times. Don't forget the colon (
:
) at the end of the line:
for a in range(50):
6.
The next line is indented, because it belongs to the body of the
for
loop. The y
coordinate controls height within the Minecraft world, so add the loop control
variable
a
onto the player's y position. This tells the program to build at an
increasing height in the Minecraft world each time round the loop:
mc.setBlock(pos.x+3, pos.y+a, pos.z, block.STONE.id)
7.
Save the program and run it. Has it worked? Your
for
loop should have created
a massive tower in front of your player, similar to the one in Figure 3-3. Start
counting—is it 50 blocks high?
FIGURE.3-3
This huge tower was created inside the Minecraft world using a
for
loop.
In the previous code, the
for
loop cycles around 50 times, and each time round
the loop, it runs the indented lines below it, such that the
a
variable has a value
one bigger than the previous time round the loop. It adds the value in the
a
variable (the loop control variable) onto the
pos.y
variable (which is the players
height above bedrock). This then creates a tower 50 blocks high!
