Interacting with
Blocks
ONE WAY YOU
can make a Minecraft game more interesting is to make it change
what it does based on what is going on around your player. As you move around the
game world, the choices that you are faced with depend on what you have already done
before, making the game slightly different every time you play it. The Minecraft API
allows you to interact with blocks by finding out what block type you are standing on
and detecting when you hit a block with your sword.
In this adventure, you will first learn the basics of interacting with blocks by writing a
magic bridge program. This bridge is special, because as you walk on water or walk into
the sky, a bridge magically appears in front of you to keep you safe. Soon your Minecraft
world will fill up with bridges. Version 2 of your magic bridge builder will use a Python
list to remember where you built the bridge and will make it do a disappearing act right
before your eyes when you land on safe ground again!
Finally, you learn how to sense that a block has been hit, and then build an exciting
treasure hunt game using your magic bridge to find and collect treasure that appears
randomly in the sky, complete with a homing beacon and a score.
In this adventure you will work just like a real software engineer, building up a large
program one function at a time, and finally stitching it all together at the end to make
an exciting larger program. Fasten your seatbelt and take careful note of the instruc-
tions. It's going to be an exciting journey into the sky!
