Project 2 - Bit Problems

Inverting the World

Bit is in a world with a blue picture on a white background:

Invert the entire world. Blue should become empty, and empty should become blue. The final world should look like this:

There is a second world that looks like this:

and when Bit is done it should look like this:

You can find starter code in invert.py.

Blue S

Move Bit to the right edge of the grid. Along the way, if Bit encounters a green square, draw a blue “S”. The bends in the “S” are marked by blocked squares.

The first world looks like this:

and at the end should look like this:

The second world looks like this:

You can find starter code in blue_s.py.

Escape

Bit is exploring a cave and finds a secret gem that has been hidden for centuries:

Unfortunately, his enemies have started to flood the cave with water! Help Bit escape by (1) picking up the gem, (2) running through the cave, (3) climbing the moss-covered cliff at the end. The final world should look like this:

The water has followed Bit as they run, and Bit has put down the gem to examine it.

There is a second world that looks like this:

and the at the end should look like this:

Note that the gem may be a ruby (red) or an emerald (green).

You can find starter code in escape.py.

Pools of Gems

When Bit was examining the gem, they discovered a secret ingredient that lets them replicate gems. So Bit goes to their backyard, where there are a bunch of empty holes. Bit picks up a gem, then fills the next pool with copies of that same gem.

One of the starting worlds looks like this:

at the end, the world should look like this:

The other starting world looks like this:

at the end, the world should look like this:
