.get_memory()

.get_memory()

A game for Ludum Dare 44 made with Pygame and Qiskit.

How to run

You'll need Python3 to run this game.

First download the source and then cd into the folder using a terminal. To install the dependencies, use the command

```python3 -m pip install -r requirements.txt```

To play the game, use the command

```python3 run_game.py```

The game is played using two windows: the terminal window for text and the pygame window for visuals.

How to play

You move by pressing *q*, *w*, *a* and *d*. You can also teleport with the space bar. The rest is for you to figure out.

Why does this game exist?

There are three reasons that this game exists, and which led to it being what it is.

1. It was built during the Ludum Dare 44 game jam, which had the theme "Your life is currency".

2. It was made as an example of using terrain generated by a quantum programs, by the method described in this blog post.

3. It was made to explore the kinds of labyrinths generated by the classic one-line Commodore 64 program

```10 PRINT CHR$(205.5+RND(1)); : GOTO 10```

This was ported into the following quantum program, which is the basis for the labyrinths in the game

```from qiskit import *; ''.join( [ '╱'*(b=='0') + '╲'*(b=='1') for b in execute(QuantumCircuit().from_qasm_str('include "qelib1.inc";qreg q[1];creg c[1];h q[0];measure q -> c;'),Aer.get_backend('qasm_simulator'),shots=1024,memory=True).result().get_memory()])```

The original program is referred to simply as ```10 PRINT``` in this book about it, after the first part of the program. Inspired by this, I name my port of the program after a part near the end: ```.get_memory()```. This is also used as the name of the game.
