# Bullet Combinators

A simple Bullet Hell game written in a functional combinator style in Python

using pygame.

Here is an example pattern which does a sort of figure-eight out of two

octagons. Every time the the bullet moves, it spawns a new bullet which fires

off in a straight line.

```python

Bullet((400, 300)),

    forever(

        sequence(

            repeat(8,

                sequence(

                    repeat(25, forward(3)),

                    rotate(3.14/4),

                    spawn(forever(forward(2)), color=red))),

            rotate(3.14)))

```

This project is inspired by an article on writing a parser with functional

combinators in Arc: . I wanted to write

something with combinators, but was afraid I wouldn't learn anything blindly

copying the parser library. My friend Jace provided this perfect test case

while trying to learn F#.
