I'm guessing you are also using numpy and that you want arrays (or matrices) for
the sake of either (a) matrix and array functions or (b) much greater processing
speed.
Add
from numpy import *
Then hat you can do is go back and forth: Build what you intend to be an array,
but build it as
You might try fixing up the following. I did not match the scale to what you
are looking for. But the trick is to take advantage of the time module's association
of numbers with dates:
import time
import random

Think "linear relation".
For each of your new "horizontal" coordinates, there is a linear relation changing the "old" coordinate into the pixel coordinate of the pygame map.
You have to find the intercept and the slope of that linear relation.
There will be a second, unrelated "linear transform

I'm using, perhaps misusing numpy which is eating up the memory and, eventually
crashing my program.
Isolating it, the following piece of code continually eats memory. Is it my
program or what ...?
Thanks
