For part 2, I’d like to cover a tutorial in matplotlib that is our boid GUI. As far as my Googling skills could take me, I couldn’t find an animation similar to what I was looking for: two separate scatter plots that logically trace each other in an endless loop. The closest I could find was a cool rain simulation that used a scatter plot and randomly changed certain properties. Here is a time lapse video of my process from start to finish.
So first thing is housekeeping. There are a few imports that need to happen. I’m on a MacOS and using PyCharm as my IDE. I did get a few errors installing the following:
If you’re getting the same problem, try running
It’s likely numpy was trying to install for Python 2.7 instead of Python 3. Next, we have to set up the plot.
Matplotlib requires a figure object, think “blank canvas”. We can then draw our axes and data points over it. Creating an axes object lets us customize the x-y limit and appearance. Similarly, data points must also be objects. We achieve this by creating zero arrays in numpy. These are
