This is my seventh year raising money for Johns Hopkins Children’s Center via the Extra Life gaming charity. When I started back then I was brand new to streaming or recording video game play. In fact, just a few years before that I hadn’t even understood the point. I found out that you could somehow display your progress towards fundraising on your screen while you played. I had no idea how to do that and, at the time, I’d only done commandline programs. So I found bfinleyui’s web-based program. I set up XSplit (which I was using at the time) to capture the web pages and was able to have a great first year. The following year he created an app with Adobe Air that was even better. The GUI for this app would become the inspiration for ElDonationTracker; what I aspired to eventually build. My first commit to the repo for ElDonationTracker was that year. I was exploring how to get the API data via the commandline, but I wasn’t too hurried because I had the Adobe Air app. Unfortunately, the following year Adobe killed Adobe Air. So it was now time for me to try and make my own app. Unfortunately, I’d never done GUI programming before and my experiment with the TKinter GUI framework didn’t quite work.

I was pretty busy programming at the start of 2021 across a few different languages. Let’s jump right in!

C#

I’m nearing the end of the GameDev.tv online RTS course, and it’s been a lot of fun. Since last time we added player colors to the units, a minimap that can be used to move around the screen, new units, and a Lobby UI. I’m a few lessons away from being able to create binaries I can use to play online with others or via Steam.

It’s been a pretty busy 2 weeks. I’ve basically either been finishing up end of year blog posts or programming. Let’s jump in!

Extra Life Donation Tracker

I have the 5.3 release of my Extra Life Donation Tracker. I had a few minor refactoring goals for that release, but also a few user-facing enhancements. I added in the ability to grab the user’s avatar as well as their team’s avatar. They can now use that as an input in either XSplit or OBS. During these two weeks I also fixed a user-reported bug on crashes if a donor had emoji in their name. Oh emoji, you’re the bane of my programming existence!

I last wrote about the software I’m using while programming back in March.  I think at the time I was thinking of writing quarterly updates, but my preferences didn’t change with that much regularity. I decided to make it one of my annual posts instead. So here is the software I used in 2020 to program.

Python Projects

PyCharm

For my Python projects I transitioned fully to PyCharm Community Edition. I documented my reasons for moving towards Pycharm in this post with a followup here. As I was writing this, I learned of a Real Python guide to Pycharm that taught me a few things I didn’t know about how to make better use of PyCharm. PyCharm has made Python programming a real joy. For any libraries I have imported (or standard libraries), it provides excellent code completion as well as context for function or method arguments that saves me time vs looking it up in documentation. The git integration is also great and I’ve recently started exploring usage of the lower git window which may make GitQlient obsolete for my Python projects. I haven’t made the best use of the debugger yet, but I’m slowly learning how to take advantage of it in my larger projects. If you’re a Python programmer I can’t imagine a better IDE. I did have access to Pycharm Professional for a while in 2020, but I wasn’t doing any Flask or Django work, so I didn’t really notice anything useful over the community edition.

Back in 2019, when I did my programming retrospective I made a few predictions. How did those go?

• Work on my Extra Life Donation Tracker? Yup! See below!
• Write more C++ thanks to Arduino? Not so much.
• C# thanks to Unity? Yes, but not in the way I thought. I only did minor work on my game, but I did start a new GameDev.tv class.
• Learning Ruby? Well, I wouldn’t necessarily say I learned Ruby. I did finish the book Ruby Wizardry and I took copious notes. But until I do some practice - maybe via some code katas, I don’t think I’ll have solidified it in my mind.
• 3D Game Dev? Nope, not really.
• Rust and Go? Not even close. Although I did make sure to get some books on the languages.

So, what happened? On the programming front, I wanted to continue my journey to truly master Python after having used it at a surface level for the past 15ish years. I dedicated myself to doing the Python Morsels challenges (more on that below) and working through various Python development exercises. Outside of programming, the time I had off from COVID was used to play with my kids and they wanted to play lots of video games. So we took advantage of having way more time than usual to do that. So a lot of my goals slipped. We’ll get to 2021 predictions at the end, so let’s take a look at 2020!

Recently I came across this video where a programmer solves the same problem in 6 different programming languages:

What’s incredibly beautiful are the Haskell and APL solutions. Whereas every other language requires multiple lines, Haskell solves the problem in just one line. And APL is just a few symbols.

Here’s the same guy solving a problem from the Leetcode challenge in a few languages. Once again, it’s pretty neat how the elegance of the solution varies across languages:

C#

Back when I was doing GameDev.Tv’s Unity 2D class, I really wanted to know how to do multiplayer games (I also wanted some better support on using Xbox/PS3 remotes in games). Well, this year they released their Multiplayer class. So, naturally, I bought it up. I started working on it, resulting in two Github Repos. In the first section we were learned the basics of the Mirror add-on. I’m currently working through the second section, where we will create a basic RTS. I haven’t reached a real differentiation point from the GameDev folks. That may come later after we get past the basics.

As you recall from the previous blog post, I’d installed Unity and JetBrains on my Fedora 32 computer via Flatpaks. I was going to use them for the Unity Multiplayer course I was taking on Udemy. Unfortunately it was an immediate fail and in lesson one after they have me install a new inputs library and restart Unity, it would always crash upon loading the file. I’m currently installing Unity 2020.1 on my Windows computer where I don’t expect to have that issue. Assuming I don’t, then it’s a big fat nope on using Unity on Fedora via Flatpak (at least for this class). Which, to be fair, is not on their supported OS list - which is only Ubuntu and CentOS 7. (And the latter for movie-making)

As I mentioned last year in my 2019 in Programming post, I created a bunch of 2D games in Unity by following along with the Gamedev.tv classes. I would watch the videos on Linux and jump over to my Windows computer for the programming, learning how to use SourceTree and Microsoft Video Studio in the process. But for some reason, going back and forth with the KVM when running Unity would sometimes freeze up the Windows computer. So when I saw someone on Fedora Planet running Unity Hub, I thought I’d see if there was a Flatpak - and there IS! Also, I’ve fallen in love with JetBrain’s Pycharm, so I thought I’d go ahead and use their game dev IDE, Rider. ( There’s a Flatpak for that, too!) So, let’s see how well this works!

I just found out today that PyGame 2.0 was released yesterday, on the 20th anniversary of the software. One of the first steps I took with Python was a series of games I made from tutorials in Linux Format Magazine. On Github I’ve got my shifter game and my Space Invaders clone. The shifter game is a little wonky since I haven’t touched the code in over a decade. But I was able to make the one shift needed to make the Space Invaders clone work on Python 3. So you can enjoy those and celebrate that PyGame development has picked up steam again.
