Collector3D! My First Ever 3D Game, Programmed in Godot!


Well, I finished the online YouTube tutorial by BornCG, which you can check out here. His tutorial is great and I learned a lot. I did make several changes along the way, and I used this as an opportunity to practice my work in Blender, making my own graphics for everything, as opposed to using the material he presented.

Code wise, it is the same game, but I did code several things differently, as I worked on expanding my knowledge of programming. An example would be the player ball rotation. In the tutorial, he shows how to use a variable and a set number to change the degrees to radii of the ball when it rotates.

However, This had several drawbacks. The first was that you needed to fiddle with it in relation to the variable of the ball’s speed. In other words, if you changed the speed of the ball, you would need to watch it move and guesstimate the change needed to the variable for rotation. Secondly, if you use his method, then when you stop pressing the arrow keys to move the ball, the ball stops rotating, but still “slides” until it comes to a stop.

To fix this, I changed the rendering of the ball rotation to be based off of vector speed. This makes the ball look very natural when it rolls. E.g., if it rolls forward, the degrees of roll looks naturally like the distance it is rolling over, and gives it a more realistic look. This also allows me to change the ball speed without having to adjust it’s degrees of roll. The best part, though, is when you release the arrow keys, and the ball is slowing to a stop, it now rolls, in accordance with it’s speed, slowing it’s roll as it slows to a halt in speed. It just look much more realistic.

I do believe that the author, BornCG knows how to do all this, and was just making a simpler tutorial for the viewers to follow. Or perhaps more specifically was trying to show the relationships of variables to those new to programming.

Other examples were just style points, adding timers and effects when you “die”, rather than the simple “cut to end screen” approach, and other such small things. Overall, the game mechanics and idea came from BornCG’s great tutorial. For a free resource that is widely available, I’d say this tutorial was a 5 star product, and I highly recommend it for anyone looking to start using Godot. I found numerous 2D tutorials for Godot on YouTube, but this is one of the very few 3D tutorials for Godot. Certainly worthy of your time if you are looking to start using Godot.

That said, here are some great links for my game:

* Notes: I did not try the Windows executable, since I didn’t have a Windows machine to test it on. I did try out the Linux executable on two different Ubuntu machines (17 and 18). If you try the Linux executable, be sure to chmod a+x the file so you can run it. Also, if you try out any of the executable files, be sure to comment below how well they worked and what OS you tried them on!

Is it “Go-Dot” or “Guh-Doe”?


Since I decided to go with Godot, I’ve really, really been enjoying the experience. Of course it is a tremendous help to learn how to use it while making a game and following a great tutorial by BornCG on YouTube. This guy is a really great teacher! So if you are looking to learn how to use Godot, be sure to check his tutorials out! By the way, according to BornCG, it’s pronounced “Guh-Doe”.


This is a slight detour from my intended project, but I like to have a successful path forward where I start using a new tool or programming language by using some sort of guide or tutorial. I find it helpful in making sure my environment is set up properly, especially if I get the same results as the instructor. So far, his tutorial is a pac-man/sonic like game where your sphere picks up coins and avoids enemies. I’ll try to include my final result when I get done!

So far, we have not used any native code, which you can program in yourself, using c++ or other languages. We’ve only been using GDScript thus far, which is an open source Python like language that is pretty simple to grasp. I look forward to seeing how we implement that, but either way, I’m certainly having fun!

Chirp – programming a HAM radio

While this tool isn’t new for most HAM’s, it was new for me. It’s called CHIRP, and it is a programmer for your radio. More or less, it allows you to input channels, change settings, and download/upload content to your radio. All of these functions can be done from the radio head itself, but this allows you to do it in a nice python scripted interface.

Of note, however, is that the Ubuntu and Debian repositories have incredibly old versions of the program. So old, in fact, that it could not read the downloaded information from the RepeaterBook query that I ran.

If you run into the same issue, be sure to check out chirp’s website: with this great explanation of how you can add the PPA to your sources list and get the latest version, like so:

sudo apt-add-repository ppa:dansmith/chirp-snapshots
sudo apt-get update
sudo apt-get install chirp-daily

I will mention, if you already installed chirp from the main repository, you will need to remove it first before installing this chirp-daily package. Once I did that, it was smooth sailing!

As for how to use chirp, I learned it all from a Youtube video by David Casler. It’s a great video and very thorough.

Fool’s Mate Friday!

Occasionally, I do a theme, or idea, on a given day for a period of time. Currently, I have been spending quite a bit of time working on chess engines and their play. So, I am going to create a “Fool’s Mate Friday” post. That’s right, every Friday, I’ll be bringing some small tidbit about programming chess engines, or chess games, or chess play in general. So, stay tuned for Fool’s Mate Friday!

This does bring up two important questions, though:

#1. What is a fool’s mate? Well, a fool’s mate is technically a check mate that happens in 2 moves. However, by extension, it can be used to refer to any set of opening moves that lead you to a checkmate very early in the game. Typically, it is specifically a reference to being checkmated by making poor moves on the fool’s part, rather than tactful moves on the winner’s part.


Technically, this would require 3 moves, and is thus a fool’s mate by extension, rather than by definition. 1. e3 f6 2. Qe2 g5 3. Qh5#.

#2. Why name it “Fool’s Mate Friday”? Two reasons, really. I needed a chess related term that started with F, and this is fairly accurate, as I am an unrated player of low standing (and understanding) in the game of chess, and my programming skills are not that good yet. Both of these lead me to make many mistakes, both in the game and in the programming thereof, which is certainly on par with the fool’s mate.
