Apologies in advance for the OT response:
That project was completely lost when the laptop I WAS using crashed yet again, and just happened to do so while I was in the middle of fixing my backup scripts, i.e., I didn't have any backups that were any good. I did do a backup from the linux mint boot disk (a flash drive), and cpio SAID it was writing files on the other flash drive. But when I rebooted, that drive was empty. The sad thing about that is, I KNOW BETTER than to create a backup without using either CRC32 and/or MD5 to verify every single file on the backup vs the original. In other words, I screwed up.
I'm no longer using GDevelop 5 anymore, either. I'm using Godot 3.2.2 on my new gaming/gamedev laptop (Lenovo IdeaPad L340-17IRH Gaming with Nvidia 4G GeForce GTX 1650).
Current (second first game) project is a 3D FPS. It starts with a made-up planet, Epsilon Eridani (a VERY popular system for Sci-Fi, e.g., Babylon 5's Epsilon 3) Epsilon Eri 4. You see the following (or similar) text being typed in front of a planet:
This is Epsilon Eri 4
It is home to a colony of over 200,000 human
women and children.
[about a 3 second pause]
It is about to be attacked
[Missile approaches planet, fired from behind the camera]
[Planet goes from blue/green to grey to bright white, then nothing but stars]
IT'S PAYBACK TIME.
The mission for the player is to successfully infil what Earth Intelligence has determined to be the attacking aliens' main command and control site for the Epsilon system and, by placing explosives on the power plant, a "quantum reactor", destroy the site. To succeed, player must make a successful exfil from the planet and witness the explosion from space, returning with complete Bomb Damage Assessment (BDA).
I was in the shower, and saw the entire story, and a few of several future side-missions, in a few seconds as it just flashed across my brain.
Godot 3.2.2 makes a 3D game like this almost as simple as a 2D platformer....almost.
And there are awesome tutorials on YouTube (and, while they are a minority, unlike those for GD5, there are still a few useless ones that are nothing but music videos), unfortunately).
