Wow, and I thought Unity was bad... the main reason I was open to actually switching to Godot right at the beginning of this jam was because the Unity 2018.2 release on Linux is unusable, and because VS Code in Windows is inexplicably stupid compared to its Linux release, which is really, really good.
Now... I don't know. I'm finding myself absolutely hating GDScript, which is a sad excuse for a scripting language, and people are absolutely right about the state of documentation for Godot. It's abysmal. And the node types... just... ugh. They seem really great! Seem. Trying to actually get them to work as advertised, though? Think a ScrollContainer should be a container that scrolls with its contents? It seems to think so, too, but it's idiotically difficult to get that to work. And it seems not to allow removal of the scroll bar... or to support mouse click-and-drag... in many or most common scenarios.
I think I'm going to see if I can implement that behavior in a reasonable amount of time using signals, but if not... screw it. I'll just go back to a version of Unity that works for more than five minutes at a time in Linux and give up on actual pixel perfection.
