Another minecraft clone

Thank you! for the feedback.

I was going to say the lighting shouldn't make much of a difference but wow I didn't even realize, when I disable the lighting the fps on my PC went from 465fps -> 1312fps. So thanks for the heads up, I probably should have paid more attention to the lighting settings, haha.

As for the amount of objects, there isn't many. Each chunk (16x256x16 cubes) is its own node, containing arrays for its voxel values, ArrayMesh data and a generated mesh attached to it. This is fairly typical stuff for every voxel engine or minecraft clone.

When the player and game are sitting idle, other than lighting what takes up the performance is the amount of vertices being rendered, which is entirely dependent on the graphics card which is why your 2080 Ti handles it well. Smaller/larger view distances make the biggest difference here.

As for chunks being generated; GDScript is totally SAVED by multi-threading. It's an incredibly powerful feature of Godot, without it the game was terribly laggy even while doing "yield idle_frame". Thanks to multi-threading it doesn't matter what you throw at GDScript, it will still run the game smoothly. The thread will simply take a longer period of time to produce a result (the more you give it to do). I'm really happy I learnt how to do multi-threading from this experience.

This project does have a massive downside though, turn on "caves" option and the chunks will take just a little bit too long to generate in my opinion. This is not good enough so I accepted defeat here.

Thanks! The project's probably not very readable since in a few areas I prioritized optimization instead of making an open source project that could actually be useful to others.

I used a program called Megazeux for about 4 years when I was very young, then later switched to Game Maker, using it on and off for 8 years while taking a few year long breaks. I don't have much to show for it, Megazeux is ancient DOS ASCII stuff and I only completed a few Ludum Dare games in GM. The action RPG roguelite I've been working on in GM is still in development at about 95% completion but instead I've been neglecting it and screwing around with Godot for the past year. (someone kill me for not just finishing it)

The first thing I got working in Godot was this crummy drawing example, which helped me grasp classes and how to understand the help file.

Then I made this Dungeon Keeper Warped Walls project, which this Minecraft project stands upon. The cubes it places are blender models, so for the mincraft project I had to learn how to build a cube in Godot from scratch so I could do proper culling. This post by Zylann was the starting point, the first cube.

I truly wracked my brain working on this for 2 months (+ an extra month for polish), it was the most complicated thing I've done. Now that I've done it, it all seems fairly simple in hindsight, funny how that always goes. I've been working on figuring out how to do online multiplayer in Godot and I suspect the same thing is occurring with it being complicated but will probably soon enough turn out to be quite simple. If you want to be a better programmer you really need to just jump in the deep end, watching tutorials and searching forums/github/discord/helpfile/google etc. Learning has a backwards difficulty curve going from hard -> easy, so it's comforting to remember that every concept gets easier the more you expose yourself to it.
