How to Program Voxel Worlds Like Minecraft with C# in Unity

See this series on Udemy. There's a free little intro video that explains voxels better than I can in a reddit post, and one on why you can't use cubes. Also see the video name 'Anatomy of a cube'. If you're willing to spend $20, this should answer all your questions and help you build your project you want.

Not sure if serious question or just a meme, but my favorite Unity instructor on Udemy (Penny de Byl) has an 18 hour course on this subject: https://www.udemy.com/course/unityminecraft/

Full disclosure: I've taken many of her courses but not this one so I can't vouch for the course itself; just the teacher. I'm also not getting paid to pimp her courses but I wish I did because they're great.

Any tips with the basic block and chunk generation?

I've went through this course but the generation ends up. Being slow when trying to build anything but a small world.

If you're willing to pay a little there is a great tutorial course in Udemy about Minecraft type voxel world generation in Unity.

I actually purchased a class of of Udemy about this exact question - it's at https://www.udemy.com/course/unityminecraft/ and it's essentially a perlin noise distribution.

Along with some hardware peripheral you can gift him some course from udemy, based on his experience. Here are few suggestions 1: https://www.udemy.com/course/unityminecraft/ 2: https://www.udemy.com/course/unitycourse2/ 3: https://www.udemy.com/course/unitycourse/

Key an eye on pricing udemy courses are on promotion mostly where a course is sell under $20.
