"To make a square, you just add another triangle, it's really hard to mess this up" *messes it up* I felt that. I did this first year of my apprenticeship as a software dev (germany, there is such a thing) when I was bored. Although back then I didn't use an engine, I tried going from very-scratch using LWJGL, ended up eventually bluescreening the PC because I never freed up any of the ressources I allocated :'D
the reason why the grass and leaves textures are gray is because Minecraft uses a foliage texture for biomes, and it makes it easier for Mojang to change the leaves and grass color based on biomes
Your rendering issue with transparent is that transparent objects shouldn't write to the depthmask, so Unity (wisely) enforces this. Meaning triangles may now render even if they're behind triangles closer to the camera. This is a well known issue. That's why Unity has the queue implementation for shaders. Rendering all opaque objects (with depth testing and masking) then rendering all transparent objects (with depth testing but WITHOUT depth masking) is the simplest and most common fix for that. If you would've made 2 different shaders (/materials) and implemented them properly, you wouldn't have had to create 2 mesh layers in C# yourself.
It's not super efficient to update an entire chunk every time you place/break a block. Also if it's on the corner it will need to update 3 chunks at once. When a block is broken, only the block itself and the six neighboring blocks need to be updated. You also can exclude the faces of the block that were already generated along its surface by marking contact with air cubes. This will make caves interior render even if the player isn't in them but Minecraft already does this. It's why cave outlines are visible when lag spikes. Have you already optimized with occlusion culling? Once the camera turns away, you can stop rendering everything outside the cone of vision. Something really extra you could try 😅 is LoD: a single texture for distant blocks and condense them into a single polygon with a simplified pattern of the blocks with shading. I don't know Java but you could append the textures of very distant blocks into a single map then add it like a horizontal skybox wall in that direction. Looking forward to this series!!
Clearly you are way smarter than me lol. LoD was one thing I was thinking about but I have no idea how to implement it. As for only changing the blocks that need to be changed, I was also thinking about that but that might be quite difficult. I'll look into it though. Thanks for the suggestions!
For generation of the leaves on trees, you can make a function in the `World` class which sets a block directly if the target chunk is loaded, or queues it to be set after the target chunk generates. Like ``` public void SetBlockQueued(long x, long y, long z, Block block) { Chunk chunk = GetChunkFor(x, z); if (chunk == null || !chunk.IsGenerated()) { QueuePlacementAfterGen(/* chunk coords */ x / 16, z / 16, x % 16, y, z % 16, block); } else { chunk.SetBlock(x % 16, y, z % 16, block); } } ```
Yeah that's kinda what I was thinking about doing but I wanted to find a more permanent solution and the problem with this one is that if I were to try to generate really big structures, it might be setting blocks inside of chunks that the player already did stuff in
@@wsalevan you could also do like a second generation pass where you place the structures after generation but before the player can do anything by doing the structure noise beyond the terrain generated or you could take a look at how minecraft does it
I got to the same point but now I'm making a system that is not as much hardcoded by using scriptable objects to store each block's appearance. Also blocks can be on the same location if authorized to.
@@wsalevan No I don't think so. But its more prown to modding in theory. I had mistakenly wrote "chunks" instead of blocks. But baking chunks could be potential frame saving if they can become low-res at high distance from the camera, or even static render on flat plane. But that sounds complicated to do.
Ohh the blocks. That makes more sense. Yeah you're right, that would increase modding capabilities quite a bit. I do have scriptable objects for blocks too, but then I convert it to a non-scriptable object block type. I do it this way to make it easier to add blocks because all I have to do now is put the textures in instead of having to find the coordinate positions in a tilemap. Though I could probably just make the resource loader work for rendering the blocks and put everything else in the scriptable objects. As for textures becoming low res, I'm not sure how much that would help since the textures are already only 16x16 but maybe I'm underestimating the performance boost because I never tried it. I think the biggest performance boost would be removing triangles from chunks when at a far distance, but I'm not sure how to determine what triangles to remove.
@@wsalevan My idea was to bake a render of the chunks at far distance into a flat texture wich would maybe be mapped on to a surface generated using a marching cube algorithm. This way your not trying to decide which triangle to remove but changing the way that blocks are added to the final mesh in such way that reduces polygon count. You could eventually use marching cube but instead of iteration through each blocks you can make an average of 8 blocks into bigger cubes. To be fast I've watched videos explained generations of procedural terrains using a compute shader. But its far beyond of what I'm currently working on. (Still at the stage of managing my code and organizing it so I'm happy with)
Could you please make a tutorial on how you actually use 3D Perlin Noise? I can't find good tutorials anywhere! My begging question is how you know a block underground should be air or something else!
To be honest, I didn't know how to use 3d noise so I just copied a 3d noise algorithm from the internet, but yeah I can make a tutorial about how to use it. To determine the block type of underground blocks, I use the 3d noise function and if it's below a certain value, the block will become air or whatever other block I set it to. Otherwise, it'll be solid. I hope this helps!
I'm gonna be sas and ask for the project source :> so I can create minecraft clone without the hard step of block and terrain generation. Anyway this looks great, u are smart
I'm glad you enjoyed it! As explained in the video, not all sides of each block are shown, and rendering those extra sides takes a lot of time. With Unity's built in cubes, we cannot remove faces from it, so they cause a lot of lag
@@wsalevan I'm sure it's not as inconsistent as my will to live 🤣- if it's any easier you could Livestream for a couple hours and stitch edits like a pro- (*cough* code bullet *cough*), nevertheless mental is vital to any progress. If you need a break, take one, even if it's a couple years, you'll come back with 10x, nah 1000x more spectacular things to share with us. Can't wait for part 2 🖤
Streaming does give more entertaining content but does make it harder to edit so I might do a mix of both like I did in this video. Thanks for the encouragement!
@@wsalevan post script- as despicable as they are, short form content has taken the world by storm, if a 10-30 min devlog is too much, maybe try 60sec progress updates 😁
You're able to create meshes in scripts and then create a shape with it. I'm doing that here because if I just used Unity's cubes, there would be a ton of extra faces being rendered that will slow the game down. I can remove those extra faces when I generate them in a script

Dude I got half way through the video before realizing that you only have 320 subs, I was convinced this was from a bigger channel. Keep it up :)
Thanks!
somewhere out there notch is like: "Hey I've seen this one! It's a classic!"
I like how you have gone from maze generator video tutorial into remaking Minecraft
Yup
being a programmer in a nutshell.
Yeah pretty much lol
I thank the TH-cam algorithm for allowing me to find this awesome channel, keep up the wicked work my guy!! you've got yourself another subscriber
Thanks!

Very underrated channel! Let’s get this guy to 1M quick
Thanks!
Nice video dude!! Thoroughly enjoyed it :D
Thanks! I'm glad you enjoyed it
Can't wait for the next part!!
underrated, much!?
It's so funny how similar some functions are from a drawing programm to Minecraft!
at the start i was like "wait why did he make a cube from scratch???" soon it made a load of sense
how do you not have more subs, this is awesome. keep up the work my guy👍
