How can I make mineable terrain?

[Plott_1]

So, I’m making a survival game and I would like to be able to mine terrain. Example like 7DaysToDie or Valheim, something like that with using something like a pickaxe, where you can dig into the terrain and terraform.
I have tried looking around for something like this but haven’t been able to find anything.
Is there a special way you will have to make the terrain or does it not really matter.

I would really appreciate if anyone could atleast point me in a direction.

@Plott_ im afraid this is incredibly hard to do I tried to do this but couldn’t find anything when I first started game development but here’s a video that has a GitHub link for there project I hope this helps

I am also working on a game like 7DaysToDie. I am using Voxel Play from the Asset Store and heavily modifying it to suit my needs. This includes:

• writing a custom file serialization function to work with larger map sizes
• writing the functions for RequestVoxel, RequestChunk, BreakVoxel, and PlaceVoxel on both client and server (server authoritative)
• wrapper that connects the VoxelDefinition to my existing inventory system
• inventory hotbar system that allows for hotkeys
• tieing all the small features like the “block damage” effect into my own code
• writing a custom load/unload chunk system on client and sever that automatically requests all chunks around the player, and unloads them when unneeded

I think this would be impossible unless you are extremely organized and show good foresight in coding. Once you get a system this big, it can start breaking faster than you create it. I wrote all of my networking code myself, which took several years to complete, so I already knew exactly what to do after I bought Voxel Play.

The voxel system must be rendered directly on the GPU with no GameObjects. You will have to deal with shaders, camera frustrums, runtime collider mesh and navmesh generation, and many other obstacles. The code has to be extremely well optimized, which takes in-depth knowledge of advanced C# features.

Needless to say, it’s a huge system, and it might be easier not to reinvent the wheel and just get a package like Voxeland or Voxel Play. I’d recommend building up a knowledge of Unity and networking by fleshing out the rest of your game first if you haven’t already. Good luck!
