Create MINECRAFT in Unity - S3 - P4 Making our code multithreaded P2

In the Section 3 we will explore how easy it is to make our code for the procedural voxel world tutorial multithreaded when we have separated data creation from the rendering of the chunks.

Fantastic tutorials, really been enjoying it. Something I noticed with this is that once you move to the dictionaries to handle rendering, the ordering on SelectPositionsToCreate and SelectDataPositionsToCreate is pointless since a dictionary is not sorted. This will make the generation not prioritize rendering the chunks closest to the player first

Hi! Because the ProcessChunkColumn() function only modifies one column of the chunk and doesn't need data from other parts of the chunk it's perfectly safe to parallelize this part of the code. The C# System.Threading.Tasks library has a handy function for parallelizing for loops, the Parallel.For() function. I parallelized the outermost for loop (the x loop) using this and got an 3x speedup. However, parallelizing it further by doing the z loop in parallel as well unfortunately makes it slower due to the overhead of keeping track of the threads.

Would GPU instancing further improve the performance in this case? Having single draw calls would require the meshes to be the same, but they are not ofcourse.

Something that I thought would seem really interesting is having infinite height ^^

For some reason chunks are missing so there are just holes in the terrain

can you make a basebuilding game tutorial like rimworld
