Chunk Update Progress (new prebuild available)

tl;dr new prerelease available with saving and loading for your worlds

Hello all,

0.4 is turning out really well, and while it doesn't really change the gameplay much it's a huge update for Boom.

Since the first prerelease for the update I've been working on speeding up the chunk generation and adding saving/loading functionality. Since the last prerelease I've multithreaded world gen and that of course sped it up a lot. I also just sped up some of the other things with chunks so loading new chunks should feel smooth.

I added saving and loading after this and it's pretty good but loading a lot of pre-saved chunks can cause more noticeable lag at the moment. I had to fix many different crashes and freezes but I think everything should be good now.

Before I release the final version I want to let the player name their saved worlds, delete them, and see how large they are. I also plan on adding a new world customization menu (choose seed and some preset settings for flat world vs hilly vs spiky vs fully random).

Let me know of any issues you have with the prerelease. Thanks for reading.
