[Any optimization for mc.player.world.getBlockState()?]

I am writing a pathfinding algorithm for my mod. It requires multiple using of mc.player.world.getBlockState(...)

Is there any way I can make a local in-moment copy of the world? (for using it instead of calling mc.player.world.getBlockState(...) all the times)

Thanks a lot.

[How to simulate mining in a Client-Side mod 1.16.5 Forge?]

Ok, Whatever. Honestly, my question is about THE functionality which doesnt work but not about "BOTS" or "CHEATS".
What I said is that simulating Left click pressing doesnt work, although simulating other buttons work well.

[How to simulate mining in a Client-Side mod 1.16.5 Forge?]

I am creating a bot for Minecrft. One of its functions is mining. Although I can simulate Moving, Jumping and Using Items, i cant simulate mining. I mean, I can simulate leftclicking even every tick, but when I set LeftClick to held nothing happens (and leftclicking with my mouse doesnt work also).

Do you know, how can I simulate continuous leftclicking (mining)?
