Unpacking can degrade performance here?

about the pair?idk,it seems better than 2 hashmap for me

I think it's better to replace Pair<BlockState, Float> with this
public record BlockStateResistance(BlockState state, float resistance)private final HashMap<BlockPos, BlockStateResistance> map = new HashMap<>();There was a problem hiding this comment.
I tried,it look cleaner, but it crash at runtime, mixin seems to not really like that

Try to create a class in common package

profiling:not big improvement,like 2~3% of the explosion |
|
Caching the inner 3x3x3 or 5x5x5 might be a good idea. I think it is not viable to cache all blocks in the explosion range, as the outer ones will not be hit by many explosion rays, making the caching less effective. |

iirc it wasn't better, and more complex,but I will not be able to test in the next days |

cache all blockstates and blast resistance in a hashmap
Modify a lot the structure, and is probably not very clean
7.6s vs 13.1s in normal lithium:1000 tnt at 0 10 0
not very precise,I got many differents result,but it seems to be significantly faster
original idea to cache origin blocks in array by sarah
