Efficient Hashing Mod changes the math used for block positions in the game. It brings a new system that stops block hashes from mixing up. This helps the game run better when checking where blocks are located.
Features:
- Zero Hash Collisions: It gives every block position a completely unique number.
- Fixes Vanilla Errors: The normal game mixes up 93% of block numbers.
- Uses PhiMix Math: It brings a new way to calculate block positions.
- Vanilla Compatibility: The starting block position still equals zero.
- Performance Trade-off: It runs slightly slower but stops big math errors.
