Mobs Using Spears Do Not Receive Correct 4.5 Block Attack Range Increase

Description:
The latest beta version 1.21.130.27 patch notes specifically state that spear attack range has been increased to 4.5 blocks and that this change should apply to both players and mobs. However, actual testing reveals that while players correctly benefit from the extended 4.5 block reach, mobs using spears remain limited to the original 2.5 block attack range. This creates a significant inconsistency between player and mob combat mechanics.

How to Reproduce:

1. Equip a zombie with an enchanted spear (preferably with Sharpness to visualize attack particles)

2. Place the zombie in a minecart to maintain fixed positioning

3. Position armor stands at varying distances (2.5-4.5 blocks) from the zombie

4. Observe attack particle effects to determine maximum effective range

Observed Result:

• Mobs only damage targets within approximately 2.5 blocks when using spears

• No damage occurs to targets between 2.5-4.5 blocks despite the announced range increase

• Attack particles only appear within the 2.5 block traditional melee range

• Player character testing confirms proper 4.5 block reach with identical spears

Expected Result:

• Both players and mobs should have consistent 4.5 block attack range when using spears

• Mobs should be able to damage targets at the extended ranges matching player capability

• The range increase should apply universally regardless of who wields the spear

Additional Notes:
This implementation inconsistency undermines combat balance and mob effectiveness with the new spear weapon. The discrepancy suggests that the range adjustment was only applied to player attack logic while missing the corresponding changes to mob combat AI and reach calculations.
