Spear hit detection is inconsistent

Description:
I noticed some inconsistencies with the newly added spear in Minecraft:

• Missed hits: Sometimes, even when aiming directly at the target, the attack does not register, and the spear swings without hitting.

• Hitbox head issue: Hits are mostly detected only on the body, and do not register properly when aiming at the target’s head.

• Range issue while moving forward: When the player is running or moving quickly and keeps the spear straight, it can hit targets beyond the normal melee range. This makes the gameplay feel unnatural.

Expected Behavior:

• The spear’s hitbox detection should be more consistent, similar to swords or axes.

• Movement speed (walking/running) should not artificially extend the melee attack range.

Additional Notes:
This issue has a noticeable impact in PvP and makes the spear feel unbalanced.

I could not attach a video due to upload issues, but I can provide one via email if necessary.
