About this project
What does Mace Optimizer add?
Mace Optimizer
Makes mace smashes feel more instant and responsive on the client side.
When you hit with a mace, Minecraft can sometimes feel delayed because the server has to confirm the real hit, smash, sound, and particles first.
Mace Optimizer helps by showing the mace smash feedback instantly on your client, making mace hits feel cleaner especially when you have ping.
Works across 1.21 - 1.21.11 in the same jar (1.21.X)
Requires:
What it does
Mace Optimizer predicts the mace smash feedback client side when you attack with a mace while falling.
This makes the smash sound and impact particles show faster instead of waiting for the server response to come back first.
The server still controls the real mace hit, real damage, cooldown, fall distance, knockback, and whether the smash actually happens.
This mod does not increase mace damage, does not give extra reach, does not bypass cooldowns, does not make you hit earlier, and does not change how the mace works server side.
It only makes the visual and sound feedback feel smoother while the server stays in control of what actually happens.
works simular to my other mods
Mace Optimizer also reduces duplicate smash sounds when the real server sound comes in after the predicted client side sound.
This helps keep the mace impact feeling fast without making the sound messy or doubled.
There is also server opt out support, so servers can disable Mace Optimizer if they do not want players using it on their server.
This mod is client side, but if a server opts out then the optimizer will turn itself off there.
if you want the opt out just make a ticket in the discord!
Mace Optimizer is only a visual responsiveness mod, so don't worry about it changing how mace combat actually works server side. Hits, damage, knockback, cooldowns, fall distance checks, and real mace behavior are still handled by the server like normal.
