The Red Eye | Sharingan (REWORK)

Sharingan (NeoForge 1.21.1)
THE INCREDIBLE REWORK OF MY MOD that i made, have "same" as before: 1, 2, and 3 tomoe, Mangekyou (Itachi, Sasuke, Obito, and Shisui), and the Eternal Mangekyou.

J    Sharingan tab (eye in use, remove, split the eye, layout)
V    Toggle Sharingan on/off (glass-breaking sound. i will put the normal sharingan sound later)
B    Toggle Mangekyou on/off (putting the normal sharingan sound later too)
\ , Z, X, C    Abilities 1–4 (ability 4 is Susanoo) (idk if it is actually these keybinds but you can change in controls so, who cares xd)
Chakra
(at least 10% is required to activate it). pressing the button without having chakra pauses regeneration for 3 seconds.
   Stage        Chakra drain while sharingan is active    Max chakra    Duration with a full bar
1 tomoe                         2 per second                              240                          2 min
2 tomoe                        1.5 per second                            360                          4 min
3 tomoe                        1 per second                               360                          6 min
Mangekyou                   2 per second                              960                          8 min
Eternal                           2 per second                             1200                        10 min

(Players with Mangekyou drain 2 chakra per second even when it is turned off, as long as the Sharingan itself is on.) (will remove later, just for now, it was a test but i forgor)

Each Mangekyou ability consumes chakra (the amount is shown on the HUD) and also causes eye strain. Susanoo costs 100 chakra to activate and consumes more for as long as it remains active.
Side effects of low chakra (cumulative)
Chakra ≤ 40: hunger. ≤ 30: slowness. ≤ 20: nausea. ≤ 10: weakness. (for now)

Active Sharingan clears negative effects
With the Sharingan turned on (any tomoe stage), nausea, darkness, and blindness are removed. Nausea caused by low chakra (≤ 20) remains.

Uchiha Clan and awakening
Every player receives the Uchiha Clan Emblem upon entering the world for the first time. Right-click it to join the clan. Only members of the Uchiha Clan can awaken the Sharingan (30% chance after surviving a near-fatal hit), and awakening can happen only once per world: anyone who has had a Sharingan before, even if it was removed, can only get another through implantation. Without the clan: +50% cooldown and chakra cost, +25% eye strain.
Progression
1 > 2 tomoe: 150 XP. 2 > 3 tomoe: 250 XP. While the Sharingan is active: +10 XP per mob killed, XP from collected orbs, and +1 XP per second.
Mangekyou: with 3 tomoe, kill any tamed mob; the Mangekyou you receive is random (Itachi, Sasuke, Obito, or Shisui).
Eternal: with both intact eyes from Itachi's or Sasuke's Mangekyou, implant the other one's eye. The Eternal Mangekyou restores your vision while it is in your eyes (blindness returns if you remove it) (idk if i let this, but i will.) and does not accumulate eye strain. 

Removing, splitting, and implanting <3
Remove the Sharingan: the button in the J tab gives you the item in your hand at any stage. 1/2/3 tomoe become an item for that stage (XP is preserved). Mangekyou and Eternal Mangekyou are removed together with the 3-tomoe eye as a single item, leaving you without a Sharingan. Eye strain and blindness remain.
Split the eye: any Sharingan (1/2/3 tomoe, Mangekyou, Eternal) can be split. The removed eye is chosen at random, left or right, and becomes an item in your hand that you can give to another player. If you are using one eye: +50% cooldowns, -50% eye strain, no Susanoo (Susanoo requires both eyes), and only that eye appears on your face. Using the item for the missing eye (even if it is the same Sharingan) joins the two eyes together again.Implant: right-click the item. It replaces any Sharingan you currently have (the old one returns as an item). The recipient receives the same XP the previous owner had; players outside the Uchiha Clan also receive the penalties listed above.
Slowing down ticks (game tick rate)
While the Sharingan is active, the entire game runs at (20 - N) ticks per second, like `/tick rate`: 18 (1 tomoe), 17 (2 tomoe), 16 (3 tomoe), 15 (Mangekyou), and 14 (Eternal). This slows everything down, including you, and applies to the entire server (with multiple players, the highest N takes effect). When turned off, the rate returns to 20. Chakra consumption is adjusted, so the real-time duration does not change. (about multiplayer, it will be probrably a bit broken but, i think it will be playable)
J tab and layout
The tab shows the Sharingan currently in use: with the Sharingan on, it displays the tomoe eye (and indicates whether Mangekyou is unlocked); with Mangekyou on, it displays the Mangekyou; when turned off, the eye appears dark and is marked as (disabled).

The Layout button opens the editor: drag the eyes around on the face, change their size (using the slider or mouse wheel over the face), and drag the HUD panels (status/chakra and abilities). By default, abilities are in the bottom-right corner. The layout is saved in `config/sharingan-layout.properties`.

Face
The eyes appear on the player's face (visible to everyone in third person) while the Sharingan is active, using the design for the current stage. If the player has only one eye, only the left or right eye appears.

Abilities

Itachi: Tsukuyomi, Amaterasu, Karasu Bunshin.

Sasuke: Chidori Current, Enton: Kagutsuchi, Kirin.

Obito: Kamui Intangibility (without becoming invisible), Kamui Teleportation, Kamui Suction.

Shisui: Kotoamatsukami, Shunshin, Revealing Gaze.

Eternal: Tsukuyomi, Amaterasu, Kirin, and Perfect Susanoo.

Susanoo (key 4): requires both eyes.
Blindness (permanent)
Eye strain never decreases. On average, each ability adds about 1% (around 100 uses until blindness). At 100%, you are permanently blinded and the screen turns black; with the Sharingan active, the effect disappears and you can only see dark silhouettes. The Eternal Mangekyou restores your vision while it is in your eyes.

Test commands (OP)
`/sharingan stage <0-3>`, `/sharingan mangekyou <itachi|sasuke|obito|shisui|eterno>`, `/sharingan xp <n>`, `/sharingan chakra`, `/sharingan uchiha <true|false>`, `/sharingan blind`, `/sharingan cure`, `/sharingan reset` (allows awakening again).

Textures
The eyes and emblem come from the images in `tools/source` (converted by `tools/process_images.py`).
