auto aim: a magic tool

English

Added

• Lock part mode: the new lockPart setting moves the aim point from the hitbox centre (CENTER, the previous behaviour) to the entity's eye height (HEAD), with an adjustable headOffset of −0.3…+0.3 blocks.
• HEAD matches the headshot rule used by Timeless and Classics Zero (TaCZ): the hit point counts as a headshot when it lands within eye height ±0.25 blocks above the entity's feet, so aiming at eye height keeps the shot in the middle of that band.
• New key binding J: switches between body centre and head in-game and shows the active mode on the action bar. The same toggle is available in the config screen as a 锁定部位 row, together with a 头部微调 numeric row.
• headOffset is clamped inside the hitbox (0.05 blocks margin), so a large positive offset never aims above the target's head.

Changed

• The crosshair-based candidate selection now uses the same aim point as the auto-aim, so "what you point at" and "what gets locked" agree.
• Config screen row spacing is derived from the actual row count, and numeric fields accept a minus sign.

Fixed

• The mod description no longer shows mojibake in the mod list (gradle.properties is parsed as ISO-8859-1, so the text now uses \uXXXX escapes).

Notes

• Configurations from 1.0.0 keep working: lockPart defaults to CENTER, so nothing changes until you switch it.
• The head point is plain coordinate math — no TaCZ API is used, so it also works with other gun mods and with vanilla bows/crossbows.

新增

• 锁定部位（头部锁定）模式：新增配置项 lockPart，把瞄准点从碰撞箱中点（CENTER，原行为）改为头部（HEAD，眼睛高度），并可用 headOffset 在 −0.3~+0.3 格范围内上下微调。
• HEAD 与永恒枪械工坊：零（TaCZ）的爆头判定一致：命中点离脚底高度落在眼睛高度 ±0.25 格内即判爆头，瞄准眼睛高度正好落在判定带中心，上下余量最大。
• 新增可改键的 J 键：游戏内直接切换「身体中心 / 头部」，准星下方提示当前模式；配置界面同时新增「锁定部位」按钮行与「头部微调」输入行。
• headOffset 会被收进碰撞箱内部（留 0.05 格边距），正微调调到最大也不会瞄到头顶之外。

变更

• 准星锁定选取改为与自动瞄准使用同一个瞄准点，做到「瞄到的」就是「锁到的」。
• 配置界面行距改为按实际行数计算；数值输入框允许负号。

修复

• 模组列表里的中文描述不再乱码（gradle.properties 按 ISO-8859-1 解析，改为 \uXXXX 转义）。

说明

• 1.0.0 的旧配置可直接沿用：lockPart 默认 CENTER，不切换时行为与旧版完全一致。
• 头部瞄准点只是坐标运算，不依赖 TaCZ 的任何 API，所以对其他枪械模组、对原版弓/弩同样生效。
