Luau Language Mastery (Index)

Luau语言精通（索引）

This skill has been split into three focused skills for better context efficiency. Load the one that matches your task:

为提升上下文效率，本技能已拆分为三个专注型技能。加载与你的任务匹配的技能即可：

Routing

路由

Task	Load
Syntax, tables, control flow, string patterns, math, idioms, scope, closures, sharp edges, JS→Luau porting	`roblox-luau-core`
Type annotations, generics, narrowing, inference, strictness modes, exports, sealed/unsealed tables	`roblox-luau-types`
OOP (metatables, inheritance), async (Promises, pcall, coroutines), module structure, service pattern, Roblox idioms (Instance creation, events, task library)	`roblox-luau-patterns`

任务	加载项
语法、表、控制流、字符串模式、数学运算、惯用写法、作用域、闭包、注意事项、JS→Luau移植	`roblox-luau-core`
类型注解、泛型、类型收窄、类型推断、严格模式、导出、密封/非密封表	`roblox-luau-types`
面向对象编程（元表、继承）、异步编程（Promises、pcall、协程）、模块结构、服务模式、Roblox惯用写法（实例创建、事件、任务库）	`roblox-luau-patterns`

Key Rules (always apply)

核心规则（始终适用）

Luau is NOT Lua 5.1. Has: generics,
```
continue
```
,
```
+=
```
, string interpolation (backticks), floor division
```
//
```
Arrays are 1-based.
```
#tbl
```
for length. Generalized iteration:
```
for k, v in tbl do
```
Always use
```
task.wait/spawn/delay
```
(never deprecated
```
wait/spawn/delay
```
)
Instance.new: configure properties THEN set Parent last (replication race)
Services:
```
game:GetService("Name")
```
at top of script, stored in locals
Methods: use
```
:
```
(implicit self) for instance methods,
```
.
```
for constructors/static
Prefer backtick interpolation over
```
..
```
concatenation
Local function order: callees above callers (no hoisting)
Only
```
nil
```
and
```
false
```
are falsy

Luau 不是 Lua 5.1。新增特性：泛型、
```
continue
```
、
```
+=
```
、字符串插值（反引号）、地板除法
```
//
```
数组以1为起始索引。使用
```
#tbl
```
获取长度。通用迭代写法：
```
for k, v in tbl do
```
始终使用
```
task.wait/spawn/delay
```
（绝不要使用已废弃的
```
wait/spawn/delay
```
）
Instance.new：先配置属性，最后设置Parent（避免复制竞争）
服务：在脚本顶部使用
```
game:GetService("Name")
```
，并存储在局部变量中
方法：实例方法使用
```
:
```
（隐式self），构造函数/静态方法使用
```
.
```
优先使用反引号插值，而非
```
..
```
拼接
局部函数顺序：被调用函数放在调用函数上方（无变量提升）
仅
```
nil
```
和
```
false
```
为假值
