The script editor has been rebuilt from the ground up into a **full-featured code editor** right inside Minecraft, with syntax highlighting, autocomplete, error detection, and support for writing scripts in Java.

## Script Editor
### Writing Code
- **Syntax Highlighting** - Keywords, types, variables, methods, strings, and comments are color-coded automatically. Local variables, global fields, and chained method calls each get their own color
- **Autocomplete** - Smart suggestions for methods, fields, and classes as you type. Knows whether you're in a static or instance context. Frequently used members appear first, and the cursor is placed between parentheses when a method has parameters
- **Auto Imports** - Type a class name and the editor suggests the correct import
- **Error Detection** - Catches mistakes before you run your script. Wrong argument types, missing methods, type mismatches, and unused imports are underlined with detailed error messages on hover
- **Built-in Globals** - Objects like `Math`, `JSON`, `Date`, and `Number` are recognized automatically in JavaScript mode. Script variables like `npc`, `world`, and `event` are also recognized
- **JS Language Support** - Arrow functions (`=>`), shorthand methods, object literals, and array expressions are all understood by the highlighter and type resolver
> Hover over any symbol to see its **full type information**, documentation, and declaration. Hover tooltips support JSDoc with markdown formatting, headings, code blocks, and scrolling for long documentation.

### Navigation
- **Go To Line** - `CTRL+G` jumps to any line
- **Search & Replace** - `CTRL+F` to search, `CTRL+H` to replace. All matches highlight in real-time
- **Go To Definition** - `CTRL+Click` any method, field, or type to jump to its definition
- **Fullscreen Mode** - Expand the editor to fill your entire game window
---
### Editing
- **Undo/Redo** - Smart undo that works on whole words, not individual characters
- **Duplicate Line** - `CTRL+D` to duplicate the current line
- **Comment Toggle** - `CTRL+/` to comment or uncomment selected lines
- **Rename** - Rename a variable or method and every occurrence updates at once
- **Move Lines** - Move lines up or down with shortcuts
- **Copy Whole Line** - Copy with nothing selected grabs the entire line
- **Triple Click** - Select an entire line instantly

### Visual Polish
- **Line Numbers** - Clean gutter with current line highlighting
- **Smooth Scrolling** - Eased scroll animations
- **Indent Guides** - Vertical lines showing nesting depth, with the current scope highlighted in green
- **Automatic Loading** - Any mod can include `.d.ts` definition files in their `assets/<modid>/api/` directory and they appear in the script editor automatically
