The first comprehensive VS Code extension built specifically for RPG Maker MV plugin developers. 14 free features + 17 Pro features covering annotation intelligence, testplay debugging, conflict detection, TypeScript workflow, and more.
Stop writing MV plugins like it's 2010. Get syntax highlighting, validation, IntelliSense, and a full debugging workflow — all purpose-built for MV's plugin annotation system.
RPG Maker MV plugin development has had almost zero dedicated tooling. Existing extensions are either abandoned or provide just snippets. This extension gives you a complete development environment:
- Write faster — annotation completion, @type suggestions, plugin templates
- Catch bugs early — real-time validation, conflict detection, asset checking
- Debug without pain — one-click debugger setup, variable editing, live game preview
- Understand your project — dependency graph, class hierarchy, database browser
Free Features (14)
Annotation Intelligence
| Feature |
Description |
| Syntax Highlighting |
Color-coded /*:, /*:ja, /*~struct~ blocks — scope tags, type tags, dependency tags, and metadata each get distinct colors |
| Smart Tag Completion |
Context-aware @tag completion. In @param scope: @text, @desc, @type, @min, etc. Top level: @param, @command, @base, etc. |
| @type Completion |
All 24+ MV type values (string, actor, struct<>, switch[], etc.) with descriptions |
| Validation |
Catches typos (@commnd), invalid types (@type numbre), scope violations (@min inside @command), missing @plugindesc |
| Hover Documentation |
Hover any @tag or @type to see what it does |
| Formatter |
Reorder tags in canonical order within annotation blocks |
| Color Provider |
Inline color picker for hex colors in @default tags |
| Feature |
Description |
| Plugin Conflict Detection |
Static analysis detects multiple plugins overriding the same prototype method. CodeLens warnings inline. |
| Asset Reference Checker |
Validates @dir and @require tags against project files. Finds missing assets. |
| IntelliSense Setup |
One-click jsconfig.json generation for $gameParty, Window_Base, etc. autocompletion |
| Plugin Template Generator |
Scaffold a new plugin with correct annotation block and boilerplate code |
| Quick Actions Panel |
All commands organized in a sidebar panel |

Activate with a Gumroad license key. No subscription. Works offline.
TypeScript Workflow (NEW in v1.1.0)
| Feature |
Description |
| TypeScript Setup |
One-click setup: generates tsconfig.json, ts/plugins/, and copies RMMV type definitions (~72 classes, 250+ interfaces) for full IntelliSense on $gameParty, Window_Base, Scene_Map, etc. |
| TypeScript Auto-Build |
File watcher compiles ts/plugins/*.ts → js/plugins/*.js on save. Status bar shows build state. Errors appear in Problems panel. Cleans up .js/.js.map when .ts files are deleted. |
| TypeScript Templates & Snippets |
Plugin template wizard supports TypeScript output. 5 TS-specific snippets (rmmz-alias with this: type, rmmz-command, rmmz-plugin, etc.). Debugger setup includes source map support for .ts breakpoints. |
Testplay & Debugging
| Feature |
Description |
| Debugger Setup |
One-click launch.json using VS Code's built-in JS debugger. F5 to launch, breakpoints, step execution, variable editing in Variables panel. Auto-repairs debug port. |
| Quick Scene Reload |
Save your plugin → current scene reloads with fresh code. No restart from title screen. |
| Live Game Preview |
Real-time game screenshot in a VS Code webview panel |
| Testplay Console |
Captures console.log/warn/error from the running game into VS Code |
| Game State Inspector |
Live sidebar showing map, party, gold, switches, variables with auto-refresh |
Code Analysis & Refactoring
| Feature |
Description |
| Annotation Preview |
Live webview showing how your plugin appears in RPG Maker's Plugin Manager |
| Dependency Graph |
Interactive visualization of @base/@orderAfter/@orderBefore. Detects circular dependencies. |
| Parameter Rename |
Rename @param/@arg tags — updates @parent references and parameters["name"] in code |
| Multi-Language Sync |
Checks /*: and /*:ja blocks match structurally. CodeLens warnings for mismatches. |
Data & Project
| Feature |
Description |
| Data Hover (Pro) |
Hover $dataActors[3] → actor name/stats. Hover $gameVariables.value(5) → variable name. |
| Formula Evaluator |
Hover damage/healing formulas → see evaluated results inline |
| Note Tag Editor |
Visual WYSIWYG editor for note tags in actors, classes, items, enemies |
| Class Hierarchy |
Searchable tree of RMMV class inheritance — Scenes, Windows, Sprites, Game objects |
| Plugin Registry |
Check for plugin updates and view compatibility info |
Releasing Your Game
Important: Before distributing your game, run RMMV: Prepare for Release from the Command Palette (or the sidebar). This removes the debug port (--remote-debugging-port) from package.json so your released game doesn't expose a debugging endpoint to players.
