WebVN

A Visual Novel Engine for the modern web.

This pet project is envisioned to become a Visual Novel engine (like Ren'Py) and authoring tool to easily create and share web based Visual Novels.

Maybe I'll make a proper game with this some day...

Demo

Features:

• Editor with
  • Live preview
  • Jump to line
  • Live code validation
  • YAML-based scripting language
• Animated ADV text box with name tags
• Animated decision prompts
• Control flow with variables, arithmetic and boolean logic
• Sprites (translation)
• Backgrounds (panning, scaling)
• Background transitions
• Background music and sound effects
• Fast forwarding though seen text (skip mode)
• Unlimited "undo/rollback" history
• Saving/Loading (menus are WIP)
• Mobile friendly fullscreen mode

Technical feats:

• Redux-inspired immutable state management
• Rendering and UI code directly against browser DOM APIs, no frameworks or libraries involved. (Experiments with React & others still left in the repo)
• Seen text nodes stored using custom ConsecutiveIntegerSet data structure
• The "path" taken through the VN in the only thing persisted upon saving. Full state is simulated upon loading.
