Visual scripting tool for Roblox that generates real Lua code

BloxBlock is a browser-based visual scripting platform that helps users build Roblox game logic using blocks (similar to Scratch), while generating real Lua code that can be used directly in Roblox Studio.

Many beginners struggle with learning Roblox scripting due to:

• Lua syntax complexity
• Lack of understanding of game logic structure
• Over-reliance on copy-pasted scripts

BloxBlock aims to solve this by making logic visual, while still exposing the real Lua code behind it.

• 🧩 Visual scripting system powered by Blockly
• ⚡ Real-time Lua code generation
• 🔁 Bidirectional highlight (blocks ↔ generated code)
• 🎮 Pre-built game templates (Obby, Tycoon, Combat, Clicker)
• 💾 Cloud saving with Firebase
• 👤 User authentication system
• 🧩 Custom block creation system
• 🌐 Multi-language support (English / Spanish)

1. Open the editor
2. Drag and connect logic blocks
3. See Lua code generated in real time
4. Copy the code into Roblox Studio
5. Run your game instantly

Example flow:

Player joins → Give coins → Show message → Update stats

BloxBlock is not meant to replace coding.

It is designed to:

Help users understand how visual logic maps to real Lua scripting, making the transition to code easier and more intuitive.

• Frontend: HTML, CSS, JavaScript (Vanilla)
• Block engine: Blockly 10.4.3
• Code generation: Lua generator system
• Backend: Firebase Authentication
• Database: Firestore
• Hosting: Firebase Hosting
• Internationalization: Custom i18n system

• Event-based logic (PlayerAdded, Touched, ClickDetector, etc.)
• Variables with optional global scope (_G support for cross-event logic)
• Game mechanics modules (combat, economy, UI, world manipulation)

Includes working pre-built systems:

• 🎯 Obby (checkpoints, lava, platforms)
• 💰 Clicker (currency + multipliers)
• ⚔️ Combat Arena (weapons, damage zones, respawn system)
• 🏭 Tycoon (income, upgrades, rebirth system, saving/loading)

• Persistent saving using Firestore
• Auto-save on change, tab close, and intervals
• Project sharing with public links
