Common Stat

Common Stat – The Complete Stat & Formula Framework for Unity

Accelerate game development with a comprehensive, designer-friendly stat management system that scales from prototype to production.

Common Stat provides a robust, performance-optimized framework for managing game statistics, formulas, and dynamic calculations. Whether you're developing RPGs, action games, or complex simulation titles, this system delivers the flexibility and reliability your project demands.

Core Features

Flexible Attribute System

• Create and modify any game attribute (HP, Armor, Damage, Critical Rate, etc.) through intuitive ScriptableObject workflows
• Version-control friendly architecture with prefab-safe data storage
• Clone and customize attributes in seconds without code modification

Advanced Runtime Management

• Current/Max value pairs with automatic UI integration
• Live value updates with built-in serialization.
• Inspired by industry-leading titles like Elden Ring and World of Warcraft

Professional Development Tools

• Stat Visualizer Window: Real-time monitoring of current values, overrides, and calculated results
• Dedicated Stat Editor: Streamlined interface for rapid iteration and balance testing
• Live Validation: Catch configuration errors before runtime
• Comprehensive tooltips and contextual help throughout

High-Performance Formula Engine

Execute complex mathematical operations with zero garbage collection:

pow(${Armor} - 1, 2 + 1) + sqrt(${HP}) * abs(sin(${HP}))

+ max(random(1, ${Armor}), min(${HP}, 100))

+ dice(${Armor}, 6) * chance(${Armor})

Performance Metrics: 1000 formula evaluations in 0.006ms

Supported Operations:

• Basic arithmetic: +, -, *, /, %
• Advanced functions: pow, sqrt, sin, cos, random, min, max, dice, chance
• Variable references: ${stat_name} for dynamic stat values
• Runtime parameters: @{parameter} for contextual data injection

Technical Specifications:

• Zero-GC execution with thread-safe stack pooling
• Fully extensible function library
• Multithreading support for high-performance scenarios

Designer-Developer Collaboration

For Designers:

• Visual formula editor with live preview
• No-code balance iteration and testing
• Immediate feedback on statistical changes
• Intuitive drag-and-drop workflow

For Developers:

• Clean, well-documented C# codebase
• Strongly-typed, unit-testable architecture
• Comprehensive inline documentation
• Straightforward integration and customization APIs

Production-Ready Features

• Network Synchronization: Easy Stat or Value Synchronization
• Save System Integration: Seamless serialization for game state persistence
• Performance Optimization: Enterprise-grade efficiency for large-scale projects
• Extensibility: Modular design supports custom functionality without core modifications

Getting Started

The package includes:

• Complete demo scene with interactive examples
• WebGL build for immediate testing
• Step-by-step integration guide
• Performance profiling tools
• Comprehensive documentation

Use Cases

Perfect for projects requiring:

• Complex RPG stat systems
• Dynamic damage calculations
• Real-time balance adjustments
• Multiplayer stat synchronization
• Data-driven game design workflows

Common Stat transforms stat management from a development bottleneck into a competitive advantage, enabling your team to focus on gameplay innovation rather than infrastructure maintenance.

Build better games faster. Focus on fun, not stat system complexity.

This is the free edition. It does not include the Formula system or the advanced Editor panel, and it will no longer receive updates. For professional support, please use the CommonStatPro.
