SafeType

A memory protection system for games that prevents common cheating methods like memory scanning and value modification.

✨ Features

• Encryption: Values are XOR'ed with dynamic keys and bit rotation
• Tamper Detection: Runtime integrity verification with checksum validation
• Zero Friction: Replacement for standard types with implicit conversions
• Unity Integration: Fully serializable in Unity Inspector
• Optimized: Minimal overhead with lazy initialization

🚀 Usage

Unity

// Declaration
private SafeInt _score = new SafeInt(0);
private SafeFloat _health = new SafeFloat(100f);

// Use it like a normal int/float
_score = 100;
_score++;
_health -= 25.5f;

// Display in UI (implicit conversion)
textComponent.SetText($"Score: {_score}");
healthBar.fillAmount = _health / 100f;

// Serialize in Unity Inspector
[SerializeField] private SafeInt _playerLevel = new SafeInt(1);
[SerializeField] private SafeVector3 _spawnPoint = new SafeVector3(Vector3.zero);

📦 Supported Types

• SafeInt
• SafeFloat
• SafeDouble
• SafeVector2
• SafeVector3
• SafeQuaternion
• SafeBool

🛠️ Installation

1. Clone or download the repo
2. Copy scripts to your Unity project
3. Replace critical variables with Safe variant
4. Build and test!

⚠️ Important Notes

• Client side only - Never trust the client for server-authoritative games
• Defense in depth - Use alongside server validation and other anti-cheat measures
• Performance consideration - Suitable for critical values, not massive arrays

🎯 TODO

• Additional type support (custom structs)
• OnValueChanged events
• C++ / Unreal Engine port
• Network synchronization helpers
