PCore Networking (early alpha)

Unity package for monitoring internet availability and trusted UTC time with anti–time-tampering protection.

Designed for mobile & desktop games that need:

• reliable internet state
• protection against device time manipulation
• simple static API
• optional reactive bindings (UniRx / R3)
• UniTask-based async (no coroutines, no thread issues)

---

✨ Features

• 🌐 Internet availability check via configurable HTTP endpoint
• ⏱ Server-based UTC time synchronization (via HTTP Date header)
• 🛡 Protection against device time rewind / fast-forward
• 💤 Automatic pause & focus handling
• ⚡ UniTask-based (main-thread safe)
• 🔁 Optional reactive API:
  • UniRx (PCORE_NETWORK_UNIRX)
  • R3 (PCORE_NETWORK_R3)
• 📦 Unity Package Manager compatible (Git URL)

---

📦 Installation (Unity Package Manager)

Via Git (recommended)

https://github.com/pashara/PCoreNetworking-Unity/tree/dev/0.0.1

Or via Packages/manifest.json:

"com.pcore.networking": "https://github.com/pashara/PCoreNetworking-Unity/tree/dev/0.0.1",

---

🔧 Requirements

• Unity 2020.3+
• UniTask (Cysharp.Threading.Tasks)

Optional:

• UniRx (add PCORE_NETWORK_UNIRX in scripting define symbols)
• R3 (add PCORE_NETWORK_R3 in scripting define symbols)

Enable only one reactive define at a time.

🚀 Public API

// Internet
bool PNetworkState.InternetAvailable
IReactiveProperty<bool> PNetworkState.InternetAvailableRx  // <--- UniRX/R3
event Action<bool> PNetworkState.OnInternetStatusChanged
bool PNetworkState.HasEverChecked

// Time protection
bool PNetworkState.TimeProtected
IReactiveProperty<bool> PNetworkState.TimeProtectedRx // <--- UniRX/R3
event Action<bool> PNetworkState.OnTimeProtectedChanged
DateTime PNetworkState.UtcNow
DateTime PNetworkState.Now

⚙️ Configuration (Optional)

Create config asset:

Assets → PCore → Networking → Config

in the root of the Resources folder, for example

Assets/Resources/PNetworkStatusConfig.asset
### or ###
Assets/YourGamePart/Resources/PNetworkStatusConfig.asset

Config fields:

• PingUrl – endpoint for internet check (default: https://clients3.google.com/generate_204)
• SuccessResponse – expected response (HTTP code or body)
• SecondsBetweenChecks – polling interval
• TimeoutSeconds – request timeout
• DeviceTimeToleranceMinutes – allowed device/server time delta

---

🛡 Time Protection Logic

• Server UTC is taken from HTTP Date header
• Internal time is based on Time.realtimeSinceStartup
• Device clock changes do not affect protected time
• Protection resets on ApplicationPause(true)
• Protection restored after successful re-sync

If device time differs from server time by more than tolerance:

• device time is considered untrusted
• server-based time is still used

---

❗ Notes

• Designed for anti-cheat / offline reward / cooldown logic
• Not a replacement for NTP-level precision
• Server must return valid HTTP Date header
