201C: Async Operations
"Loading a heavy cargo container shouldn't stop the pilot from flying the plane. If your game freezes every time it saves a file or loads a leaderboard, you've created "Main Thread Blockage." A skilled Architect audits for Async/Await."
The Concept: Async & Await
**Async/Await** is the modern C# standard for handling long-running tasks (like File I/O or Web Requests) without freezing the game.
* **Task:** Represents an operation that will complete in the future.
* **await:** Tells the code "Go do this in the background, and come back here when you're done."
* **Task:** Represents an operation that will complete in the future.
* **await:** Tells the code "Go do this in the background, and come back here when you're done."
Red Flag Detected
The AI Trap: "The Main Thread Blocker"
You ask the AI: "Load the heavy map data from the disk."
// AI-Generated Code: The Lag Spike
void Start() {
// Audit Fail: Reading a 100MB file synchronously
// will freeze the game for several seconds.
var data = File.ReadAllBytes("Map.dat");
Process(data);
}
This is "IO Blocking." The CPU stops rendering the game to read the hard drive. Players perceive this as a massive lag spike.
Elite Telemetry
Research shows "Elite" teams achieve 15% faster lead times by keeping AI on a "very tight leash."
- Small Batches Solving one problem at a time prevents logic drift.
- Modular Design Localizing the "blast radius" of AI changes.
- Tight Loops Rapid iteration with constant code review.
The Architect's Correction
Corrective Protocol
// Corrected: Silk Smooth Loading
async void LoadMap() {
// The game keeps running smoothly while the disk spins
var data = await File.ReadAllBytesAsync("Map.dat");
Process(data);
}
Your Pilot Command
> A skilled Architect directs the AI to go Async. You command: "Use `File.ReadAllBytesAsync` and `await` to load the data on a background thread."
