Pathfinding and environmental awareness

We’ve produced a very short devlog about the pathfinding / environmental awareness part of the AI development process for Virtual Warfighter. It describes how we’ve solved the problem of allowing AI soldiers to make different pathfinding choices, more intelligent than just take the shortest path.

We will probably expand upon this in the future by describing more, such as how to make the AI avoid exposed routes in favor of more concealed ones, if possible.

All this is part of the work being done for our upcoming coop game mode.


Mini test suite for async CQS backend

Our backend consists of a WebApi backend sporting an async CQS API (Not involving Event sourcing). I wanted a fluent syntax setup for our scenario tests, here is an actual example from the resulting code. (Code removed that are customer specific)

public class When_doing_a_complete_booking : BusinessTest
	private Booking _result;
	private DateTime _date;

	public void Context()
		Guid bookingKey = Guid.Empty;
		_date = DateTime.Now.AddDays(5);

		_result = Given(db => /* Setup here */)
			.When(() => new SearchQuery{ Date = _date, ...})
			.And(result =>
				bookingKey = result.First().BookingKey;
				return new ReserveCommand { BookingKey = bookingKey, ... };
			.And(() => new ConfirmCommand
				BookingKey = bookingKey, 
			.Then(db => db.Set<Booking>().FirstOrDefaultAsync(b => b.BookingKey == bookingKey));
