Accessing data for multiple days from weather api

To see why this is important (for HttpClient specifically) look here (if interested): https://learn.microsoft.com/en-us/dotnet/fundamentals/runtime-libraries/system-net-http-httpclient#instancing

Accessing data for multiple days from weather api

This is as opposed to what (if I remember correctly) you had before:

class MyProgram
{
    async void FetchWeatherForecast()
    {
        using var client = new HttpClient(); // Not good!
    }
}

class MyProgram
{
    async void FetchWeatherForecast()
    {
        using var client = new HttpClient(); // Not good!
    }
}

Accessing data for multiple days from weather api

Well, regardless. You should be able to create an instance of HttpClient and save the reference to a field/property of the class you are working in. For example:

class MyProgram
{
    private readonly HttpClient client = new();

    async void FetchWeatherForecast()
    {
        // Use 'client' as many times as you need
    }
}

class MyProgram
{
    private readonly HttpClient client = new();

    async void FetchWeatherForecast()
    {
        // Use 'client' as many times as you need
    }
}

Physics

Have you read the documentation? https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.FixedUpdate.html

MonoBehaviour.FixedUpdate has the frequency of the physics system; it is called every fixed frame-rate frame. Compute Physics system calculations after FixedUpdate. 0.02 seconds (50 calls per second) is the default time between calls. Use Time.fixedDeltaTime to access this value.

This would seem to be what you want:

private void FixedUpdate()
{
    World.Step(Time.fixedDeltaTime, _settings.Multithreaded);
}

private void FixedUpdate()
{
    World.Step(Time.fixedDeltaTime, _settings.Multithreaded);
}

Accessing data for multiple days from weather api

Here are some additional pointers: 1. Move the API key out of your code entirely, load it from a local configuration file. Make sure that the configuration file is not tracked by a versioning system (so if you are using git, add it to .gitignore) 2. Don't initialize HttpClient repeatedly. This is especially bad with this type. 3. Always return early if you can (google "c# return early" if you don't know what I mean) 4. You were checking whether the HttpClient was null right after creating it (so it should never be null, the condition is useless) 5. Ideally you should replace JObject with something else 6. You forgot to dispose the object in response variable

private const string ApiKey = "..."; // TODO Load from configuration file instead, keeping this in code is a bad idea

private readonly HttpClient client = new();

async void FetchWeatherForecast()
{
    string city = Citysearch.Text;
    string url = $"https://api.openweathermap.org/data/2.5/forecast?lat={lat}&lon={lon}&appid={ApiKey}";
    
    try
    {
        using HttpResponseMessage response = await client.GetAsync(apiUrl);
        response.EnsureSuccessStatusCode();
        string content = await response.ReadAsStringAsync();
        if (content is null)
        {
            Console.WriteLine("Received no content from wheather API");
            return;
        }

        JObject weatherData = JObject.Parse(content);
        // Handle weather data
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error while fetching from weather API: {ex.Message}");
    }
}

Also remove the API key from your message and keep it private

You probably need to call a different API endpoint See the docs here https://openweathermap.org/api
