✅ Rocket Launch Console game

Hi, I am working on a mac laptop and only just starting out on C#, Took some courses and one of our homework assignments is making this Apollo Rocket Launch app. And at first vsc says it's proper code, but after waiting after 30 seconds it becomes a bombardment of red squiglies. I can provide screenshots if need be but I am just curious of what is the cause of it. I am not getting any proper results from googling, which I also guess is a bit of skill issue. pls halp. How do I shot web?

I managed to write the following code

static void Main(string[] args)
{
    // Initial values
    double h = 50, v = 8, mF = 35;

    // Preparation
    bool malfunction = false;

    // Repeating individual landing steps
    while (h >= 0)
    {
        // Displaying current values
        string height   = "Height: " + h.ToString("N1");
        string velocity = "Velocity: " + v.ToString("N1");
        string fuel     = "Fuel: " + mF.ToString("N1");
        Console.WriteLine(height + "  " + velocity + "  " + fuel);

        // Input
        Console.Write("Enter percentage of breaking (0-100): ");
        string input = Console.ReadLine();
        double percents = 0;
        try
        {
            percents = Convert.ToDouble(input);
            if (percents < 0 || percents > 100)
            {
                malfunction = true;
            }
        }
        catch (Exception)
        {
            malfunction = true;
        }

        if (malfunction)
        {
        percents = 0;
            Console.WriteLine("CONTROL MALFUNCTION!");
        }
        
        // Fuel check
        if (mF <= 0)
        {
        percents = 0;
            Console.WriteLine("NO FUEL!");
        }
        // Calculating new values
        double F = 360 * percents;
        double a = 1.62 - F / 8000;
        h -= v + a / 2;
        v += a;
        mF -= F / 3000;
        if (mF <= 0)
        {
        mF = 0; }
        // Output of an empty line
        Console.WriteLine();
    }
    
    // End of a single landing step
    // Output
    Console.WriteLine("Landing velocity: " + v.ToString("N1"));

    string evaluation = v < 4 ?
        "Soft landing, congratulations!" :
        (v <= 8 ? "Hard landing." : "Houston, crew is lost...");

    Console.WriteLine(evaluation);
    // Waiting for Enter
    Console.ReadLine();
}

static void Main(string[] args)
{
    // Initial values
    double h = 50, v = 8, mF = 35;

    bool malfunction = false;

this is the squigly mess

🥚FooYoungDevelopmentOP•13mo ago

litterally 1:1 the same code.

What VSC extensions are you using for C#?

🥚FooYoungDevelopmentOP•13mo ago

these doohickeys.

Pobiega•13mo ago

Hm, no devkit?

🥚FooYoungDevelopmentOP•13mo ago

I guess not, no

Pobiega•13mo ago

https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csdevkit

C# Dev Kit - Visual Studio Marketplace

Extension for Visual Studio Code - Official C# extension from Microsoft

Pobiega•13mo ago

this is the microsoft recommended extension the other one is iirc deprecated https://code.visualstudio.com/docs/csharp/get-started

🥚FooYoungDevelopmentOP•13mo ago

In my previous 20 assignments it wasn't required. installing it right now. Thanks for the quick response.

Pobiega•13mo ago

its certainly not required but its the recommended way to do C# development in VSC, and afaik currently the only maintained one too the previous extension used something called omnisharp that was notorious for showing incorrect error markers

🥚FooYoungDevelopmentOP•13mo ago

this means I need a newer VSC right?

Pobiega•13mo ago

thats... what thats an ancient version like, over a year or more old

🥚FooYoungDevelopmentOP•13mo ago

Pobiega•13mo ago

current is 1.83

🥚FooYoungDevelopmentOP•13mo ago

On it!

🥚FooYoungDevelopmentOP•13mo ago

RedsSquiglyMess = Solved. 2 follow up questions, I never bothered with installing a new VSC, but, am I supposed to do this manually every month or is it possible to do this internally from VSC?

Pobiega•13mo ago

🥚FooYoungDevelopmentOP•13mo ago

Best Rabbit Ever!

Pobiega•13mo ago

very much doable from inside. Not sure how mac handles it, but I'd be suprised if it doesnt work

🥚FooYoungDevelopmentOP•13mo ago

Thanks for your support, You can mark this case as closed, and I hope to see more of you in the future!
