How do I make a random sequential input?

Questions & Answers
1

I am making a game where I have to input 4-5 buttons in a random sequence every time. There are events in game where you input buttons sequentially. Though each time the game is played, there are different inputs. Is there a way?. Kind of like guitar hero where you make the inputs but with just 4-5 instead of 3-5 minutes. Once the input is done, the event is done.

You can have a data structure like this:

Dictionary<Combo,string> comboStrings = Dictionary<Combo,string>()
{
    {Combo.MeleeAttack, "XAAXB"},
    {Combo.MegaJump, "AAX"},
    {Combo.FastThrow, "XXABB"},
};

–

Combo would be an enum like:

public enum Combo
{
    MeleeAttack,
    MegaJump,
    FastThrow
}

–

Now when you collect input, you add to a size-clamped string, like this – note it doesn’t have to be keyboard-based, e.g. “X” could represent a controller button:

string userInput = "";

void Update()
{
    HandleInput();
}

void HandleInput()
{
    string oldUserInput = userInput;

    if (Input.GetKeyDown("A"))
    {
        userInput += "A";
    }
    else if (Input.GetKeyDown("B"))
    {
        userInput += "B";
    }
    else if (Input.GetKeyDown("X"))
    {
        userInput += "X";
    }
    
    if (userInput != oldUserInput)
    {
        CheckComboTrigger();
        CapStringLength();
    }
}

Then in a function like CheckComboTrigger(), you do:

void CheckComboTrigger()
{
    foreach (KeyValuePair<Combo,string> comboString in comboStrings)
    {
        if (userInput == comboString.Value)
        {
            TriggerCombo(comboString.Key);
            userInput = "";
            break;
        }
    }
}

void TriggerCombo(Combo combo)
{
    switch (combo)
    {
        case Combo.MeleeAttack:
            // Handle this combo.
            break;

        case Combo.MegaJump:
            // Handle this combo.
            break;
    }
}

void CapStringLength()
{
    const int maxLength = 5;
    
    // Add code to cap your string to a max length.
}

You could additionally add code that clears userInput if ever there’s a certain amount of time passed without any input, meaning combos need to be hit fast. Good luck!
