我在制作一串字符数组以在 Unity 引擎中打印到屏幕时遇到问题。

这里是代码

{
    public string[] wordGoDownString = new string[12];   

    public void Start()
    {
        char[] chwordGoDownString = wordGoDownString.ToCharArray();
        foreach (char ch in wordGoDownString)
        {

        }
        //char[]wordGoDownString[0] = 'O';
        //char[]wordGoDownString[1] = 'U';
        //char[]wordGoDownString[2] = 'R';
        //char[]wordGoDownString[3] = " ";
        //char[]wordGoDownString[4] = 'P';
        //char[]wordGoDownString[5] = 'R';
        //
        //Print.ToScreen(chars);
        //Print.ToScreen(' ');

        //wordGoDownString[6] = 
        //wordGoDownString[7] = 
        //wordGoDownString[8] = 
        //wordGoDownString[9] = 
        //wordGoDownString[10] =
        //wordGoDownString[11] =
    }
}
   
//     [SerializeField] private string thatString = "b";
//     string yellTheString;
// 
//     public void Start()
//     {
//         foreach (char chars in thatString)
//         {
//             char higherChars = char.ToUpper(chars);
//             yellTheString += higherChars;
//         }
//         Print.ToScreen(yellTheString);
//     }
//     // YellTheString
// }

//SerializeField] private char charLettersDown1 = 'O';
//
//rivate char string [] thatString = new string[12]; 
//
//ublic void Start()
//
//thatString[0] = 'O';
//thatString[1] = 'U';

//thatString[7] = 'N';
//thatString[8] = 'C';
//thatString[9] = 'E';
//thatString[10] = 'S';
//thatString[11] = 'S';
//
//
//
/// Borrowing this from the school's code documents.
//
//

在我看来，您可能想要一个一次只显示一个字符的横幅，例如

public float delayPerChar = 1f;
public float delayBetweenWords = 1f;

public string[] wordGoDownString = new string[12];  

private string currentWord;
private int currentWordIndex;
private int currentCharIndex; 

private float timer;

private string currentPrint;

private void Update ()
{
    timer += Time.deltaTime;

    // Is currentWord null or whitespace?
    if(string.NullOrWhiteSpace(currentWord))
    {
        // If that's the case we are currently between two words
        // Has the delays exceeded?
        if(timer >= delayBetweenWords)
        {
            // If so pick the next word from the list with wrap around at the end
            currentWordIndex = (currentWordIndex + 1) % wordGoDownString.Length;
            currentWord = wordGoDownString[currentWordIndex];

            // Reset the chat index
            currentCharIndex = 0;
            // Reset the timer
            timer = 0f;
            // Reset the current Print 
            currentPrint = "";

            // print the first char of the current word
            currentPrint += currentWorld[currentCharIndex];
            Print.PrintToScreen(currentPrint);
            // Rest if the word is handled in the else case
        }
    }
    else
    {
        // Go to the next char 
        currentCharIndex += 1;

        currentPrint += currentWord [currentCharIndex];

        // reset timer to wait for next char
        timer = 0f;

        // Is this the last in the current word?
        if(currentCharIndex => currentWord.Length - 1)
        {
            // reset currentWord in order to go to next word
            currentWord = null;
        }       
    }
}

使用Coroutines 会更容易一些！

与 Coroutine 的代码基本相同

// Yes, if you make Start return IEnumerator then Unity automatically runs it as Coroutine
private IEnumerator Start ()
{
    // This is OK in Coroutines as long as you yield somewhere inside
    while(true)
    {
        // Simply iterate the words
        foreach(var currentWord in wordGoDownString)
        {
            // For each word start with an empty print
            var currentPrint = "";
            
            // Simply iterate the chars
            foreach(var currentChar in currentWord.ToCharArray())
            {
                // Append the char and print
                currentPrint += currentChar;
                Print.PrintToScreen(currentPrint);

                // Then wait for the delay
                yield return new WaitForSeconds (delayPerChar);
            }

            // after each word wait for the other delay
            yield return new WaitForSeconds(delayBetweenWords);
        }
    }
}
