Unity中实现“打字机效果”。

在 Unity 中实现“打字机效果”（Typewriter Effect），用于逐字显示文本，营造出像是打字机逐字打出文字的效果

使用 UnityEngine.UI 的 Text 实现（适用于旧版 UI）

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class TypewriterEffect : MonoBehaviour
{
    public Text targetText;         // 要应用打字机效果的 Text 组件
    public float typingSpeed = 0.05f; // 每个字符之间的间隔时间（秒）

    private string fullText;
    private bool isTyping = false;

    void Start()
    {
        if (targetText == null)
            targetText = GetComponent<Text>();

        if (targetText != null)
        {
            fullText = targetText.text;
            targetText.text = "";
            StartTyping();
        }
    }

    public void StartTyping()
    {
        if (!isTyping)
        {
            StartCoroutine(TypeText());
        }
    }

    IEnumerator TypeText()
    {
        isTyping = true;
        targetText.text = "";

        foreach (char c in fullText.ToCharArray())
        {
            targetText.text += c;
            yield return new WaitForSeconds(typingSpeed);
        }

        isTyping = false;
    }

    // 可选：立即显示全部文本
    public void SkipTyping()
    {
        StopAllCoroutines();
        targetText.text = fullText;
        isTyping = false;
    }
}

使用 TextMeshPro（推荐，功能更强）

using UnityEngine;
using TMPro;
using System.Collections;

public class TypewriterEffectTMP : MonoBehaviour
{
    public TMP_Text targetText;
    public float typingSpeed = 0.05f;

    private string fullText;
    private bool isTyping = false;

    void Start()
    {
        if (targetText == null)
            targetText = GetComponent<TMP_Text>();

        if (targetText != null)
        {
            fullText = targetText.text;
            targetText.text = "";
            StartTyping();
        }
    }

    public void StartTyping()
    {
        if (!isTyping)
        {
            StartCoroutine(TypeText());
        }
    }

    IEnumerator TypeText()
    {
        isTyping = true;
        targetText.text = "";

        foreach (char c in fullText.ToCharArray())
        {
            targetText.text += c;
            yield return new WaitForSeconds(typingSpeed);
        }

        isTyping = false;
    }

    public void SkipTyping()
    {
        StopAllCoroutines();
        targetText.text = fullText;
        isTyping = false;
    }
}
