Unity 入门打字机效果

使用协程加延迟

public class UIDazhi : MonoBehaviour
{
    public Text t;
    //private string currentstr = "";
    public string str = "欢迎来到Unity的世界";
    // Start is called before the first frame update
    void Start()
    {
        Debug.Log("12");
        t.text = "";
        StartCoroutine( Fade());
    }
    
    IEnumerator Fade()
    {
        yield return null;
        for (int i = 0; i <= str.Length; i++)
        {
            Debug.Log("sadf");
            t.text = str.Substring(0, i);
            yield return new WaitForSeconds(0.5f);//延迟0.5秒
        }
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}
