unity中TMP_Text文字显示波浪和上下移动

用sin函数来表示

using UnityEngine;
using TMPro;
using System.Collections;
 
public class WaveTextAnimation : MonoBehaviour
{
    public float amplitude = 0.3f;
    public float frequency = 2f;
 
    private TMP_Text textComponent;
    private string originalText;
 
    private void Start()
    {
        textComponent = GetComponent<TMP_Text>();
        originalText = textComponent.text;
    }
 
 
    private void Update()
    {
        // 根据时间计算波浪形的偏移量
        float offset = Mathf.Sin(Time.time * frequency) * amplitude;
 
        // 应用波浪形偏移量到每个字符
        for (int i = 0; i < originalText.Length; i++)
        {
            TMP_CharacterInfo charInfo = textComponent.textInfo.characterInfo[i];
 
            // 跳过空格和换行符
            if (!char.IsWhiteSpace(originalText[i]))
            {
                int materialIndex = charInfo.materialReferenceIndex;
                int vertexIndex = charInfo.vertexIndex;
 
                // 计算每个字符的顶点偏移
                Vector3[] vertices = textComponent.textInfo.meshInfo[materialIndex].vertices;
                for (int j = 0; j < 4; j++)
                {
                   // vertices[vertexIndex + j] += new Vector3(0f, offset, 0f);
                    var orig = vertices[vertexIndex + j];
 
                    vertices[vertexIndex + j]=orig+new Vector3(0, Mathf.Sin(Time.time*frequency+orig.x*frequency)*amplitude, 0);
                }
            }
        }
 
        // 更新文本网格的顶点信息
        for (int i = 0; i < textComponent.textInfo.meshInfo.Length; i++)
        {
            textComponent.UpdateVertexData(TMP_VertexDataUpdateFlags.All);
        }
    }
 
 
}
