unity3d物体悬浮效果

要实现Unity3D物体的悬浮效果，可以使用脚本来控制物体的上下浮动。可以参考以下代码实现悬浮效果：

using UnityEngine;

public class Floating : MonoBehaviour
{
    float radian = 0; // 弧度
    float perRadian = 0.03f; // 每次变化的弧度
    float radius = 0.8f; // 半径
    Vector3 oldPos; // 开始时候的坐标

    void Start()
    {
        oldPos = transform.position; // 将最初的位置保存到oldPos
    }

    void Update()
    {
        radian += perRadian; // 弧度每次加0.03
        float dy = Mathf.Cos(radian) * radius; // dy定义的是针对y轴的变量，也可以使用sin，找到一个适合的值就可以
        transform.position = oldPos + new Vector3(0, dy, 0);
    }
}

这段代码会让物体在上下浮动，可以根据需要调整浮动的幅度和速度。将该脚本挂载到需要悬浮的物体上即可实现悬浮效果。\[1\]

希望对你有所帮助！
