Unity中实现数字上升效果(一个数字动态变化到另一个数字)

一：效果演示

二：实现

using UnityEngine;
 
/// <summary>
/// 数字上升效果
/// </summary>
public class ChangeNum : MonoBehaviour
{
    /// <summary>
    /// 数字变化
    /// </summary>
    /// <param name="initNum">初始数字</param>
    /// <param name="showNum">显示的数字(结果)</param>
    /// <param name="targetNum">目标数字</param>
    /// <param name="v">Linear：时间    EaseOut：比例值</param>
    /// <param name="changeType">变化类型</param>
    public static double NumberChange(double initNum, double showNum, double targetNum, float v, ChangeType changeType = ChangeType.Linear)
    {
        switch (changeType)
        {
            case ChangeType.Linear:
                showNum += (targetNum - initNum) * Time.deltaTime / v;
                if (showNum >= targetNum)
                {
                    showNum = targetNum;
                }
                return showNum;
            case ChangeType.EaseIn:
                return showNum;
            case ChangeType.EaseOut:
                showNum += (targetNum - showNum) * Time.deltaTime / v;
                return showNum;
            default:
                return 0;
        }
    }
}
 
/// <summary>
/// 变化速度的类型
/// </summary>
public enum ChangeType
{
    Linear,//线性
    EaseIn,//先慢后快
    EaseOut,//先快后慢
}
