Unity中经过任意两点的抛物线运动

需求：一个小怪在空间中任意两点做抛物线运动（开口朝下），并且被英雄攻击后减速。

代码

using UnityEngine;public class TestJump : MonoBehaviour
{public Transform jumpFrom; // 起始点public Transform jumpTo; // 终点private Vector3 posStart, posEnd;public float moveSpeed = 2; // 实际速度public float moveSpeedFixed = 2; // 移动速度public float jumpTime = 1.5f; // 起始点-终点的总时间private float jumpTimer;private bool jumpInit = false;void Update(){if (!jumpInit){posStart = jumpFrom.position;posEnd = jumpTo.position;jumpInit = true;}Jump();}void Jump(){jumpTimer += Time.deltaTime * (moveSpeed / moveSpeedFixed);float f1 = jumpTimer / jumpTime;float f2 = jumpTimer - jumpTimer * f1; // 竖直加速运动Vector3 v1 = Vector3.Lerp(posStart, posEnd, f1); // 水平匀速运动transform.position = v1 + f2 * Vector3.up;if (jumpTimer >= jumpTime){jumpTimer = 0;jumpInit = false;}}
}

这个减速仍然沿着原路线运动只是速度减慢，如果要模拟真实的在抛物线运动中被英雄子弹击中后的减速运动，只需根据英雄子弹的方向，调整小怪的水平和竖直速度即可。
