一般在游戏中都会需要有物品掉落的表现,今天就编写了一个通用的模拟原地抛物线的脚本,适用于物品在怪物身上掉落时的表现。

using UnityEngine;using System.Collections;public class Drop : MonoBehaviour{    public GameObject go;    private float _a = 0.0f;    private float _b = 0.0f;    public float jumpDuration = 3f; //弹起的时间    public float height = 50; //弹起的高度    private float _curTime = 0.0f;    public int count = 3; //弹起的次数    private Vector3 _homePos = Vector3.zero;    private Vector3 _tempPos = Vector3.zero;    void Start()    {        _homePos = go.transform.position;        CalculateAAndB();    }    private void CalculateAAndB()    {        _a = -4 * height / Mathf.Pow(jumpDuration, 2);        _b = _a * (-1) * jumpDuration;    }    // Update is called once per frame    void Update()    {        if (gameObject)        {            if (_curTime < jumpDuration)            {                _curTime += Time.deltaTime;                _tempPos = _homePos + (_a * Mathf.Pow(_curTime, 2) + _b * _curTime) * Vector3.up;                go.transform.position = _tempPos;            }            else if (count > 0)            {                count = count - 1;                _curTime = 0;                height = 0.5f * height;                jumpDuration = 0.5f * jumpDuration;                CalculateAAndB();            }        }    }}
