Common（九）—— BeatFlyMotion

来源：互联网发布：药师丸博子知乎编辑：程序博客网时间：2024/06/07 02:53

目录为：Assets/Scripts/Common/，BeatFlyMotion.cs这个文件主要实现一个向上击飞的功能.看一下效果：

这里写图片描述

把脚本挂到一个cube上即可.
下面是代码:

using UnityEngine;using System.Collections.Generic;//击飞运动效果public class BeatFlyMotion: MonoBehaviour{    //当前影响的buff的id    public uint mBuffId = 0;    //默认高度    private float mDefaultHeight;    //向上初始速度    private float mUpSpeed = 0;    //向上加速度    private float mUpAcceleration;    //向下初始速度    private float mDownSpeed = 0;    //向下加速度    private float mDownAcceleration;    //滞空时间    public float mStayTime;    //当前高度    public float mCurrentHeight;    //上次速度    private float mLastSpeed;    //当前速度    private float mCurrentSpeed;    //激活运动    private bool mEnable = false;    //滞空持续时间    private float mTotalStayTime = 0;    //运动方向    //控制是否是向上运动    private bool bDir = true;    //击飞是否能被覆盖    private int mCanBeRecover = 1;    private Transform mTransform = null;    private Animation mAnimation = null;    void Start()    {    }    void OnEnable()    {        //重置数据        mTotalStayTime = 0;        mEnable = false;        bDir = true;        mCanBeRecover = 1;        mBuffId = 0;    }    private Animation GetAnimation()    {        if (mAnimation == null)        {            mAnimation = gameObject.GetComponent<Animation> ();        }        return mAnimation;    }    //击飞    public void BeatFly(uint buffId, string action, float upSpeed = 5, float upAcceleration = -5, float downSpeed = 5, float downAcceleration = 15, float stayTime = 0, int canRecover = 1)    {        //已经是击飞状态        if (mEnable)        {            //Debug.Log("recover state" + mCanBeRecover.ToString());            //已经是击飞状态下，再执行BeatFly时的判断            //可以在空中进行连续的击飞状态            if (mCanBeRecover == 1)            {                Reset ();            }            else            {                return;            }        }        mBuffId = buffId;        //击飞是否被覆盖        mCanBeRecover = canRecover;        //默认高度        mDefaultHeight = gameObject.transform.position.y;        //当前高度        mCurrentHeight = mDefaultHeight;        //mTransform        mTransform = gameObject.transform;        //downAcceleration默认等于5        if (downAcceleration < 0)        {            Debug.LogError ("downAcceleration do not set negative in BeatFly");        }        if (stayTime == 0)        {            stayTime = 0.0001f;        }        mUpSpeed = upSpeed;        mUpAcceleration = upAcceleration;        mDownSpeed = downSpeed;        mDownAcceleration = downAcceleration;        mStayTime = stayTime;        mEnable = true;        //初始速度        mLastSpeed = mUpSpeed;        //当前速度        mCurrentSpeed = mUpSpeed;        //执行被击飞的动作        /*        if (action != "0")        {            GetAnimation ().Play (action);        }        */    }    //立即下落    public void FallNow()    {        mStayTime = 0.0001f;    }    void Update()    {        //击飞运动更新        if (mEnable)        {            //进入滞空状态            //允许滞空mStayTime时间,这个滞空时间不包括下落的时间            //mCurrentSpeed的初始值为mUpSpeed            //当 mCurrentSpeed <= 0 时就是向下运动了            if (mCurrentSpeed <= 0 && mTotalStayTime < mStayTime)            {                mLastSpeed = -mDownSpeed;                mCurrentSpeed = -mDownSpeed;                mTotalStayTime += Time.deltaTime;                bDir = false;                return;            }            //当前速度v = vo + at            //向上运动            if (bDir)            {                mCurrentSpeed = mCurrentSpeed + mUpAcceleration * Time.deltaTime;            }            //向下运动            else            {                //默认的mDownAcceleration要比向上加速度大一些                mCurrentSpeed = mCurrentSpeed - mDownAcceleration * Time.deltaTime;            }            //运动距离            //匀加速直线运动的位移公式(化简过的)            float dist = (mLastSpeed + mCurrentSpeed) * Time.deltaTime * 0.5f;            //当前高度            mCurrentHeight += dist;            //保存前一次的速度            mLastSpeed = mCurrentSpeed;            mTransform.position = new Vector3 (mTransform.position.x, mCurrentHeight, mTransform.position.z);            //回到原来位置或者反向速度为0            if (mCurrentHeight < mDefaultHeight)            {                //Reset后，mEnable为false， 运动也就停了                Reset ();            }        }    }    void Reset()    {        mCurrentHeight = mDefaultHeight;        //重置数据        mTotalStayTime = 0;        mEnable = false;        bDir = true;        mCanBeRecover = 1;        mBuffId = 0;        mTransform.localPosition = new Vector3 (mTransform.localPosition.x, mDefaultHeight, mTransform.localPosition.z);    }    //点击按钮    public void ClickButton()    {        BeatFly (1, "aaa", 5, -5, 5, 5, 0.05f, 1);    }}
