Unity组件开发--升降梯

        我开发的升降梯由三个部分组成，反正适用于我的需求了，其他人想复用到自己的项目的话，不一定。写的也不是很好，感觉搞的有点复杂啦。完全可以在优化一下，项目赶工期，就先这样吧。能用就行，其他的再说。

1.升降梯基类：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public abstract class LiftObjCtrBase : MonoBehaviour
{public float speed = 5f;  // 上升和下降的速度public LiftObjCtrBase targetObject;  // 指定的物体高度[HideInInspector]public bool isRising = false;  // 是否正在上升[HideInInspector]public bool isFalling = false;  // 是否正在下降[HideInInspector]public bool isPlayerStay = false; //玩家是否在上面[HideInInspector]public Vector3 initialPosition;  // 初始位置[HideInInspector]public float offsetY = 0;[HideInInspector]public Transform playerTra;[HideInInspector]public Transform targetTra;[HideInInspector]public float radius = 0;// Start is called before the first frame update[HideInInspector]public bool isReach = false;public virtual bool isTriggerEnter(Transform playerTra) {if (Vector3.Distance(gameObject.transform.position, playerTra.position) > radius){return false;}else{return true;}}public virtual void startRising() {}}

2.玩家接触到的头一个升降梯：第一个升降梯的碰撞组件，必须开启isTrigger属性；注意：所有升降梯都需要挂碰撞组件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.TextCore.Text;public class LiftFirstObjCtr : LiftObjCtrBase
{//private Transform player;  // 角色private void Start(){initialPosition = transform.position;  // 记录初始位置targetTra = targetObject.gameObject.transform;MeshCollider meshCollider = gameObject.GetComponent<MeshCollider>();radius = meshCollider.bounds.extents.magnitude;}private void Update(){if (targetObject == null) return;if (playerTra != null && !isTriggerEnter(playerTra) && !isFalling){isPlayerStay = false;isFalling = true;isRising = false;}if (playerTra !=null && targetObject.isTriggerEnter(playerTra) && !targetObject.isRising && !targetObject.isReach){isPlayerStay = false;isFalling = true;targetObject.startRising();}if (isRising && isPlayerStay){// 上升逻辑if (playerTra == null || offsetY == 0) return;transform.Translate(Vector3.up * speed * Time.deltaTime);playerTra.position = new Vector3(playerTra.position.x, transform.position.y+ offsetY+0.4f, playerTra.position.z);// 到达目标高度后开始下降if (transform.position.y >= targetTra.position.y){gameObject.GetComponent<Collider>().isTrigger = false;isRising = false;}}else if (isFalling && !isPlayerStay){// 下降逻辑transform.Translate(Vector3.down * speed * Time.deltaTime);// 返回初始位置后停止下降if (transform.position.y <= initialPosition.y){transform.position = initialPosition;isFalling = false;gameObject.GetComponent<Collider>().isTrigger = true;}}}private void OnTriggerEnter(UnityEngine.Collider other){if (other.gameObject.tag == "Player"){Debug.Log("玩家撞到升降梯");}}public override bool isTriggerEnter(Transform playerTra) {// 检测角色是否在碰撞器范围内if (Vector3.Distance(gameObject.transform.position, playerTra.position) > radius){return false;}else {return true;}}private void OnTriggerStay(UnityEngine.Collider other){if (other.gameObject.tag == "Player" && !isPlayerStay){if (Vector3.Distance(other.gameObject.transform.position, gameObject.transform.position)< radius) {Debug.Log("玩家待在升降梯");isRising = true;playerFollow(other.gameObject);gameObject.GetComponent<Collider>().isTrigger = false;}}}private void OnTriggerExit(UnityEngine.Collider other){}private void playerFollow(GameObject player) {offsetY = player.transform.position.y - transform.position.y;playerTra = player.transform;isPlayerStay = true;}public override void startRising(){}
}

3.中间的其他升降梯，其他中间的升降梯由于是悬浮在空中的，所以需要不能开启isTrigger属性，否则玩家碰到后就会掉下去：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.TextCore.Text;public class LiftMiddleObjCtr : LiftObjCtrBase
{public LiftObjCtrBase preLiftObj;// Update is called once per frameprivate void Start(){initialPosition = transform.position;  // 记录初始位置targetTra = targetObject.transform;MeshCollider meshCollider = gameObject.GetComponent<MeshCollider>();radius = meshCollider.bounds.extents.magnitude;}void Update(){if (targetObject == null) return;if (playerTra != null && !isTriggerEnter(playerTra) && !isFalling){isPlayerStay = false;isFalling = true;isRising = false;return;}if (playerTra != null && targetObject.isTriggerEnter(playerTra) && !targetObject.isRising){isPlayerStay = false;isFalling = true;targetObject.startRising();playerTra = null;}if (isRising && isPlayerStay){// 上升逻辑if (playerTra == null || offsetY == 0) return;transform.Translate(Vector3.up * speed * Time.deltaTime);playerTra.position = new Vector3(playerTra.position.x, transform.position.y + offsetY + 0.4f, playerTra.position.z);// 到达目标高度后开始下降if (transform.position.y >= targetTra.position.y){isRising = false;isReach = true;}}else if (isFalling && !isPlayerStay){// 下降逻辑transform.Translate(Vector3.down * speed * Time.deltaTime);// 返回初始位置后停止下降if (transform.position.y <= initialPosition.y){transform.position = initialPosition;isFalling = false;isReach = false;isRising = false;}}}public override bool isTriggerEnter(Transform playerTra){if (Vector3.Distance(gameObject.transform.position, playerTra.position) > radius){return false;}else{return true;}}public override void startRising() {isRising = true;playerFollow(preLiftObj.playerTra.gameObject);gameObject.GetComponent<Collider>().isTrigger = false;}private void playerFollow(GameObject player){offsetY = player.transform.position.y - transform.position.y;playerTra = player.transform;isPlayerStay = true;}
}

4.最后一个升降梯，是玩家最终达到的升降梯，所以可以不用升降，他是出发倒数第二个升降梯的下降：感觉有点奇怪，反正整个组件都开发的感觉奇奇怪怪的，算了算了，咱也没啥要求，混口饭吃，能较差就行

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class LiftLastObjCtr : LiftObjCtrBase
{// Start is called before the first frame updatepublic LiftMiddleObjCtr middleObject;public override bool isTriggerEnter(Transform playerTra){return false;}public override void startRising(){}// Update is called once per framevoid Update(){if (middleObject != null && middleObject.playerTra != null) {if (Vector3.Distance(middleObject.playerTra.position,gameObject.transform.position) < 1) {if (Vector3.Distance(middleObject.playerTra.position, middleObject.gameObject.transform.position) > 1){middleObject.isFalling = true;middleObject.isPlayerStay = false;}}}}}
