没用raycast投射，使用碰撞检测函数实现了一个平台的小开关
效果是这样的
有点其实也可以不这么复杂的，但是我想起来raycast的时候已经做完了，我还想做点其他的东西，就这样写了
using System.Collections; using System.Collections.Generic; using UnityEngine; public class platformController : MonoBehaviour { // Start is called before the first frame update public GameObject crate;//存放第一个停泊点的位置 public GameObject crate1;//第二个 public GameObject platform;//平台 public float speed; public bool isDown;//开关状态 public bool Trigger = false;//检测是否站在了开关点 Animator animator; public float TriggerTime = 3.0f; private float Timer; void Start() { animator = GetComponent<Animator>(); } // Update is called once per frame void Update() { if (Timer > 0) { if (Input.GetKeyDown(KeyCode.V)) { isDown = !isDown; } Timer -= Time.deltaTime; } else Trigger = false; if (isDown)//如果开关下拉平台往右走，上拉往左走 { Vector2 position = new Vector2(crate1.transform.position.x - 5, platform.transform.position.y); Move(position, Time.deltaTime); } else { Vector2 position = new Vector2(crate.transform.position.x + 5, platform.transform.position.y); Move(position, Time.deltaTime); } if (isDown) animator.SetBool("down", true); else animator.SetBool("down", false); } private void Move(Vector2 position,float dt)//移动 { platform.transform.position = Vector2.MoveTowards(platform.transform.position, position, dt * speed); } private void OnTriggerEnter2D(Collider2D other) { foxcontroller fox = other.gameObject.GetComponent<foxcontroller>(); if (fox != null)//碰撞成功开始计时 { Trigger = true; Timer = TriggerTime; } } }
我这一套写了很多不必要的步骤，全部是按自己的编程习惯来的，有点子复杂与麻烦，还有些漏洞，不过也算是提供一点不那么好的思路吧，可以看一下。
第二个我是写了一个具有特殊效果的奇异果
吃了以后开启超级跳模式，无限跳跃次数，体验上天的感觉
效果是这样的
吃果子之前是这样的
弱，太弱了，所以我们得多寻找这样的奇迹之果（bushi）
代码是这样的
private void superJump()//这里超级跳跃模式 { if (Input.GetKeyDown(KeyCode.Space)) { isjump = true; rb2d.velocity = Vector2.up * jumpForce;//添加力 jumpTime = jumpStartTime; } if(Input.GetKey(KeyCode.Space)&&isjump == true)//甚至还有长跳 { if(jumpTime > 0) { rb2d.velocity = Vector2.up * jumpForce; jumpTime -= Time.deltaTime; } } else { isjump = false; } if (Input.GetKeyUp(KeyCode.Space)) { isjump = false; } } void normalJump() { if (Input.GetKeyDown(KeyCode.Space)&&jump>1) { rb2d.velocity = Vector2.up * jumpForce; jump--; } if (isGround)//落地刷新跳跃次数 { jump = jumpNumber; } }
if (canSuperJumpTime > 0)//这里是控制，剩余超级跳时间 { canSuperJumpTime -= Time.deltaTime; canSuperJump = true; } else canSuperJump = false; if (canSuperJump) { superJump(); } else normalJump();
public class superJump : MonoBehaviour { // Start is called before the first frame update public float canSuperJumpTime; void Start() { } // Update is called once per frame void Update() { } private void OnTriggerEnter2D(Collider2D other) { foxcontroller fox = other.GetComponent<foxcontroller>(); if (fox != null) { fox.canSuperJumpTime = canSuperJumpTime; } Destroy(gameObject); } }
果子的代码很简单，触发器触发以后给角色一个超级跳时间就行了
