大家好，我是心疼你的一切，不定时更新Unity开发技巧，觉得有用记得一键三连哦。

前言

人物移动代码综合记录一下(因为有很多种).所以简单记录一下

---

一、人物移动之键盘移动

所谓键盘移动就是我们常玩游戏的操作 wasd来进行移动

1-1、代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerToKeyPad : MonoBehaviour
{public GameObject Player;public float m_speed = 5f;void Update(){//键盘控制移动 两种方法PlayerMove_KeyPad_1();PlayerMove_KeyPad_2();}//通过Transform组件 键盘控制移动public void PlayerMove_KeyPad_1(){if (Input.GetKey(KeyCode.W) | Input.GetKey(KeyCode.UpArrow)) //前{Player.transform.Translate(Vector3.forward * m_speed * Time.deltaTime);}if (Input.GetKey(KeyCode.S) | Input.GetKey(KeyCode.DownArrow)) //后{Player.transform.Translate(Vector3.forward * -m_speed * Time.deltaTime);}if (Input.GetKey(KeyCode.A) | Input.GetKey(KeyCode.LeftArrow)) //左{Player.transform.Translate(Vector3.right * -m_speed * Time.deltaTime);}if (Input.GetKey(KeyCode.D) | Input.GetKey(KeyCode.RightArrow)) //右{Player.transform.Translate(Vector3.right * m_speed * Time.deltaTime);}}public void PlayerMove_KeyPad_2(){float horizontal = Input.GetAxis("Horizontal"); //A D 左右float vertical = Input.GetAxis("Vertical"); //W S 上 下Player.transform.Translate(Vector3.forward * vertical * m_speed * Time.deltaTime);//W S 上 下Player.transform.Translate(Vector3.right * horizontal * m_speed * Time.deltaTime);//A D 左右}
}

二、人物移动之跟随鼠标点击移动

2-1、代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerToMouse : MonoBehaviour
{public GameObject Player;Vector3 tempPoint = new Vector3(0, 0, 0);void Update(){PlayerMove_FollowMouse();}//角色移动到鼠标点击的位置public void PlayerMove_FollowMouse(){//右键点击if (Input.GetMouseButtonDown(1)){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hitInfo;if (Physics.Raycast(ray, out hitInfo)){tempPoint = new Vector3 ( hitInfo.point.x, hitInfo.point.y+0.5f, hitInfo.point.z);}}float step = 10 * Time.deltaTime;Player.transform.localPosition = Vector3.MoveTowards(Player.transform.localPosition, tempPoint, step);Player.transform.LookAt(tempPoint);}
}

三、人物移动之刚体移动

里面包含两个方法一个是：Velocity移动 一个是：AddForce移动

3-1、代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerToRigidbody : MonoBehaviour
{public GameObject Player;public float m_speed = 5f;void Update(){//PlayerMove_KeyRighidbody1();PlayerMove_KeyRighidbody2();}//通过Rigidbody组件 键盘控制移动 Velocity移动 角色身上需要挂载Rigidbody组件public void PlayerMove_KeyRighidbody1(){float horizontal = Input.GetAxis("Horizontal"); //A D 左右float vertical = Input.GetAxis("Vertical"); //W S 上 下//这个必须分开判断 因为一个物体的速度只有一个if (Input.GetKey(KeyCode.W) | Input.GetKey(KeyCode.S)){Player.GetComponent<Rigidbody>().velocity = Vector3.forward * vertical * m_speed;}if (Input.GetKey(KeyCode.A) | Input.GetKey(KeyCode.D)){Player.GetComponent<Rigidbody>().velocity = Vector3.right * horizontal * m_speed;}}//通过Rigidbody组件 键盘控制移动 AddForce移动 角色身上需要挂载Rigidbody组件public void PlayerMove_KeyRighidbody2(){float horizontal = Input.GetAxis("Horizontal"); //A D 左右float vertical = Input.GetAxis("Vertical"); //W S 上 下Player.GetComponent<Rigidbody>().AddForce(Vector3.forward * vertical * m_speed);Player.GetComponent<Rigidbody>().AddForce(Vector3.right * horizontal * m_speed);}}

3-2、效果

四、人物移动之第一人称控制器移动

里面包含两个方法一个是：SimpleMove控制移动 一个是：Move控制移动

4-1、代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerToCharacterController : MonoBehaviour
{public GameObject Player;public float m_speed = 5f;void Update(){//PlayerMove_KeyCharacterController1();PlayerMove_KeyCharacterController2();}//通过CharacterController组件 键盘移动物体 SimpleMove控制移动public void PlayerMove_KeyCharacterController1(){float horizontal = Input.GetAxis("Horizontal"); //A D 左右float vertical = Input.GetAxis("Vertical"); //W S 上 下if (horizontal !=0&&vertical ==0){Player.GetComponent<CharacterController>().SimpleMove(transform.right * horizontal * m_speed);}else if (horizontal == 0 && vertical != 0){Player.GetComponent<CharacterController>().SimpleMove(transform.forward * vertical * m_speed);}else{//斜着走 例如w a一起按Player.GetComponent<CharacterController>().SimpleMove(transform.forward * vertical * m_speed);Player.GetComponent<CharacterController>().SimpleMove(transform.right * horizontal * m_speed);}}//通过CharacterController组件 键盘移动物体 Move控制移动public void PlayerMove_KeyCharacterController2(){float horizontal = Input.GetAxis("Horizontal"); //A D 左右float vertical = Input.GetAxis("Vertical"); //W S 上 下float moveY = 0;float m_gravity = 10f;moveY -= m_gravity * Time.deltaTime;//重力Player.GetComponent<CharacterController>().Move(new Vector3(horizontal, moveY, vertical) * m_speed * Time.deltaTime);}}

4-2、效果

五、Android触摸手势操作脚本（单指 双指 三指）

相机设置如下

单指移动，双指缩放 ， 三指旋转
移动和旋转动的是Pivot 缩放动的是Main Camera的Z轴距离

5-1、代码如下

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class TouchMove : MonoBehaviour
{public Camera cameraMainTrans;public Transform rotTransform;private float zoomSpeed = 0.1f;private float rotateSpeed = 0.5f;private float moveSpeed = 0.1f;private Vector2 prevPos1, prevPos2,prevPos3;private float prevDistance;void Update(){// 处理单指触摸平移if (Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Moved){Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;float tranY = touchDeltaPosition.y * (float)Math.Sin(Math.Round(this.transform.localRotation.eulerAngles.x, 2) * Math.PI / 180.0);float tranZ = touchDeltaPosition.y * (float)Math.Cos(Math.Round(this.transform.localRotation.eulerAngles.x, 2) * Math.PI / 180.0);rotTransform.Translate(new Vector3(touchDeltaPosition.x, tranY, tranZ) * moveSpeed, Space.Self);Debug.Log(touchDeltaPosition.x + "单指横向+纵向+" + touchDeltaPosition.y);}// 处理双指触摸缩放if (Input.touchCount == 2){Touch touch1 = Input.GetTouch(0);Touch touch2 = Input.GetTouch(1);// 获取距离和位置的差异Vector2 curPos1 = touch1.position;Vector2 curPos2 = touch2.position;float curDistance = Vector2.Distance(curPos1, curPos2);if (touch2.phase == TouchPhase.Began){prevPos1 = curPos1;prevPos2 = curPos2;prevDistance = curDistance;}// 缩放摄像机float deltaDistance = curDistance - prevDistance;cameraMainTrans.transform.Translate(Vector3.back * -deltaDistance * 0.1f);// 更新变量prevPos1 = curPos1;prevPos2 = curPos2;prevDistance = curDistance;}// 处理三指触摸旋转if (Input.touchCount == 3){Touch touch1 = Input.GetTouch(0);Touch touch2 = Input.GetTouch(1);Touch touch3 = Input.GetTouch(2);// 获取触摸位置的差异Vector2 curPos1 = touch1.position;Vector2 curPos2 = touch2.position;Vector2 curPos3 = touch3.position;Vector2 deltaPos1 = curPos1 - prevPos1;Vector2 deltaPos2 = curPos2 - prevPos2;Vector2 deltaPos3 = curPos3 - prevPos3;if (touch2.phase == TouchPhase.Moved){// 计算横向旋转float horizontalRotation = deltaPos1.x * rotateSpeed;rotTransform.Rotate(Vector3.up, horizontalRotation);// 计算纵向旋转float verticalRotation = -deltaPos1.y * rotateSpeed;Vector3 verticalRotationAxis = rotTransform.TransformVector(Vector3.left);rotTransform.RotateAround(rotTransform.position, verticalRotationAxis, verticalRotation);}// 更新变量prevPos1 = curPos1;prevPos2 = curPos2;prevPos3 = curPos3;}else if (Input.touchCount == 0){// 清除前一帧的触摸位置prevPos1 = Vector2.zero;prevPos2 = Vector2.zero;prevPos3 = Vector2.zero;}}private static float ClampAngle(float angle, float min, float max){if (angle < -360)angle += 360;if (angle > 360)angle -= 360;return Mathf.Clamp(angle, min, max);}
}

不定时更新Unity开发技巧，觉得有用记得一键三连哦。
防止后面忘记，所以记录一下
