本文详细介绍了一种在Unity中实现物体跟随特定目标物体移动的方法。通过调整组件参数，可以控制跟随物体沿X、Y、Z轴或其组合进行平滑跟随。代码使用了Mathf.Lerp函数确保移动过程平滑过渡。

跟随某个物体（具体哪个轴/或完全跟随）运动详解

//跟随某个物体移动
使用方式：
1.如果勾选x轴就只跟随那个物体的x轴移动
2.如果勾选x和y轴就只跟随那个物体的x和y轴移动
3.如果全勾选就跟随那个物体移动，都不勾选就都不跟随
代码比较简单，就不过多注释，直接使用就好

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GenSui : MonoBehaviour {

private Transform pos;
[Header("【需要跟随的物体】")]
public Transform Pos;
public float Speed = 20f;
public bool X = false; 
public bool Y = false;
public bool Z = false;

// Use this for initialization
void Awake () {
    pos = transform;
}
// Update is called once per frame
void Update () {
    //只勾选一个轴的
    if (X== true && Y == false && Z == false)
    {
        float x = Mathf.Lerp(pos.position.x, Pos.position.x, Time.deltaTime * Speed);
        pos.position = new Vector3(x, pos.position.y, pos.position.z);
    }
    else if (X == false  && Y == true && Z == false)
    {
        float y = Mathf.Lerp(pos.position.y, Pos.position.y, Time.deltaTime * Speed);
        pos.position = new Vector3(pos.position.x, y, pos.position.z);
    }
    else if (X == false && Y == false && Z == true) 
    {
        float z = Mathf.Lerp(pos.position.z, Pos.position.z, Time.deltaTime * Speed);
        pos.position = new Vector3(pos.position.x, pos.position.y, z);
    }
    //勾选其中两个的
    else if(X == true && Y == true && Z == false)
    {
        float x1 = Mathf.Lerp(pos.position.x, Pos.position.x, Time.deltaTime * Speed);
        float y1 = Mathf.Lerp(pos.position.y, Pos.position.y, Time.deltaTime * Speed);
        pos.position = new Vector3(x1, y1, pos.position.z);
    }
    else if (X == true && Y == false && Z == true)
    {
        float x1 = Mathf.Lerp(pos.position.x, Pos.position.x, Time.deltaTime * Speed);
        float z1 = Mathf.Lerp(pos.position.z, Pos.position.z, Time.deltaTime * Speed);
        pos.position = new Vector3(x1, pos.position.y, z1);
    }
    else if (X == false && Y == true && Z == true)
    {
        float y1 = Mathf.Lerp(pos.position.y, Pos.position.y, Time.deltaTime * Speed);
        float z1 = Mathf.Lerp(pos.position.z, Pos.position.z, Time.deltaTime * Speed);
        pos.position = new Vector3(pos.position.x, y1, z1);
    }
    //三个全部勾上
    else if (X == true && Y == true && Z == true)
    {
        float x1 = Mathf.Lerp(pos.position.x, Pos.position.x, Time.deltaTime * Speed);
        float y1 = Mathf.Lerp(pos.position.y, Pos.position.y, Time.deltaTime * Speed);
        float z1 = Mathf.Lerp(pos.position.z, Pos.position.z, Time.deltaTime * Speed);
        pos.position = new Vector3(x1, y1, z1);
    }
}
