Unity3D_(游戏)控制物体的上、下、左、右移动

　　通过键盘上↑、↓、←、→实现对物体的控制

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Gary_Text : MonoBehaviour {public Transform WuTi;public float speed = 1;// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {//上if(Input.GetKey(KeyCode.UpArrow)){transform.eulerAngles = new Vector3(0, 0, 0);transform.position += transform.forward * speed;}//下else if (Input.GetKey(KeyCode.DownArrow)){transform.eulerAngles = new Vector3(0, 180, 0);transform.position += transform.forward * speed;}//左else if (Input.GetKey(KeyCode.LeftArrow)){transform.eulerAngles = new Vector3(0, 270, 0);transform.position += transform.forward * speed;}//右else if (Input.GetKey(KeyCode.RightArrow)){transform.eulerAngles = new Vector3(0, 90, 0);transform.position += transform.forward * speed;}}
}

Gary_Text.cs 控制物体移动脚本

实现过程

　　GameObject->3D Object->Sphere创建一个Sphere作为被移动物体对象

　　在Sphere物体上绑定Gary_Text.cs脚本

　　可以在工程界面修改游戏速度speed值，默认是1

　　 //引用控制移动物体脚本public Transform WuTi;//设置物体移动的速度，设置为public使在游戏界面可控制public float speed = 1;

　　在Updata()中跟新物体的坐标

void Update () {//上if(Input.GetKey(KeyCode.UpArrow)){transform.eulerAngles = new Vector3(0, 0, 0);transform.position += transform.forward * speed;}//下else if (Input.GetKey(KeyCode.DownArrow)){transform.eulerAngles = new Vector3(0, 180, 0);transform.position += transform.forward * speed;}//左else if (Input.GetKey(KeyCode.LeftArrow)){transform.eulerAngles = new Vector3(0, 270, 0);transform.position += transform.forward * speed;}//右else if (Input.GetKey(KeyCode.RightArrow)){transform.eulerAngles = new Vector3(0, 90, 0);transform.position += transform.forward * speed;}}
