这里将视频中的代码放在这里：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Player : MonoBehaviour
{
float speed = 5;
public Image background;
public Text contetnTxt;
GameObject obj = null;
bool isPick = false;
void Start()
{
background.gameObject.SetActive(false);
}
void Update()
{
if (Input.GetKey(KeyCode.W))
{
transform.Translate(Vector3.forward * speed * Time.deltaTime);
}
else if (Input.GetKey(KeyCode.S))
{
transform.Translate(Vector3.back * speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.A))
{
transform.Translate(Vector3.left * speed * Time.deltaTime);
}
else if (Input.GetKey(KeyCode.D))
{
transform.Translate(Vector3.right * speed * Time.deltaTime);
}
if (Input.GetKeyDown(KeyCode.F) && obj)
{
isPick = !isPick;
if (isPick)
{
contetnTxt.text = "F 放置";
obj.transform.parent = transform;
}
else
{
contetnTxt.text = "F 拾取";
obj.transform.parent = null;
}
}
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject)
{
obj = other.gameObject;
background.gameObject.SetActive(true);
}
}
private void OnTriggerExit(Collider other)
{
obj = null;
background.gameObject.SetActive(false);
}
}
