程式可以正常運行，但是不知道哪里出問題了，一直在報錯
百度后看到有人說是參考的實體物件未定義，剛學C#和unity，沒看出哪個沒被定義，救救孩子吧
附上使用的兩段腳本
腳本1：Playercontrol.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Playercontrol : MonoBehaviour
{
public float speed = 10f;
private int Maxhealth = 3;//最大生命值
private int Currenthealth=2;//當前生命值
public int Gamingmaxhealth { get { return Maxhealth; } }
public int Gaminghealth { get { return Currenthealth; } }
Rigidbody2D rbody;//定義剛體rbody
// Start is called before the first frame update
void Start()
{
rbody = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update()
{
float moveX = Input.GetAxisRaw("Horizontal");//水平方向移動，A:-1 D:1 0
// 目前先禁用 float moveY = Input.GetAxisRaw("Vertical");//垂直方向移動，W:1,S:-1 0
Vector2 position = rbody.position;
position.x += moveX * speed * Time.deltaTime;
//禁 position.y += moveY * speed * Time.deltaTime;
rbody.MovePosition(position);
}
//改變玩家的生命值
public void Changehealth(int aomunt)
{
Currenthealth = Mathf.Clamp(Currenthealth + aomunt, 0, Maxhealth);
Debug.Log(Currenthealth+"/"+Maxhealth);
}
}
腳本2：Healthcollect.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//回血道具碰撞檢測
public class Healthcollect : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
}
private void OnTriggerEnter2D(Collider2D other)
{
Playercontrol pc = other.GetComponent<Playercontrol>();
if (pc != null) { Debug.Log("玩家碰到櫻桃"); }
if (pc.Gaminghealth < pc.Gamingmaxhealth)
{
pc.Changehealth(1);
Destroy(this.gameObject);
}
}
}

雙擊報錯看看是否指定了某句代碼uj5u.com熱心網友回復：
是在unity的控制臺報錯的，找不到指向uj5u.com熱心網友回復：
應該是你UI設定的問題你把UI禁了試試看轉載請註明出處，本文鏈接：https://www.uj5u.com/qita/14059.html
