英文:
Why doesn't the distance change?
问题
我正在尝试创建一个代码，当靠近可以交互的对象时，立即显示我的用户界面。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class pop_up : MonoBehaviour
{
[SerializeField] private CanvasGroup myUIGroup;
public float maxDistance;
public GameObject player;
public GameObject interactible;
public float distance;
void Update()
{
distance = Vector3.Distance(player.transform.position, interactible.transform.position);
if (distance <= maxDistance)
{
ShowUI();
}
else
{
HideUI();
}
}
public void ShowUI()
{
myUIGroup.alpha = 1;
}
public void HideUI()
{
myUIGroup.alpha = 0;
}
}
我尝试靠近对象，但UI没有出现，距离保持为0。
英文:
Im trying to create a code that instantly makes my UI appear when close enough to an object that can be interacted with.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class pop_up : MonoBehaviour
{
[SerializeField] private CanvasGroup myUIGroup;
public float maxDistance;
public GameObject player;
public GameObject interactible;
public float distance;
void update()
{
distance = Vector3.Distance(player.transform.position, interactible.transform.position);
if (distance <= maxDistance)
{
ShowUI();
}
else
{
HideUI();
}
}
public void ShowUI()
{
myUIGroup.alpha = 1;
}
public void HideUI()
{
myUIGroup.alpha = 0;
}
}
I tried to walk close to the object and have the UI appear, but nothing changed and the distance stayed 0.

C#是区分大小写的，应该是void Update()而不是void update()。
英文:
C# is case sensitive, it should be void Update() not void update().
