英文:
Make player go through walls (one way wall )
问题
我游戏中有一个功能，需要玩家穿过墙壁来解决谜题，我希望玩家只能穿过带有“Puzzle Wall”标签的墙壁一次，然后在时间结束后它将不再起作用（变成普通墙壁）。
如何使其工作（您可以编写新的代码，因为我的代码有2个错误）
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Walls : MonoBehaviour
{
private BoxCollider boxCollider;
private bool hasBeenActivated = false;
void Start()
{
Puzzle.OnPuzzleSolved += ActivateWall;
boxCollider = GetComponent<BoxCollider>();
}
void Update()
{
}
private void OnTriggerExit(Collider other)
{
if (hasBeenActivated)
{
boxCollider.isTrigger = false;
}
}
private void ActivateWall(string wallTypeToActivate)
{
if (!hasBeenActivated && wallTypeToActivate == "Puzzle Wall")
{
boxCollider.isTrigger = true;
hasBeenActivated = true;
}
}
}
错误1：我不能将任何内容传递给我的动作
错误2：空引用异常
错误3：玩家可以穿过所有墙壁
我尝试使用OnTriggerEnter/OnTriggerExit，但它给我错误。
我尝试使用碰撞矩阵，但问题依然存在，尽管它有效，但玩家仍然可以穿过墙壁。

I have a feature in my game were it requires the player to go through walls to slove the puzzle i want the player to only go through the wall that has the tag Puzzle Wall ONLY once then it will no longer work (become a normal wall) after the time end
How can i make it work (you can write a new code since mine has 2 errors )
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Walls : MonoBehaviour
{
// This script is for every wall in the game there is 5 types of walls
private BoxCollider boxCollider;
void Start()
{
Puzzle.OnPuzzleSolved += ActivateWall("Puzzle Wall"); // why do i get this error
boxCollider = GetComponent<BoxCollider>();
}
void Update()
{
}
private void OnTriggerExit(Collider other)
{
boxCollider.isTrigger = false;
}
private void ActivateWall(string wallTypeToActivate)
{
if (wallTypeToActivate == "Puzzle Wall")
{
boxCollider.isTrigger = true;
}
else if (wallTypeToActivate
== " Fake Wall")
{
boxCollider.isTrigger = true;
}
else if (wallTypeToActivate
== "Puzzle Door")
{
boxCollider.isTrigger = true;
}
else
{
boxCollider.isTrigger
= false;
}
}
}
Error 1 i cant pass anything into my action
Error 2 null refrence execption
Error 3 player can go through all walls
I tried to use the on trigger enter / exist but it give me error
I tried using the collison matrix same issue it works but player still can go through it

我重构了你的代码并修复了错误。
在检视器中确保计时器值大于0。
using System.Collections;
using UnityEngine;
public class Walls : MonoBehaviour
{
[SerializeField] private float time;
// This script is for every wall in the game there are 5 types of walls
private BoxCollider boxCollider;
void Start()
{
boxCollider = GetComponent<BoxCollider>();
Puzzle.OnPuzzleSolved += ActivateWall;
}
private void OnDisable()
{
Puzzle.OnPuzzleSolved -= ActivateWall;
}
private void Update()
{
}
private void OnTriggerExit(Collider other)
{
switch (gameObject.tag)
{
// If the tag matches, we disable the collider on exit so the player can't go back
case "Puzzle Wall":
boxCollider.isTrigger = false;
gameObject.GetComponent<Walls>().enabled = false;
break;
case "Fake Wall":
boxCollider.isTrigger = true;
break;
case "Puzzle Door":
boxCollider.isTrigger = true;
break;
}
}
private void ActivateWall()
{
boxCollider.isTrigger = true;
StartCoroutine(StartTimer());
}
IEnumerator StartTimer()
{
yield return new WaitForSeconds(time);
boxCollider.isTrigger = false;
}
}
英文:
I refactored your code and fixed the errors
add a tag with the same name (case sensitive)
in the inspector make sure the timer value is > 0
using System.Collections;
using UnityEngine;
public class Walls : MonoBehaviour
{
[SerializeField] private float time;
// This script is for every wall in the game there is 5 types of walls
private BoxCollider boxCollider;
void Start()
{
boxCollider = GetComponent<BoxCollider>();
Puzzle.OnPuzzleSolved += ActivateWall;
}
private void OnDisable()
{
Puzzle.OnPuzzleSolved -= ActivateWall;
}
private void Update()
{
}
private void OnTriggerExit(Collider other)
{
switch (gameObject.tag)
{
// if the tag matches We disable the collider on exit so
the player can't go back
case "Puzzle Wall":
boxCollider.isTrigger = false;
gameObject.GetComponent<Walls>().enabled = false;
break;
case "Fake Wall":
boxCollider.isTrigger = true;
break;
case "Puzzle Door":
boxCollider.isTrigger = true;
break;
}
}
private void ActivateWall()
{
boxCollider.isTrigger = true;
StartCoroutine(StartTimer());
}
IEnumerator StartTimer()
{
yield return new WaitForSeconds(time);
boxCollider.isTrigger = false;
}
}
