我正在创建一个游戏，玩家需要在计时器用尽之前杀死特定数量的敌人。如果玩家没有杀死他打算杀死的敌人数量，并且计时器耗尽，他将被带到失败现场。我的问题是，即使计时器用尽并且不能杀死所需数量的敌人，他也不会被带到失败现场。我该如何解决？
EnemySpawner脚本：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class EnemySpawner : MonoBehaviour {
[SerializeField] GameObject EnemyPreFab;
[SerializeField] int MaxEnemies = 30;
[SerializeField] float EnemySpawnTime = 1.00001f;
[SerializeField] GameObject FirstWaypoint;
int CurrentNumOfEnemies = 0;
int EnemiesToNextLevel = 7;
int KilledEnemies = 0;
public LevelManager myLevelManager;
public static EnemySpawner Instance = null;
int timesEnemyHit;
IEnumerator SpawningEnemies()
{
while(CurrentNumOfEnemies <= MaxEnemies)
{
GameObject Enemy = Instantiate(EnemyPreFab, this.transform.position, Quaternion.identity);
CurrentNumOfEnemies++;
yield return new WaitForSeconds(EnemySpawnTime);
}
}
void Start()
{
if (Instance == null)
Instance = this;
StartCoroutine(SpawningEnemies());
timesEnemyHit = 0;
if (this.gameObject.tag == "EnemyHit")
{
CurrentNumOfEnemies++;
}
}
public void OnEnemyDeath()
{
/* CurrentNumOfEnemies--;
if (CurrentNumOfEnemies < 5)
{
// You killed everyone, change scene:
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
/* KilledEnemies++;
if (KilledEnemies >= EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
if(Time.timer == 0.0f && KilledEnemies != EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("Lose");
}
}
}
计时器脚本：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Timer : MonoBehaviour
{
public Text TimerText;
public float MainTime;
public static float timer;
public bool CanCount = true;
public bool OnlyOnce = false;
void Start()
{
timer = MainTime; //Timer is gonna be equal to what we set MainTime in the inspector
}
void Update()
{
if (timer >= 0.0f && CanCount)
{
timer -= Time.deltaTime;//The timer will count down in delta time based on the seconds we have
TimerText.text = timer.ToString("F");//Converting Timer into a string value
}
//This means that when the timer reaches zero and OnlyOnce is equal to false
else if (timer <= 0.0f && !OnlyOnce) //If the timer goes below 0 and OnlyOnce is not equal to flase
{
CanCount = false; //CanCount is equal to false so we are not counting down anymore since it's not greater than zero and we can't count anymore
OnlyOnce = true; //This is goning to be done once when it reaches it
TimerText.text = "0.00"; //Setting the UI to 0
timer = 0.0f; //Setting the timer to 0
}
}
}

使用当前代码结构：您的敌人生成者可以将EnemyKilled和EnemiesToNextLevel变量作为公共变量。并且，您可以在计时器脚本中使用EnemySpawner的Instance变量。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class EnemySpawner : MonoBehaviour {
[SerializeField] GameObject EnemyPreFab;
[SerializeField] int MaxEnemies = 30;
[SerializeField] float EnemySpawnTime = 1.00001f;
[SerializeField] GameObject FirstWaypoint;
int CurrentNumOfEnemies = 0;
public int EnemiesToNextLevel = 7;
public int KilledEnemies = 0;
public LevelManager myLevelManager;
public static EnemySpawner Instance = null;
int timesEnemyHit;
IEnumerator SpawningEnemies()
{
while(CurrentNumOfEnemies <= MaxEnemies)
{
GameObject Enemy = Instantiate(EnemyPreFab, this.transform.position, Quaternion.identity);
CurrentNumOfEnemies++;
yield return new WaitForSeconds(EnemySpawnTime);
}
}
void Start()
{
if (Instance == null)
Instance = this;
StartCoroutine(SpawningEnemies());
timesEnemyHit = 0;
if (this.gameObject.tag == "EnemyHit")
{
CurrentNumOfEnemies++;
}
}
public void OnEnemyDeath()
{
CurrentNumOfEnemies--;
/*
if (CurrentNumOfEnemies < 5)
{
// You killed everyone, change scene:
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
KilledEnemies++;
if (Time.timer > 0 && KilledEnemies >= EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("NextLevelMenu");
}
}
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Timer : MonoBehaviour
{
public Text TimerText;
public float MainTime;
public static float timer;
public bool CanCount = true;
public bool OnlyOnce = false;
void Start()
{
timer = MainTime; //Timer is gonna be equal to what we set MainTime in the inspector
}
void Update()
{
if (timer >= 0.0f && CanCount)
{
timer -= Time.deltaTime;//The timer will count down in delta time based on the seconds we have
TimerText.text = timer.ToString("F");//Converting Timer into a string value
}
//This means that when the timer reaches zero and OnlyOnce is equal to false
else if (timer <= 0.0f && !OnlyOnce) //If the timer goes below 0 and OnlyOnce is not equal to flase
{
CanCount = false; //CanCount is equal to false so we are not counting down anymore since it's not greater than zero and we can't count anymore
OnlyOnce = true; //This is goning to be done once when it reaches it
TimerText.text = "0.00"; //Setting the UI to 0
timer = 0.0f; //Setting the timer to 0
if(Time.timer == 0.0f && EnemySpawner.Instance.KilledEnemies != EnemySpawner.Instance.EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("Lose");
}
}
}
}
PS：可以改进代码。让我知道是否有帮助。

在计时器的更新功能中
void Update()
{
if (timer >= 0.0f && CanCount)
{
timer -= Time.deltaTime;//The timer will count down in delta time based on the seconds we have
TimerText.text = timer.ToString("F");//Converting Timer into a string value
}
//This means that when the timer reaches zero and OnlyOnce is equal to false
else if (timer <= 0.0f && !OnlyOnce) //If the timer goes below 0 and OnlyOnce is not equal to flase
{
CanCount = false; //CanCount is equal to false so we are not counting down anymore since it's not greater than zero and we can't count anymore
OnlyOnce = true; //This is goning to be done once when it reaches it
TimerText.text = "0.00"; //Setting the UI to 0
timer = 0.0f; //Setting the timer to 0
EnemySpawner.timeIsZero = true;
}
}
}
然后在您的EnemySpawner脚本中添加一个公共的静态布尔timeIsZero = false;。在顶部，然后在
public void OnEnemyDeath()
{
/* CurrentNumOfEnemies--;
if (CurrentNumOfEnemies < 5)
{
// You killed everyone, change scene:
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
/* KilledEnemies++;
if (KilledEnemies >= EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("NextLevelMenu");
}
*/
if(timeIsZero && KilledEnemies != EnemiesToNextLevel)
{
LaserLevelManager.LoadLevel("Lose");
}
}
}
