c# - 你如何在 C# 中制作向玩家射击的光线投射?
问题描述
我一直在尝试做一个 fps 游戏并且卡在敌人可以射击玩家的部分,我不太确定我能做什么。敌人继续漫游,而不是实际攻击玩家。更糟糕的是,他们有时会远离玩家。有人可以帮忙吗?
using UnityEngine;
using UnityEngine.AI;
public class EnemyAI : MonoBehaviour
{
public NavMeshAgent NavAgent;
public Transform Player;
public LayerMask GroundCheck, PlayerCheck;
public Transform EnemyPrototype;
public float range;
public float Damage;
public Vector3 WalkPoint; // Code for patrolling Around
bool WalkPointSet;
public float WalkPointRange;
public float SightRange, AttackRange; // Code for checking when to engage in a firefight with the player
public bool PlayerInSight, AttackPlayer;
public float AttackCooldown; // Code for firefights with the player
bool AlreadyAttacked;
private void AIActive()
{
Player = GameObject.Find("Player").transform;
NavAgent = GetComponent<NavMeshAgent>();
}
private void Update()
{
PlayerInSight = Physics.CheckSphere(transform.position, SightRange, PlayerCheck);
AttackPlayer = Physics.CheckSphere(transform.position, AttackRange, PlayerCheck);
if (!PlayerInSight && !AttackPlayer)
{
Patrol();
}
if (PlayerInSight && !AttackPlayer)
{
Engage();
}
if (PlayerInSight && AttackPlayer)
{
FireAtPlayer();
}
}
private void Patrol() // The enemy will move in order to try and find the player
{
if (!WalkPointSet)
{
SearchWalkPoint();
}
if (WalkPointSet)
{
NavAgent.SetDestination(WalkPoint);
}
Vector3 WalkPointDistance = transform.position - WalkPoint;
if (WalkPointDistance.magnitude < 1f)
{
WalkPointSet = false;
}
}
private void SearchWalkPoint() // Makes a random point where the enemy would patrol
{
float WalkZ = Random.Range(-WalkPointRange, WalkPointRange);
float WalkX = Random.Range(-WalkPointRange, WalkPointRange);
WalkPoint = new Vector3(transform.position.x + WalkX, transform.position.y, transform.position.z + WalkZ);
if (Physics.Raycast(WalkPoint, -transform.up, 2f, GroundCheck))
{
WalkPointSet = true;
}
}
private void Engage() // The enemy has found the player and will move towards them to get a better shot
{
NavAgent.SetDestination(Player.position);
}
private void FireAtPlayer() // The enemy will now try to get a shot on the player
{
NavAgent.SetDestination(transform.position);
transform.LookAt(Player);
if (!AlreadyAttacked)
{
RaycastHit Hit;
if (Physics.Raycast(EnemyPrototype.transform.position, EnemyPrototype.transform.forward, out Hit, range, PlayerCheck))
{
Debug.Log(Hit.collider.name);
Target target = Hit.transform.GetComponent<Target>();
if (target != null)
{
target.TakeDamage(Damage);
}
}
AlreadyAttacked = true;
Invoke(nameof(AttackReset), AttackCooldown);
}
}
private void AttackReset()
{
AlreadyAttacked = false;
}
}
我不知道问题是巡逻还是实际的射击代码,因为我对 C# 很陌生,并且主要使用互联网上的教程来帮助我,但这次我不知道去哪里
