一、前言
经过粗略地分工，在FPS游戏多人化的部分，由我来完成pun控制输入同步和remote开枪效果同步。
二、pun控制输入同步
首先要对游戏角色的物体进行一些组件和脚本的装载。
对于脚本FPCharacterControllerMovement4，它实现了人物移动的网络同步。
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Serialization;
public class FPCharacterControllerMovement4 : MonoBehaviour
{
private CharacterController characterController;
[SerializeField] private Animator characterAnimator;
[SerializeField] private Animator tp_CharacterAnimator;
private Vector3 movementDirection;
private Transform characterTransform;
private float velocity;
private bool isCrouched;
private float originHeight;
public float SprintingSpeed;
public float WalkSpeed;
public float SprintingSpeedWhenCrouched;
public float WalkSpeedWhenCrouched;
public float Gravity = 9.8f;
public float JumpHeight;
public float CrouchHeight = 1f;
public float CurrentSpeed {
get; private set; }
private IEnumerator crouchCoroutine;
private void Start()
{
characterController = GetComponent<CharacterController>();
// characterAnimator = GetComponentInChildren<Animator>();
characterTransform = transform;
originHeight = characterController.height;
}
private void Update()
{
CurrentSpeed = WalkSpeed;
if (characterController.isGrounded)
{
var tmp_Horizontal = Input.GetAxis("Horizontal");
var tmp_Vertical = Input.GetAxis("Vertical");
movementDirection =
characterTransform.TransformDirection(new Vector3(tmp_Horizontal, 0, tmp_Vertical)).normalized;
if (isCrouched)
{
CurrentSpeed = Input.GetKey(KeyCode.LeftShift) ? SprintingSpeedWhenCrouched : WalkSpeedWhenCrouched;
}
else
{
CurrentSpeed = Input.GetKey(KeyCode.LeftShift) ? SprintingSpeed : WalkSpeed;
}
if (Input.GetButtonDown("Jump"))
{
movementDirection.y = JumpHeight;
}
if (Input.GetKeyDown(KeyCode.C))
{
var tmp_CurrentHeight = isCrouched ? originHeight : CrouchHeight;
if (crouchCoroutine != null)
{
StopCoroutine(crouchCoroutine);
crouchCoroutine = null;
}
crouchCoroutine = DoCrouch(tmp_CurrentHeight);
StartCoroutine(crouchCoroutine);
isCrouched = !isCrouched;
}
if (characterAnimator != null)
{
characterAnimator.SetFloat("Velocity",
CurrentSpeed * movementDirection.normalized.magnitude,
0.25f,
Time.deltaTime);
tp_CharacterAnimator.SetFloat("Velocity",
CurrentSpeed * movementDirection.normalized.magnitude,
0.25f,
Time.deltaTime);
tp_CharacterAnimator.SetFloat("Movement_X", tmp_Horizontal, 0.25f, Time.deltaTime);
tp_CharacterAnimator.SetFloat("Movement_Y", tmp_Vertical, 0.25f, Time.deltaTime);
}
}
movementDirection.y -= Gravity * Time.deltaTime;
var tmp_Movement = CurrentSpeed * Time.deltaTime * movementDirection;
characterController.Move(tmp_Movement);
}
private IEnumerator DoCrouch(float _target)
{
float tmp_CurrentHeight = 0;
while (Mathf.Abs(characterController.height - _target) > 0.1f)
{
yield return null;
characterController.height =
Mathf.SmoothDamp(characterController.height, _target,
ref tmp_CurrentHeight, Time.deltaTime * 5);
}
}
internal void SetupAnimator(Animator _animator)
{
Debug.Log($"Execute! the animator is empty??? {
_animator == null}");
characterAnimator = _animator;
}
}
其中，动画设置如图所示。
三、remote开枪效果
主要是在WeaponManager脚本中进行了开枪效果的同步。需要进行Photon.Pun以及PunGame.Scripts.Items的引用。
using System;
using System.Collections;
using System.Collections.Generic;
using Photon.Pun;
using PunGame.Scripts.Items;
using UnityEngine;
using UnityEngine.UI;

private void UpdateAmmoInfo(int _ammo, int _remaningAmmo)
{
if (AmmoCountTextLabel)
AmmoCountTextLabel.text = _ammo + "/" + _remaningAmmo;
}
private void Start()
{
//......
// AmmoCountTextLabel = ;
AmmoCountTextLabel = GameObject.Find("UI").transform.GetChild(6).GetComponent<Text>();
//photonView = GetComponent<PhotonView>();
Debug.Log($"Current weapon is null? {
carriedWeapon == null}");
MainWeapon = photonView.IsMine ? WeaponInfos[0].FP_Weapon : WeaponInfos[0].TP_Weapon;
if (MainWeapon)
{
carriedWeapon = MainWeapon;
CharacterControllerMovement.SetupAnimator(carriedWeapon.GunAnimator);
}
}
private void Update()
{

{

photonView.RPC("RPC_HoldTrigger", RpcTarget.All);
}
if (Input.GetMouseButtonUp(0))
{

// carriedWeapon.ReleaseTrigger();
photonView.RPC("RPC_ReleaseTrigger", RpcTarget.All);
}
if (Input.GetKeyDown(KeyCode.R))

}
