主要理解 协程的应用.

注意 class  TankManager的 [Serializable]属性，才能显示到 Inspector上面。

[HideInInspector] 表示的属性，只能脚本调用。

using System;using UnityEngine;[Serializable]public class TankManager{    public Color m_PlayerColor;                public Transform m_SpawnPoint;             [HideInInspector] public int m_PlayerNumber;                 [HideInInspector] public string m_ColoredPlayerText;    [HideInInspector] public GameObject m_Instance;              [HideInInspector] public int m_Wins;                         private TankMovement m_Movement;           private TankShooting m_Shooting;    private GameObject m_CanvasGameObject;    public void Setup()    {        m_Movement = m_Instance.GetComponent<TankMovement>();        m_Shooting = m_Instance.GetComponent<TankShooting>();        m_CanvasGameObject = m_Instance.GetComponentInChildren<Canvas>().gameObject;        m_Movement.m_PlayerNumber = m_PlayerNumber;        m_Shooting.m_PlayerNumber = m_PlayerNumber;        m_ColoredPlayerText = "<color=#" + ColorUtility.ToHtmlStringRGB(m_PlayerColor) + ">PLAYER " + m_PlayerNumber + "</color>";        MeshRenderer[] renderers = m_Instance.GetComponentsInChildren<MeshRenderer>();        for (int i = 0; i < renderers.Length; i++)        {            renderers[i].material.color = m_PlayerColor;        }    }    public void DisableControl()    {        m_Movement.enabled = false;        m_Shooting.enabled = false;        m_CanvasGameObject.SetActive(false);    }    public void EnableControl()    {        m_Movement.enabled = true;        m_Shooting.enabled = true;        m_CanvasGameObject.SetActive(true);    }    public void Reset()    {        m_Instance.transform.position = m_SpawnPoint.position;        m_Instance.transform.rotation = m_SpawnPoint.rotation;        m_Instance.SetActive(false);        m_Instance.SetActive(true);    }}

GameManager中 应用了协程 Coroutines 控制游戏流程：

using UnityEngine;using System.Collections;using UnityEngine.SceneManagement;using UnityEngine.UI;public class GameManager : MonoBehaviour{    public int m_NumRoundsToWin = 5;            public float m_StartDelay = 3f;             public float m_EndDelay = 3f;               public CameraControl m_CameraControl;       public Text m_MessageText;                  public GameObject m_TankPrefab;             public TankManager[] m_Tanks;               private int m_RoundNumber;                  private WaitForSeconds m_StartWait;         private WaitForSeconds m_EndWait;           private TankManager m_RoundWinner;    private TankManager m_GameWinner;           private void Start()    {        m_StartWait = new WaitForSeconds(m_StartDelay);        m_EndWait = new WaitForSeconds(m_EndDelay);        SpawnAllTanks();        SetCameraTargets();        StartCoroutine(GameLoop());    }    private void SpawnAllTanks()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            m_Tanks[i].m_Instance =                Instantiate(m_TankPrefab, m_Tanks[i].m_SpawnPoint.position, m_Tanks[i].m_SpawnPoint.rotation) as GameObject;            m_Tanks[i].m_PlayerNumber = i + 1;            m_Tanks[i].Setup();        }    }    private void SetCameraTargets()    {        Transform[] targets = new Transform[m_Tanks.Length];        for (int i = 0; i < targets.Length; i++)        {            targets[i] = m_Tanks[i].m_Instance.transform;        }        m_CameraControl.m_Targets = targets;    }    private IEnumerator GameLoop()    {        yield return StartCoroutine(RoundStarting());        yield return StartCoroutine(RoundPlaying());        yield return StartCoroutine(RoundEnding());       if (m_GameWinner != null)        {            SceneManager.LoadScene(0);        }        else        {            StartCoroutine(GameLoop());        }    }    private IEnumerator RoundStarting()    {        // As soon as the round starts reset the tanks and make sure they can't move.        ResetAllTanks();        DisableTankControl();        // Snap the camera's zoom and position to something appropriate for the reset tanks.        m_CameraControl.SetStartPositionAndSize();        // Increment the round number and display text showing the players what round it is.        m_RoundNumber++;        m_MessageText.text = "ROUND " + m_RoundNumber;        // Wait for the specified length of time until yielding control back to the game loop.        yield return m_StartWait;    }    private IEnumerator RoundPlaying()    {        EnableTankControl ();            // Clear the text from the screen.            m_MessageText.text = string.Empty;            // While there is not one tank left...            while (!OneTankLeft())            {                // ... return on the next frame.                yield return null;            }    }    private IEnumerator RoundEnding()    {        // Stop tanks from moving.        DisableTankControl();        // Clear the winner from the previous round.        m_RoundWinner = null;        // See if there is a winner now the round is over.        m_RoundWinner = GetRoundWinner();        // If there is a winner, increment their score.        if (m_RoundWinner != null)            m_RoundWinner.m_Wins++;        // Now the winner's score has been incremented, see if someone has one the game.        m_GameWinner = GetGameWinner();        // Get a message based on the scores and whether or not there is a game winner and display it.        string message = EndMessage();        m_MessageText.text = message;        // Wait for the specified length of time until yielding control back to the game loop.        yield return m_EndWait;    }    private bool OneTankLeft()    {        int numTanksLeft = 0;        for (int i = 0; i < m_Tanks.Length; i++)        {            if (m_Tanks[i].m_Instance.activeSelf)                numTanksLeft++;        }        return numTanksLeft <= 1;    }    private TankManager GetRoundWinner()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            if (m_Tanks[i].m_Instance.activeSelf)                return m_Tanks[i];        }        return null;    }    private TankManager GetGameWinner()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            if (m_Tanks[i].m_Wins == m_NumRoundsToWin)                return m_Tanks[i];        }        return null;    }    private string EndMessage()    {        string message = "DRAW!";        if (m_RoundWinner != null)            message = m_RoundWinner.m_ColoredPlayerText + " WINS THE ROUND!";        message += "\n\n\n\n";        for (int i = 0; i < m_Tanks.Length; i++)        {            message += m_Tanks[i].m_ColoredPlayerText + ": " + m_Tanks[i].m_Wins + " WINS\n";        }        if (m_GameWinner != null)            message = m_GameWinner.m_ColoredPlayerText + " WINS THE GAME!";        return message;    }    private void ResetAllTanks()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            m_Tanks[i].Reset();        }    }    private void EnableTankControl()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            m_Tanks[i].EnableControl();        }    }    private void DisableTankControl()    {        for (int i = 0; i < m_Tanks.Length; i++)        {            m_Tanks[i].DisableControl();        }    }}
