游戏对象使用小结:

  1. 常见游戏对象有空对象,摄像机,光线,天空盒,地形,3D对象,声音,UI系统和粒子系统以及特效。
  2. 游戏对象均具有Active,Name,Tag,Layer属性。
  3. 根据游戏场景氛围的不同,可以改变光源类型来烘托场景气氛。

游戏组织结构:

这次与基础版的区别主要是实现动作分离,上一次的动作是由专门的类来完成的,并且每个对象各自管理一部分自己的移动属性。这次将这些动作管理分离出来,实现动作和物体属性的分离。

  • SSAction类:SSAction是所有动作的基类,ScriptableObject 是不需要绑定 GameObject 对象的可编程基类。
    public class SSAction : ScriptableObject 
    {

        public bool enable = true;
        public bool destroy = false;

        public GameObject gameObject;
        public Transform transform;
        public SSActionCallback CallBack;

        public virtual void Start()
        {
            throw new System.NotImplementedException();
        }

        public virtual void Update()
        {
            throw new System.NotImplementedException();
        }
    }

  • CCMoveToAction类:实现简单的动作,并且管理内存回收以及重写Update()函数实现物体的运动。
public class CCMoveToAction : SSAction
{
    public Vector3 target;
    public float speed;

    private CCMoveToAction() { }
    public static CCMoveToAction getAction(Vector3 target, float speed)
    {
        CCMoveToAction action = ScriptableObject.CreateInstance();
        action.target = target;
        action.speed = speed;
        return action;
    }

    public override void Update()
    {
        this.transform.position = Vector3.MoveTowards(transform.position, target, speed * Time.deltaTime);
        if (transform.position == target)
        {
            destroy = true;
            CallBack.SSActionCallback(this);
        }
    }

    public override void Start()
    {
        
    }
}

  • CCSequenceAction类:创建动作执行序列,按要求循环执行保存的动作序列。
public class CCSequenceAction : SSAction
{
    public List sequence;
    public int repeat = 1; // 1->only do it for once, -1->repeat forever
    public int currentActionIndex = 0;

    public static CCSequenceAction getAction(int repeat, int currentActionIndex, List sequence)
    {
        CCSequenceAction action = ScriptableObject.CreateInstance();
        action.sequence = sequence;
        action.repeat = repeat;
        action.currentActionIndex = currentActionIndex;
        return action;
    }

    public override void Update()
    {
        if (sequence.Count == 0) return;
        if (currentActionIndex < sequence.Count)
        {
            sequence[currentActionIndex].Update();
        }
    }

    public void SSActionCallback(SSAction source)
    {
        source.destroy = false;
        this.currentActionIndex++;
        if (this.currentActionIndex >= sequence.Count)
        {
            this.currentActionIndex = 0;
            if (repeat > 0) repeat--;
            if (repeat == 0)
            {
                this.destroy = true;
                this.CallBack.SSActionCallback(this);
            }
        }
    }

    public override void Start()
    {
        foreach (SSAction action in sequence)
        {
            action.gameObject = this.gameObject;
            action.transform = this.transform;
            action.CallBack = this;
            action.Start();
        }
    }

    void OnDestroy()
    {
        foreach (SSAction action in sequence)
        {
            DestroyObject(action);
        }
    }
}

  • SSActionCallback接口:定义了事件处理接口,所有事件管理者都必须实现这个接口来实现事件调度。
public interface SSActionCallback
{
    void SSActionCallback(SSAction source);
}

  • SSActionManager类:动作管理的基类,使用上述的移动方法,实现游戏对象与动作的绑定,确定回调函数消息的接收对象。
public class SSActionManager : MonoBehaviour
{
    private Dictionary actions = new Dictionary();
    private List waitingToAdd = new List();
    private List watingToDelete = new List();

    protected void Update()
    {
        foreach (SSAction ac in waitingToAdd)
        {
            actions[ac.GetInstanceID()] = ac;
        }
        waitingToAdd.Clear();

        foreach (KeyValuePair kv in actions)
        {
            SSAction ac = kv.Value;
            if (ac.destroy)
            {
                watingToDelete.Add(ac.GetInstanceID());
            }
            else if (ac.enable)
            {
                ac.Update();
            }
        }

        foreach (int key in watingToDelete)
        {
            SSAction ac = actions[key];
            actions.Remove(key);
            DestroyObject(ac);
        }
        watingToDelete.Clear();
    }

    public void addAction(GameObject gameObject, SSAction action, SSActionCallback ICallBack)
    {
        action.gameObject = gameObject;
        action.transform = gameObject.transform;
        action.CallBack = ICallBack;
        waitingToAdd.Add(action);
        action.Start();
    }
}
  • FirstSceneActionManager类:当前场景下的动作管理的具体实现,与场景控制基类配合,实现对当前场景的直接管理。挂载到图像中的Main空对象上实现对预制加载的场景的管理。
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Interfaces;

public class FirstSceneActionManager : SSActionManager, SSActionCallback
{
    public SSActionEventType Complete = SSActionEventType.Completed;

    public void BoatMove(BoatController Boat)
    {
        Complete = SSActionEventType.Started;
        CCMoveToAction action = CCMoveToAction.getAction(Boat.GetDestination(), Boat.GetMoveSpeed());
        addAction(Boat.GetGameObject(), action, this);
        Boat.ChangeState();
    }

    public void GameObjectsMove(GameObjects GameObject, Vector3 Destination)
    {
        Complete = SSActionEventType.Started;
        Vector3 CurrentPos = GameObject.GetPosition();
        Vector3 MiddlePos = CurrentPos;
        if (Destination.y > CurrentPos.y)
        {
            MiddlePos.y = Destination.y;
        }
        else
        {
            MiddlePos.x = Destination.x;
        }
        SSAction action1 = CCMoveToAction.getAction(MiddlePos, GameObject.GetMoveSpeed());
        SSAction action2 = CCMoveToAction.getAction(Destination, GameObject.GetMoveSpeed());
        SSAction seqAction = CCSequenceAction.getAction(1, 0, new List { action1, action2 });
        this.addAction(GameObject.GetGameobject(), seqAction, this);
    }

    public void SSActionCallback(SSAction source)
    {
        Complete = SSActionEventType.Completed;
    }
}
