unity3D 作業5 物理版打飛碟

物理版打飛碟遊戲

這一次實現的是物理版的打飛碟遊戲，這一次和上一次的區別在於這一次增加了一個PhysicAction和PhysicsActionManager的類，PhysicAction專門來負責完成物理運動，Manager就專門來負責完成其管理了。

第一步，首先給物體加上剛體的屬性。

第二步，我們增加PhysicAction，這一步其實和之前的CCAction沒有什麼區別，主要的差別就在於這裏不再確定地點了，畢竟我們負責把碟子丟出去，然後剩下的就依靠引力來解決這個問題了，代碼如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PhysicAction : SSAction
{
    public Vector3 speed;

    public static PhysicAction GetSSAction()
    {
        PhysicAction action = CreateInstance<PhysicAction>();
        return action;
    }

    public override void Start(){
    }
    public override void Update(){
        if (transform.position.y < -10 || transform.position.x <= -20 || transform.position.x >= 20){
            gameObject.GetComponent<Rigidbody>().isKinematic = true;
            gameObject.GetComponent<Rigidbody>().velocity = Vector3.zero;
            transform.position = Vector3.down;
            callback.SSActionEvent(this);
        }
    }
}

第三步，我們增加PhysicsActionManager，這一步其實和之前的manager也相似，當然最大的區別還是在於剛體的區別，這裏我們設定飛碟的速度什麼的就和之前不一樣了。代碼如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PhysicsActionManager : SSActionManager, ISSActionCallback,IActionManager {
    public FirstSceneController sceneController;
    public List<PhysicAction> seq = new List<PhysicAction>();
    public UserClickAction userClickAction;
    public SkeetFactory skeets;
    
    public void Start()
    {
        sceneController = (FirstSceneController)SSDirector.getInstance().currentSceneController;
        sceneController.actionManager = this;
        skeets = Singleton<SkeetFactory>.Instance;
    }
    public void PlaySkeet()
    {
        if(skeets.used.Count > 0)
        {
            GameObject skeet = skeets.used[0];
            float x = Random.Range(-5, 5);
			skeet.transform.GetComponent<Rigidbody>().isKinematic = false;
			skeet.GetComponent<Rigidbody>().velocity = new Vector3(x, 8 * (Mathf.CeilToInt(FirstSceneController.times / 10) + 1) + 2, 6);
            skeet.GetComponent<Rigidbody>().AddForce(new Vector3(0,8.8f, 0),ForceMode.Force);
            PhysicAction physicAction = PhysicAction.GetSSAction();
            seq.Add(physicAction);
            this.RunAction(skeet, physicAction, this);
            skeets.used.RemoveAt(0);
        }
        if (Input.GetMouseButtonDown(0) && sceneController.flag == 0)
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitGameObject;
            if (Physics.Raycast(ray, out hitGameObject))
            {
                GameObject gameObject = hitGameObject.collider.gameObject;
                if (gameObject.tag == "skeet")
                {
					gameObject.transform.position = new Vector3(100,100,100);
					userClickAction = UserClickAction.GetSSAction();
                    this.RunAction(gameObject, userClickAction, this);
                }
            }
        }
        base.Update();
    }
    public void SSActionEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
    {
        skeets.RecycleSkeet(source.gameObject);
        seq.Remove(source as PhysicAction);
        source.destory = true;
        if (FirstSceneController.times >= 30)
            sceneController.flag = 1;
    }
    public void CheckEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
    {
    }    
	public void Pause(){
        if (sceneController.flag == 0){
            foreach (var k in seq)
            {
                k.speed = k.transform.GetComponent<Rigidbody>().velocity;
                k.transform.GetComponent<Rigidbody>().isKinematic = true;
            }
            sceneController.flag = 2;
        }
        else if (sceneController.flag == 2){
            foreach (var k in seq)
            {
                k.transform.GetComponent<Rigidbody>().isKinematic = false;
                k.transform.GetComponent<Rigidbody>().velocity = k.speed;
            }
            sceneController.flag = 0;
        }
    }
}

第四步，我們增加IActionManager接口，主要要求實現PlaySkeet和Pause，畢竟這一個和之前的都不太一樣。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public interface IActionManager {
    void PlaySkeet();
    void Pause();
}

至此完成。
