游戲內容要求：
1.靶對象為 5 環，按環計分；
2.箭對象，射中后要插在靶上
- 增強要求：射中后，箭對象產生顫抖效果，到下一次射擊 或 1秒以后
3.游戲僅一輪，無限 trials；
游戲設計：
預制件構建
-
弓
-
靶
- T1
- T2：和T1一樣，只是scale的x和z改成2
- T3：和T1一樣，只是scale的x和z改成1.5
- T4：和T1一樣，只是scale的x和z改成1
- T5：和T1一樣，只是scale的x和z改成0.5
值得一提的是，材質交替使用深色和淺色木紋更好看！

代碼
- SSDirector：導演類，前面幾次作業用過很多次
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class SSDirector : System.Object
{private static SSDirector _instance;public ISceneController CurrentScenceController { get; set; }public static SSDirector GetInstance(){if (_instance == null){_instance = new SSDirector();}return _instance;}
}
- ArrowFactory ：收發箭，跟飛碟游戲里的差不多
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ArrowFactory : MonoBehaviour
{private GameObject arrow = null;private GameObject AB = null;private List<GameObject> usingArrowList = new List<GameObject>();private Queue<GameObject> unusedArrowList = new Queue<GameObject>();public Controllor sceneControler;public void initiate(GameObject AB_){AB = AB_;}public GameObject GetArrow(){//還原工廠AB.transform.SetPositionAndRotation(new Vector3(0, 0, 0), Quaternion.Euler(0, 90, 0));AB.transform.localScale = new Vector3(1, 1, 1);if (unusedArrowList.Count == 0){arrow = Instantiate(Resources.Load<GameObject>("Prefabs/Arrow"));}else{arrow = unusedArrowList.Dequeue();arrow.gameObject.SetActive(true);}arrow.transform.parent = AB.transform;//將弓箭作為AB的子物體arrow.transform.position = new Vector3(0, 0, 0);arrow.transform.rotation = Quaternion.Euler(0, 0, 0);usingArrowList.Add(arrow);return arrow;}public void FreeArrow(){for (int i = 0; i < usingArrowList.Count; i++){if (usingArrowList[i].transform.position.y <= -7 || usingArrowList[i].transform.position.y >= 7){usingArrowList[i].GetComponent<Rigidbody>().isKinematic = true;usingArrowList[i].SetActive(false);usingArrowList[i].transform.position = new Vector3(0, 0, 0);unusedArrowList.Enqueue(usingArrowList[i]);usingArrowList.Remove(usingArrowList[i]);i--;}}}
}
- Controllor ：這里借鑒了師兄的風控代碼，重點是弓箭的繞軸旋轉、運動和碰撞
- MoveBow函數讓弓箭繞交點隨著鼠標的位置反方向擾動，這也是符合我們實際操作弓箭的動作
- Shoot函數為Arrow添加力，在物理引擎的帶動下弓箭仿真運動
using System.Collections;
using System.Collections.Generic;

- ArrowCollider ：這里主要是借鑒了師兄的代碼，學會了能夠使箭射中靶后停留在靶上的方法，我自己確實沒想出來
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ArrowCollider : MonoBehaviour
{public Controllor scene_controller;public scoreRecorder recorder;void Start(){scene_controller = SSDirector.GetInstance().CurrentScenceController as Controllor;recorder = singleton<scoreRecorder>.Instance;}void OnTriggerEnter(Collider c){if (c.gameObject.name == "T1" || c.gameObject.name == "T2" || c.gameObject.name == "T3" || c.gameObject.name == "T4" || c.gameObject.name == "T5"){gameObject.transform.parent.gameObject.GetComponent<Rigidbody>().isKinematic = true;gameObject.SetActive(false);//Debug.Log(this.gameObject.transform.position.x);//Debug.Log(this.gameObject.transform.position.y);float dis = Mathf.Sqrt(this.gameObject.transform.position.x * this.gameObject.transform.position.x + this.gameObject.transform.position.y * this.gameObject.transform.position.y);//Debug.Log("dis"+dis.ToString());float point = 0;if (dis >= 0 && dis < 0.5) point = 4f;else if(dis >= 0.5 && dis < 1) point = 3f;else if(dis >= 1 && dis < 1.5) point = 2f;else if(dis >= 1.5 && dis < 2) point = 1f;else if(dis >= 2 && dis < 2.5) point = 0f;recorder.Record((int)Mathf.Floor(point));}}

- scoreRecorder：記錄分數，離中心的距離越近分數越高

使用的免費Asset：
- Fantasy Skybox FREE：常用天空盒
- Low Poly RPG Fantasy Weapons Lite：弓箭
- Military target：靶（這個我沒有用，不過做出來應該不錯）
