Unity3D学习（四）射箭游戏

然后是用rigidbody的处理来实现一个射箭游戏

这里贴上游戏效果和代码

ArrowController.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using game;namespace game {public class ArrowController {GameObject arrow;Vector3 startPos;ArrowScript arrowScript;Vector3 resetForce;public ArrowController(GameObject obj) {arrow = obj;startPos = new Vector3 (0, 0, 0);arrow.transform.position = startPos;arrowScript = obj.AddComponent<ArrowScript> ();obj.AddComponent<MoveAction> ();arrowScript.arrow = this;resetForce = new Vector3 (0, 0, -10);}public GameObject getGameObj() {return arrow;}public void appear() {this.arrow.SetActive (true);}public void disappear() {this.arrow.SetActive (false);}public void setPosition(Vector3 pos) {this.arrow.transform.position = pos;}public Rigidbody getRigidBody() {return arrow.GetComponent<Rigidbody> ();}public void reset() {Debug.Log ("reset...");
//          this.arrow.AddComponent<Rigidbody> ();
//          this.arrow.transform.position = startPos;this.getRigidBody ().AddForce (resetForce);}}
}

ArrowFactory.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using game;namespace game {public class ArrowFactory : MonoBehaviour {Queue<ArrowController> freeQueue;List<ArrowController> usingList;GameObject originalArrow;Vector3 startPos;void Awake() {freeQueue = new Queue<ArrowController> ();usingList = new List<ArrowController> ();originalArrow = Object.Instantiate (Resources.Load ("prefabs/arrow", typeof(GameObject))) as GameObject;
//          originalArrow.AddComponent<BoxCollider> ();originalArrow.AddComponent<OnCollision> ();originalArrow.AddComponent<Rigidbody> ();originalArrow.GetComponent<Rigidbody> ().collisionDetectionMode = CollisionDetectionMode.Continuous;originalArrow.GetComponent<Rigidbody> ().useGravity = false;
//          originalArrow.GetComponent<Collider> ().isTrigger = true;originalArrow.SetActive (false);startPos = new Vector3 (0, 0, 0);}// Use this for initializationvoid Start () {}// Update is called once per framevoid Update () {}public ArrowController produceArrow() {Debug.Log ("producing arrow...");ArrowController newArrow;newArrow = null;if (freeQueue.Count == 0) {GameObject newObj = GameObject.Instantiate (originalArrow);
//              newObj.AddComponent<MoveAction> ();newArrow = new ArrowController (newObj);} else {newArrow = freeQueue.Dequeue ();}newArrow.appear ();
//          newArrow.setPosition (startPos);usingList.Add (newArrow);return newArrow;}public void recycle (ArrowController arrow) {Debug.Log ("recycle in ArrowFactory...");arrow.disappear ();arrow.reset ();arrow.getGameObj ().transform.position = startPos;usingList.Remove (arrow);freeQueue.Enqueue (arrow);}}
}

ArrowScript.cs（也是为了能从GameObject获取到Controller）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using game;namespace game {public class ArrowScript : MonoBehaviour {public ArrowController arrow;// Use this for initializationvoid Start () {for (int i = 0; i < transform.childCount; i++){GameObject g = transform.GetChild(i).gameObject;g.AddComponent<ArrowScript>().arrow = arrow;}}// Update is called once per framevoid Update () {}}
}

Director.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using game;namespace game {public class Director : System.Object {private static Director director;public SceneController currentSceneController;public static Director getInsance() {if (director == null) {director = new Director ();}return director;}}
}

FirstSceneController.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using game;namespace game {public class FirstSceneController : MonoBehaviour, SceneController, userAction {Director director;ArrowController arrow;ArrowFactory af;MoveAction ma;GameObject target;GameObject ground;GameObject wall;Scorer scorer;UserGUI UI;GameObject canvas;Text scoreText;OnCollision oc;
//      TargetController target;// Use this for initializationvoid Awake() {Director director = Director.getInsance ();director.currentSceneController = this;}public void loadResources() {target = GameObject.Instantiate (Resources.Load("prefabs/targetBasis")) as GameObject;
//          target.AddComponent<Rigidbody> ();
//          target.AddComponent<OnCollision> ();
//          target.GetComponentInChildren<Collider> ().isTrigger = true;target.transform.position = new Vector3 (0, 0.3f, 0);ground = GameObject.Instantiate (Resources.Load("prefabs/ground")) as GameObject;wall = GameObject.Instantiate (Resources.Load("prefabs/wall")) as GameObject;}void Start () {loadResources ();af = GetComponent<ArrowFactory> ();ma = GetComponent<MoveAction> ();scorer = GetComponent<Scorer> ();UI = GetComponent<UserGUI> ();oc = GetComponent<OnCollision> ();
//          oc.target = target;canvas = GameObject.Instantiate (Resources.Load("prefabs/Canvas")) as GameObject;scoreText = canvas.transform.Find ("Score").GetComponent<Text> ();scoreText.text = "Score: 0";}// Update is called once per framevoid Update () {scoreText.text = "Score: " + scorer.getScore ();}public void startGame() {Debug.Log ("Game starts...");nextShoot ();}public void OnCollision(GameObject obj) {
//          Debug.Log (obj.GetComponent<MeshRenderer>().material.color);Debug.Log ("The obj name is " + obj.name);scorer.addScore (obj);}public void nextShoot() {arrow = af.produceArrow ();ma = arrow.getGameObj ().GetComponent<MoveAction> ();//testDebug.Log("arrow is " + arrow.ToString());
//          Debug.Log ("judgement: "+ (arrow==null).ToString());ma.setArrow (arrow);Debug.Log ("ma's Arrow is "+arrow.ToString());ma.setShot (false);oc.setFlag (false);
//          nextShoot ();}public void recycle (ArrowController arrow) {
//          ma = arrow.getGameObj ().GetComponent<MoveAction> ();//testDebug.Log ("recycling..." + arrow);if (arrow != null) {af.recycle (arrow);}}}
