塔防篇：Day2

Morning:

上午初步计划：把炮台ui，逻辑部分搞定，begin!

先用UGUI造成一组按钮，然后添加开关组，使得每次需要建设的炮台只有一个可以被选中

效果目前是这样的。之后开始造炮台。

一： 存储炮台数据 

using System.Collections;using System.Collections.Generic;using UnityEngine;[System.Serializable]public class TurretData {public GameObject turretPrefab;public int cost;public GameObject turretUpgradedPrefab;public int costUpgraded;public TurretType type;}public enum TurretType{LaserTurret,MissileTurret,StandardTurret}

二：在GameManager上再次添加建造管理的脚本，保留当前操作选择

在inspector面板中添加监听 

using System.Collections;using System.Collections.Generic;using UnityEngine;public class BuildManager : MonoBehaviour {public TurretData laserTurretData;public TurretData missileTurretData;public TurretData standarTurretData;//当前选择炮台public TurretData selectTurretType;public void OnLaserSelected(bool isOn){Debug.Log (1);if (isOn) {selectTurretType = laserTurretData;}}public void OnMissileSelected(bool isOn){Debug.Log (2);if (isOn)selectTurretType = missileTurretData;}public void OnStandardSelected(bool isOn){Debug.Log (3);if (isOn)selectTurretType = standarTurretData;}}

咯~ 碰到了个新奇错误，上午差点死在这上。。添加完buildTurret脚本 发现开关突然死过去了，点不动了。。调了好一番。

才知道这俩东西是一起的。。 以为事件系统没用，随手一发delete。。这个不能删！！

三：检测鼠标与哪个cube （可以建造炮台的位置）发生射线碰撞

1.先把之前mapcube添加个layer 

2.build添加update鼠标点击内容

public class BuildManager : MonoBehaviour {public TurretData laserTurretData;public TurretData missileTurretData;public TurretData standarTurretData;//当前选择炮台public TurretData selectTurretType;void Update(){if (Input.GetMouseButton(0)) {if(EventSystem.current.IsPointerOverGameObject()==false) //查API得。。。 （若是移动端 要传参){//炮台建造，Cube若是空 若非空Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hit;bool isCollider=Physics.Raycast (ray,out hit,1000,LayerMask.GetMask("MapCube"));if (isCollider) {GameObject mapCube = hit.collider.gameObject;//得到点击的mapCube }}}}//下面和 原来部分相同

3.创建mapCube脚本 挂载在cube上， 目的是使得建立操作分离出来，直接在mapCube上判断

using System.Collections;using System.Collections.Generic;using UnityEngine;public class MapCube : MonoBehaviour {[HideInInspector]public GameObject turretGo;void Start () {} public void BuildTurret(GameObject turretPrefab){}}

4.继续完善build脚本

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.EventSystems;public class BuildManager : MonoBehaviour {public TurretData laserTurretData;public TurretData missileTurretData;public TurretData standarTurretData;public int money=10000;//当前选择炮台public TurretData selectTurretType;void Update(){if (Input.GetMouseButton(0)) {if(EventSystem.current.IsPointerOverGameObject()==false) //查API得。。。 （若是移动端 要传参){//炮台建造，Cube若是空 若非空Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hit;bool isCollider=Physics.Raycast (ray,out hit,1000,LayerMask.GetMask("MapCube"));if (isCollider) {MapCube mapCube = hit.collider.GetComponent<MapCube>();//得到点击的mapCube if (mapCube.turretGo == false) {//可以创建if (money >= selectTurretType.cost) {money -= selectTurretType.cost;mapCube.BuildTurret (selectTurretType.turretPrefab);} else {//提示钱够不够。..。}} else {//升级}}}}}public void OnLaserSelected(bool isOn){Debug.Log (1);if (isOn) {selectTurretType = laserTurretData;}}public void OnMissileSelected(bool isOn){Debug.Log (2);if (isOn)selectTurretType = missileTurretData;}public void OnStandardSelected(bool isOn){Debug.Log (3);if (isOn)selectTurretType = standarTurretData;}}

5. 把钱的组件加上

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.EventSystems;using UnityEngine.UI;public class BuildManager : MonoBehaviour {public TurretData laserTurretData;public TurretData missileTurretData;public TurretData standarTurretData;private int money=10000;public Text moneyText;//当前选择炮台private TurretData selectTurretType;void ChangeMoney(int change=0){money += change;moneyText.text = "￥" + money;}void Update(){if (Input.GetMouseButton(0)) {if(EventSystem.current.IsPointerOverGameObject()==false) //查API得。。。 （若是移动端 要传参){//炮台建造，Cube若是空 若非空Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition); //Debug.Log ("er"); RaycastHit hit;bool isCollider=Physics.Raycast (ray,out hit,1000,LayerMask.GetMask("MapCube"));if (isCollider&&selectTurretType!=null) { MapCube mapCube = hit.collider.GetComponent<MapCube>();//得到点击的mapCube if (mapCube.turretGo == false) {//可以创建if (money >= selectTurretType.cost) {ChangeMoney (-selectTurretType.cost); //mapCube.BuildTurret (selectTurretType.turretPrefab);} else {//提示钱够不够。..。}} else {//升级}}}}}public void OnLaserSelected(bool isOn){ if (isOn) {selectTurretType = laserTurretData;}}public void OnMissileSelected(bool isOn){ if (isOn)selectTurretType = missileTurretData;}public void OnStandardSelected(bool isOn){ if (isOn)selectTurretType = standarTurretData;}}

//遇到问题是。。之前 第一步。。添加射线了。。但是忘记更新layer。 还有个就是要判断当前选择炮台是否为空。

编辑没有钱时候的动画。状态机如图所示

OK 上午结束，附上代码及组件关系，下午继续

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEngine.EventSystems;using UnityEngine.UI;public class BuildManager : MonoBehaviour {public TurretData laserTurretData;public TurretData missileTurretData;public TurretData standarTurretData;private int money=500 ;public Animator moneyAnimator;public Text moneyText;//当前选择炮台private TurretData selectTurretType;void ChangeMoney(int change=0){money += change;moneyText.text = "￥" + money;}void Update(){if (Input.GetMouseButton(0)) {if(EventSystem.current.IsPointerOverGameObject()==false) //查API得。。。 （若是移动端 要传参){//炮台建造，Cube若是空 若非空Ray ray=Camera.main.ScreenPointToRay(Input.mousePosition); //Debug.Log ("er"); RaycastHit hit;bool isCollider=Physics.Raycast (ray,out hit,1000,LayerMask.GetMask("MapCube"));if (isCollider&&selectTurretType!=null) { MapCube mapCube = hit.collider.GetComponent<MapCube>();//得到点击的mapCube if (mapCube.turretGo == false) {//可以创建if (money >= selectTurretType.cost) {ChangeMoney (-selectTurretType.cost); //mapCube.BuildTurret (selectTurretType.turretPrefab);} else {//提示钱够不够。..。moneyAnimator.SetTrigger("Flicker");}} else {//升级}}}}}public void OnLaserSelected(bool isOn){ if (isOn) {selectTurretType = laserTurretData;}}public void OnMissileSelected(bool isOn){ if (isOn)selectTurretType = missileTurretData;}public void OnStandardSelected(bool isOn){ if (isOn)selectTurretType = standarTurretData;}}

afternoon:

准备开始创建炮台！

实例化出来。。就这样。

using System.Collections;using System.Collections.Generic;using UnityEngine;public class MapCube : MonoBehaviour {[HideInInspector]public GameObject turretGo=null;void Start () {} public void BuildTurret(GameObject turretPrefab){turretGo=GameObject.Instantiate (turretPrefab,transform.position,Quaternion.identity);}}

Go On.

做粒子效果， 每次实例炮台时有土飞溅， （就像QQ塔防的小锤子）。。。

效果

把粒子效果做成prefab，然后在建造炮台时直接实例。

using System.Collections;using System.Collections.Generic;using UnityEngine;public class MapCube : MonoBehaviour {[HideInInspector]public GameObject turretGo=null;public GameObject buildEffect;void Start () {} public void BuildTurret(GameObject turretPrefab){turretGo=GameObject.Instantiate (turretPrefab,transform.position,Quaternion.identity);GameObject effect=GameObject.Instantiate (buildEffect,transform.position,Quaternion.identity);Destroy (effect,5);}}

明天实现炮台攻击！
