unity2D笔记-制作死亡功能和游戏重开
对之前的viewpanel的单例基类做了优化，这样不用在子类进行单例的创建和判断了
并且可以根据不同 单例类名进行实例化 实例化的物体和类名要一致
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class SingletonView<T> : ViewBase where T:SingletonView<T>
{
// Start is called before the first frame update
public static T _instance;
public static T Instance
{
get
{
if(_instance == null)
{
Debug.Log(typeof(T).Name);
GameObject.Instantiate( Resources.Load<GameObject>("Prefabs/" + typeof(T).Name));
}
return _instance;
}
}
protected virtual void Awake()
{
_instance = this as T;
//因为继承该单例脚本的类名不一样 因此采用泛型 且泛型声明为需要继承SingletonView1.受伤脚本
在之前的脚本中加入了受伤状态来判断是受伤还是死亡，并在事件调用中增加了受伤状态参数和复位的位置信息。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Damage : MonoBehaviour
{
public int damage;//伤害
public HurtType hurtType; //受伤类型
public string ResetPos;//死亡复位
//对一个游戏物体造成伤害
public void onDamage(GameObject gameObject)
{
//是否能够受伤
DamageAble dam = gameObject.GetComponent<DamageAble>();
if (dam == null)
{
return;
}
dam.TakeDamage(this.damage, hurtType,ResetPos);
}
//对多个游戏物体造成伤害
public void onDamage(GameObject[] gameObject)
{
for(int i = 0; i < gameObject.Length; i++)
{
onDamage(gameObject[i]);
}
}
// Update is called once per frame
void Update()
{
}
}
2.施加伤害脚本
这里设置玩家的重生点，和保存了初始生命值以便于游戏结束重新恢复。
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public enum HurtType
{
Normal,
Dead
}
public class DamageAble : MonoBehaviour
{
public int health; //生命值
public int default_health; //最初的生命值
public Action<HurtType, string> OnHurt;
public Action OnDead;
public bool isEnable = true;
public void Start()
{
default_health = this.health;
}
public void Enable()
{
isEnable = true;
}
public void DisEnable()
{
isEnable = false;
}
public void TakeDamage(int damage,HurtType ht,string pos)
{
if(isEnable == false) { return; }
if (health < 0) return;
//血量减少
Debug.Log("SDA1" + health);
health--;
if (health == 0)
{
if(OnDead!=null)
OnDead();
}
else
{
if(OnHurt!=null)
OnHurt(ht,pos);
}
}
public void ResetHealth()
{
this.health = this.default_health;
Enable();
}
// Update is called once per frame
void Update()
{
}
}
3.玩家角色控制器脚本PlayController
类中的部分相关代码，依旧在之前的AWAKE函数中实现对受伤事件的注册
public void onHurt(HurtType ht,string pos)
{
this.currestpos = pos;
switch (ht)
{
case HurtType.Normal:
anim.SetTrigger("isHurt");//播放受伤动画
//设置无敌状态
SetWuDi(1);
break;
case HurtType.Dead:
SetDead();
//重置玩家位置
Invoke("ResetDead", 1f);
break;
}
GamePanel.Instance.UpdateHp(playerdam.health);
}
public void SetDead()//这里指的掉一条命的死亡
{
anim.SetBool("isDead", true);//播放死亡动画
anim.SetTrigger("triggerdead");
rgd2D.gravityScale = 0;
rgd2D.velocity =Vector2.zero;
PlayerInput.instance.SetEnable(false);
//显示黑屏
TipsPanel.Instance.showTips(null,TipsStyle.Style2);
}
private void SetWuDi(int time)
{
anim.SetBool("isWuDi", true);
playerdam.DisEnable();
Invoke("ResetDamageable", time);
}
public void ResetDead()
{
anim.SetBool("isDead", false);//播放死亡动画
PlayerInput.instance.SetEnable(true);
rgd2D.gravityScale = 5;
//复活有无敌
SetWuDi(1);
//设置位置
transform.position = GameObject.Find(this.currestpos).transform.position;
}
public void ResetDamageable()
{
anim.SetBool("isWuDi", false);
playerdam.Enable();
}
public void onDead()//血量全没有的死亡
{
Debug.Log("GAME OVER");
SetDead();
GamePanel.Instance.UpdateHp(playerdam.health);
//显示游戏结束界面
Invoke("DelayShowGameOverPanel", 1f);
}
private void DelayShowGameOverPanel()
{
TipsPanel.Instance.showTips(null, TipsStyle.Style3);
this.currestpos = "spawn1";
ResetDead();
GamePanel.Instance.ResetHp();
playerdam.ResetHealth();
}
4.提示面板
在提示面板中加入了死亡黑屏和 游戏结束界面
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public enum TipsStyle
{
Style1,//位于下方的提示
Style2,//死亡黑屏
Style3//游戏结束
}
public class TipsPanel : SingletonView<TipsPanel>
{
// Start is called before the first frame update
GameObject styleobj1;
GameObject styleobj2;
GameObject styleobj3;
protected override void Awake()
{
base.Awake();
styleobj1 = transform.Find("Style1").gameObject;
styleobj1.SetActive(false);
styleobj2 = transform.Find("Style2").gameObject;
styleobj2.SetActive(false);
styleobj3 = transform.Find("Style3").gameObject;
styleobj3.SetActive(false);
}
public void showTips(string content, TipsStyle style)
{
switch (style)
{
case TipsStyle.Style1:
styleobj1.SetActive(true);
styleobj1.transform.Find("Content").GetComponent<Text>().text = content;
break;
case TipsStyle.Style2:
styleobj2.SetActive(true);
//1.5s隐藏
Invoke("HideTips2", 1.5f);
break;
case TipsStyle.Style3:
styleobj3.SetActive(true);
//1.5s隐藏
Invoke("HideTips3", 1f);
break;
}
}
private void HideTips2()
{
HideTips(TipsStyle.Style2);
}
private void HideTips3()
{
Debug.Log("hide tip3");
HideTips(TipsStyle.Style3);
}
// Update is called once per frame
public void HideTips(TipsStyle style)
{
switch (style)
{
case TipsStyle.Style1:
styleobj1.SetActive(false);
break;
case TipsStyle.Style2:
styleobj2.SetActive(false);
break;
case TipsStyle.Style3:
styleobj3.SetActive(false);
break;
}
}
}
5.游戏信息面板
加了血量重置代码
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class GamePanel : SingletonView<GamePanel>
{
public GameObject hp_item_prefb;
Transform hp_parent;
GameObject[] hp_table;
protected override void Awake()
{
base.Awake();
hp_parent = transform.Find("Hp");
}
public void InitHp(int count)
{
hp_table = new GameObject[count];
for (int i = 0; i < count; i++)
{
hp_table[i] = GameObject.Instantiate(hp_item_prefb, hp_parent);//hp item
}
}
public void UpdateHp(int count) //更新
{
for (int i = count; i <hp_table.Length; i++)
{
if (hp_table[i].GetComponent<Toggle>().isOn)
{
hp_table[i].GetComponent<Toggle>().isOn = false;
}
//显示特效
}
}
public void ResetHp() //更新
{
for (int i = 0; i < hp_table.Length; i++)
{
hp_table[i].GetComponent<Toggle>().isOn = true;
}
}
}
