如标题所示最近感觉有些没活了或者说是趁热打铁再制作更多的敌人于是本期的主角就决定是两个大家刚进入空洞骑士就经常看到的敌人另一个爬虫Crawler和飞虫Fly。 一、制作敌人另一个爬虫Crawler
1.公式化导入制作另个爬虫Crawler素材
首先我们先完成Crawler的完整行为第一步导入素材分别为它制作tk2dspritecollection和tk2dspriteanimation 然后就到了公式化设置一个敌人的时候了Rb2d , audiosource, boxcollider2d 可以看到它不需要其它的子物体因为只需要执行行走死亡转向的状态。
2.制作另一个爬虫Crawler的Crawler.cs状态机
创建同名函数给该游戏对象
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Crawler : MonoBehaviour
{public float speed;[Space]private Transform wallCheck; //墙面检测的位置private Transform groundCheck; //地面检测的位置private Vector2 velocity; //记录速度private CrawlerType type;private Rigidbody2D body;private tk2dSpriteAnimator anim;private void Awake(){body GetComponentRigidbody2D();anim GetComponenttk2dSpriteAnimator();}private void Start(){float z transform.eulerAngles.z;//通过transform.eulerAngles.z来判断哪种类型的Crawlerif (z 45f z 135f){type CrawlerType.Wall;velocity new Vector2(0f, Mathf.Sign(-transform.localScale.x) * speed);}else if (z 135f z 225f){type ((transform.localScale.y 0f) ? CrawlerType.Roof : CrawlerType.Floor);velocity new Vector2(Mathf.Sign(transform.localScale.x) * speed, 0f);}else if (z 225f z 315f){type CrawlerType.Wall;velocity new Vector2(0f, Mathf.Sign(transform.localScale.x) * speed);}else{type ((transform.localScale.y 0f) ? CrawlerType.Floor : CrawlerType.Roof);velocity new Vector2(Mathf.Sign(-transform.localScale.x) * speed, 0f);}//TODO:CrawlerType crawlerType type;if(crawlerType ! CrawlerType.Floor){if(crawlerType - CrawlerType.Roof 1){body.gravityScale 0;//如果在墙面面上rb2d的重力就设置为1}}else{body.gravityScale 1; //如果在地面上rb2d的重力就设置为1//TODO:}StartCoroutine(Walk());}/// summary/// 使用协程实现Walk函数循环直至hittrue后挂起然后启用协程Turn()/// /summary/// returns/returnsprivate IEnumerator Walk(){for(; ; ){anim.Play(Walk);body.velocity velocity;bool hit false;while (!hit){if(CheckRayLocal(wallCheck.localPosition,transform.localScale.x 0f ?

Vector2.down : Vector2.up, 1f)){hit true;break;}yield return null;}yield return StartCoroutine(Turn());yield return null;}}/// summary/// 使用协程实现转向函数/// /summary/// returns/returnsprivate IEnumerator Turn(){body.velocity Vector2.zero;yield return StartCoroutine(anim.PlayAnimWait(Turn));transform.SetScaleX(transform.localScale.x * -1f);velocity.x velocity.x * -1f;velocity.y velocity.y * -1f;}/// summary/// 发射射线检测是否有LayerMask.GetMask(Terrain).collider/// /summary/// param nameoriginLocal/param/// param namedirectionLocal/param/// param namelength/param/// returns/returnspublic bool CheckRayLocal(Vector3 originLocal, Vector2 directionLocal, float length){Vector2 vector transform.TransformPoint(originLocal);Vector2 vector2 transform.TransformDirection(directionLocal);RaycastHit2D raycastHit2D Physics2D.Raycast(vector, vector2, length, LayerMask.GetMask(Terrain));Debug.DrawLine(vector, vector vector2 * length);return raycastHit2D.collider ! null;}private enum CrawlerType{Floor,Roof,Wall}
}回到Unity编辑器中如果你的是开始往左走的话记得设置speed为负数 只需要这个就行了。我们不需要挂载Lineofsightdetector.cs这个就是敌人发现敌人到自己攻击范围的脚本
3.制作敌人另个爬虫Crawler的playmaker状态机
创建一个名字叫Crawler的playmaker状态机 变量和事件如下所示 同样我们还需要自定义脚本
using System.Collections;

1.公式化导入制作飞虫Fly素材
这里就不过多赘述了直接上图 这里需要注意到Fly有两个子游戏对象用于检测是否碰到其它敌人需要转向只不过这些都是后面设计要用的所以先不管 还有就是我们要开始导入PlayMaker Unity 2D用于检测场景中涉及到playmaker 2d的物理碰撞
这里是我已经导入了所以是灰色的你导入后会发现多生成了一个预制体 再给我们fly添加一个脚本叫PlayMakerUnity2DProxy.cs: 2.制作敌人飞虫Fly的playmaker状态机
完成上述过程中就到了创建playmaker状态机环节在这里我只用一个playmaker状态机完成Fly完整的循环 变量和事件如下所示 此时还需要继续自定义脚本这就要用到上面提到的 playmaker 2d的物理碰撞了

首先我们来看看Crawler的转向效果能不能实现 我们再来看看Fly的状态机能不能正常运行
我们可以创建一个闭环的四边形并给他一个TerrainLayer 完美运行下一期我们来丰富一下玩家的行为吧。
