AI:原地巡逻自动攻击型
AI会在横版地图上向左向右移动,移动一段距离后会原地停止移动,等待一段时间后,会随机向左或向右移动,以此循环,其中AI移动速度,移动时间、停留时间均可以自行调控,当人物进入怪物攻击范围后 会自动面向人物进行攻击,攻击时不会移动,直至人物离开攻击范围,怪物受到攻击后会闪红,有血量:

AI属性面板:
AI动画设置,注意动画的命名要一样,不然需要修改代码:
需要注意的是,每个动画没有过度,直接切换,不然会有一些卡顿
人物标签需要设置为Player
怪物标签需要设置为Chameleon
如果想让怪物之间不能够相互碰撞,让怪物和玩家间可以相互碰撞,可以给怪物AI和玩家分别设置一个碰撞层级,方法如下:
首先我们需要为人物和怪物设置分别设置一个层级,一个是人物层级,一个是怪物层级,点击Layer下拉菜单:
添加一个层级:
接下来:
在编辑下拉菜单下找到Project Setting,将不想发生碰撞的两个层级较差的对勾取消掉
子弹攻击,AI掉血摧毁设置:
bullte为子弹,需要有boxCollider2D,勾选Is Trigger
