1.委托有匿名委托，不是必须带有委托名
委托可以把一个方法作为参数代入另一个方法;
事件可以看做是一种特殊的委托
委托可以理解为指向一个函数的引用(指针)
2.IK动画不是只有人型动画才能设置，只要有avarar都可以设置IK动画
3.RectTransform是Transform 的子物体，有Transform 的全部特征，Unity UI系统使用Rectform实现基本的布局和层次控制，在Inspector界面上,为了更方便的调节RectTransform的属性,锚点的两个点重合时会显示位置和宽高.RectTransform组件负责组织GameObject的层级关系.
4.使用IK动画要实现系统自带函数OnAnimatorIK（int LayerIndex）
5.Blend Tree：1D一个方向整合
2D Freeform Directional，同一方向上可以有多个动画，不建议有动作相似的动画。
2D Freedform Cartesian，可以在X轴和Y轴使用不同的定义，自有定义动作
Direct融合表情
6.动画遮罩和IK：可以给全身添加IK，不是只有人形动画才能设置IK，只要有avator都能设置IK
7.声音视频资源不能作为预设体，图片转为精灵之后可以作为预设体
8.四元数相对于欧拉角的有点：1)能进行增量旋转(插值，缓动旋转)
2)避免万向节锁
3)给定方位的表达方式有两种，互为负(欧拉角有无数种表达方式)
任意选择⼀一个场景(如果电脑性能不不佳, 直接使⽤用Plane及Cube等搭建⼀一个简单场景),选择⼀一个⻆角⾊色,⼩小地图(可显示场景,玩家,及可拾拾取和不不可拾拾取物品),随机产⽣生可拾拾取物品和不不可拾拾取物品,玩家通过⿏鼠标点击控制⻆角⾊色移动(使⽤用导航);(20)可拾拾取物品:拾拾取后玩家能看到实时的显示(显示⽅方式⾃自定)(10);不不可拾拾取物品,拾拾取后减少玩家剩余游戏时间(游戏以时间为计时,减少数值⾃自定义);(10)游戏结束显示结束界⾯面,显示玩家最终得分(以拾拾取到的物体数为基准,⾃自定义等分规则)(5)玩家游戏时间结束,播放玩家死亡动画,(5)
