## Unity的基本操作
**一、场景的基本操作**
- 缩放:鼠标滚轮
- 旋转:鼠标箭头左键点击后拖动
- 拖动场景位置移动:鼠标滚轮按下
### **二、人物模型的控制**
**2.1 人物的结构和手动控制**
如下图所示一般来说3D人物模型的身体部分都是躯体的骨骼模型按照多叉树的结构组织的。对于每一部分的躯体部分都可以控制其平移、缩放、旋转等操作。

完整的人物呈现如下图所示(默认状态):
<img src="./Image/Model_Default.png" style="zoom:50%;" />
对象的旋转、平移、缩放操作,可以通过窗口进行控制:
<div align=center><img src="./Image/Unity3D-Model-Transform.png" alt="image-20220916005017611" style="zoom:50%;" /></div>
设置手臂的Y轴旋转角度为-90°可以看到
<div align=center><img src="./Image/Model_UpperArm-90.png" style="zoom:50%;" /></div>
**2.2 人物脚本控制**
