unity的transform

Unity的Transform是一个组件(Component),控制游戏对象的位置、旋转和缩放。它是所有游戏对象都具有的默认组件之一。
Transform组件有三个属性:position、rotation和scale。
1. position属性:控制游戏对象在场景中的位置。它是一个三维向量,代表游戏对象在x、y和z轴上的位置。
2. rotation属性:控制游戏对象的旋转。它是一个四元数(Quaternion),代表游戏对象在x、y和z轴上的旋转角度。
3. scale属性:控制游戏对象的缩放。它是一个三维向量,代表游戏对象在x、y和z轴上的缩放比例。
Transform组件还有一些方法,如Translate(移动游戏对象)、Rotate(旋转游戏对象)和Scale(缩放游戏对象)等,可以通过代码来调用。

unity transform
The Unity Transform component is responsible for storing and manipulating an object's position, rotation, and scale. It is a fundamental component that every game object in Unity has.
The Transform component has three main properties:
1. Position: This determines the object's location in the game world. The position is represented by a Vector3, which has three values (x, y, z) that define the object's position in 3D space.
2. Rotation: This determines the object's orientation in the game world. The rotation is represented by a Quaternion, which has four values (x, y, z, w) that define the object's rotation in 3D space.
3. Scale: This determines the object's size in the game world. The scale is represented by a Vector3, which has three values (x, y, z) that define the object's dimensions in 3D space.
The Transform component also has methods that allow for manipulation of these properties, such as Translate(), Rotate(), and Scale().
Overall, the Transform component is essential for positioning and moving objects in Unity and is one of the most commonly used components in game development.
unity Transform Rotate
Unity中的Transform.Rotate()方法用于旋转游戏对象的转换组件。该方法可以通过指定旋转角度以及旋转轴来实现旋转。具体用法如下:
```csharp
public void Rotate(Vector3 axis, float angle, Space relativeTo = Space.Self);
```
其中,axis是一个三维向量,表示旋转轴;angle表示旋转角度;relativeTo表示旋转相对于哪个坐标系进行,可以是自身坐标系(Space.Self)或世界坐标系(Space.World)。
例如,以下代码可以让物体绕着y轴旋转90度:
```csharp
transform.Rotate(Vector3.up, 90f, Space.Self);
```
需要注意的是,Transform.Rotate()方法并不改变游戏对象的旋转角度属性(rotation),而是在该属性基础上进行旋转。如果要直接设置旋转角度属性,可以使用Transform.eulerAngles属性。
