【unity小技巧之三】添加自定义拓展，动态向某个类注入静态函数

有的时候想直接通过transform.position.x=10f;的时候，编译器会报错，必须这样写

transform.position = new Vector3(10f, transform.position.y, transform.position.z);

这样特别的不方便，然而C#3.0新加入一个特性，就是通过this关键字动态的向某个类注入静态函数，比如：

using UnityEngine;
using System.Collections;

public static class ExtraTransform {

public static void SetX(this Transform transform, float x)
{
Vector3 newPosition =
new Vector3(x, transform.position.y, transform.position.z);
transform.position = newPosition;
}

public static void SetY(this Transform transform, float y)
{
Vector3 newPosition =
new Vector3 (transform.position.x, y, transform.position.z);
transform.position = newPosition;
}

public static void SetZ(this Transform transform, float z)
{
Vector3 newPosition =
new Vector3 (transform.position.x, transform.position.y, z);
transform.position = newPosition;
}

public static float GetX(this Transform transform)
{
return transform.position.x;
}

public static float GetY(this Transform transform)
{
return transform.position.y;
}

public static float GetZ(this Transform transform)
{
return transform.position.z;
}
}

所以上面的代码直接写transform.SetX(10f);即可，这样代码写起来更加快捷~~~



提示：静态类不能拓展MonoBehaviour类。
