Float3类型，三个float属性XYZ，其中的两个运算符重载：
public static void operator +(ref Float3 ptr, Float3 obj1, Float3 obj2)
{
ptr = new Float3(new Float3
{
m_x = (float)((double)obj1.m_x + (double)obj2.m_x),
m_y = (float)((double)obj1.m_y + (double)obj2.m_y),
m_z = (float)((double)obj1.m_z + (double)obj2.m_z)
});
}
public static void operator -(ref Float3 ptr, Float3 obj1, Float3 obj2)
{
ptr = new Float3(new Float3
{
m_x = (float)((double)obj1.m_x - (double)obj2.m_x),
m_y = (float)((double)obj1.m_y - (double)obj2.m_y),
m_z = (float)((double)obj1.m_z - (double)obj2.m_z)
});
}
之前刚“见识”了无法显式调用属性的get set……还好在java里见过，所以自己写get set 函数解决了。这个就不知道怎么搞了
确实是想做个2D游戏来着。上班没事干的时候各种补知识，但时间还是少
