初始化结构向量与括号包含初始化列表 [英] Initializing struct vector with brace-enclosed initializer list

问题描述

我这样初始化正常类型的向量：

I initialize normal-type vectors like this:

vector<float> data = {0.0f, 0.0f};

但是当我使用结构而不是普通类型时

But when I use structure instead of normal-type

struct Vertex
{
    float position[3];
    float color[4];
};
vector<Vertex> data = {{0.0f, 0.0f, 0.0f}, {0.0f, 0.0f, 0.0f, 0.0f}};

我收到错误无法转换'{{0.0f，0.0f， 中的<0.0f，0.0f，0.0f，0.0f，0.0f，0.0f}}。这有什么问题？

I get error could not convert '{{0.0f, 0.0f, 0.0f}, {0.0f, 0.0f, 0.0f, 0.0f}}' from '<brace-enclosed initializer list>' to 'std::vector<Vertex>'. What's wrong with this?

推荐答案

缺少一组 {} ：

std::vector<Vertex> data =
{ // for the vector
    { // for a Vertex
        {0.0f, 0.0f, 0.0f},      // for array 'position'
        {0.0f, 0.0f, 0.0f, 0.0f} // for array 'color'
    },
    {
        {0.0f, 0.0f, 0.0f},
        {0.0f, 0.0f, 0.0f, 0.0f}
    }
};
