This is probably trivial but I just can't make a break thru.

I've got C++ code using glm like so:

   struct Vertex
    {
        glm::vec3 position;
        glm::vec3 color;
    }

    Vertex triangle[] =
    [
        glm::vec3(0.0,  1.0, 0.0),
        glm::vec3(1.0,  0.0, 0.0),   // red

        // code removed for brevity.
    ];


And in D I'm using the gl3n library instead of glm.


    struct Vertex
    {
        vec3 position;
        vec3 color;
    }

    Vertex triangle[6] =
    [
        vec3(0.0,  1.0, 0.0),
        vec3(1.0,  0.0, 0.0),   // red

       // code removed for brevity.
    ];

I keep getting the following:

MeGlWindow.d(171): Error: cannot implicitly convert expression (Vector([0.000000F, 1.00000F, 0.000000F])) of type Vector!(float, 3) to Vertex
MeGlWindow.d(172): Error: cannot implicitly convert expression (Vector([1.00000F, 0.000000F, 0.000000F])) of type Vector!(float, 3) to Vertex
MeGlWindow.d(174): Error: cannot implicitly convert expression (Vector([-1F, -1F, 0.000000F])) of type Vector!(float, 3) to Vertex

You have to be explicit:

    Vertex[6] triangle = /* [1] */
    [
        Vertex(
            vec3(0.0,  1.0, 0.0),
            vec3(1.0,  0.0, 0.0),   // red
        ),
        ...
    ];

[1] `Vertex triangle[6]` works, but please don't do that.

Thanks. I assume you would prefer I use triangle[] but with OpenGL calls the dynamic arrays don't work.  But maybe that is another question for another time.

No no, Vertex[6] as a type is fine. It's about where you put that "[6]":
Vertex[6] triangle; /* D style - yay */
Vertex triangle[6]; /* C style - boo */

Oh, sure. Code has been changed.  Bad habits are hard to kill.

Oh sure, I've changed the code. I wish D had been my first language.
