is it possible to draw indexed triangles?

[NateS]

I'm writing the Spine runtime for SFML and I want to render a mesh. I have an array of vertices and UVs and I have an array of vertex indices that describe the triangles I want to draw (eg 0,1,2 ,1,2,3 ,2,3,4 would draw 3 triangles). Is it possible to draw this way using SFML? For now I'm just specifying the vertices multiple times, but this isn't ideal.

SFML doesn't support indexed drawing. Add the vertices to an sf::VertexArray using the index to select the right vertex from the vertex array.

sf::VertexArray vertexArray(sf::Triangles, count);

for (int i = 0; i < count; i++)
{
    vertexArray[i] = vertices[indices[i]];
}

Cool, that's what I'm doing, just wanted to check that I'm not missing something. Thanks!

Very cool. That's what I was searching and now I have solved my problem.
