ошибка в glVertexAttribPointer

я хочу сделать вывод без vao, так как он сложнее для реализации, потому что данные спрайта находятся отдельно от его координат и параметров текстуры. вот как я текстуру создаю. это пока на первое время.

void Sprite::createFrame (const int count_x, const int count_y) {
    int maxCount = count_x * count_y;
    this->frame = new unsigned int[maxCount];

    gl::GenTextures (1, &this->frame[0]);
    printf ("genTextures: %d\n", gl::GetError());
    gl::BindTexture (gl::TEXTURE_2D, this->frame[0]);
    printf ("bindTexture: %d\n", gl::GetError());
    gl::TexParameteri (gl::TEXTURE_2D, gl::TEXTURE_MIN_FILTER, gl::NEAREST);
    printf ("texparameteri min: %d\n", gl::GetError());
    gl::TexParameteri (gl::TEXTURE_2D, gl::TEXTURE_MAG_FILTER, gl::NEAREST);
    printf ("texparameteri mag: %d\n", gl::GetError());
    gl::TexImage2D (gl::TEXTURE_2D, 0, gl::RGBA, GameObject::width, GameObject::height, 0, gl::RGBA, gl::UNSIGNED_BYTE, this->commonData);
    printf ("teximage2d: %d\n", gl::GetError());
    
    this->vertex[0] = 0;
    this->vertex[1] = 0;

    this->vertex[2] = 0;
    this->vertex[3] = GameObject::height;

    this->vertex[4] = GameObject::width;
    this->vertex[5] = 0;

    this->vertex[6] = GameObject::width;
    this->vertex[7] = 0;

    this->vertex[8] = GameObject::width;
    this->vertex[9] = GameObject::height;

    this->vertex[10] = 0;
    this->vertex[11] = GameObject::height;

    this->texture[0] = 0.0f;
    this->texture[1] = 0.0f;
    this->texture[2] = 0.0f;
    this->texture[3] = 1.0f;
    this->texture[4] = 1.0f;
    this->texture[5] = 0.0f;
    this->texture[6] = 1.0f;
    this->texture[7] = 0.0f;
    this->texture[8] = 1.0f;
    this->texture[9] = 1.0f;
    this->texture[10] = 0.0f;
    this->texture[11] = 1.0f;
}

потом рисую

void Sprite::draw () {
    printf ("------------\n");
    gl::UseProgram (shaderController->program[SHADERS::SPRITE]);
    printf ("useprogram: %d\n", gl::GetError());


    gl::ActiveTexture (gl::TEXTURE0);
    printf ("activetexture: %d\n", gl::GetError());


#if 1
    gl::BindTexture (gl::TEXTURE_2D, this->frame[0]);
    printf ("bind texture: %d\n", gl::GetError());
#endif

    gl::Uniform1i (this->location_tex, this->frame[0]);
    printf ("uniform1i: %d\n", gl::GetError());

    gl::UniformMatrix4fv (this->location_view, 1, gl::TRUE_, &GameObject::ortho[0][0]);
    printf ("uniformmatrix4fv: %d\n", gl::GetError());

    gl::Uniform3fv (this->location_pos, 1, &GameObject::pos[0]);
    printf ("uniform3fv: %d\n", gl::GetError());



    gl::EnableVertexAttribArray (0);
    printf ("enable vertex 0: %d\n", gl::GetError());

    gl::EnableVertexAttribArray (1);
    printf ("enable vertex 1: %d\n", gl::GetError());
  

    gl::VertexAttribPointer (0, 2, gl::FLOAT, gl::FALSE_, 0, &this->vertex[0]);
    printf ("vertex pointer 0: %d\n", gl::GetError());

    gl::VertexAttribPointer (1, 2, gl::FLOAT, gl::FALSE_, 0, &this->texture[0]);
    printf ("vertexpointer 1: %d\n", gl::GetError());


    gl::DrawArrays (gl::TRIANGLES, 0, 12);
    printf ("draw: %d\n", gl::GetError());

    exit (0);
    
}

вот вывод при рисовании.

что я не правильно делаю в vertex pointer?

последние исправления. вот что добавил в createFrame.

    gl::GenBuffers (1, &this->index_vertex);
    printf ("gen buffer vertex: %d\n", gl::GetError());

    gl::BindBuffer (gl::ARRAY_BUFFER, this->index_vertex);
    printf ("bind buffer vertex: %d\n", gl::GetError());

    gl::BufferData (gl::ARRAY_BUFFER, 12 * sizeof (float), 0, gl::STATIC_DRAW);
    printf ("buffer data vertex: %d\n", gl::GetError());

    gl::BufferSubData (gl::ARRAY_BUFFER, 0, 12 * sizeof (float), this->vertex);
    printf ("buffer subdata vertex: %d\n", gl::GetError());

    gl::GenBuffers (1, &this->index_texture);
    printf ("gen buffer texture: %d\n", gl::GetError());

    gl::BindBuffer (gl::ARRAY_BUFFER, this->index_texture);
    printf ("bind buffer texture: %d\n", gl::GetError());

    gl::BufferData (gl::ARRAY_BUFFER, 12 * sizeof (float), 0, gl::STATIC_DRAW);
    printf ("buffer data texture: %d\n", gl::GetError());

и поменял в draw

    gl::EnableVertexAttribArray (0);
    printf ("enable vertex 0: %d\n", gl::GetError());

    gl::EnableVertexAttribArray (1);
    printf ("enable vertex 1: %d\n", gl::GetError());
  
  
    gl::BindBuffer (gl::ARRAY_BUFFER, this->index_vertex);
    printf ("bindbuffer vertex: %d\n", gl::GetError());

    gl::VertexAttribPointer (0, 2, gl::FLOAT, gl::FALSE_, 0, reinterpret_cast< void * >(0));
    printf ("vertex pointer 0: %d\n", gl::GetError());

но не работает.

последний код в draw

void Sprite::draw () {
    printf ("------------\n");
    gl::UseProgram (shaderController->program[SHADERS::SPRITE]);
    printf ("useprogram: %d\n", gl::GetError());


    gl::ActiveTexture (gl::TEXTURE0);
    printf ("activetexture: %d\n", gl::GetError());


#if 1
    gl::BindTexture (gl::TEXTURE_2D, this->frame[0]);
    printf ("bind texture: %d\n", gl::GetError());
#endif

    gl::Uniform1i (this->location_tex, this->frame[0]);
    printf ("uniform1i: %d\n", gl::GetError());

    gl::UniformMatrix4fv (this->location_view, 1, gl::TRUE_, &GameObject::ortho[0][0]);
    printf ("uniformmatrix4fv: %d\n", gl::GetError());

    gl::Uniform3fv (this->location_pos, 1, &GameObject::pos[0]);
    printf ("uniform3fv: %d\n", gl::GetError());


  
    gl::BindBuffer (gl::ARRAY_BUFFER, this->index_vertex);
    printf ("bindbuffer vertex: %d\n", gl::GetError());    

    gl::VertexAttribPointer (0, 2, gl::FLOAT, gl::FALSE_, 0, reinterpret_cast< void * >(0));
    printf ("vertex pointer 0: %d\n", gl::GetError());

    gl::EnableVertexAttribArray (0);
    printf ("enable vertex 0: %d\n", gl::GetError()); 

    gl::BindBuffer (gl::ARRAY_BUFFER, this->index_texture);
    printf ("bindbuffer texture: %d\n", gl::GetError());

    gl::VertexAttribPointer (1, 2, gl::FLOAT, gl::FALSE_, 0, reinterpret_cast< void * >(0));
    printf ("vertexpointer 1: %d\n", gl::GetError());

    gl::EnableVertexAttribArray (1);
    printf ("enable vertex 1: %d\n", gl::GetError());

    gl::DrawArrays (gl::TRIANGLES, 0, 12);
    printf ("draw: %d\n", gl::GetError());

    exit (0);
    
}
