L-System drawer

[MenosGrandes]

Hallo I have problem with drawing a L-System.
I have created a class that implementing base L-System, but I don't know how to draw it.
I have tried using sf::VertexArray with sf::LineStrip and sf::RectangleShape. In VertexArray I don't know how to rotate next line.

Any sugesstions?

How far did you actually "try"? I mean if you use vertices you obviously have to calculate the proper rotation yourself (maybe with use of an sf::Transform?). And what was the issue with rectangle shapes?

Since we don't know your system, all we can tell you is to draw something somehow. Maybe if you provide more information someone might be able to help further. Also don't assume that everybody just knows what an L-System is.

I have something like this:

float currentRotation=0;
float rotate=90;

sf::Vector2f currentPosition(0,0);

        m_vertices.setPrimitiveType(sf::LinesStrip);
        m_vertices.resize(initializer.length());
       // sf::Vertex* quad2 = &m_vertices[0];
        //m_vertices[0].position = currentPosition;

for(int i=0;i<initializer.length();i++)
{


    char sign=initializer[i];
    switch(sign)
    {
        case '+' :
            //std::cout<<" + ";
/* Rotate left*/
currentRotation+=rotate;

            break;
        case '-' :
            /* Rotate right*/
           // std::cout<<" - ";
currentRotation-=rotate;
            break;
        case 'F' :
           // std::cout<<" F ";
currentPosition.x+=1;
currentPosition.y+=1;
m_vertices[i].position = sf::Vector2f((currentPosition.x), (currentPosition.y));
//std::cout<<quad[i].position.x<<" "<<quad[i].position.y<<"\n";
            break;

    }

}
 

and I dont know how to calulate the rotation..

*cough* This may help you.

I'm so dumb... thank you;)
