I can't get custom shapes to work
« on: May 27, 2019, 05:22:54 pm »
I found some examples of roundedrectangles/elipses, yet I can't get them to work. Build is fine with no errors, yet ".draw" shows nothing :/ It's been 3 days I'm trying to get it to work, and since I'm a total newbie, it feels like I can't pin point what I'm doing wrong.


here's the example I tryed, and for the elipses:


With the first example, I create an hpp, and a cpp, copy and paste, create a new shape in the int main, ask to draw it, and nothing appears. I'm lost :/

I even tryed replacing the end of the code by the code from the original rectangleshape, and it works .

// this does not work, draw shows me a shape
    if(index >= myCornerPointCount*4)
        return sf::Vector2f(0,0);

    float deltaAngle = 90.0f/(myCornerPointCount-1);
    sf::Vector2f center;
    unsigned int centerIndex = index/myCornerPointCount;
    static const float pi = 3.141592654f;

        case 0: center.x = mySize.x - myRadius; center.y = myRadius; break;
        case 1: center.x = myRadius; center.y = myRadius; break;
        case 2: center.x = myRadius; center.y = mySize.y - myRadius; break;
        case 3: center.x = mySize.x - myRadius; center.y = mySize.y - myRadius; break;

    return sf::Vector2f(myRadius*cos(deltaAngle*(index-centerIndex)*pi/180)+center.x,

// this does

    switch (index)
        case 0: return Vector2f(0, 0);
        case 1: return Vector2f(mySize.x, 0);
        case 2: return Vector2f(mySize.x, mySize.y);
        case 3: return Vector2f(0, mySize.y);

Do you still have a problem with this and if yes then can you create a minimal complete example of it?
