Graphics / SFML does not wan't to draw a line

Yeah, I know the code is quite messy (it was written fast just to test some code, but you're wriht: this shouldn't be an excuse)

Yes vec2D is a mathematical 2dimensional vector, but I wanted it to have more functionalities(the startpoint) because for some calculations is is handy that you've got a startpoint.

The zerovectors were there to experiment with other functionalities, but this isn't that important too.

Yes I used using namespace sf, but some code I copy pasted from a former program, where I didn't use it. But that shouldn't be a problem i guess?

When I increase line thickness, nothing changes. But I just think it's weird, because it prints out the values i want it to print. And these values are being sent but nor printed in the screen.

The couts i put there were simply to test if the right values were given

Graphics / SFML does not wan't to draw a line

Hi,

I am trying to making my own game in my spare time. (It's a project I'm doing on my new website webthomas.sharkserve.com, which is actually part of the project too).

Now I've written a class called vec2D. I think it was all okay, but 1 problem kept occuring:
There's one line it doesn't want do draw.

Code: [Select]

void printvec(vector<vec2D> v, int n){
RenderWindow win(VideoMode(1000, 1000), "screen");
win.Clear(sf::Color::Black);
for(int i1=0; i1<=n;i1++){
win.Draw(Shape::Line(v[i1].getStartX(),v[i1].getStartY(),v[i1].getStartX()+v[i1].getVecX(),v[i1].getStartY()+v[i1].getVecY(),2,Color::Green));
cout <<v[i1].getStartX()<<' '<<v[i1].getStartY()<<' '<<v[i1].getStartX()+v[i1].getVecX()<<' '<<v[i1].getStartY()+v[i1].getVecY()<<endl;
}
win.Display();
while (win.IsOpened()){
Event Event;
while (win.GetEvent(Event)){
//Sluit het scherm
if (Event.Type == Event::Closed){//het scherm sluiten
win.Close();
}
}
win.Clear(sf::Color::Black);
for(int i1=0; i1<=n;i1++){
win.Draw(Shape::Line(v[i1].getStartX(),v[i1].getStartY(),v[i1].getVecX(),v[i1].getVecY(),1,Color::Green));
}
win.Display();
}
return;
}

the output of this function is:
0 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0
20 20 120 60
20 20 60 120
140 140 280 280
0 0 0 0

which is allright, except that id doesn't want to draw the line starting at (140,140) going to (280,280)
