LineStrip Attempt
« on: August 30, 2016, 01:36:46 am »
Hello everyone

I am trying to encorporate SFML LineStrip into my existing/working program and I am having some small difficulties. For one, I'm not sure how to use something that is within the PrimitiveTypes.hpp

But for some reason, when I try to use sf::VectorArray it complies but causes a runtime error. The typical dll error: pFirstBlock == pHead error

I feel like I linked it up properly (considering that in the existing program I use Circles, Rectangles, Text, various colors, etc.)  but there could potentially be a small problem there. Otherwise I'm not sure why its working.

This is the code I'm trying to implement and if I comment everything, it works perfectly. If I comment everything except the first line, there is an error.

sf::VertexArray lines(sf::LinesStrip, 4);
lines[0].position = sf::Vector2f(10, 0);
lines[1].position = sf::Vector2f(20, 0);
lines[2].position = sf::Vector2f(30, 5);
lines[3].position = sf::Vector2f(40, 2);


at a later point I do gui.draw(lines, sf::RenderStates()); // in which gui is my window
again, it builds perfectly normally. There is an error at runtime. Thanks in advance.

Your code is ok, you have probably messed up your SFML installation.
//edit: Btw tested on your version – 2.3.2(+dfsg-1).
