Drawing lines in sfml.
« on: April 10, 2012, 02:44:49 pm »
Hello,

Can someone please explain me how to draw lines? I guess it can be done by creating a 1 px high rectangleshape and rotating it but is there a clena solution for this? I *thought* the was a Line class in SFML but I can't seem to find it.

You know there's a search function for this forum (and every other forum you'll ever visit). ;)

Since you're talking about rectangleshape I suppose you're using SFML 2, which is already a good thing.
A line can be done simply with to vertices (sf::Vertex) and a vertex array (sf::VertexArray).
As primitve type you can choose sf::Lines.

The line class was removed; since it didn't do anything that a rotated rectangle couldn't do anyway.

Just incase someone doesn't realize thePyro_13 is joking, the old (SFML 1.6) removed function was called:
sf::Shape::Line and drew a single line slowly.

The new method (SFML 2.x), using sf::VertexArray, as eXpl0it3r mentioned, draws many lines at once (a much faster way to draw, if you're drawing more than one line).

Nice nekroing there... ;D

And no thePyro_13 was not joking. There is not line class in SFML 2.x anymore. The use of vertex array does not equal as a class, so the answer is correct. ;)
