how do i draw lines/polygons?
« on: December 10, 2012, 11:47:48 pm »
Hey folks :)

How do i draw all kinds of primitives?
I know circleshape and rectangleshape, that was pretty easy,
but cant seem to figure out how to draw lines and polygons

ive looked at the documentation but i cant figure it out, 
and also the 1.6 tutorials... but it doesnt work the same as 2.0 :(

I will be grateful for any help you guys can provide  :D

sf::ConvexShape for convex shapes
sf::Vertex or sf::VertexArray for 1 pixel wide lines
For concave shapes and wide lines you'll have to write or find some other code.

thor::ConcaveShape
I just knew you'd come and say that. ;D
Rectangles let you draw only vertical or horizontal lines though, unless you do the math and rotate it properly but then it's easier to write own, proper line class. :P
There is round ended line class floating on wiki or forum somewhere too I think.

If you want to go further by knowing how thor's concave shapes work or eventually implement a bold line or something  similar yourself you can check this topic:

I gave a small explanation of how to do it, requires a lot of math and all, but it's good to have that knowledge around.

So why didn't you write it directly? :P
