A fast, easy to use, free, and community supported 2D game engine
Hi everyone. Really enjoying Cocos. Thanks very much to Riq, and anybody else who's been working on it.
I have a question: I added a draw function to a layer to use the drawline function, and it worked perfectly on the simulator, but on an iPhone, it comes up as 1 pixel wide no matter what I set the line width to. Is this a problem with my hardware, or am I doing something stupid?
Cheers,
Andrew.
Hi,
I know I've read somewhere that the line width does not work in the iphone, just not sure where I read it (maybe the old forum) or why it did not work.
I did find this (http://lists.apple.com/archives/mac-opengl/2008/Jun/msg00074.html) that shows that you're not the first to find this :) maybe someone else can tell you why it happens.
For a workaround, I found this:

basically he goes by building a line from triangles to be able to get them textured. Hope it helps.
But if you just use the drawLine method of the Primitives class it works just fine.
sample code:
//accelerator view
glColor4f(0,0,0,0.3);
drawLine(cpv(0, 50),cpv(105,50));
glLineWidth(30);
glColor4f(0.5,0,0,0.6);
drawLine(cpv( 0, 50),cpv( sliderValue*70+30, 50 ));
glLineWidth(1);
glColor4f(1,1,1,1);
