Recently I have updated to cocos2d 2.0.0 and the OpenGL line drawing doesn't work anymore. I guess it is because the OpenGL ES 1.1 is not compatible with the 2.0 API.
Could somebody help me or point me how to draw a line using OpenGL with OpenGL ES 2.0 ?

I cannot get the posted "drawSmoothLine" function to work with Cocos2D 1.0.1

I just see a blank, black screen when I call the method, no lines are drawn.

I cannot get any OPENGL primitive draw commands to work unless they are within a

-(void) draw {

}

method within an Objective-C class that I have created. Where is the "drawSmoothLine" function suppose to be placed, in what class and where, so that it may be used? Is Cocos2D constantly scanning all classes looking for a "draw" method to execute in them?

Either put the code from drawSmoothLine into the draw-method, or call said method from the draw method.

Look at the drawPrimitivesTest.m in the cocos source for an example of using primitive draw functions.

@pimms Thanks, with your suggestion, I got it working.

@araker I've been looking at the drawPrimitivesTest and the class it calls methods from as well.
