I use to use windows and c# for my applications but my move to a mac(still in high school , its not a job i am talking about) I am using c/obj-c. I know opengl is one thing apple totes(sp) but I am looking for a tutorial based on the os x system(xcode preferred). I know you can write in pure c and that helps it become cross platform but I am interested in apples method of implementing it with obj-c. I know tutorials at videotutorialsrock.com,nehe,and others but it seems that there is a lack of apple centric ones(if that makes sense). I use to use MDX to make some basic 2d games and I was planning to try to do that with opengl because its the other option as well as looked easier and is still around. Is it just better to use c style tutorials or should I keep looking for obj-c /apple made ones on the basics. I know the basics of objective c. thanks for the help in advanced.
