Hi, Monks!

I want to know how to correctly move/scroll 2D background images in Perl SDL. I have done that and it went fine, yes it's scrolling but i think this is not the proper way ... so if there's anyone that knows how to correctly 'SCROLL' a 2D background image in Perl SDL, please guide me. Thanks.

Here's the link of my code: http://pastebin.com/TAyCgF8A

Hi, Looks "fine" to me , thats pretty much how sdl works, however, I would compare/contrast to https://metacpan.org/requires/module/SDL?sort=%b5%b52,1%d5%d5 As you should use argument passing instead of fake globals ... like so many tk apps :)	[reply]
