I''ve been playing around with SDL for a few weeks now, and have recently completed a primative blackjack game (thanks to some help from some of the people here). Anyways I would like to move on and make a 2D platformer in the style of the old Mega Man games, or maybe even Metroid. Anyways, I tried to do it on my own, and all I could figure out was how to get him to jump up and down, and move left and right. So I need some help. Could anyone refer me to an online tutorial for platformers, or maybe a book? Also, should I stick with learning SDL for now, or should I move on to OpenGL or DirectX? Thanks in advance.

There''s a big gap between BlackJack and MegaMan.
Try some static world first, something like PacMan.

Hmmm... maybe I should do that.
