Platformer Character Control

Jan 27, 2012 at 11:06 PM

Hi, recently I read this article: http://amazingretardo.simiansoftwerks.com/2010/02/17/platformer-character-control-farseer-physics-engine/

and I've been thinking about implementing it. But I have some doubts. When you're in the border of a platform, i guess you'll go down because of the circle. Also, when he suggest ray casting for the jumping function, is it really better than just contact detection?

Because I currently use contact detection so I can change the impulse the players takes depending on the surface (i.e. player jusmps less in water floor, and more in elastic floor).
