Set the friction of tiles.

How can I set the friction of certain tiles ?
Like making the player run very fast on frictionless tiles;
run epic slow in rough friction tiles ?

You can't.  Try using regions instead.

I can't ? Recently I saw a post similar to this but I can't find it no more...
And btw could you explain the regions to me instead ?
It'll be a big help for me

This might be of help to you, it's a topic on this exact thing I believe http://community.stencyl.com/index.php/topic,5499.msg35556.html#msg35556

Also check out my reply in this thread for another way to do it using actors
