Twitch Training Stream - Creating a 2D Side-Scroller p.3 - Jan 26th, Live from Epic HQ

hi just started to watch your series of videos and also started to use UE4 to make an old school 2d plateforme game.
the first few things like moving from left to right, jumping and throwing things i kind of get it. my first question would be : if i want to add other movements like crouching down, look up, crouch down and attack with a sword how do i do it ???
thanks in advance
