Moving an actor

Evolithic

Using the windows version, its hard for a first timer like me to watch mac tutorials and follow along. I have read around on the forums, but I cant get my actor moving.

I am either doing something wrong, or I'm missing a vital piece of information.

So I have 2 questions,

1. How can I make an actor follow a touch movement? Imagine a long level, where I control the actor by sliding my finger.

2. This one is probably easier, but I want my actor to collide with the roof and floor, and not leave the screen.

I am mostly interested in answers to question 1, so I can actually start making a game.

Thanks!

1. Group Touch = pressed
do
constrain
device touch 1 x = self position x
2. main actor collide with actor roof and floor, uncheck roof and floor invisible and movable set physic of main actor ,roof and floor friction = 3 .
