Hi, I mean like a ping pong paddle, where if you grab it, you can control it by moving it left or right,

Thanks, :) - Hunter

    Put a rule on the paddle that says:

    When touch is pressed constrain the paddles X and Y location to your touch location.

    "touch location" is in the expression editor, Devices » Mouse » Position » X and Y.

    @jamie_c THANKS! It worked :D, but how do I put a speed control on it?

    Move your finger at the speed you need the paddle to move at ?

    @jamie_c also, how do I make it so that if an actor goes completely to one side of the screen, he appears on the other side (like doodle jump)

    @Socks Yeah, but it looks kinda crazy if you move the mouse really fast.

    Since it's constrained to your touch position, it just follows your touch, as Socks says.

    If you want it to wrap around the screen maybe you need a different play mechanic? Since it's constrained to touch, you'd need to drag it back to the other side...

    Doodle Jump uses the accelerometer, not touch so it's a different play mechanic.

    @jamie_c Oh, okay then, thanks.

    But I also tried to set up walls, by creating a "Collide With Actor - Walls" but the paddle actor went right through the walls :(.

    Yes, that is because it's Constrained to your touch position, that overrides collisions. I think I've seen here in the forum a way to deal with that but honestly I'm not sure what it was. Maybe someone else remembers?

    I'm trying to follow this tutorial.

    mainly the part where he teaches you how to make the paddle have a limit of how far the paddle could go out of the screen, but the resolution is far too low, I can't read what he's typing into the expression editor :( can someone please help :-S

    Looks like it is:
    Constrain Attribute: self.Position.X To: min(max(game.Mouse Position.X,30),290)
