Dragging an object and let it go with the velocity before released

Ok so my question is simple and what I want to do kind of works in my project but so weird that the object sometimes goes in the wrong direction when I let it go.

So I have an actor what I can drag around on the x axis with an offset (I can grab the actor where I want without having to deal with the problem that it constrains to the Mouse Position when I touch it.) and now when I don't press it anymore I want that it keeps moving with the velocity before I released it in the direction I dragged it.

    Constrain Liner Velocity X to 30*( game.Mouse.Position.X - self.Position.X )

    With offset ("O"):

    Change O to mouse x - self x
    Constrain Liner Velocity x to 30 *(mouse x - self x) -30 * O

    (!@#$% you did understand me wrong. You thought that I want to keep it constraining to my mouse position after I released it? I want to let it move freely after that.)
    What I want to achieve :smile:
    Actor A:
    When touch is pressed it constrains to my mouse position (with the offset) on the x axis. Now I start dragging it with a speed 'z' and then I release the object, so touch isn't pressed anymore it's now released. Now I want that the object keeps moving with the 'z' speed on the x axis in the direction I dragged it.

    of course and it keeps constraining to the mouse position even if touch is released.
    So you didn't understand me wrong?

    Your rule (in the linked image) is nothing like what I suggested ! :) I have one change attribute and one constrain, your rule has one change attribute and three constrain attributes.

    Give my suggested code a quick try, it will take less than a minute to try and it really does work !

    Why not give my suggested code a quick try, it will take less than a minute to try and it does work !

    it s exactly what you suggested it was just added to my old code because I thought I still need that basic stuff and you're just adding the "releasing part"

    so in fact your code does works great when included in a touch is pressed rule. So where does that 30 come from?

    From the world of numbers :tongue:

    Higher values = tighter tracking
    Lower values = looser tracking

    When a Lady 15 and a Gentleman 15 like each other a lot they become really close and have what's called "addition" and that's where 30's come from.
