thanks!

    I think you would want to use the actors self.position x & y. You can offset the x or y by adding +/-100 or whatever value you want to it.

    If you Google rotate offset gamesalad you'll find plenty of posts about that.

    This will simply move the actor to a different position (where it will still rotate around it's centre).

    This is not an automatic thing in GameSalad. There is no way to just designate where the pivot point should be (yet). I am sure the good folks at GameSalad will get to it eventually. Meanwhile, there is a way to do it yourself. But it requires some basic trigonometry. A demo can be found here:

    How can I find out the coordinated ( point blank) of gameSalad in this image:

    Constrain X to 36.5*sin( game.Time *150)+AAA
    Constrain Y to 36.5*cos( game.Time *150)+BBB
    Rotate / clockwise /speed 150

    AAA = wherever you want the centre of the clock arm to be in the X axis.
    BBB = wherever you want the centre of the clock arm to be in the Y axis.

    I try to use the answer of "RThurman", but i can't to find the coordinates of the point blank;

    "Socks" I have to use only your answer or use with answer of the "RThurman"?

    Never use my answers with the answer of the RThurman, it could cause an explosion, use each answer by itself.

    Another trick to make things simple is to make the background to your 'clock hand' (I guess it's a clock hand) twice as long - with the clock hand down at one end - like this you can use a simple rotate behaviour.

    I hope that makes sense !

    In reality this is a game! and is not a "wristwatch", is a rectangle and should revolve around the white point of the image!
    I try to use only your answer, I can only the night. After test I post to result
    and yes it seems with "clock hand"!! kkkkkk

    I see a quick demo, but I want to rotate on the white point, as if a nail there...

    Well your English is better than my Portuguese ! :)

    But I don't really understand your question : (

    @Socks is so, I need rotate my entire image on this white point. You know when an image is added to an actor he wears the center as a reference when execute to rotate, I want to rotate all in the white point

    I made you a demo above.

    I know but not happened, what I expected... !!

    ?

    In the demo the image rotates around the white point ?
  • brunoocasali@gmail.combrunoocasali@gmail.com Member Posts: 20
    she didn't not rotate in the image end,
  • SocksSocks London, UK.Member Posts: 12,822
    "Image end" = "white point" ?
  • brunoocasali@gmail.combrunoocasali@gmail.com Member Posts: 20
    No, it rotates in the extreme right image

    Too late! He crossed the streams!

    Bruno, this is what @Socks gave you:
    --Constrain Attribute: self.Position.X To: 35.5*sin(game.Time*150)+200
    --Constrain Attribute: self.Posiiton.Y To: 35.5*cos(game.Time*150)+150

    Bruno this is what you did:
    --Constrain Attribute: self.Position.X To: 35.5*sin(self.offSetX*150)+200
    --Constrain Attribute: self.Posiiton.Y To: 35.5*cos(self.offSetY*150)+150

    Do you see the difference?
  • brunoocasali@gmail.combrunoocasali@gmail.com Member Posts: 20
    but two solved nothing for me:
    the two examples
    https://www.box.com/s/jtacslsfbmj14bhkz74m

    notRotate2 : game.Time
    notRotatee : offSet's

    i want to rotate around the white point!! :)

    The example using game.Time works just fine. But you need to fix some of the numbers.

    The first number needs to be the distance between the center of the actor and the point you want to rotate. The actor in your example is about 110 pixels tall. So the number would need to be around 55.

    Next, the rotation speed will always need to be the same as the "speed" multiplier. (If it is game.Time*150, then you need to set the rotation speed to 150.)

    So the behaviors are:
    Constrain Attribute: self.Position.X To: 55*sin(game.Time*150)+200
    Constrain Attribute: self.Posiiton.Y To: 55*cos(game.Time*150)+150
    Rotate (clockwise) Speed:150

    Dude, I guess you don't understand my question...
    I want to rotate about the white point
    It would be as if he had a nail in place of the white point

    So it seems that it creates a circle around him and rotate
