  use 'constrain attributes' while touch is pressed.... I'm assuming 'change attribute' is used at the moment. . . if not hopefully someone who is familiar with the tutorial will help.

  Indeed 'change attribute' is used.I changed it to 'constrain attribute' but it doesn't work.The line does not appear in the screen anymore.

  Learning to draw a line in GameSalad is not a trivial thing. But it is a great way to learn many of the fundamentals. When developers can do a simple line (and understand why it is done the way it is), they are well on their way to mastering some of the most powerful concepts in GameSalad. (Actor Positioning, Creating Attributes, Changing vs. Constraining Attributes, Magnitude, VectorToAngle)
  
  Here goes!
  
  Change Attribute: self.Size.Height To: 2
  When mousebutton is down
  -- Change Attribute: beginX To: game.Mouse.Position.X
  -- Change Attribute: beginY To: game.Mouse.Position.Y
  -- Constrain Attribute: self.Position.X To: ( game.Mouse.Position.X + self.beginX )/2
  -- Constrain Attribute: self.Position.Y To: ( game.Mouse.Position.Y+ self.beginY )/2
  -- Constrain Attribute: self.Size.Width To: magnitude( game.Mouse.Position.X - self.beginX , game.Mouse.Position.Y - self.beginY )
  -- Constrain Attribute: self.Rotation To: vectorToAngle( game.Mouse.Position.X - self.beginX , game.Mouse.Position.Y - self.beginY )
