Controlling Sine Behaviour a bit better

I want to create a vertically moving platform, and I'm using the Sine behaviour on it. When I place the object in the layout, is the expectation that it is the middle point of the sine? I'm trying to determine where to best place it so that it lines up at the top of the wave and the bottom of the wave with appropriate postions.

Never mind I figured it out. The unfortunate aspect is the platforms have to be equidistant apart, and place the sine object exactly in the middle of the two platforms...

Perhaps the moveto behavior could give you more controllable results.

You could also try the Litetween or Easetween behaviors.

Would Moveto also move a character or enemy object if they were on the platform? If so, perhaps that would be better...

If the platform had the solid behavior it will move the character.
