Platform whitespace Problem.

I have made a small example to see what is my problem:

I'm use sin(..) to place the platform (yes i need that, not the inbuild-sin behavior).

The problem is, when the player goes down, i have a small whitespace between the player and the platform:

Any idea how can i fix this?

The "terminal velocity" of the platform object is less than the sin object.

Maybe set it to match while its overlapping it, or disable the behavior, and do your own movement.

There's many other ways.
