Platformer

I am creating a game using Box2D (Javascript implementation) - and I added the ability to have a static platform, that is moved along an axis as a function of a sine.

My problem is when the player lands on the platform, as the platform moves along the X axis - the player is not moved along with it, as you visually would expect.

The player can land on the object, and if it hits the side of the object, it does colide with it and is pushed.

This image might explain better than I did:
After jumping on to the red platform the player character will fall off as the platform moves to the right

example

UPDATE:
Here is a live demo showing the problem:

Are high powered 3D game engines better at 2D games than engines made for 2D

I'm a software engineer that's new to game programming so forgive me if this is a dumb question as I don't know that much about game engines. If I was building a 2D game am I better off going with an engine like Torque that looks like it's built for 2D, or would higher powered engines like Unreal… >>> More

I want to create a 2D array that contains many other 2D arrays.

I've been trying out some rope-physics recently, and I've found that the "standard" solution - making a rope from a series of objects strung together with springs or joints - is unsatisfying.
