For anybody have the same problem, I�ve fixed it by using two sprites for my actor. One of them is with a platform behavior and the other one is with physic behavior. To use the especially properties of the behaviors I�ve worked with the spawn and destroy options in the condition editor.
For example:
Is the actor collide with a movable platform I�ve destroyed the physic behavior and spawn the platform behavior (in the other sprite). My actor was now carried by the movable platform.
Hope that help�s!
