gamemaker - platforms + ramps

hey, does anyone here use gamemaker?
i've been playing with it, and i've made a platform engine with enemies that regenerate off-screen, wall-jumping, hooks you can grab, dashing, conveyors... but what I really want are moving platforms that push you around and crush you like cave story or magna centipede's level in X2. everything i've tried has failed. I might ask the gamemaker forums but they're full of stupid. any suggestions?
