just a wild guess, but maybe it's moving too fast for the physics collision to pick up.
in this case you might try to set CCD on for both physical objects (elevator and player).
regards,
Thanks for answering me Helghast...
I put pX_setccd ( 1 ); in the while loops of my player and my lift ... and slowed the speed of the elevator down to 0.5 but still the same thing happening !
I don't know how to fix this...
