every time she laughs she advances one stage out of 5, after the fifth laugh lock the right door, if she laughs again she moved back to stage 4 out of 5, she never moves back unless she is already at stage 5, she can be countered while only counting laughs, dont need no cameras

Basically:

Laugh = Move

If Freddy is on the camera to the right of your office (6B), close the door. 

Otherwise, do nothing.
