Used by the routine at Handle_Sabreman_On_Rope.
Makes Sabreman fall off the rope when something hits him (a bubble, a creature or the falling stalactite). He tumbles, with the y velocity that is in B. His x velocity is the distance that the end of the rope moved (see Rope_End_Position) and the countdown in byte 0A is set to 14. The rope is made a type 17 object again, and Sabreman is drawn, at Restore_Type_17_Object.
