So, the script below should work, but i dont have a "bsp 1" in the map? I want to change the bsp from day/night by killing the biped "biped1". Can Somebody help?

(script continuous switching
(if (= (unit_get_health biped1) 0)
(begin
(switch_bsp bsp 1)
)
)
)
(script continuous sync_part
(if (= (unit_get_health biped1) 0)
(begin
(object_create_anew biped1)
(sleep 30)
)
)
)
