falling tnt:

loop in every systetick
_timer = timer + deltatime
__if timer is more then 10 then
__timer = 0
__counting players loop
___get player position
___position y = y + 5 (move the position 5 over the player)
___place tnt:tnt_burning (burning tnt)
__select next player, end loop
_end if timer
end loop


falling steel:

the loop:

loop in every systetick
_timer = timer + deltatime
_if timer is more then 10 then
__timer = 0
__counting players loop
___get player position
___position y = y + 20 (move the position 20 over the player)
___set steel entity 1
___set steel entity 2
___set steel entity 3
___set steel entity 4
___set steel entity 5
__end if timer
_select next player, end loop
end loop

steel entity:

on activate:
_set acceleration y=-8 (make it always falling down, kinda same speed as players)
_set velocity -2
end

on step:
_get object position
_counting all objects that are within the area
__get objects propertys, will be void if its a player
__if not objects propertys exist, and object name is not "fallingsteel:steel" then (make sure the object not is punching it self)
___punch object (50 hp)
__end of if
_end counting
_if object velocity y is 0 (check if the object not are falling) then
__place steelblock
__play steelblock dig sound
__remove object
_end of if


the type="" is just an extra variable, does nothing, but makes some mobs not attacking it
