mob spawning skript

[Narratrr]

every 5 seconds in "world1":
    if {mob1count} is less than 90:
        spawn zombie at location at {location1}
        apply potion of absorption of tier 30 to last spawned zombie for 1000000 seconds
        apply potion of strength of tier 1 to last spawned zombie for 1000000 seconds
        apply potion of speed of tier 1 to last spawned zombie for 1000000 seconds
        apply potion of glowing of tier 1 to last spawned zombie for 5 seconds
        add 1 to {mob1count}

 

command /setmobspawn [<text>] [<integer>]:
    permission: op
    trigger:
        if player's world = "world1":
            set {world1%arg-1%spawn%arg-2%} to location of player
            send "&fworld 1, %arg-1%&f's spawn %arg-2%"
            send "%{world1%arg-1%spawn%arg-2%}%" to player
