Bruh 5$ aint worth for things that can literally be done in a couple lines, not to mention that 3 of the 4 things you listed (and who knows how much more) can easily be set up and used with the essentials plugin.
To avoid anyone to get ripped off, I left some skripts below, though I've also left a link of the essentials plugin (Click Here)
# AFK SKRIPT
# Note: This just teleports the player to a location. If you don't want this, remove lines 4 through 13 and use essentials
command /setafklocation:
permission: AFK.Set
trigger:
set {AFKLocation} to location of player
send "&d[AFK] &5Location Set!"
command /afk:
trigger:
teleport player to {AFKLocation}
send "&d[AFK] &5You are in the AFK location!"
# SPAWN SKRIPT
command /setspawnlocation:
permission: Spawn.Set
trigger:
set {Spawn} to location of player
send "&e[Spawn] &6Location Set!"
command /spawn:
trigger:
teleport player to {Spawn}
send "&e[Spawn] &6You've been teleported to spawn!"
# BROADCAST SKRIPT
command /broadcast <text>:
permission: Broadcast.Command
trigger:
broadcast "&c&l[BROADCAST] &e%arg-1%"
