if isInRange(ppos, arena.frompos, arena.topos) then

Aqui está dando erro nessa linha <a nil value>

Mande o erro completo ...

verifique se configurou aqui corretamente :

local arena = {
  frompos = {x = 1041, y = 985, z = 9},
  topos = {x = 1052, y = 991, z = 9},
  exitpos = {x = 1038, y = 988, z = 8}
}

Consegui arrumar.. uma dúvida, teria como adaptar ele pra monstros também? Porque foi o único método que achei para ter a arena novamente no meu servidor. TFS 1.1... coloquei ele sem o uso de alavanca e tals, e funcionou.

Adaptar esse não, teria como eu fazer outro, só falar como quer, que quandro sobrar um tempo pra scriptear eu faço.

Muito bom! Bem formulado =)

Adaptar esse não, teria como eu fazer outro, só falar como quer, que quandro sobrar um tempo pra scriptear eu faço.

é o básico, se o player morrer na área definida(para monstros)\/ ele não irá perder nem loot, nem xp, nada, como se tivesse morrendo na arena mesmo, e sendo teleportado para uma pos específica. Só que no TFS 1.1 não funciona aquela parada de No-PVP / PVP

local arena = {

frompos = {x = 1041, y = 985, z = 9},

topos = {x = 1052, y = 991, z = 9},

exitpos = {x = 1038, y = 988, z = 8}

}
