Lua set ghost mode in npc, is possible?

[roriscrave]

tfs 1.3 8.6
I'm creating a fight npc, after talking to him, you will fight with him.
my idea is after talking, the npc will enter ghost mode (like GM), and summon a monster with the same appearance as the NPC, for the player to fight.

but I'm not able to use the set ghost function for npc, is it possible?

quest/npc1.lua:17: attempt to call method 'setGhostMode' (a nil value)

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid) npcHandler:onCreatureAppear(cid) end
function onCreatureDisappear(cid) npcHandler:onCreatureDisappear(cid) end
function onCreatureSay(cid, type, msg) npcHandler:onCreatureSay(cid, type, msg) end
function onThink() npcHandler:onThink() end

local function creatureSayCallback(cid, type, msg)
    if not npcHandler:isFocused(cid) then
        return false
    end
    
    if npcHandler.topic[cid] == 0 then
        if msgcontains(msg, "fight") then
            Npc():setGhostMode(true)
            npcHandler:say("Lets fight!", cid)
            npcHandler.topic[cid] = 1           
        end
    end
    return true
end

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())

setGhostMode is a Player only thing, my tip is to teleport it elsewhere (where nobody can see it) and then bring it back

Quick idea:
Just replace the NPC with Monster named same as NPC (when player start fight), make onKill/onDeath script and after defeat this monster, spawn NPC on his place again.
Don't forget to set spawn in RME (map editor) to 0 to prevent spawning double NPC.

if i use Npc():remove() i need to put in map editor 0 or not?

Yes of course, it will spawn anyway if you remove him after X seconds (in RME spawntime/interval).
You always can test it manually by doing that and wait for him to spawn
