Part 5 - Different kinds of missions
Monster mission
When you want a mission that's not about items, for example with killing monsters, it's not so much different than an items mission.
Only now instead of checking if a player has an item, you check if a player killed monsters.
There are functions to find out if a player has items, but there is no function to find out if a player has killed monsters, that's why you have to add storagevalues when killing the monsters, so you can check for that storagevalue in the NPC.
This can't be done in an NPC, since an NPC has no influence on what you kill, so you have to make an extra script in creaturescripts with function onKill.
For example you want a mission where someone has to kill 5 dragons and 3 dragons lords (if you want more or less monsters, you can just add or remove lines in local config).
Code:
local config = {
['dragon'] = {amount = 5, storage = 19000, startstorage = 5002, startvalue = 1},
['dragon lord'] = {amount = 3, storage = 19001, startstorage = 5002, startvalue = 1}
}
function onKill(cid, target)
local monster = config[getCreatureName(target):lower()]
if isPlayer(target) or not monster or isSummon(target) then
return true
end
if (getPlayerStorageValue(cid, monster.storage)+1) < monster.amount and getPlayerStorageValue(cid, monster.startstorage) >= monster.startvalue then
setPlayerStorageValue(cid, monster.storage, getPlayerStorageValue(cid, monster.storage) + 1)
doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, 'Task message: '..(getPlayerStorageValue(cid, monster.storage)+1)..' of '..monster.amount..' '..getCreatureName(target)..'s killed.')
end
if (getPlayerStorageValue(cid, monster.storage)+1) == monster.amount then
doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, 'Congratulations, you have killed '..(getPlayerStorageValue(cid, monster.storage)+1)..' '..getCreatureName(target)..'s and completed the '..getCreatureName(target)..'s mission.')
setPlayerStorageValue(cid, monster.storage, getPlayerStorageValue(cid, monster.storage) + 1)
end
return true
end
The startstorage is the storage from the NPC with value 1, so this means the script will start counting after accepting the mission.
The other storage, named storage, is to count the monsters.
Now in the NPC, instead of checking if a player has an item, you check for the value of the storage you use used to count the monsters.
Code:
local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}
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 storage = 5002
function creatureSayCallback(cid, type, msg)
if not npcHandler:isFocused(cid) then
return false
end
local talkUser = NPCHANDLER_CONVBEHAVIOR == CONVERSATION_DEFAULT and 0 or cid
if msgcontains(msg, "mission") then
if getPlayerStorageValue(cid, storage) == -1 then
selfSay("I have a mission for you to kill 5 dragons and 3 dragon lords, do you accept?", cid)
talkState[talkUser] = 1
elseif getPlayerStorageValue(cid, storage) == 1 then
selfSay("Did you kill 5 dragons and 3 dragon lords?", cid)
talkState[talkUser] = 1
else
selfSay("You already did the mission.", cid)
end
elseif msgcontains(msg, "yes") and talkState[talkUser] == 1 then
if getPlayerStorageValue(cid, storage) == -1 then
selfSay("Good, come back when you killed them.", cid)
setPlayerStorageValue(cid, storage, 1)
else
if getPlayerStorageValue(cid, 19000) == 5 and getPlayerStorageValue(cid, 19001) == 3 then
selfSay("Good job, here is your reward.", cid)
doPlayerAddItem(cid, 2160, 5)
doPlayerAddExp(cid, 50000)
setPlayerStorageValue(cid, storage, 2)
else
selfSay("You didn't kill them all.", cid)
end
end
talkState[talkUser] = 0
elseif msgcontains(msg, "no") and talkState[talkUser] == 1 then
selfSay("Ok then.", cid)
talkState[talkUser] = 0
end
return true
end
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
npcHandler:addModule(FocusModule:new())
