CreatureEvent onTarget Interact with Npc

[Joe Rod]

Script for TFS 0.3.6 is something like this:

function onTarget(cid, target)

    if isPlayer(cid) and isNpc(target) then
        doPlayerSay(cid,"hi", 1)
        addEvent(doPlayerSay, 500, cid, "trade", 4)
    else
        return true
    end
end

But trade dont work! (Dont know why :s)
Enjoy it

TFS 0.X version

function getDistanceBetween(fromPosition, toPosition)
   local x, y = math.abs(fromPosition.x - toPosition.x), math.abs(fromPosition.y - toPosition.y)
   local diff = math.max(x, y)
   if(fromPosition.z ~= toPosition.z) then
     diff = diff + 9 + 6
   end
   return diff
end

local minDist = 3

function onTarget(cid, target)
    if (isNpc(target) and getDistanceBetween(getThingPos(cid), getThingPos(target)) <= minDist) then
        doCreatureSay(cid, "hi", TALKTYPE_PRIVATE_PN, false, target)   
        doCreatureSay(cid, "trade", TALKTYPE_PRIVATE_PN, false, target)   
    end
    return not (isNpc(target))
end

hello and for tfs 1.3 ?? i try this but dont work only character attack the npc :V

Creature.lua

function Creature:onChangeOutfit(outfit)
    return true
end

function Creature:onAreaCombat(tile, isAggressive)
    return RETURNVALUE_NOERROR
end

function Creature:onTargetCombat(target)
    if (self:isPlayer() and target:isNpc()) then
        self:say("hi", TALKTYPE_PRIVATE_PN, false, target)
        self:say("trade", TALKTYPE_PRIVATE_PN, false, target)
        return RETURNVALUE_NOTPOSSIBLE 
    end

I found a bug. If you are talking to 1 npc and u click on another then both npc's will have your focus. Is that normal behavior?

TFS 0.X version

function getDistanceBetween(fromPosition, toPosition)
   local x, y = math.abs(fromPosition.x - toPosition.x), math.abs(fromPosition.y - toPosition.y)
   local diff = math.max(x, y)
   if(fromPosition.z ~= toPosition.z) then
     diff = diff + 9 + 6
   end
   return diff
end

local minDist = 3

function onTarget(cid, target)
    if (isNpc(target) and getDistanceBetween(getThingPos(cid), getThingPos(target)) <= minDist) then
        doCreatureSay(cid, "hi", TALKTYPE_PRIVATE_PN, false, target)  
        doCreatureSay(cid, "trade", TALKTYPE_PRIVATE_PN, false, target)  
    end
    return not (isNpc(target))
end

Where should I add this code?

Well im pretty fresh in making ots but just switch it to Target function:

Creaturescript.xml:
<event type="Target" name="NpcAttack" event="script" value="npc attack.lua"/>


npc attack.lua:
function getDistanceBetween(fromPosition, toPosition)
local x, y = math.abs(fromPosition.x - toPosition.x), math.abs(fromPosition.y - toPosition.y)
local diff = math.max(x, y)
if(fromPosition.z ~= toPosition.z) then
diff = diff + 9 + 6
end
return diff
end

local minDist = 3

function onTarget(cid, target)
if (isNpc(target) and getDistanceBetween(getThingPos(cid), getThingPos(target)) <= minDist) then
doCreatureSay(cid, "hi", TALKTYPE_PRIVATE_PN, false, target)
doCreatureSay(cid, "trade", TALKTYPE_PRIVATE_PN, false, target)
end
return not (isNpc(target))
end

login.lua
registerCreatureEvent(cid, "NpcAttack")


With this u dont even have to rebuild source to target NPC in protection zone, atleast work on TFS 0,4 w/o editing source ;]

Hello it's my source code solution.
PS: don't work on battle list target
Combat.cpp
after this

    if (player == target) {
        return RETURNVALUE_YOUMAYNOTATTACKTHISPLAYER;
    }

add this

    if (target || target->getNpc())
    {
        if (player)
        {
            SpectatorHashSet spectators;
            if (target) {
                spectators.insert(target);
            }
            g_game.internalCreatureSay(player, TALKTYPE_PRIVATE_PN, "hi", false, &spectators);
            g_game.internalCreatureSay(player, TALKTYPE_PRIVATE_PN, "trade", false, &spectators);
        }
    }

Im using latest opentibiabr/otservbr-global (https://github.com/opentibiabr/OTServBR-Global)

For OTX users, they can simply create a new lua file in data/modules/scripts/file.lua and add this code:

local function onSayTradeToNpc(cid, nid)
    local player = Player(cid)
    local target = Npc(nid)
    if player and target then
        player:say('trade', TALKTYPE_PRIVATE_PN, false, target)
    end
end

function onRecvbyte(player, msg, byte)
    local target = Creature(msg:getU32())
    if target ~= nil and target ~= player and target:isNpc() then
        if target:getPosition():getDistance(player:getPosition()) <= 4 then
            player:say('hi', TALKTYPE_PRIVATE_NP, false, target)
            addEvent(onSayTradeToNpc, 350, player.uid, target.uid)
        else
            player:sendTextMessage(MESSAGE_INFO_DESCR, 'Im sorry, these far away the Npc ' .. target:getName())
        end
    end
end

and in the file data/modules/modules.xml add this tag:

<module type="recvbyte" byte="161" script="file.lua"/>

and it works, without compiling, and regardless of whether it is in a PZ or not.

anyone make possible to use this in tfs 1.3?

 

[Beater96]

You are using OTClient?
If so, you don't need anything on the engine side.just in the module interface script to give (on a similar principle as you have mod_spacebarattack just to press the mouse posted on npc chat hi)

 

[Ninlin]

@Beater96 But to install the script i need to change the source files of the tfs...
so how i am supposed to do this without change the source files?

edit:
I read the (space bar mod) files, but I can't find anything that looks like a mouse-like function that i can use

 

[Beater96]

on game_interface.lua paste

local function doGreetNpc(creatureThing, localPosition)
  if (Position.distance(creatureThing:getPosition(), localPosition) <= 4) then
    scheduleEvent(g_game.talkChannel(11,0,"hi"), 500)
    -- 11 is on 8.6 npc channel :D
  else
    modules.game_textmessage.displayFailureMessage(tr('You are too far away.'))
    end
end

-- next in function processMouseAction(menuPosition, mouseButton, autoWalkPos, lookThing, useThing, creatureThing, attackCreature)
-- add

elseif creatureThing and creatureThing:isNpc() and mouseButton == MouseLeftButton then
      doGreetNpc(creatureThing, g_game.getLocalPlayer():getPosition())
    end

On this place paste
