NPC Quick Tip: Free Boat Travel ["/reload config"]

[J.Dre]

Thought of this when someone asked for a boat NPC in support.

"Do you want to sail to Carlin for 0 gold coins?" NO!

"Do you want to sail to Carlin for free?" YES!​

This will allow freeTravel to all players with a simple config.lua edit. It's easy to implement and looks much better in game.

freeTravel = true

npc/lib/npcsystem/modules.lua

Replace your modules with these in modules.lua:

    function StdModule.travel(cid, message, keywords, parameters, node)
        local npcHandler = parameters.npcHandler
        if(npcHandler == nil) then
            print('[Warning - ' .. getCreatureName(getNpcId()) .. '] NpcSystem:', 'StdModule.travel - Call without any npcHandler instance.')
            return false
        end

        if(not npcHandler:isFocused(cid)) then
            return false
        end

        local storage, pzLocked = parameters.storageValue or (EMPTY_STORAGE + 1), parameters.allowLocked or false
        if getConfigInfo('freeTravel') then
            parameters.cost = 0
        end
        if(parameters.premium and not isPremium(cid)) then
            npcHandler:say('I\'m sorry, but you need a premium account in order to travel onboard our ships.', cid)
        elseif(parameters.level ~= nil and getPlayerLevel(cid) < parameters.level) then
            npcHandler:say('You must reach level ' .. parameters.level .. ' before I can let you go there.', cid)
        elseif(parameters.storageId ~= nil and getPlayerStorageValue(cid, parameters.storageId) < storage) then
            npcHandler:say(parameters.storageInfo or 'You may not travel there yet!', cid)
        elseif(not pzLocked and isPlayerPzLocked(cid)) then
            npcHandler:say('First get rid of those blood stains! You are not going to ruin my vehicle!', cid)
        elseif(not doPlayerRemoveMoney(cid, parameters.cost)) then
            npcHandler:say('You don\'t have enough money.', cid)
        else
            npcHandler:say('Set the sails!', cid)
            npcHandler:releaseFocus(cid)

            doTeleportThing(cid, parameters.destination, false)
            doSendMagicEffect(parameters.destination, CONST_ME_TELEPORT)
        end

        npcHandler:resetNpc(cid)
        return true
    end

    function TravelModule.travel(cid, message, keywords, parameters, node)
        local module = parameters.module
        if(not module.npcHandler:isFocused(cid)) then
            return false
        end

        if getConfigInfo('freeTravel') then
            parameters.cost = 0
        end
      
        module.npcHandler:say('Do you want to travel to ' .. keywords[1] .. ' for ' .. parameters.cost .. ' gold coins?', cid)
        return true
    end

    function TravelModule.onConfirm(cid, message, keywords, parameters, node)
        local module = parameters.module
        if(not module.npcHandler:isFocused(cid)) then
            return false
        end

        if getConfigInfo('freeTravel') then
            parameters.cost = 0
        end
      
        local parent = node:getParent():getParameters()
        if(isPremium(cid) or not parent.premium) then
            if(not isPlayerPzLocked(cid)) then
                if(doPlayerRemoveMoney(cid, parent.cost)) then
                    module.npcHandler:say('Set the sails!', cid)
                    module.npcHandler:releaseFocus(cid)

                    doTeleportThing(cid, parent.destination, true)
                    doSendMagicEffect(parent.destination, CONST_ME_TELEPORT)
                else
                    module.npcHandler:say('You don\'t have enough money.', cid)
                end
            else
                module.npcHandler:say('First get rid of those blood stains! You are not going to ruin my vehicle!', cid)
            end
        else
            module.npcHandler:say('I\'m sorry, but you need a premium account in order to travel onboard our ships.', cid)
        end

        module.npcHandler:resetNpc(cid)
        return true
    end

    function TravelModule.bring(cid, message, keywords, parameters, node)
        local module = parameters.module
        if(not module.npcHandler:isFocused(cid)) then
            return false
        end

        if getConfigInfo('freeTravel') then
            parameters.cost = 0
        end
      
        if((isPremium(cid) or not parameters.premium) and not isPlayerPzLocked(cid) and doPlayerRemoveMoney(cid, parameters.cost)) then
            module.npcHandler:say('Set the sails!', cid)
            module.npcHandler:releaseFocus(cid)

            doTeleportThing(cid, parameters.destination, false)
            doSendMagicEffect(parameters.destination, CONST_ME_TELEPORT)
        end

        module.npcHandler:releaseFocus(cid)
        return true
    end

Here's an example travel node for NPC's:

--Travel Nodes
local travelNode = keywordHandler:addKeyword({"carlin"}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = "Do you want to sail to Carlin for " .. (getConfigInfo("freeTravel") and "free?" or "110 gold coins?")})
    travelNode:addChildKeyword({"yes"}, StdModule.travel, {npcHandler = npcHandler, premium = false, level = 0, cost = 110, destination = {x=32387, y=31820, z=6} })
    travelNode:addChildKeyword({"no"}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, reset = true, text = "We would like to serve you some time."})

Easy peasy. Done.
