[gritness]

Hey All ,

like in topic, how to setup offline training rate?
On my server skill rate is x30. I want to change offline training rate for skill to x6 so 20% of normal value.

What parametr can i setup for do this changes? Bellow You can see my offlinetraining.lua :

function onLogin(player)
local lastLogout = player:getLastLogout()
local offlineTime = lastLogout ~= 0 and math.min(os.time() - lastLogout, 86400 * 21) or 0
local offlineTrainingSkill = player:getOfflineTrainingSkill()
if offlineTrainingSkill == -1 then
player:addOfflineTrainingTime(offlineTime * 1000)
return true
end

player:setOfflineTrainingSkill(-1)

if offlineTime < 600 then
player:sendTextMessage(MESSAGE_EVENT_ADVANCE, "You must be logged out for more than 10 minutes to start offline training.")
return true
end

local trainingTime = math.max(0, math.min(offlineTime, math.min(43200, player:getOfflineTrainingTime() / 1000)))
player:removeOfflineTrainingTime(trainingTime * 1000)

local remainder = offlineTime - trainingTime
if remainder > 0 then
player:addOfflineTrainingTime(remainder * 1000)
end

if trainingTime < 60 then
return true
end

local text = "During your absence you trained for"
local hours = math.floor(trainingTime / 3600)
if hours > 1 then
text = string.format("%s %d hours", text, hours)
elseif hours == 1 then
text = string.format("%s 1 hour", text)
end

local minutes = math.floor((trainingTime % 3600) / 60)
if minutes ~= 0 then
if hours ~= 0 then
text = string.format("%s and", text)
end

if minutes > 1 then
text = string.format("%s %d minutes", text, minutes)
else
text = string.format("%s 1 minute", text)
end
end

text = string.format("%s.", text)
player:sendTextMessage(MESSAGE_EVENT_ADVANCE, text)

local vocation = player:getVocation()
local promotion = vocation:getPromotion()
local topVocation = not promotion and vocation or promotion

local updateSkills = false
if table.contains({SKILL_CLUB, SKILL_SWORD, SKILL_AXE, SKILL_DISTANCE}, offlineTrainingSkill) then
local modifier = topVocation:getAttackSpeed() / 1000
updateSkills = player:addOfflineTrainingTries(offlineTrainingSkill, (trainingTime / modifier) / (offlineTrainingSkill == SKILL_DISTANCE and 4 or 2))
elseif offlineTrainingSkill == SKILL_MAGLEVEL then
local gainTicks = topVocation:getManaGainTicks() * 2
if gainTicks == 0 then
gainTicks = 1
end

updateSkills = player:addOfflineTrainingTries(SKILL_MAGLEVEL, trainingTime * (vocation:getManaGainAmount() / gainTicks))
end

if updateSkills then
player:addOfflineTrainingTries(SKILL_SHIELD, trainingTime / 4)
end

return true
end
