Lua What does this line mean?

What does this line mean? "setConditionParam(condition, CONDITION_PARAM_SUBID, 99)" May I remove it if I just want the potion to increase my magic level by 10 for 60 minutes?

local condition = createConditionObject(CONDITION_ATTRIBUTES)
setConditionParam(condition, CONDITION_PARAM_TICKS, 60 * 60 * 1000) -- 10 minutes
setConditionParam(condition, CONDITION_PARAM_STAT_MAGICLEVEL, 10)
setConditionParam(condition, CONDITION_PARAM_SUBID, 99)
function onUse(cid, item, fromPosition, itemEx, toPosition)
    if(not isSorcerer(cid) and not isDruid(cid)) then
        doCreatureSay(cid, "Only sorcerers and druids may drink this fluid.", TALKTYPE_ORANGE_1, cid)
        return true
    end
    if(doAddCondition(cid, condition)) then
        doSendMagicEffect(fromPosition, CONST_ME_MAGIC_RED)
        doRemoveItem(item.uid, 1)
        doCreatureSay(cid, "Your magic level increased by 10 for 60 minutes.", TALKTYPE_ORANGE_1, cid)
    end
    return true
end

No way to test but I think its there so the condition cannot be overridden with the same attributes. So lets say we have another spell which increases your mlvl. This way you can combine them

I think thats how it works (you can test)

And also allows you to manage it by checking specific conditions on player and removing them using different scripts

@mackerel is right, subid is a unique identifier for the condition so that you can find it later and alter it instead of having to interfere with the default subid and overwrite other conditions with new ones

Alright thanks a lot!

When I use this script it gives me 10 magic levels but it also decreases my shielding with 10 and I can not heal or do any spells. Where am I wrong?

local condition = createConditionObject(CONDITION_ATTRIBUTES)
setConditionParam(condition, CONDITION_PARAM_TICKS, 60 * 60 * 1000) -- 10 minutes
setConditionParam(condition, CONDITION_PARAM_STAT_MAGICLEVEL, 10)
setConditionParam(condition, CONDITION_PARAM_SUBID, 99)
function onUse(cid, item, fromPosition, itemEx, toPosition)
    if(not isSorcerer(cid) and not isDruid(cid)) then
        doCreatureSay(cid, "Only sorcerers and druids may drink this fluid.", TALKTYPE_ORANGE_1, cid)
        return true
    end
    if(doAddCondition(cid, condition)) then
        doSendMagicEffect(fromPosition, CONST_ME_MAGIC_RED)
        doRemoveItem(item.uid, 1)
        doCreatureSay(cid, "Your magic level increased by 10 for 60 minutes.", TALKTYPE_ORANGE_1, cid)
    end
    return true
end

ORIGINAL SCRIPT

local condition = createConditionObject(CONDITION_ATTRIBUTES)
setConditionParam(condition, CONDITION_PARAM_TICKS, 10 * 60 * 1000) -- 10 minutes
setConditionParam(condition, CONDITION_PARAM_STAT_MAGICLEVEL, 3)
setConditionParam(condition, CONDITION_PARAM_SKILL_SHIELD, -10)
setConditionParam(condition, CONDITION_PARAM_SUBID, 99)
function onUse(cid, item, fromPosition, itemEx, toPosition)
    if(not isSorcerer(cid) and not isDruid(cid)) then
        doCreatureSay(cid, "Only sorcerers and druids may drink this fluid.", TALKTYPE_ORANGE_1, cid)
        return true
    end
    if(doAddCondition(cid, condition)) then
        doSendMagicEffect(fromPosition, CONST_ME_MAGIC_RED)
        doRemoveItem(item.uid, 1)
        doCreatureSay(cid, "You feel smarter.", TALKTYPE_ORANGE_1, cid)
    end
    return true
end

not sure why you wouldn't be able to use spells, doesn't sound like it's an issue with this script
but as for your shield you have setConditionParam(condition, CONDITION_PARAM_SKILL_SHIELD, -10) in your script

This one looks alright OP

you should change the SUBID from 99 to something else and see if that works

if Not I would test the script on another item
