Hello, so I'm trying to make something that when you look at yourself or another player it will show they're health and mana stats, it works fine if I look at myself or another player but if I try to look at anything else I get boolean error in console because of line:

Lua: 
local health = (getCreatureHealth(thing.uid) / 1000)

I assume cuz it's trying to get the stats from the tile or item that I'm looking at, so how do I stop that and make the script only show this if the creature i'm looking at is a player?

here's the full script:

Lua: 
function onLook(cid, thing, position, lookDistance)
   local info = ""
   local health = (getCreatureHealth(thing.uid) / 1000)
   local maxhealth = (getCreatureMaxHealth(thing.uid) / 1000)
   local mana = (getPlayerMana(thing.uid) / 1000)
   local maxmana = (getPlayerMaxMana(thing.uid) / 1000)

   if isPlayer(thing.uid) then
       info = "".. getPlayerName(thing.uid) .." has ".. math.ceil(health) .."k/".. math.ceil(maxhealth) .."k health and ".. math.ceil(mana) .."k/".. math.ceil(maxmana) .."k mana!"
       doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, info)
       doCreatureSay(cid, info, TALKTYPE_MONSTER_SAY, false, cid, getThingPos(thing.uid))
   end
return true
end

They're all inside same table so you must use target instead of stats.target xd

I did test this script and it did work.
Lua: 
function onLook(cid, thing, position, lookDistance)
    local target = getTopCreature(position).uid
    if isPlayer(target) then
        local info = ""
        local health = (getCreatureHealth(target) / 1000)
        local maxhealth = (getCreatureMaxHealth(target) / 1000)
        local mana = (getPlayerMana(target) / 1000)
        local maxmana = (getPlayerMaxMana(target) / 1000)
        info = "".. getPlayerName(target) .." has ".. math.ceil(health) .."k/".. math.ceil(maxhealth) .."k health and ".. math.ceil(mana) .."k/".. math.ceil(maxmana) .."k mana!"
        doPlayerSendTextMessage(cid...

add this to the script and then change "thing.uid" to "target"
Lua: 
local target = getTopCreature(position)

Edit:
test this script
Lua: 
function onLook(cid, thing, position, lookDistance)
    local target = getTopCreature(position)
    if isPlayer(target) then
        local info = ""
        local health = (getCreatureHealth(target) / 1000)
        local maxhealth = (getCreatureMaxHealth(target) / 1000)
        local mana = (getPlayerMana(target) / 1000)
        local maxmana = (getPlayerMaxMana(target) / 1000)
        info = "".. getPlayerName(target) .." has ".. math.ceil(health) .."k/".. math.ceil(maxhealth) .."k health and ".. math.ceil(mana) .."k/".. math.ceil(maxmana) .."k mana!"
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, info)
        doCreatureSay(cid, info, TALKTYPE_MONSTER_SAY, false, cid, getThingPos(target))
    end
    return true

Thanks, but still having same error, I guess it returns the same result as thing.uid(?)

Lua: 
function onLook(cid, thing, position, lookDistance)
    local stats = {
        info = "",
        target = (getTopCreature(position).uid),
        health = (getCreatureHealth(target) / 1000),
        maxhealth = (getCreatureMaxHealth(target) / 1000),
        mana = (getPlayerMana(target) / 1000),
        maxmana = (getPlayerMaxMana(target) / 1000)
    }

    if isPlayer(stats.target) then
        stats.info = "".. getPlayerName(stats.target) .." has ".. math.ceil(stats.health) .."k/".. math.ceil(stats.maxhealth) .."k health and ".. math.ceil(stats.mana) .."k/".. math.ceil(stats.maxmana) .."k mana!"
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, stats.info)
        doCreatureSay(cid, stats.target, TALKTYPE_MONSTER_SAY, false, cid, getThingPos(stats.target))
    end

return true
end

you have to change the getCreatureHealth(target) to getCreatureHealth(stats.target) and all the other aswell.
so the functions know where the variable/table is located

example:
Lua: 
local stats = {
        info = "",
        target = (getTopCreature(position).uid),
        health = (getCreatureHealth(stats.target) / 1000),
        maxhealth = (getCreatureMaxHealth(stats.target) / 1000),
        mana = (getPlayerMana(stats.target) / 1000),
        maxmana = (getPlayerMaxMana(stats.target) / 1000)
    }

        doCreatureSay(cid, info, TALKTYPE_MONSTER, false, cid, getCreaturePosition(target))
    end
    return true
end

Edit:
Updated the script to work whitout any errors

oh I see, I should have made the config inside the function and not outside xd

it also works like this:

Lua: 
    local target = getTopCreature(position).uid
    if isPlayer(target) then
        local stats = {
            info = "",
            health = (getCreatureHealth(target) / 1000),
            maxhealth = (getCreatureMaxHealth(target) / 1000),
            mana = (getPlayerMana(target) / 1000),
            maxmana = (getPlayerMaxMana(target) / 1000)
        }
    stats.info = "".. getPlayerName(target) .." has ".. math.ceil(stats.health) .."k/".. math.ceil(stats.maxhealth) .."k health and ".. math.ceil(stats.mana) .."k/".. math.ceil(stats.maxmana) .."k mana!"
    doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, stats.info)
    doCreatureSay(cid, target, TALKTYPE_MONSTER_SAY, false, cid, getThingPos(target))
    end

thanks <3

well since you only want the text to show if there is a player then you should check if its a player first and then make the calculations because if its not a player then there is no reason to calculate/assign values, and it will throw the error since the functions require a player uid/cid.

Im glad you got it to work :)
