Lua if 5 players are in range then return false

[ligus]

Hello, I want to make script which returns false if there are 5 players in range

I'm trying to do it

function onCastSpell(cid, var)
    if(isInRange(getPlayerPosition(cid), {x = toPosition.x-7, y = toPosition.y-5, z = toPosition.z}, {x = toPosition.x+7, y = toPosition.y+5, z = toPosition.z})) then
        return false, doPlayerSendTextMessage(cid, MESSAGE_STATUS_SMALL, 'Sorry, not possible.'), doSendMagicEffect(getThingPos(cid), CONST_ME_POFF)
    end
    return doCombat(cid, combat, var)
end

Of course it does not work at all, this script needs to be fixed and should count players, does anyone know how can it be done?

Thanks in advance

Which tfs version are you using?

For tfs 1.0

local maxPlayers = 5

function onCastSpell(cid, var)
    local player = Player(cid)
    local specs = Game.getSpectators(player:getPosition(), false, false, 0, 7, 0, 7)
        for i = 1, #specs do
            if #specs >= maxPlayers then
            player:sendTextMessage(MESSAGE_STATUS_SMALL, 'Sorry, not possible.')
            player:getPosition():sendMagicEffect(CONST_ME_POFF)
            return false
        end
    end
        return true
enda

Try this:

local maxPlayers = 5

function onCastSpell(cid, var)
    local players = {}
    local specs = getSpectators(getCreaturePosition(cid), 7, 7, false)
        for i = 1, #specs do
            if isPlayer(specs[i]) then
                    table.insert(players, specs[i])
            end
        end
    if #players >= maxPlayers then
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_SMALL, 'Sorry, not possible.')
                doSendMagicEffect(getCreaturePosition(cid), CONST_ME_POFF)
        return false
    end
    return true
end

Thank you so much!

There is one problem because this line:

local specs = getSpectators(getCreaturePosition(cid), 7, 7, false)

counts players and NPC also, how can it be done to count players only?

Are you sure? This line should fixed that:

if isPlayer(specs[i]) then

Can you paste this under the

if isPlayer(specs[i]) then

print(getCreatureName(specs[i]))

 

[ligus]

It prints only players but when there are 5 NPC or 5 monsters then spell is blocked

Recopy the script and try it out

Hmm, still does not work

Edit:

Copy again, sorry for the tab. Idk, but the code tags fcking it up.

 

[ligus]

Perfect! Thank you!

No problem. But i think it will count you as a player in the spell, idk if you want that
Else you could do this:

if isPlayer(specs[i]) and specs[i] ~= cid then

Or just put number 6 on the max.
