Little question about loops :P

[Hermes]

Hi there.

I have one, simple question, to improve my scripting skills.

There's table:

local table = {
1 = "first option",
2 = "second option",
3 = "third option",
10 = "tenth option"
}

And I want to make a loop for randomizer, so:
with randomizer

math.random(1,10)

as a first number in table I want script to assign text to those number (ofc number depends on randomizer).

Yeah, I know I have missed some of my LUA lessons with loops xD

Thanks in advance!

Hermes

I realy don't know what you try there, rofl.

First, your table has errors.

local t = {
    [1] = "first option",
    [2] = "second option",
    [3] = "third option",
    [10] = "tenth option"
}

Now, we could use this function to get a random value from tables:

function table.irand(t)
    -- Function by Colandus
    return t[math.random(1, #t)]
end

This one would only give you 1, 2, 3 and NOT 10. Because just as if you'd have used the loop "for k,v in ipairs(t) do", it would only have showed those 3.

Now, to solve this we could use another function:

function table.rand(t)
    -- Function by Colandus
    local tmp = {}
    for _, v in pairs(t) do
        table.insert(tmp, v)
    end
    return table.irand(tmp)
end

Now, you can use table.rand(t) to get a random value from a table.

But how to convert this to loop usage?

local table = {
[1] = "first text",
[2] = "second text",
[3] = "third text"
)

local randomizer = math.random(1,3)

if randomizer == 1 then
doPlayerSay(cid, "first text")
elseif randomizer == 2 then
doPlayerSay(cid, "second text")
elseif randomizer == 3 then
doPlayerSay(cid, "third text")
end

 

[Shawak]

local text = ""
chance = math.random(1,3)

if chance = 1 then
 text = "first text"
elseif chance = 2 then
 text = "second text"
elseif chance = 3 then
 text = "third text"
end
   doPlayerSay(cid,text)

I am sure that you can use it so :thumbup:.


EDIT:

local table = {
[1] = "first text",
[2] = "second text",
[3] = "thirrd text"
}

local text = table[math.random(1, 3)]
doPlayerSay(cid, text)

This edit not by me.

Yeah, but my method is omfg boring for alot of messages, but second idea is nice, i thought that loop will be better but I failed XD, thanks!

 

[Shawak]

No Problem :thumbup:.

I already showed you how to do it. Just read my post properly.

 

[chojrak]

local table = {
[1] = "first text",
[2] = "second text",
[3] = "thirrd text"
}

local text = table[math.random(1, #table)]
doPlayerSay(cid, text)

It`ll automaticaly detect lenght of table. ;P

 

[Shawak]

local table = {
[1] = "first text",
[2] = "second text",
[3] = "thirrd text"
}

local text = table[math.random(1, #table)]
doPlayerSay(cid, text)

It`ll automaticaly detect lenght of table. ;P

local t = {
[1] = "first text",
[2] = "second text",
[3] = "thirrd text"
}
local tx = table[math.random(1,#t)]
doPlayerSay(cid,tx)

shorter?

[Alindane]

Changing a variable name isn't called to shorten a code. But indeed don't name your variables "table", as it would make you unabled to use table-functions (such as table.insert or w/e).

 

[Shawak]

Don't understand jokes? .

[Alindane]

Uhm, fail?

That didn't seem like a joke to me, and I bet it won't to any other person either.

 

[Shawak]

Alindane, the script work, the user is happy, and I ignore you now.

PS: Modarator's please close the theard .

Who are you to decide whether thread should be open or not? I'll ignore you as well
