How would I change the characters in a value, like if i have _c8_ change the _ to a letter?
Namee = script.Parent.Namee
Nameo = script.Parent.Nameo
--Characters Here:
local characters = {"_", "q", "w", "e", "r", "t", "y", "u", "i", "o", "p", "a", "s", "d", "f", "g", "h", "j", "k", "l", "z", "x", "c", "v", "b", "n", "m", "Q", "W", "E", "R", "T", "Y", "U", "I", "O", "P", "A", "S", "D", "F", "G", "H", "J", "K", "L", "Z", "X", "C", "V", "B", "N", "M", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"}
--Length Here:
local charLength = 1
local cache = {}
--/CONFIGURATION--
local Ui = script.Parent.Parent.ScrollingFrame
--You Will See Random Generated Word In Output Window
--To Start It Disable This Script And Enable
while true do wait()
local word = ""
for i = 1, charLength do
local randNum = math.random(1, #characters)
word = word .. characters[math.random(1, #characters)] .. characters[math.random(1, #characters)] .. characters[math.random(1, #characters)] .. characters[math.random(1, #characters)]
print(word)
Nameo.Text = word
wait()
word = ""
end
local Players = game:GetService("Players")
local cache = {}
function GetUserIdFromUsername(name)
-- First, check if the cache contains the name
if cache[name] then return cache[name] end
-- Second, check if the user is already connected to the server
local player = Players:FindFirstChild(name)
if player then
cache[name] = player.UserId
return player.UserId
end
-- If all else fails, send a request
local id
pcall(function ()
id = Players:GetUserIdFromNameAsync(name)
end)
cache[name] = id
return id
end
if (GetUserIdFromUsername(Nameo.Text)) == nil then
Namee.Text = ("Not Taken")
local addtolist = Instance.new("TextLabel")
addtolist.Parent = Ui
addtolist.BackgroundTransparency = 1
addtolist.Size = UDim2.new(5, 0, 5, 0)
addtolist.Text = Nameo.Text
script.Parent.Image = "rbxassetid://891981050"
else
Namee.Text = (GetUserIdFromUsername(Nameo.Text))
script.Parent.Image = "http://www.roblox.com/Thumbs/Avatar.ashx?x=200&y=200&Format=Png&userid="..(GetUserIdFromUsername(Nameo.Text))
end
end
I have tried using strings but it didn't work, and I don't even know if there is a way. Nameo is the value because it comes back like i said in the title, sometimes.
I added this below Nameo.Text = word and above wait()
if Nameo.Text == string.sub(1,1) == "_" then Nameo.Text = "null" end if Nameo.Text string.sub(4,4) == "_" then Nameo.Text = "null" end
It didn't work...

Luckily for you, Lua provides a method for this. You can use string.gsub, the first argument is the string, the second is the thing you want to replace in the string, and the third is is what you want to replace it with.
Example:
local s = "_Hello_"; s = string.gsub(s, "_", "!"); print(s);
The result is --> !Hello!
EDIT: An optional fourth argument also allows you to specify how many times the function is allowed to replace something.
Example:
local s = "_Hello_"; s = string.gsub(s, "_", "!", 1); print(s);
The result is --> !Hello_

what if i only want it to be removed in certain areas like _c_8 instead of the thing in the title? i want one underscore to be removed instead of both, like it would be !c_8 according to yours with what i want JohnerDev 27 — 5y

Why not just use different symbols? So instead _ being the symbol that gets replacing, you could use * as the symbol that gets replaced, so *c_8 would turn into !c_8 davidgingerich 603 — 5y

Because its needed to generate the names, because some names have underscores JohnerDev 27 — 5y

That'd just replace all the underscores with the letter m. davidgingerich 603 — 5y

yeah but i only want it to replace the two on the outside _jd_ for example those 2 i want to replace with m because it doesnt matter since that account probably already exists JohnerDev 27 — 5y

ok thanks JohnerDev 27 — 5y

What about the last one _oi_ JohnerDev 27 — 5y

There is 2 underscores and this would only get rid of one. JohnerDev 27 — 5y

Calling the function like string.gsub("_oi_", "_", "m", 1) would return "moi_" davidgingerich 603 — 5y

So basically I want the underscores to only get replaced at certain spots, because lets say i had _9__ as the random thing that would go to m9mm whilst i would like it to be m9_m not that, or lets say t_9_ that would be tm9m or tm9_ but i would like t_9m in that case, so is there even a way to do this?

But you don't know the exact characters before hand JohnerDev 27 — 5y

If you have Discord, you can PM me, I'm the the SH Discord server, and my name is the same one I have on here. In the meantime, would you be so kind to accept this as the correct answer? I also answered a question you had previous to this one which you never got back to. davidgingerich 603 — 5y
