How to find triple args with string.sub()?
So I am trying to make a command bar, and one of the commands is !givecash <plr>, <amo>. Whenever you press the ReturnEnter it should fire the event. Now while there is no problem with that, I do have a problem finding the amount of cash they would like to give the player. It should like something like this in the command bar: !givecash suspectshot108 515000. So my question is how do I find the amount? I know I can find the player with string.sub() and amount with string.sub() and awhile that is working I am lost on a way to get the amount.
LocalScript: Some code is taken out
if(string.sub(CommandLine.Text,1,10)) == string.lower("!givecash ") then
local target = game.Players:FindFirstChild(string.sub(CommandLine.Text,11))
local ammount = string.sub(CommandLine.Text,12)
print(target,ammount)
game:GetService("ReplicatedStorage").AdminEvents["CE"]:FireServer(target)
end

you could add up the amount of characters from the command prefix to the player name, so you can use string.sub() to sub the string in that amount.
local message = "!givecash EXpodo1234ALT 1000" -- lets say this is the message
local totalsub = 11 -- 11 since the prefix is 11 characters
local players = {"EXpodo1234ALT"} -- maybe just say this was the array that :GetPlayers() returned
local subprefix = string.sub(message,totalsub)
for i,v in pairs(players) do
if string.match(subprefix,v) then -- if it finds the plr name inside the string
local amount = string.len(v) -- gets the amount of characters in the name
totalsub = totalsub + (amount+1) -- adds it up
break -- breaks the loop
end
end
local AmountOfMoney = string.sub(message,totalsub,100)
print(AmountOfMoney) -- prints "1000"
workspace.NumberValue.Value = workspace.NumberValue.Value + AmountOfMoney -- example
also why I did (amount+1) is because theres a space between the name and amount.
Finished Script
game.Players.PlayerAdded:Connect(function(player)
player.Chatted:Connect(function(message)
if string.match(message,"!givecash ") then
local totalsub = 11
local players = game.Players:GetPlayers()
local subprefix = string.sub(message,totalsub)
for i,v in pairs(players) do
if string.match(subprefix,v.Name) then
local amount = string.len(v.Name)
totalsub = totalsub + (amount+1)
local amountofmoney = string.sub(message,totalsub,100)
v.leaderstats.Cash.Value = v.leaderstats.Cash.Value + amountofmoney -- if you had a leaderstats called "Cash"
break
end
end
end
end)
end)

I made a system for trading using the chat with gmatch. I pulled the core of my code and used a textbox as a "CommandLine"
I put an example on my ScriptingHelpers Place(Uncopylocked) Roblox Place
THIS WILL NOT WORK IN A LOCAL SCRIPT You need to setup an event
script.Parent.FocusLost:Connect(function()
local words = {}
local msg = script.Parent.Text
for v in msg:gmatch("[^ ]+") do
table.insert(words, v)
end
if #words == 3 then
if words[1] == "!givecash" then
if game.Players:FindFirstChild(words[2]) and tonumber(words[3]) then
game.Players[words[2]].Amount.Value = game.Players[words[2]].Amount.Value + words[3]
script.Parent.Text = ""
end
end
end
end)
