How to make a money betting system?

[TimeTraveller]

I would like to know how to do that, for example, you place a command like /bet, place an amount of money that you want but that you have, and that money is discounted or doubled when you place it, randomly.

Well something like this could work i never did one such system but u need something like math.random() or some kind of function to get some random numbers

 function bet_some_money(thePlayer,CommandName,amount)
  	if source == thePlayer then  -- check for player
    	local playerMoney = getPlayerMoney(thePlayer) -- get how much money has the player who calls the command 
    	if amount ~= nil and type(amount) == "number" then  -- check if amount is not nil and also if it is a number
    		if amount <= playerMoney then  -- chek if amount is not more than all the money he has at him now 
      			takePlayerMoney(thePlayer,amount) -- take the money 
      		  local number = math.random(0,1) -- a random number also u can use a table with numbers or %
      			if number == 0 then 
        		  outputChatBox("[BET] You lose this time, maybe u have more luck next time!",thePlayer,255,104,104)
      		  elseif number == 1 then 
        		outputChatBox("[BET] You won gg man :D",thePlayer,104,255,104)
        		givePlayerMoney(thePlayer,2*amount) -- give player 2 x amount
              end
       	   end 
      	end
    end
 end

also this code is not tested!!!

function bet(player, cmd, amount)
    amount = tonumber(amount)
    if not amount or amount <= 0 then
        outputChatBox("Invalid bet amount.", player, 255, 0, 0, true)
        return
    end

    local money = getPlayerMoney(player)
    if money < amount then
        outputChatBox("You don't have enough money to make that bet.", player, 255, 0, 0, true)
        return
    end

    local win = math.random(0, 1) == 1
    if win then
        givePlayerMoney(player, amount*2)
        outputChatBox("You won your bet of $" .. amount .. "!", player, 0, 255, 0, true)
    else
        takePlayerMoney(player, amount)
        outputChatBox("You lost your bet of $" .. amount .. ".", player, 255, 0, 0, true)
    end
end
addCommandHandler("bet", bet)
