Grabbing Objects from a Table IF

Help and Feedback Scripting Support
#42

I would also like to point out that Rig is equal to false. Let me know if you are trying to retrieve the index name (ex. Rig2)

#43

I do need the name of the index, because for example if Rig2 is false, and it’s chosen I’ll need it’s name to reference it further in the script

#44

that’s good for his use case. it’s the same as what my module is doing, just generalized with functions

#45

I figured. Here is a better way to achieve this, my apologies.

local UsedCharacters = {
    ["Rig1"] = false,
    ["Rig2"] = true,
    ["Rig3"] = false,
    ["Rig4"] = false
}
local function getRandomRig()
    local NewTable = {}
    for i,v in pairs(UsedCharacters) do
        if v==false then NewTable[#NewTable+1]=i end
    end
    return NewTable[math.random(1,#NewTable)
end

local Rig = getRandomRig()
print(Rig) -- could be either Rig1, Rig3, or Rig4

I whipped something up! I also put some comments explaining everything. Hope this helps! I also recommend you store the RigContainer in a Module script in ServerStorage, and maybe create a Module that helps you interact with the RigContainer throughout your scripts so it will be much easier for you.

--> Services
local Players = game:GetService("Players")

--> Variables
local RigContainer = { 
	["Rig1"] = false,
	["Rig2"] = false,
	["Rig3"] = false,
	["Rig4"] = false,
	["Rig5"] = false,
	["Rig6"] = false, 
}

--> Functions
--[[
This helper function simply gets all the Indexs that have the value of false and returns it in a new table, not the original
]]
local function getRigs()
	local Rigs = { }
	
	for Index, Value in pairs(RigContainer)do
		if(not Value)then
			table.insert(Rigs, Index)
		end
	end
	
	return Rigs
end


--[[
Get thes available rigs using the helper function, then gets a random rig that is available. 
Then gets that Index/Rig from the original table and sets its value as the Player
]]
Players.PlayerAdded:Connect(function(Player)
	local Rigs = getRigs()
	
	if(#Rigs > 0)then
		local randomRig = Rigs[math.random(1, #Rigs)]

		RigContainer[randomRig] = Player

		print(Player.Name.." now owns rig "..randomRig)
	end
end)

--[[
Loops through everything in the original table and checks if any of the values equal to the player, if it does it will be set to false.
]]

Players.PlayerRemoving:Connect(function(Player)
	for Key, Value in pairs(RigContainer)do
		if(Value == Player)then
			RigContainer[Key] = false
		end
	end
end)
