Checking if more then two values are set to true using an if statement

Help and Feedback Scripting Support
#1

The title says it all. I’m trying to use a table to see if multiple values are set to true. I’ve tried things like for _,v in pairs(table) do if v then print('Nice') end end but that didn’t work, I also tried something like if value and value2 and value3 then print('Nice') end but that also didn’t work.

#2 
local function checkValues(table)
   local v1 = false -- previous value
   
   for _, v in pairs(table) do
      if not v1 and v then -- only 1 value then
         v1 = v -- set true
      elseif v1 and v then -- 2 values then true
         return true 
      end
   end

   return false
end

Note, this returns true for 2+ values, so this includes 3, 4 etc as well. If you want to instead check that you have to use 2 values and use a 3rd value and the following code:

v1 and v2 and not v3
#3

idk the purpose of the system, but if all tables are dictionaries would be easy to check everything with one loop without having a previous V1 data.

local Dic1 = {}
Dic1[player.UserId] = true

local Dic2 = {}
Dic2[player.UserId] = false

for _, p in pairs(Players:GetPlayers()) do
	if Dic1[p.UserId] and Dic2[p.UserId] then
		print("Both are true")
	end
end
#4

I can’t get this script to function. It gives an error about my table. How would the table used here look like?

If you want to check if all the values in a table are true, you could just do this:

local sample = {true, true, true, false}
local true_count = 0
for _, v in pairs(sample) do
    if v == true then 
        true_count = true_count + 1
    end
end

if true_count == #sample then
    print("All values are true")
else
    print("Not all values are true")
end

I’m pretty sure that the code explains it all :slight_smile: .

there where two mistakes in the code. After fixing those minor mistakes the code worked. Thank you for helping!

#7

A much easier way is just to do the following:

local YourTable = {false,true,true,false}
if not table.find(YourTable, false) then
--Your code to run
else
--Your code to run if there is a false value.
end
#8

This will run even when not all of them are set to true

#9

Just remove the else part, if you do not want to do anything if one or more is false.
Like this:

local YourTable = {false,true,true,false}
if not table.find(YourTable, false) then
--Your code to run
end
