[SOLVED]Is there any way to get every nth number? [closed]
if CurrentRound == 10 or CurrentRound == 20 or CurrentRound == 30 or CurrentRound == 40 or CurrentRound == 50 then -- etc..
-- Do something
end
I'm wondering if there's a cleaner way of doing this. Any help will be appreciated!
EDIT: I made it slightly cleaner.
local SpecialRounds = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100}
for i,v in pairs(SpecialRounds) do
if CurrentRound == v then
-- Do something
end
end
Let me know if there's an even cleaner way of doing this. Thanks!

Generally with this kind of problem I suggest an array. Then use a function to loop through the array and see if the item is in that array. Here is an example:
local specialRounds = {
10,
20,
30,
40,
50
} -- and so on
local function checkRound(currentRound, rounds)
for i,v in pairs(rounds) do
if currentRound == v then
return true
end
end
return false -- because return breaks out of a function, if the return true is never reached, this function will return false
end
-- here I will put an example
local round = 30
if checkRound(round, specialRounds) then
--code
end
If you are wanting to only check if the round is a multiple of ten than you can simply use the modulus % operator. It will divide the number by whatever number you choose and return the remainder. This means that if you have a remainder of 0 the number is divisible by ten. Here is an example:
local currentRound = 15
if currentRound % 10 == 0 then
-- code
end
I hope this helps and have a great day scripting! Edit: What theking48989987 was going for was incrementing by ten. I just wanted to clarify so that people understood his method a little better. I will also use a function so that it can be used as many times as you might want. Example of method:
local highestLevel = 100
local function checkRound(currentRound, maxLevel)
for i = 10, maxLevel, 10 do -- growing by ten every loop and I am starting at ten because that is the first value you check in your example
if currentRound == i then
return true -- is a multiple of ten because we are growing by ten
end
end
return false -- same concept as in the function above
end
local currentRound = 20
if checkRound(currentRound, highestLevel) then
-- code
end
I hope this helps clarify what he meant. Have a great day scripting!
It seems like each 'special round' is one which is a multiple of ten (or every tenth round), so you can just check whether CurrentRound % 10 == 0 evaluates to true.
i.e.
if CurrentRound % 10 == 0 then
--Code
end
if you are using alot of rounds, you can use a numeric for loop instead of a generic for loop.
local currentround = 57
for i = 0,100 do
if currentround = i then
...
end
end
come to think of it, this is one of the few times numeric for loops are superior to generic for loops lol.
