still can;t get it to work even with replacing my code and using your code

well i need it to activate after round 6.
so i need the code which can detected when the round is over.
i should be able to do the rest with my own code

i tried this but it doesn't seem to be working

local RoundCount
function AVMS.StartVote()
RoundCount = RoundCount + 1
if RoundCount == 6 then
AVMS.StartVote()
RoundCount = 0
end
end
hook.Add("TTTEndRound", "AVMS.StartVote", AVMS.StartVote )

This is the server-side code i have at the moment only set to 3 rounds for testing

local extendtime = 0 -- Extend Map for x Minutes
local retry = 0 -- Retrys if nobody voted
local minvoteneed = 0.60 -- In percent
local maxextend = 0 -- Maximum Extend do -1 to deactivate
local minvotes = 6 -- How many maps should be in the vote
local rocksneeded = 0.6 -- in % how many rockvotes are needed to force a mapvote

local RoundCount
function AVMS.StartVote()
RoundCount = RoundCount + 1
if RoundCount == 3 then
AVMS.StartVote()
RoundCount = 0
end
end
hook.Add("TTTEndRound", "AVMS.StartVote", AVMS.StartVote )

i think it;s a good idea as along as you can do ti with special weapons

i am currently in the middle of coding a TTT non - fretta end of map voting system in my spare time and i need the "End of Round  Code" in TTT but i am far too busy to have a look for it myself does any one know this?

Also i will make this public and hopefully may be added to TTT as an alternative voting system :D
