i need someone to show me how to add a cooldown so if a player chooses a song....after 3 hours again someone will be able 2 choose the song....

Here, what you need is a table to keep track of player cooldowns.

...It's a tad bit hard to explain, so I'll just write it for you :S

Cooldowns = {};
NUM_MINUTES = 60*3;	--3 hours

function Music_OnGossipTalk(pUnit, event, player, pMisc)
pUnit:GossipCreateMenu(100, player, 1)
pUnit:GossipMenuAddItem(0, "*Rock*", 1, 0)
pUnit:GossipMenuAddItem(0, "*holy life -srinty bpeers*", 2, 0)
pUnit:GossipMenuAddItem(0, "*Drums*", 3, 0)
pUnit:GossipMenuAddItem(0, "*MURLOC*", 4, 0)
pUnit:GossipMenuAddItem(0, "Wooot? Illidan??", 5, 0)
pUnit:GossipSendMenu(player)
end


function Music_OnGossipSelect(pUnit, event, player, id, intid, code, pMisc)

if Cooldowns[player:GetName()] and ( os.difftime( os.time(), Cooldowns[player:GetName()] ) < 60*NUM_MINUTES ) then
pUnit:SendChatMessage(14, 0, "You have to wait "..( NUM_MINUTES - (os.difftime( os.time(), Cooldowns[player:GetName()] ) / 60)  ).." more minutes to play a song again.")
return;
end

Cooldowns[player:GetName()] = os.time();

if (intid == 1) then
pUnit:SendChatMessage(14, 0, "Rock this party DANCE everybody!")
pUnit:PlaySoundToSet(11803)
pUnit:GossipComplete(player)
end

if (intid == 2) then
pUnit:SendChatMessage(12, 0, "Make it HOT! in this club.....")
pUnit:PlaySoundToSet(11699)
pUnit:GossipComplete(player)
end

if (intid == 3) then
pUnit:PlaySoundToSet(11704)
pUnit:GossipComplete(player)
end

if (intid == 4) then
pUnit:SendChatMessage(12, 0, "Dont STOP move your body!")
pUnit:PlaySoundToSet(11802)
pUnit:GossipComplete(player)
end

if (intid == 5) then
pUnit:SendChatMessage(14, 0, "Everybody DANCE now!")
pUnit:PlaySoundToSet(11466)
pUnit:GossipComplete(player)
end
end

i love u! +REP

[Pieterkii]

this coding is for every1 who wants to choose a song rite?...i dont want permanent music on the server...so if i choose a song at 2:00, u/ me will be able to choose 1 at 5:00 again rite?

[Jotox]

yes.

The way it works is every time a player chooses a song, it records an entry in the "Cooldowns" table. The entry has the player's name and the exact second that he chose the song.

Then, when a player tries to choose another song, it searches for an entry in the table that has the player's name.

If an entry with the player's name is found, and the time associated with the entry is less than 3 hours ago, the player can't play another song.

[Pieterkii]

does that mean that No'one will be able to use it in the next 3 hours??? i hope so...cause thats what i wanted..otherwise other people would come and it would be a constant noise 0.0

[Jotox]

Oh, no... I did it on a player by player basis

No one using it for 3 hours is much simpler >_<...

local Cooldown = 0;
NUM_MINUTES = 60*1;	--1 hour <----PIETERKII, EDIT TO CHANGE THE COOLDOWN

function Music_OnGossipTalk(pUnit, event, player, pMisc)
pUnit:GossipCreateMenu(100, player, 1)
if ( os.difftime( os.time(), Cooldown ) < 60*NUM_MINUTES ) then
pUnit:GossipMenuAddItem(0, "This is still on cooldown. You have to wait"..( NUM_MINUTES - (os.difftime( os.time(), Cooldown) / 60)  ).." more minutes to play a song again.", 99, 0)
else
pUnit:GossipMenuAddItem(0, "*Rock*", 1, 0)
pUnit:GossipMenuAddItem(0, "*holy life -srinty bpeers*", 2, 0)
pUnit:GossipMenuAddItem(0, "*Drums*", 3, 0)
pUnit:GossipMenuAddItem(0, "*MURLOC*", 4, 0)
pUnit:GossipMenuAddItem(0, "Wooot? Illidan??", 5, 0)
end
pUnit:GossipSendMenu(player)
end


function Music_OnGossipSelect(pUnit, event, player, id, intid, code, pMisc)

if intid==99 then
pUnit:GossipComplete(player);
return;
end

if ( os.difftime( os.time(), Cooldown ) < 60*NUM_MINUTES ) then
pUnit:SendChatMessage(14, 0, "You have to wait "..( NUM_MINUTES - (os.difftime( os.time(), Cooldown) / 60)  ).." more minutes to play a song again.")
return;
end

Cooldown = os.time();

if (intid == 1) then
pUnit:SendChatMessage(14, 0, "Rock this party DANCE everybody!")
pUnit:PlaySoundToSet(11803)
pUnit:GossipComplete(player)
end

if (intid == 2) then
pUnit:SendChatMessage(12, 0, "Make it HOT! in this club.....")

There's the code. I changed it to 1 hour, since... well, imo, 3 hours is a bit much for songs that last 3 minutes at most :P

Ty you are my star!
