[Question] About Lua

[Nilrac]

I have had this idea for a server, but I need to know if something is possible.

First, it is possible to script a door or gate to open at a certain server time using C++ or Lua?

Also is it possible to add your own music into the server and play it in a script with Unit:PlaySoundToSet(SoundID)

[Maven01]

The Door or Gate would have to probably be C++...I've looked in the Lua functions (Both Lua++ and ArcEmu's...) and found nothing.

int luaGameObject_GetName(lua_State * L, GameObject * ptr);
int luaGameObject_GetMapId(lua_State * L, GameObject * ptr);
int luaGameObject_GetCreatureNearestCoords(lua_State * L, GameObject * ptr);
int luaGameObject_GetGameObjectNearestCoords(lua_State *L, GameObject * ptr);
//int luaGameObject_GetAreaID(lua_State * L, GameObject * ptr);
int luaGameObject_GetClosestPlayer(lua_State * L, GameObject * ptr);
int luaGameObject_GetZoneId(lua_State *L, GameObject * ptr);
int luaGameObject_GetItemCount(lua_State * L, GameObject * ptr);
int luaGameObject_GetSpawnX(lua_State * L, GameObject * ptr);
int luaGameObject_GetSpawnY(lua_State * L, GameObject * ptr);
int luaGameObject_GetSpawnZ(lua_State * L, GameObject * ptr);
int luaGameObject_GetSpawnO(lua_State * L, GameObject * ptr);
int luaGameObject_GetInRangePlayersCount(lua_State * L, GameObject * ptr);
int luaGameObject_GetEntry(lua_State * L, GameObject * ptr);
int luaGameObject_GetX(lua_State * L, GameObject * ptr);
int luaGameObject_GetY(lua_State * L, GameObject * ptr);
int luaGameObject_GetZ(lua_State * L, GameObject * ptr);
int luaGameObject_GetO(lua_State * L, GameObject * ptr);
int luaGameObject_GetInRangePlayers(lua_State * L, GameObject * ptr);
int luaGameObject_GetInRangeGameObjects(lua_State * L, GameObject * ptr);
int luaGameObject_GetInstanceID(lua_State * L, GameObject * ptr);
int luaGameObject_GetUInt64Value(lua_State * L, GameObject * ptr);
int luaGameObject_GetUInt32Value(lua_State * L, GameObject * ptr);
int luaGameObject_GetFloatValue(lua_State * L, GameObject * ptr);
int luaGameObject_GetGUID(lua_State * L, GameObject* ptr);
int luaGameObject_Teleport(lua_State * L, GameObject * ptr);
int luaGameObject_AddItem(lua_State * L, GameObject * ptr);
int luaGameObject_Despawn(lua_State * L, GameObject * ptr);
int luaGameObject_IsInWorld(lua_State * L, GameObject * ptr);
int luaGameObject_IsInBack(lua_State * L, GameObject * ptr);
int luaGameObject_IsInFront(lua_State * L, GameObject * ptr);
int luaGameObject_PlaySoundToSet(lua_State * L, GameObject * ptr);
int luaGameObject_SpawnCreature(lua_State * L, GameObject * ptr);
int luaGameObject_SpawnGameObject(lua_State * L, GameObject * ptr);
int luaGameObject_CalcDistance(lua_State * L, GameObject * ptr);
int luaGameObject_SetOrientation(lua_State * L, GameObject * ptr);
int luaGameObject_RemoveFromWorld(lua_State * L, GameObject * ptr);
int luaGameObject_CalcRadAngle(lua_State * L, GameObject * ptr);
int luaGameObject_SetUInt32Value(lua_State * L, GameObject * ptr);
int luaGameObject_SetUInt64Value(lua_State * L, GameObject * ptr);
int luaGameObject_SetFloatValue(lua_State * L, GameObject * ptr);
int luaGameObject_ModUInt32Value(lua_State * L, GameObject * ptr);
int luaGameObject_CastSpell(lua_State * L, GameObject * ptr);
int luaGameObject_FullCastSpell(lua_State * L, GameObject * ptr);
int luaGameObject_CastSpellOnTarget(lua_State * L, GameObject * ptr);
int luaGameObject_FullCastSpellOnTarget(lua_State * L, GameObject * ptr);
int luaGameObject_EventCastSpell(lua_State * L, GameObject * ptr);

that's all the Lua++ Gameobject functions.

and the Music is more on the client instead of the server. So you would need MyWarcraftStudio (to add music...) and to edit the MPQ's/DBC's for the Sound ID to be added.


Hope this helped in anyway.

I'd say it is possible with LuA, but you cannot trigger the same door to literally open at a certain time, You would have to write a script to despawn the game object and spawn it back in Opened, so I'm not talking about a REAL door that opens and closes, you would have to just use two basic doors that dont open and spawn them back at an angle that appears as if they opened.

Thats your best bet with LuA

As far as playing music, you cant play music to other players unless they have the music on their client as well, this requires a patch..havent seen it done in a long long time.

Alright, thanks guys

Tbh.. If you use a working gameobject the door thing is simple.. ill give u an example inasec.

The only way to add music to your server is to get the sound files into the other players client. Ex, by using an mpq.

function Door(GameObject)
OpenDoor=GameObject
end

RegisterGameObjectEvent(gameobject entry id here,1,"Door")

function Dooropen (Unit, Event)
Unit:RegisterEvent("Dooropen_Open", Time, 0)
end

function Dooropen_Open(pUnit)
        OpenDoor:ActivateGameObject()
end

Argh the edit feature is messing up.. combine the 2 code boxes in one and u got the script

[Nilrac]

Thank you +rep

Np hon

[TheSpidey]

Exposing the server time to Lua doesn't sound that hard at all, nor does exposing TimedEvents to it.
I'll see if I can implement those two things.

[runiker]

I will plus rep the person who shows me the code to get server time as i need ti as well thank you!

[TheSpidey]

You can use os.date for this.

if os.date("%H:%M") == "21:00" then
<do something>
end
