GetRelativePoint deg to rad

Would be better to take in radians than degrees for unit method GetRelativePoint
Dont forget to check gameobject method too.

ScriptMgr.cpp Changes from Trinity Source

TrinityCore/TrinityCore@8bcde41

•    virtual uint32 GetDialogStatus(Player* /*player*/, Creature* /*creature*/) { return 100; }
  

•    virtual uint32 GetDialogStatus(Player* /*player*/, Creature* /*creature*/) { return DIALOG_STATUS_SCRIPTED_NO_STATUS; }
  

and ...

•    virtual uint32 GetDialogStatus(Player* /*player*/, GameObject* /*go*/) { return 100; }
  

•    virtual uint32 GetDialogStatus(Player* /*player*/, GameObject* /*go*/) { return DIALOG_STATUS_SCRIPTED_NO_STATUS; }
  

It will compile still, but causes a client crash from mem access.

Command hook

Add command hook to mangos

See:
ElunaLuaEngine/ElunaTrinityWotlk@6cc6ba2
ElunaLuaEngine/ElunaTrinityWotlk@6324c8a

CastedCreatureOrGO method

Trinity replaced CastedCreatureOrGO method with KillCreditGO

commit # 7776016

On GossipHello Trigger

On GossipHello, for example item gossip hook, if you have a script triggered on the hearthstone you will keep casting this spell 8690, should not cast any spell.
Thank you

Config option

We could add a config option for enabling and disabling the engine.
Arc has has it too

ID of Npc_Taxi, Npc_special...

FIRST TO SAY: Sorry for my english, i try to do my best.

Hi, recently i compile this server. My first compile.

I use github, etc. so i got updated, and i see a "npc_tax.cpp" i supose is a Taxi NPC.

But cant see the ID to spawn.

Same happens with npc_special , npc_inkeeper , npc_proffesion

EquipItem() possible changes?

As discussed, possibly change method to not add item if player does not have the specific item in his inventory, maybe add bool argument? Ideas? Suggestions?

FindUnit

We should implement all for example map methods that you can use to get players and creatures by low guid on a map. and all similar methods.

Get in range units

Add a method to get all in range units

Remove lua_pushnil

Remove lua_pushnil from code and replace with Push.

Rewrite check

Move check rewrite changes from MaNGOS to TC
See:
https://github.com/eluna-dev-mangos/ElunaCoreWotlk/tree/RewriteCheck
https://github.com/eluna-dev-mangos/ElunaCoreWotlk/commit/3c606a75ea2c5975557a5c28ca0068bed8252004

Fixes arg reporting invalid index.
Also enhances error reporting and checks overall.

Change in LuaEngine.cpp load sequence

// break if we don't find dir
if (!hFile)
{
    TC_LOG_ERROR(LOG_FILTER_SERVER_LOADING, "Eluna::No `scripts` directory found!");
    return;
}

Instead of breaking, create directory and re-initialize engine, kgo!

Taxi methods

Need better documentation for taxi methods:

http://emudevs.com/showthread.php/851-LUA-C-Custom-Fly-Taxi-without-Gossip?p=6114#post6114

MountID is actually NPC entry.

PerformIngameSpawn no longer triggering

Updating local source with trinity after commit 1a5c0ad
seems to break PerformIngameSpawn. Haven't had a lot of time to go over trinity's recent commits to find out why, but I figured you all might want to know.

Mangos functions

Mangos functions that dont work on TC or need a solution.

Bug: Locals Gossip Menu Option

Hello. I'm having a small problem when merging Trinity and Eluna... Before the merge, My locals_gossip_menu_option works correctly. After, the menus still come up, but no longer do anything when you click on them for interaction. I have no errors or conflicts when merging.

Everything else seems working just fine... Just locals_gossip_menu_options not working after merging with Eluna.

Implement SetEquipmentSlots to Eluna

SetEquipmentSlots is used for Mr.Smite and others boss.
Expansion: Classic to WoTLK (atleast, I think cata and mop use it too, need to be confirmed tho)
http://www.trinitycore.net/db/dc8/structScriptedAI.html#a3576525c6a84c0110304496b935929eb

Possible implementation of SWIG and modular engine system

Possible implementation of SWIG and a completely modular script engine system. To be considered.

http://www.swig.org/

OnEquip not working

OnEquip hook is still not working properly.

Setting to change the script folder

Check that cmake doesnt autocreate scripts folder to release
Also fix that its created to the build folder, not automatically to release.

Creating a setting to change the script folder is now needed.

Suggestion: Eluna scripts directory config setup

Would be great if the scripts folder can be set from the config.

Example: Eluna.Scripts.Directory = "lua_scripts"

I will look tomorrow in the core so if I find out how I will do a pull request :)

Because I'm sure is something to edit around here :) https://github.com/ElunaLuaEngine/Eluna/blob/c6e9683c55061ff8bd1e5674b2d559fd1a55d421/TrinityCore/WotLK/src/LuaEngine/LuaEngine.cpp

CastCustomSpell

Implement CastCustomSpell method

Cmake folder and disable

Make cmake to create scripts folder and add cmake option to disable Eluna on compile. (also config option?)

GetExpansion methods/Enum library

https://github.com/ElunaLuaEngine/Eluna-TC-Cata/pull/1

The file has been removed, but the changes / the file should be added to:
https://github.com/ElunaLuaEngine/Scripts
Also possibly implement methods to get expansion as these definitions vary, so you can write cross exp scripts and or libraries like this

Item move methods

Add methods to move items around inventory.
Could also revisit other item methods the same time.

CreateGuardian

I hope this one could be implemented

pPlayer:CreateGuardian(entry, duration, angle)
pUnit:CreateGuardian(entry, duration, angle)

Reload eluna doesnt delete old events correctly

Old events stay when you use a reload command.
At least for players.
The problem does not occur in normal use as RemoveEvents works as intended and everything works fine after a restart too.

Just a bug with .reload eluna as well as with method to delete all events possibly

PushLong not handling negative correctly

PushLong doesnt handle negative values correctly.
-1 for example produces the same as uint32(-1) while it should produce -0x1

Problem with Building

Corbi's methods not added

https://github.com/Corbi/Source/commit/3e276724e1560c616d5e5a1614c1177f20df60a5
These methods were not added yet from Corbi's pull request.

DBC edit function

Change DBC editing function to directly edit the loaded DBC data on mangos and TC.
See mangos for an example.

Currently this is handled by loading the modified DBC to a map and inserting custom data to it then. (like spell DBC is handled)

[TC] Implement Creature::UpdateEntry

Can you implement this function?

https://github.com/TrinityCore/TrinityCore/blob/master/src/server/game/Entities/Creature/Creature.cpp#L357

Remove deprecate naming from engine

Remove deprecate "Nova" from i.e. line 38 LuaEngine.cpp etc.

LootHandler HandleLootOpcode issue

I found a issue at:

void WorldSession::HandleLootOpcode(WorldPacket& recvData)
{
    TC_LOG_DEBUG("network", "WORLD: CMSG_LOOT");

    uint64 guid;
    recvData >> guid;

    // Check possible cheat
    if (!_player->IsAlive())
        return;

    GetPlayer()->SendLoot(guid, LOOT_CORPSE);

    // interrupt cast
    if (GetPlayer()->IsNonMeleeSpellCasted(false))
        GetPlayer()->InterruptNonMeleeSpells(false);
}

---

"IsNonMeleeSpellCasted(false)" should be "IsNonMeleeSpellCast(false)"

GetHeight

Make the method global and make it return nil on invalid coords or if no height.

Perform ingame spawn

I have a problem with using PeformIngameSpawn.

function CreateNPC(EntryID, SpawnMap, SpawnX, SpawnY, SpawnZ, SpawnO)
    local ID = nil;

    for NPCID,NPCTable in pairs(NPC) do
        ID = NPCID;

        if(NPC[ID] == nil or not(NPC[ID]["IsCreated"])) then
            ID = ID - 1;
            break;
        end
    end

    if(ID == nil) then
        ID = 0;
    else
        ID = ID + 1;
    end

    NPC[ID] = {
        ["IsCreated"] = true,
        ["GameID"] = nil,

TC> Kreatyve [Human <Alliance>][Warrior][Level: 80] has connected.
NPC ID: 0 has failed to spawn.
Kreatyve [Human <Alliance>][Warrior][Level: 80] has disconnected.

Meybe you can look for the problem or provide an example. of how to use PerformIngameSpawn.

Crash on :RemoveItem()

Hey there,
I found an error (latest build) where the server will crash when you try to use player:RemoveItem() before the player got saved to the DB.

Hackfix in Lua atm:
player:SaveToDB()
player:RemoveItem()

ElunaGuard

Add ElunaGuard
See ElunaLuaEngine/ElunaTrinityWotlk@6cc6ba2

PLAYER_EVENT_ON_CHANNEL_CHAT

does not respond to the channels registered player.

Dont trigger GiveXP hook

Option not to trigger XP change hook for the player when using GiveXP method.
Otherwise results to infinite loop when using it on XP gaining events, which many seem to try.

Possible crash with taxi methods

Must check if on TC the same issue:
https://github.com/eluna-dev-mangos/ElunaCoreWotlk/issues/14

Fix TC wotlk travis

Fix travis build.
Travis has old stuff installed that doesnt match TC requirements.

Init AI

Reimplement AI initialization for creatures on TC on reload eluna.
Cant be done on mangos without a little stupid core modifications : |

Getting the area name as a string?

Hey, I don't see any method for retrieving the name of an area in a string format(eg. creature:GetAreaName()), there's only :GetAreaId().

Is there any workaround I can do to retrieve the name as a string?
