Game objects

[Xmaily]

Hey guys i'm working on scripting Ulduar currently and it's going pretty well however I would like to know how to activate a game object (example a door closing on combat and re opening on leave combat/ defeat)

I learn best when it's shown to me rather then told so if anyone can link a script they have made before or a script that uses the activate/ deactivate functions please link it!

You need to set the unsigned integer value (32), bytes, to activated (1) or deactivated (0).

I have no idea what that means could u show me a example from a script? What would i need to define at the start of it?

I don't know what emulator you are using or what, you could look at code examples from the currently scripted dungeons.

Here is a code snippet from the TrinityCore Black Temple script:

                instance->SetData(DATA_ILLIDANSTORMRAGEEVENT, NOT_STARTED);

                IllidanGUID = instance->GetData64(DATA_ILLIDANSTORMRAGE);
                GateGUID = instance->GetData64(DATA_GAMEOBJECT_ILLIDAN_GATE);
                DoorGUID[0] = instance->GetData64(DATA_GAMEOBJECT_ILLIDAN_DOOR_R);
                DoorGUID[1] = instance->GetData64(DATA_GAMEOBJECT_ILLIDAN_DOOR_L);

                if (JustCreated) // close all doors at create
                {
                    instance->HandleGameObject(GateGUID, false);

                    for (uint8 i = 0; i < 2; ++i)
                        instance->HandleGameObject(DoorGUID[i], false);
                }
                else // open all doors, raid wiped
                {
                    instance->HandleGameObject(GateGUID, true);
                    WalkCount = 1; // skip first wp

                    for (uint8 i = 0; i < 2; ++i)
                        instance->HandleGameObject(DoorGUID[i], true);
                }

Or in ArcEmu, this is the Lua approach I have used:

local OBJECT_END = 0x0006
local GAMEOBJECT_BYTES_1 = OBJECT_END + 0x000B

...

local gate = pUnit:GetGameObjectNearestCoords(x, y, z, gameObjectId)
if gate then
  gate:SetByte(GAMEOBJECT_BYTES_1,0,0) -- open door
  gate:SetByte(GAMEOBJECT_BYTES_1,0,1) -- close door
end

The C++ code is pretty much the same.

Thanks so much harry it worked! I only have one more question how to i make it non selectable?

You need to set UNIT_FIELD_FLAGS to UNIT_FLAG_NOT_SELECTABLE.

local OBJECT_END = 0x0006
local UNIT_FIELD_FLAGS = OBJECT_END + 0x0035
local UNIT_FLAG_NOT_SELECTABLE = 0x02000000 -- this is the same as going in game and doing .mod flag 33554432

...

pUnit:SetUInt32Value(UNIT_FIELD_FLAGS, UNIT_FLAG_NOT_SELECTABLE) -- unselectable

...

thanks ^-^

So i have been using opening and closing game objects like mad! But today i tired to make one unslectable from ur post above. However i'm confused. If my game object has been spawning already without a script where would i put pUnit:SetUInt32Value(UNIT_FIELD_FLAGS, UNIT_FLAG_NOT_SELECTABLE). Would i be like this...

local gate = Ruag:GetGameObjectNearestCoords(-10461, -3219, 20, 215223)
if gate then
gate:SetByte(GAMEOBJECT_BYTES_1,0,0) :SetUInt32Value(UNIT_FIELD_FLAGS, UNIT_FLAG_NOT_SELECTABLE)

Note it says "UNIT_FIELD_FLAGS". Units are creatures or players.

GameObjects have their own set of flags. ID 1 is untargetable in the database, need to look up how to do it in code but you can look in the documentation just as well as I can.

I know this is a stupid question but how what would i look for in the database i have no clue!

They are defined in the emulator.

GAMEOBJECT_DISPLAYID =                     OBJECT_END + 0x0002 -- Size: 1, Type: INT, Flags: PUBLIC
GAMEOBJECT_FLAGS =                         OBJECT_END + 0x0003 -- Size: 1, Type: INT, Flags: PUBLIC
GAMEOBJECT_PARENTROTATION =                OBJECT_END + 0x0004 -- Size: 4, Type: FLOAT, Flags: PUBLIC
GAMEOBJECT_DYNAMIC =                       OBJECT_END + 0x0008 -- Size: 1, Type: TWO_SHORT, Flags: DYNAMIC
GAMEOBJECT_FACTION =                       OBJECT_END + 0x0009 -- Size: 1, Type: INT, Flags: PUBLIC
GAMEOBJECT_LEVEL =                         OBJECT_END + 0x000A -- Size: 1, Type: INT, Flags: PUBLIC
GAMEOBJECT_BYTES_1 =                       OBJECT_END + 0x000B -- Size: 1, Type: BYTES, Flags: PUBLIC
GAMEOBJECT_END =                           OBJECT_END + 0x000C

So if you try setting GAMEOBJECT_FLAGS to the value 1, it might work:

gate:SetUInt32Value(GAMEOBJECT_FLAGS, 1)

Remember to define OBJECT_END, GAMEOBJECT_END and GAMEOBJECT_FLAGS.

I' dont mean to be a bother. I just simply understand it better like that ^-^ the way u but it in last post doesn't make much scene to me >.<
