[Help] Object interaction through script

[Imagine]

I had a quick look for any posts on the same subject but couldn't find any.

Currently im learning a little about scripting whilst working on the Halls of Reflection script, and iv hit a snag :

When you enter the instance, i want the first door to be closed (starts open) so i use this code :

from instance_hallsofreflection

void Initialize()
   {
       HandleGameObject(GUID_Door1, true);
    }

HandleGameObject contains :

void HandleGameObjects(uint64 GUID, bool activate, bool alternative = false)

//Copy of SwitchDoorOrButton from GameObject class

{

GameObject* pGo = instance->GetGameObject(GUID);

if(activate){

pGo->SetFlag(GAMEOBJECT_FLAGS, GO_FLAG_IN_USE);

}else {

pGo->RemoveFlag(GAMEOBJECT_FLAGS, GO_FLAG_IN_USE);

}

if(pGo->GetGoState() == GO_STATE_READY){ //if closed -> open

pGo->SetGoState(alternative ? GO_STATE_ACTIVE_ALTERNATIVE : GO_STATE_ACTIVE);

}else { //if open -> close

pGo->SetGoState(GO_STATE_READY);

}

}

Whenever this method is called (or more specifically when the line) :

pGo->SetFlag(GAMEOBJECT_FLAGS, GO_FLAG_IN_USE);

is called, mangos crashes with the error:

Debug Error

Run-Time Check Failure #2 - Stack around the variable 'szBuff' was corrupted

this happens when i use the above or DoUseDoorOrButton and SetGoState / SetLootState

can anyone divine the problem?

Yeah, usually the object hasn't actually been created when the instance script is initialized. You can set default state and flags in the database for this.

I hadn't thought of that, i assumed the world was populated before Initialize() was called,

anyway i moved that line to OnPlayerEnter and it seems to work now.

Thanks for the info

the OnObjectCreate() method should be more appropriated
