Consistent GUIDs

[Iorveth]

I've been messing around with writing an addon in the MoP beta and using some functions that involve NPC GUIDs and was wondering if any of these will be the same in the actual release of the game.

So as not to completely waste the hours and hours I'd potentially be spending on development, how consistent do you all think GUIDs will remain between the MoP beta and the MoP live?

yes. I know what a GUID is; sorry. I meant to ask how likely it is that the NPC IDs will change when the client goes live.

e.g. the NPC "Ken-Ken" (in my instance of mop) has a GUID of 0xF53000DB33071003; will it be 0xF53000DB33------ at launch or will it be assigned a new NPC id (something like 0xF53000D13B------)?

I realize nothing is set in stone, but are there any trends as far as IDs carrying over from beta clients or PTR clients?

Sorry for being ambiguous, by the way.

Easy way to check would be to login to different live servers, target the same NPC and /print UnitGUID("target")

I believe the NPC ID should not change, but obviously the rest of the GUID will. Easy way to verify would be to go to an NPC that exists in live and beta and compare.

AFAIK different servers have different object GUIDs.

Yeah, the GUID will be different, was mainly referencing the NPC ID in the GUID:

He referenced:
0xF53000DB33071003

DB33 = 56115:
Ken-Ken - NPC - World of Warcraft

That shouldn't change

Use NPC Name instead of GUID for reference.

Use NPC Name instead of GUID for reference.

But you know that names are not unique, but Ids are?
