Detect flag-capture in AB-style bgs

[Robske]

In an effort to make my life easier (and that of my bots more interesting) I've been searching for a way to detect when a (hostile) player is capturing a flag in a battleground - it's the 8 second cast I'm talking about, not the WSG style cap.

Now, only the client of the person capturing recieves the cast information. Other clients do not (and thus do not see a castbar on the person capturing) so reading the cast/channel info won't work.

The only visible information is:
- the swirling animation on the flag itself.
- the crafting animation on the player capturing.

Can anyone who has dealt with object animation shed some light on where this information is stored?

Edit: I'm currently detouring various animation functions coupled with trial and error to find a solution for this, just throwing it out here to both speed this process up and as an idea for the various pvp bot developers on this forum. Wand/Throw them cappers yeah!

I don't have WoW installed on this computer so I can't test this, but you could try checking if both UnitCastingInfo() = nil, and the object animation = crafting.

Hope this helps.

Thanks The Seadragon,

But I already got to that conclusion. In order to determine if a flag is being captured using only the 2 bits of information described above I need to check for players who do not have any casting/channeling info, have the crafting animation and being interact-distance from a flag that has the capturing animation. (additionally check if the flag/player relation allows interaction - horde players can't cap horde flags)

The object animation id for flags (gameobjects) will probably be the same offset as fishing bobbers, so no problem there.

I do not know where the animation data for players is stored.

It still needs to play a spell visual right?, i don't really remember its been a lonnnng time since i played a BG. If so it prob goes through
0x005D50A0 CGObject_C::PlaySpellVisualKit(PlaySpellVisualKitData const&)
at some point

Can't confirm nor test anything at the moment - at work. I haven't tried detouring this function just yet. The crafting animation I mentioned is the same when opening locked doors, chests, creating bandages... (without any glowing hands or cast bars).

Okay, well you could also try:
005A53B0 CGUnit_C::GetCurrentAnimation(void) const

EDIT: btw 00564040 CGPlayer_C::ToggleSheathe(void) is where i'm looking at these animation related functions

I do have access to IDA though CGUnit_C::GetCurrentAnimation looks very promising, thanks.

Edit: Great Success,

            var cappers = from player in Core.ObjectManager.Players
                          from flag in
                              from gameObject in Core.ObjectManager.GameObjects
                              where gameObject.Name.Contains("Flag") || gameObject.Name.Contains("Banner")
                              select gameObject
                          where !player.IsCasting && !player.IsChanneling
                            && player.CurrentAnimation == Animation.Crafting
                            && player.DistanceTo(flag) < 8
                          select new { Player = player, Flag = flag };

Animation.Crafting is 123.

I haven't researched this at any point, but have you checked for an aura?

For example:

Capture Point Flag Visual - Horde Controlled - Spell - World of Warcraft

Thanks The Seadragon

No problem.
