Help [BUG] Seven Signs Mobs

[Nevermind25]

Hello boys, i'm back with a rare bug in all catacomb/necropolis monsters that i can't solve.

Sometimes when someone hit a monster or a group of them or using Provoke or Agression/Group Hate the monsters stay in its place like without attack desire, them are there, static 

It happen to somebody? may be AI bug? Im using retail AI without modifications. 

 

This i've seen in many servers and without solutions, just restart L2NPC or L2Server. 

 

@MasterToma may be util for your project

I saw this also on retail PTS servers. Unfortunately, I'm far from C4 now, so can't help you here now.

It might be geodata or AI related. For AI you can try to add debug prints to check, if attack desire event comes

Do you use C4 PTS as a base? It's common problem on C4 original files, so maybe just a "some custom" won't be enough. 

 

Also, problem doesn't reproduce at 100%, according to my experience it's about 5% (so each 15-20 train), also - not at all catacombs. I saw it only in catacombs in near Giran harbor (40+ lvl if I remember correctly). 50+ lvl catacombs were good.

 

So, most probably it's a geo-data or path nodes issue. How geo-data can affect AI? L2NPC has logic:

1. Follow the target using path-finding

2. If path wasn't found, increment failure counter, and try again

3. If path-finding failed 10 times, then AI tries to do recovery and tries to teleport to the attacker or to the some random spawn point in his territory.

4. All this is quite complex, catacombs have multi-layered geo, with a lot of corners and walls, so when user does train, he goes into some corner, maybe there pathfinding stops working. Also, due to bug in geo, Mob can't teleport to user (he is in corner - no good places), so mob "hangs", and can't act.

 

@Nevermind25, could you provide more info? Do you see this bug only in some special catacombs, as I mentioned, or in all of them? Does it happen, when user goes into some corner, or when uses some complicated path to get the train?

Hello @MasterToma that bug is in all catacombs but not at the same time, as you say it is not reproduced 100% it happens after some time, may be after some trains. I think that must be the respawn of mobs because sometimes i kill all using //killnpc and when they spawn again are fixed , other way is restarting l2npc so:

 

1 - Not occurs in all cata/necro at the same time

2 - Spawning again may be fixed so i tell users to kill them one by one or if im in home just //killnpc

3 - When mob stuck he dont attack even when player goes at his side and hit, even with short range weapon(dagger, fist).

 

It's hard to try without a live server so many times you think that all is good but when users start his interaction in world some problems can be found :)

Sorry for necro-posting, but maybe it will help someone - problem is in weird bug in density map. Mobs think, there is no players near them, and them switch to sleep mode, so no reaction. To disable it - simply disable sleep mode in L2NPC.exe:
