Against bots

[odisey]

already told... guru-boters cant sopped via this way. only lamers...
so if you need to kill all over bots - you need to hire assassins or

or just coding GS trafic by changes algorithm the formation of keys, but it needs client-side decoder.
When I finish my version of the such protector, maybe I will share the sources as an example ..

any combination with client-modding are forbidden here. about transistor for client via hosts or whatever(w/o modding) are in my post before

ok, sorry, my bad.

offtop: I will not use transistors, I'll take the thyristor mu-ha-ha-ha ( ).

Ok, what about invisible drop? Let's say you create item that each monster drops, but since you don't client modify anything, it's invisible/unpickable to player, but bots still should pick it up right?

As it was said before, that may be a great temporary solution, but bots could create a script to only pick up items that it knows what it is. I have made one of those before, not to get around this, but to keep a char's weight low (no I wont share it). Temporary, not permanent. Similar to the invis npc mobs.

I use that metod on my server. L2Net dev's already fix that. In latest version is option to not pickup items without mesh (texture ground) in client.

Nowadays it's like tilting at windmills... you know Don Quixote, don't you? You can stop the botters but only the inexperienced ones.

Ok, then how about this: some existing item (stem FOR EXAMPLE) is droped from each mob, but it's randomly visible to player or not, item id is the same, but if player picks up invisible one, then "IT'S ON" Or is it still possible with bot to detect if this item is visible to player or not. Or is it immposible to do such a thing?

once at 1 hour to appear a code on the screen and need to type it if not take kick

very disturbing for players and very inconvenient for them when taking a raid or other action. a "good" idea how to get rid of bots BUT also normal players.

[LasTravel]

On my opinion is better write one warning if player don't answer the anti bot request on console or on any other log than auto kick/ban/jail player.

If there is a way to make an item visible to the client or not, then the bot is going to have the same information. If a bot is perfectly coded, then there is no technical way to determine if the player is botting or not (since it does exactly what the client does). Only the 'gut feeling' of a good GM staff can determine whether someone is botting or not. But that method is not without its flaws. There is only one 100% accurate method of determining if the player is botting or not, and that is to be physically next to the player's computer looking at his/her screen. My opinion is a bit pessimistic, but it is the truth. There are some good, practical ways to determine if a player is botting, but the main problem with those is that once they reach the public svn here at L2J, then the bot creators (l2walker, l2net) can see what is broken and fix it.

First of all i'm newbie in developing and especialy in bots, don't use/test them. So if the points made below are nonsence just please answer normaly. I want to learn.

Talking about this part. What happens if we comment that line? Bot should not notice this change despite he's flawlesly codded.

[poltomb]

What that method (essentially) does, is puts the item in a list of objects that the character supposedly can see. This list is then periodically sent to the client (we call it updating the knownlist). If it is not put in that list, meaning you comment out that line, the client will not be able to see the item either.

[Other devs, please correct me if I am wrong]

[JIV]

still wil see it thx to

Code: Select all

_itm.getPosition().getWorldRegion().addVisibleObject(_itm);

changing that part - not a good idea
