Maybe a Fix for exploit when restart the server or shutdown

[EzEraL]

This code will paralyze all the players before the server restarts (15 seconds before the server restarts/shuts down by default but you can change it), and unparalyze them if the server restart is cancelled.

 

I create this because many ppl when server restarted or shutdown they cheat such us safe enchanting,buffs stucking and more

 

So the code is the following:

Thx for that

I dont understand the code... :S actually where to put it ...for example what is this? @@ -52,8 +52,35 @@

But in some servers you see a message that u cannot enchant while server restarts. Doesnt it work here?

[killer_007]

It freezes the playes and makes them invul (for the last 15''), while it announces them that, and stops their movement packs exchange with the server. It also has negate values if you wanna issue a stop shutdown command. It also forces you to issue at least a 60'' shutdown command...

 

I would say it is good, but, l2joff has added a security bar that does the same thing.. And i'm sure i had seen the same code arround... Gimme a sec ^^
