Using Crying Damson 0.3.5pl1

Thanks.

@EDIT: I have OTAL Installed.

@snacky
you got attack or you connection got down!
well i wiil check about this error, in normal cases it dont print error ._.'

 

[snacky]

Well, i guess that my connection went down when this occur, because, currently i dont get im beign attacked, im changing my IP frequently, becuase im working with DNS's and stuff.


But, what could be the problem? it isnt strange? Thank you.

 

[snacky]

ive tried to run the script to test accuracy, and i opened the server, logged in from local computer, and unplugget internet cable.

After like 12 seconds, the script shows

[22/10/2009 03:26:53] [Error - GlobalEvents::think] Couldn't execute event: ddos

But it didnt even kicked me, or saved the server, also i make sure didnt disabled anything on the noDDoS.lua file


thanks

@snacky

, logged in from local computer, and unplugget internet cable.

This it the cause ._.''''''''
i will rewrite script.

 

[snacky]

Oh, but that works if i really lost connection? well unplugin the cable its connection lost already..

It works?

 

[Mock]

@snacky
Bug fixed

yes if you unplug internet cable, or go to offline mode or something like
this script will kick all players

 

[snacky]

Buddy, it does kick the players, but didnt save the server and close it.

Any ideas?

Thanks you. (i just unplugged the cable)

Any function to do this?
