i get this error not only with startWaterTask i get and with others, and same error 14000 lines... one time per day.

 

Maybe anyone know how to solve this problem?

The stackoverflow is a bug plaguing any aCis since at least 2y, it has been fixed with revert of movement system back to L2J.

[Tryskell]

Just a little addapt and is ok :D

[wongerlt]

Little? I'm many things changed in server core , so move all changes is hard :D

Thats why people use svn :D you can save your work even with a patch

[SweeTs]

Still progress is not lost. Take clean pack, the same revision, create SVN, replace with your actual sources and boom, you have diff patch with all your changes :)

[wongerlt]

Im use only notepad++ and ant (to compile). Im try to use eclipse but its very uncomfortable for me :/

And i see on latest version many changes, so i need rework all me codes to adapt ;)

Will be a lot of work from ~300 to ~360 :D

[wongerlt]

Oh why on latest version material, crystal_type, weapon_type are upercase? :D

[SweeTs]

Because they are not lowercase, obviously. It's an enum.

[Tryskell]

I force enum whenever I can.

[wongerlt]

To much work to move all server to new aCis version... Maybe anyone can tell me more about this movement system bug. Thanks :)

Example about bug that need target self to can move at start, but not all time.

You need to find the recursive call... ^^

You mean when function call self or call other function who call 1# function and it make while?
