i found this function in COEP code....

 

{(INT64)L"ShowSellSeedList", 0x4c4630, 0x20fa650, 0x2, 0x2ebd7b0, 0x20fa648, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0},

 

maybe this lines has been some error???

You have no idea what your posting do you?

 

 

Check specificly where it crashed, and what function lead up to it.

Is it inside dll or l2server?

Threadlog gives good insight, but always check.

 

See if some of them would be suspectible to any form of overflow/crash situation.

 

 

Then you can determine wether its direct dll code, or some data passed from dll to l2npc makes it boomeloom.

and then make proper checks to ignore when it is.

L2server no errors...

[minideed]

Is this project still active? Last I checked it was dead a long time ago.

[mcbigmac]

Haven't had time to check the adress.

Will tonight.

 

 

As a big search area/parameter look thru any NPC <> L2Server information (Not sure there's that much in Open PP - if i remember correctly)

And look for loose/bad pointers and so on.

General memory no no's.

 

Link to the SVN of the one you use snoweagle, ill dll it and check.

 

 

Minideed:

It' still freely availeble with quite alot completed for a framework - if anyone wanted to continue.

Problem is the balls and brains to do so seem lacking :)

[minideed]

Would be nice if the project was started again. Looked good for a while and then it died out.

Would but would require someone to spool resources.

Testing is an integral part :)

 

But with the current situation it would also be lopsided, it'd be one of the few of us left pooling most work.

And then it's one short step to "if XYZ does most, why should all profit?(not in direct monetary sence, but overall)".
