Selecting Npc - Opening window and buying items

[sarkoplata]

Hello guys,
As you can understand , i am working on loop. All my code is ready for town loop to buy potions etc. with required amount but i have problems with npc's.

Items should be bought while only npc is selected. But something is wrong , my client is keeps getting crashed.

To select Jewelery NPC :

Dim Jewel As New Packet(&H7045)
        Jewel.WriteUInt32(73)
        Proxy.ag_remote_context.Security.Send(Jewel)

To buy item from NPC :

    Dim BuyDrugs As New Packet(&H7034)
        BuyDrugs.WriteUInt8(8)
        BuyDrugs.WriteUInt8(2)
        BuyDrugs.WriteUInt8(0)
        BuyDrugs.WriteUInt16(1)
        BuyDrugs.WriteUInt32(73)
        Proxy.ag_remote_context.Security.Send(BuyDrugs)

Im seaching for the reason of crash but
Btw: when i login after crash, item is in my inventory
Thanks in advance

as I remember
some1 made thread here (maybe jremy dun remember)
he had the same problem but with buying item from stall network
he had to block a packet which causes crashes


Edit: here you can get your answer

Thank you ! jremy had same problem with me , but i couldnt really understand what packet to block.

In that other thread Shadowz75 already explained your problem.

The client isn't prepared for a buy packet from the server so it crashes. You have to filter this packet out so the client doesn't get it and you have to send a pickup packet to the client to simulate that it picks up an item. This way you can see the bought item in the inventory and the client doesn't crash.

To kevin :

Ok well , i blocked the packet when server sends when i buy item from npc. And so i didnt crash but i wasnt able to see the item in my inventory , of course.

So to see the item i did (faked pickup packet)

Dim FakeSuccess As New Packet(&HB074)
                            FakeSuccess.WriteUInt8(1)
                            FakeSuccess.WriteUInt8(1)
                            Proxy.ag_local_context.Security.Send(FakeSuccess)

Dim FakePickUp As New Packet(&HB034)
                            FakePickUp.WriteUInt8(1)
                            FakePickUp.WriteUInt8(6)
                            FakePickUp.WriteUInt8(Slot)
                            FakePickUp.WriteUInt32(ItemId)
                            FakePickUp.WriteUInt8(Amount)
                            Proxy.ag_local_context.Security.Send(FakePickUp)

Dim FakeOK As New Packet(&HB074)
                            FakeOK.WriteUInt8(2)
                            FakeOK.WriteUInt8(0)
                            Proxy.ag_local_context.Security.Send(FakeOK)

Although i was sure that would not work , i just tried. And it made my client crash.So should i send the pickpacket also ? well , since it does not have any uniqueid as a drop...

seriously,would you stop asking EVERYTHING related to your "bot"?..
if you can't solve them alone,or using google,then stop it..
it's OK if you ask some questions,but I see your questions daily,so basicly you want epvp community to make a bot for you?..

well,that one was answered already,in 2 threads if I remember well,& about the other crash,you send the wrong packets..just block the incoming buy potion packet,and replace it with an other one.there's no need for 0x7074 and dunno the other one

but you really should look up things yourself..

as far as i remember it is possible to buy from npc without blocking any packet.
i did it some time ago and it worked fine (ecsro)
i can test it later on esro (guess you're trying to use it there)

i used to do it at swsro but its not working here.

You have to "emulate" talking to NPCs via packets because of the way the client is setup. This has been the case in Silkroad since the beginning. It's why isrobot used to get stuck on shop menus back around version 1.0XX (Softmod days), they had some client interactions, but it was dependent on resolution and window focus. So you do need to block some packets, and then send others to the client to update the inventory. Otherwise, your inventory can get out of sync and you have to teleport to fix it.
