[Question]Limiting packets in a certain place

[Kardil]

As i said i want to prevent some packets from a certain region
for example:
i wanna prevent players using return scroll from a region .. i knew that is using a packet filter ( as i understood ) but i don't have a source for a packet filter or even know how it works.

thanks in advance

There are multiple sources for packet filters lying around in the forum. You need to take a good look at them.
The concept is pretty straight forward: you'll monitor the player's movements through packets and save the regionID in a variable, then you need to find and parse the packet that is concerned with using inventory items and get to know the return scroll type. Intercept that packet and put a conditional IF statement as the following pseudo code:

if packet opcode == inventory using item
{
if parsed type == return scroll usage
{
if this client's regionID == prohibited regionID
//do whatever you want, either ignore the packet or send an error msg
}
}

thanks that's so useful .. but if you don't mind lead me with a link or something to a good & trusted filter as i searched for it but no thing.

Check the releases section. I never used any of the released ones, so I can't really tell.

You'll have to go through a lot of shiz to get a one working well, If u want to ignore the packets if X packet was sent, just use "continue;"

I released a old source, but okay.
Then do it on your own
