How do i intercept/filter packets from client to server?

[Nanook]

I am working on a mod that requires me to intercept/filter some packets. How could i accomplish that?

What i need:

- When certain statement is true, deny some packets from going to the Server

What i thought about:

- ChannelPipelines (But dont really know if they could help me)

 

Thank you in advance

That example is bad, because you need to ensure your handler name is unique (they don't, "listener" is not unique...).

 

Also: you should really think long and hard about why you want to do this. You should describe what you want to achieve in terms of gameplay, not how you want to accomplish it in terms of coding. Usually you do not need to employ this hack.

i know its been a while but what happens if the handler name is not unique?
