[1.11.2] Redirecting custom packets

[Dqckii]

Hey everyone, I'm trying to figure out how to intercept custom packets sent from the client to the server, while still in the client, and how to send a packet from the client to the same client making it look like it came from the server.

I have no idea how to this and any help would be greatly appriciated!

What is the context for this? What are you actually trying to achieve (in gameplay terms, not code terms)?

Make the MorePlayerModels mod  be usable on servers that don't have the plugin installed by intercepting and spoofing the packets the mod sends and receives.

That is the worst possible way to go about it. You should talk to the mod author to implement it properly instead of hacking around with packet spoofing.

I actually found a way to set the models for other players without packets already, I just need to find a way to get the player's current model, and I figured that would be the easiest if I intercepted the packet it sends to the server which includes it.

No, that is not a good way to do it. If the mod has an API: Use it. If it doesn't, bug the author to make one.

Fair enough, thanks!
