Adding additional data to server status response JSON

[pauk960]

Hi. Is it possible to add additional data to server status response JSON? And if it is how would I do it?

1st things 1st - why? To do what exactly?

I want to create autoinstall, autoupdate script for my custom modpack (not on ftb). So, I was thinking of creating a small server mod that would add modpack version and modpack download URL fields to JSON status response. Script would then compare version, and download and install the modpack from provided URL.

Sending additional data (tho possible) will still require you to actually have client-reader.

Also - as mentioned - in-game updating is ridiculus. You would still have to restart the game.

 

What you can do:

* Make your own launcher or update-program (like forge installer).

* Download updates on startup (preInit of mod) and then force game-restart (I doubt forge will even allow you to realod classes in runtime, I've tried it and it's too messy).

* If update of modpack is server-dictated (server decides what client loads) you will still have to code some dynamic loading.

We use MultiMC, which has an option to define a pre-launch command that will be executed before launching Minecraft. So no, I wouldn't do updating from Minecraft client, but from script that runs before Minecraft. I've already created a script that send handshake to server and prints out response JSON in console.

 

If it's not possible to append data to response JSON, then my other solution would be to create a custom packet handler, and a script that mimics a Minecraft client.
