Thanks for the reply. I compared his current github code with my error and realized he must've updated the code. Seeing as his wikispaces died, I guessed that the jar he's providing for download isn't up to date with what's on the github. So I pulled the code and built it myself and it works just fine. For anyone who has this problem, just download his repo from github as zip, extract, then use gradle to build. The new jar will be in build/libs

Hi, I'm trying to get a server to run. It runs fine until I add the engineer's toolbox mod, and even fine if I remove the sockets from the mod. Normally I would just keep the mod out, but I'm not completely convinced the error is with the mod. Here's the crash report.

Hmm, I'll look into doing it that way. Thanks Looks like I might actually be able to use a PacketHandler to send the variables over and then just do rendering with them.

I realized that's not the best way to go now. I'm looking into some different ways to achieve what I'm looking for atm, possibly with tile entities. What I'm looking to do is to create a block that mimics others, but doesn't appear the same to everyone. The way it appears to someone will depend on a variable, such that perhaps player 1 has x = 4 and player 2 has x = 6, so player 1 sees the block as dirt while player 2 sees it as air. I've been trying to do this so many different ways, I appreciate all suggestions on ways to do it.

So I'm currently trying to dynamically update blocks via the server depending if the block is in a list or not. However, do note that I'm not using a custom block as it will not serve the purpose that I need and will cause too many side effects. Currently I do have the server changing block states in one second intervals, but the client doesn't update the blocks immediately. However, I feel there has to be an even better way, perhaps a way for the server to access all the blocks that the player is rendering? Essentially what I need, is a system that checks the blocks the player is seeing against a list, and if they're in that list then force the block to change on THAT PLAYER'S CLIENT ONLY. I don't every player to see the block changes, only that player. Think of it as observer dependency. So question 1: Is there a way to handle block observations for all blocks? And question 2: Is there a way to change blockstates only for a specific player? (Yes, I want to desynchronize player's block data with the server's block data) Thanks for any help and please ask if anything is unclear.

Alright, that helps a lot. Thanks! I should be able to get it working from here.

Ohh, alright thanks for that. That makes a lot more sense now. So the next question I suppose is when registering a handler with FMLCommonHandler, does that register it for both Client and Server? Should I register the handler in both ServerProxy and ClientProxy using FMLCommonHandler, but in ClientProxy, check if world.isRemote is true, and if so then don't register?

I'm writing a mod in 1.8 and I simply need to handle some server sided events. From my understanding, every game of minecraft, whether it be multiplayer or singleplayer, handles logic on server side (being dedicated server and internal server). I have a handler that detects block break and block places events, which I simply want to be handled by the server. I have this in my ServerProxy, however, when I run the code from eclipse, ServerProxy never initializes or registers as I see no output or recordings. The handler does work when on client side, but I need it on the server side. Thanks for any help!
