Hello,

 

I am learning how to create mods using the MDK. I was able to configure the mod folder and import the project into Eclipse. If I run the program even without editing anything it crashes with the following message : 

[Render thread/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Failed to resolve handler for "net.minecraftforge.fml.network.simple.SimpleChannel$$Lambda$2232/0x000000080139e840@471d6571"

 

I am coding on Ubuntu. I have multiple jdk, with openjdk-8 as the default on.

The crash report  :

// But it works on my machine.

It's using Java 13 instead of the Java 8 installation you want it to. I don't use Eclipse, but this should tell you what to do to change it to Java 8.

I'm eager to learn and am prone to mistakes. Don't hesitate to tell me how I can improve.

      Also check the worldsave / serverconfig folder If there is no such file, make a test without this mod

      Forge Black Screen

      By Trimican · Posted

      Hi, I've been having trouble trying to use forge as it shows a black screen when I open the game, but I can still interact with it and hear the music.  I've done all of the step by steps and most common fixes like updating drivers, keeping up to date with Java, deleting and reinstalling minecraft, restarting my computer MANY times, even smaller things like splash.properties (I didn't have that file so I added it and set it to false thinking it would do something, definitely not) and making sure to prioritize my rtx 3070 in the settings but with no luck. Minecraft works as intended when I uninstall forge and I also don't have any mods currently, it just gives me this issue when I install forge. I also increased the ram usage, made sure my hardware isn't full or anything, and even changed the resolution in hopes it would fix things. I checked my antivirus and firewall but that isn't the issue either. Trust me, I've done everything I can think of. For some reason the black screen does flicker a little into the main menu, but obviously unplayable. I couldn't even make my way to the settings with how little it flickered. I'm not sure if it flickered randomly or if it was because I was messing around moving and clicking a bunch, I didn't really test it that much.

      Server doesn't boot (but without crashing somehow) whenever I add Deeper and Darker mod

      By K0wp3R · Posted

      I've had a really weird issue recently,  I wanted to add the Depper and Darker mod on my dedicated server (MC 1.21 with Fabric 0.16.9, hosted on nitroserv.com) but whenever I do add the mod the sever stops doing anything after listing the mods, and I get no crash or error or anything, just a stuck server. Here's a normal log of the server booting up: https://pastebin.com/JipFF2Eh and here's the log of the server doing the weird thing: https://pastebin.com/W4JBh3eX I just don't understand it. I've tried removing other mods (somewhat randomly) but deeper and darker still breaks my server whenever I add it. NitroServ support staff is about as confused as I am and I've had no response from the Deeper and Darker support staff... Now I know this is the Forge support not the Fabric support but I'm just trying to know if anyone has any kind of idea to fix this (aside from not using the mod obviously) Also I still have a bunch of errors and warnings whenever the server does start properly, are there any of them I should be worried about?
