Hello, i got an issue registering my Screen Container.
I followed Jorrit Tybergheins Tutorial on creating a GUI. Again, everything works just fine but the GUI doesnt show up.

After checking the logs, i found the error:

[m[1;31m[21:24:18] [Server thread/FATAL] [minecraft/ThreadTaskExecutor]: Error executing task on Server

After hours of searching for a solution, i came to the point that it must be failing at the registration of my Container, but i cant get why it doesnt work.


Here is my Registry Class:

package com.kahmi.elementcrops.init;

import com.kahmi.elementcrops.ElementCrops;
import com.kahmi.elementcrops.objects.container.DungInfuserBlockContainer;

import net.minecraft.inventory.container.ContainerType;
import net.minecraft.util.math.BlockPos;
import net.minecraftforge.common.extensions.IForgeContainerType;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;
import net.minecraftforge.registries.ObjectHolder;

@Mod.EventBusSubscriber(modid = ElementCrops.MOD_ID, bus = Bus.MOD)
@ObjectHolder(ElementCrops.MOD_ID)
public class ContainerInitializer {
	@SubscribeEvent
	public static void registerContainer(final RegistryEvent.Register<ContainerType<?>> pEvent) {
		pEvent.getRegistry().register(IForgeContainerType.create((pWindowID, pInventory, pData) -> {
			BlockPos pos = pData.readBlockPos();
			return new DungInfuserBlockContainer(pWindowID, ElementCrops.PROXY.getClientWorld(), pos, pInventory, ElementCrops.PROXY.getClientPlayer());
		}).setRegistryName("dunginfuser"));
	}
}

if you need more code, i will setup github tomorrow.

Thanks in advance!

Show your TE class.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

This is null.

Well, that was unfortunate. in the tutorial video, it was actually null. i just shifted the IForgeContainerType.create method to the declaration section of my containertype, and now it works.
I Dont know why my GUI is rendering completely in grey, but thats another issue i might get handled myself.
Thanks.

Use a DeferredRegistry or @ObjectHolder annotations.

I have yet to look up how to use DeferredRegistry. For now, i will finish implementing the core mechanics of my mod and will then start to clean up things. I last modded like 1.7.10, so i have to refresh my knowledge, but thanks for pointing that out!
