snowstep115

Thank you. I understand that code. I should not use SimpleChannel.registerMessage.

Just not to call simpleChannel simultaneously.

In order to separate simpleChannel call and others. Other two mods have same initialization codes, they also set up channels by FMLCommonSetupEvent. I want to make other two mods stop setting up their channels during the one mod is setting up the channel.

Umm, here is main mod class. And event handler class.

You know I'm afraid that ChannelBuilder.simpleChannel, or more deep method, is not threadsafe. Actually, the exception has never caused by this way. Yes, I know this is stupid.

Although I really want to have something like an inter-mod mutex, I used stupidly temporary directory instead. It works well if only my initialization codes run. public static void init() { File file = new File("config" + File.separator + "snowstep115"); while (file.exists() || !file.mkdir()) { try { Thread.sleep(10); } catch (InterruptedException exception) { } } try { HANDLER = NetworkRegistry.ChannelBuilder.named(NAME) .clientAcceptedVersions(PROTOCOL_VERSION::equals) .serverAcceptedVersions(PROTOCOL_VERSION::equals) .networkProtocolVersion(() -> PROTOCOL_VERSION) .simpleChannel(); } finally { file.delete(); } }

I made three mods which have same initialization code for simple channel, and they run simultaneously. I've just made them create a same temporary directory during ChannelBuilder.simpleChannel in order to avoid this problem. It seems to work well now.

FMLServerStartingEvent has getCommandDispatcher method, and its return value has register method.

It works well. Thank you very much.

I have a problem to unable to set a property to IBlockState. Here is my code. public class BlockDock extends Block { public static final EnumProperty<EnumContainer> CONTAINER = EnumProperty.<EnumContainer>create("container", EnumContainer.class); public BlockDock(String name) { super(Properties.create(Material.IRON).hardnessAndResistance(1.5F, 1.0F).sound(SoundType.METAL)); setRegistryName(new ResourceLocation(ContainerMod.MODID, name)); setDefaultState(getDefaultState().with(CONTAINER, EnumContainer.EMPTY)); } } and error... Caused by: java.lang.IllegalArgumentException: Cannot set property EnumProperty{name=container, clazz=class com.snowstep115.container.util.EnumContainer, values=[EMPTY, QUEUE, STACK]} as it does not exist in Block{minecraft:air} at net.minecraft.state.AbstractStateHolder.func_206870_a(SourceFile:106) at com.snowstep115.container.block.BlockDock.<init>(BlockDock.java:36) at com.snowstep115.container.item.ItemDock.<init>(ItemDock.java:10) at com.snowstep115.container.ModItems.<clinit>(ModItems.java:11) ... 30 more Would you tell me the correct way to do it. Thank you.
