Thanks for the advice! After some tweaking it seems like it was my pack.mcmeta , which had a json error (a comma in the last element of a list). The reason i did not include my gradle stuff in the repo is because theyre the default ones.

Yes https://github.com/MatCorgi/PrefixChat

When running my mod in eclipse it works fine but after i've builded it and put it in a normal minecraft instance it doesnt work [18:53:30] [main/FATAL] [FML]: There is a severe problem with prefixchat - it appears not to have constructed correctly [18:53:30] [main/ERROR] [FML]: Could not dispatch event: public void net.minecraftforge.fml.common.LoadController.propogateStateMessage(net.minecraftforge.fml.common.event.FMLEvent) to java.lang.NullPointerException [18:53:30] [main/FATAL] [FML]: Fatal errors were detected during PREINITIALIZATION.

Thanks! I tried that before but i was getting a error, probably because i didn't have the extends CommandBase part.

Is there any way to make it only run with the prefix? main package rf.mat.prefixchat; import net.minecraft.client.Minecraft; import net.minecraft.command.ICommand; import net.minecraft.init.Blocks; import net.minecraftforge.client.ClientCommandHandler; import net.minecraftforge.client.event.ClientChatEvent; import net.minecraftforge.common.MinecraftForge; import net.minecraftforge.fml.common.FMLCommonHandler; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.common.Mod.EventHandler; import net.minecraftforge.fml.common.event.FMLInitializationEvent; import net.minecraftforge.fml.common.event.FMLPreInitializationEvent; @Mod(modid = PrefixChat.MODID, name = PrefixChat.NAME, version = PrefixChat.VERSION) public class PrefixChat { public static final String MODID = "prefixchat"; public static final String NAME = "Chat prefix"; public static final String VERSION = "0.1"; private boolean hasPrefix; public PrefixChat() { this.hasPrefix = false; } @EventHandler public void preInit(FMLInitializationEvent event) { FMLCommonHandler.instance().bus().register(this); MinecraftForge.EVENT_BUS.register(this); ClientCommandHandler.instance.registerCommand(new testCMD()); } } command class package rf.mat.prefixchat; import net.minecraft.command.*; import net.minecraft.server.MinecraftServer; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.TextComponentString; import net.minecraftforge.client.IClientCommand; public class testCMD extends CommandBase { private void showMessage(final String message, final ICommandSender sender) { sender.sendMessage((ITextComponent)new TextComponentString(message)); } @Override public String getName() { return "test"; } @Override public String getUsage(ICommandSender sender) { return "test testing!"; } @Override public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException { // TODO showMessage("testing.",sender); } @Override public boolean checkPermission(MinecraftServer server, ICommandSender sender) { return true; } }

I would like to get every message the player types in the chat and "process" it to then send to chat later. How would i do such a thing?

I've been looking for the tellraw command class file in net.minecraft.command package and i cant seem to find it

When i try to compile my mod using gradlew build it fails the build and at the top it says: (use -source 8 or higher to enable lambda expressions) but then when i try to do gradlew build -source 8 it doesnt work
