Duplicate post.


If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

If you mean the CreativeModeTabEvent.Register event, to register your own tab, you need to create a listener on the mod bus

@Mod.EventBusSubscriber(modid = "your_mod_id", bus = Mod.EventBusSubscriber.Bus.MOD)
public class CreativeTabEvents {
  public static void onRegisterCreativeTabs(final CreativeModeTabEvent.Register event) {

	event.registerCreativeModeTab(new ResourceLocation("your_mod_id", "tab_name"),
                builder -> builder
                        .icon(() -> new ItemStack(MyModItems.MyItem))
                        .title(Component.translatable("itemGroup." + "your_mod_id" + "." + name)) //you are not forced to this syntax, but it's pretty common

Assuming that MyModItems.MyItem is an item in a class of your mod that has all the items (of course you can set it to whatever item or block you want, even vanilla ones).

If, instead, you want to add items to your creative tab, you need to listen to the CreativeModeTabEvent.BuildContents event, in a similar way. In here you want to check which tab is being populated (event.getTab()) and, if is your tab, add as many item stacks as you want using event.acceptAll(itemStacks) method

  public static void onTabBuildContents(final CreativeModeTabEvent.BuildContents event) {
	final CreativeModeTab tab = event.getTab();
  	if(tab.equals(MY_CREATIVE_TAB)) {
      		new ItemStack(MyModItems.MyItem),
        	new ItemStack(MyModItems.MySecondItem)

Of course you need to have reference to your tab, so when you register it during the CreativeModeTabEvent.Register event make sure to store the registered tab into a variable so you can use it later on to add items to it.

You can see how I handle my tabs here to get an idea: https://github.com/JimiIT92/MineWorld/blob/master/src/main/java/org/mineworld/core/MWTabs.java

Don't blame me if i always ask for your help. I just want to learn to be better :)
