I'm making currently a Command that shows you Information of the World. There you can also see the Seed of the World.

But I want it to make it clickable to make it copyable to clipboard.

Know someone what the Code is?

Add a MutableComponent with a Style that sets the clickEvent when action of COPY_TO_CLIPBOARD.

Thank you!

One Question:

What is the best Method to implement MutableComponent inside of displayClientMessage Method?

Here is a Code and tried to implement it inside it:
 

if (entity instanceof Player _player && !_player.level.isClientSide())
			_player.displayClientMessage(new TextComponent(("§6" + "Seed: " + "§r" new MutableComponent(world.getServer().overworld().getSeed()).withStyle(style -> style.bold(true)).build())), (false));

 

But got this Error:
error: MutableComponent is abstract; cannot be instantiated

There is already is a command that does what you want.

See SeedCommand

No what I want is how to use MutableComponent correctly inside of displayClientMessage.

No. You should do your own research. We are not going to write your mod for you.

 

In this case, look at how Mojang creates theirs in SeedCommand.

If you did this, you spent less than 20 minutes trying to figure it out for yourself.

hint: (Mutable)Component is an interface so you are looking for one of its concrete subclasses.

 

I got to made the Component that I copied from SeedCommand to work.

But the only issue that if I get the Component Variable inside the displayClientMessage and using getString() it only prints the String but not the Style to the chat.

I think I'm missing something...

Component TestComponent = ComponentUtils.wrapInSquareBrackets((new TextComponent(TestString)).withStyle((TestStyle) -> {
			return TestStyle.withColor(ChatFormatting.RED).withInsertion(TestString);
		}));
		if (entity instanceof Player _player && !_player.level.isClientSide())
			_player.displayClientMessage(new TextComponent(TestComponent.getString()), (false));

 

Why are calling toString() on your Component and then wrapping that in another Component?

A java.lang.String is just an array of unicode characters. It has no way to understand or store Minecraft's style attachments.

Well that makes sense.

I need to mention that I never had to do with Component and ComponentUtils. Only with TextComponent and TranslatebleComponent.

So then I thought I can research for myself how to implement Text with Styles.
