I need help with adding a button to the main menu

[JonasunderscoreJones]

I'm trying to put a button on the title screen but i get an error message back claiming that the string can't be converted to text (the text I'm trying to display inside the button):

C:\Users\Jones\Desktop\mystery-mod-1.17.1\src\main\java\net\mystery\mod\mixin\TitleScreenMixin.java:23: error: incompatible types: String cannot be converted to Text this.addButton(new ButtonWidget(this.width / 2 - 100 + 205, y, 50, 20, "bruh", (buttonWidget) -> {
This is my code:

package net.mystery.mod.mixin;

import net.minecraft.client.MinecraftClient;
import net.minecraft.client.gui.screen.Screen;
import net.minecraft.client.gui.screen.TitleScreen;
import net.minecraft.client.gui.screen.world.SelectWorldScreen;
import net.minecraft.client.gui.widget.ButtonWidget;
import net.minecraft.text.Text;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfo;

@Mixin(TitleScreen.class)
public abstract class TitleScreenMixin extends Screen {

    protected TitleScreenMixin(Text title) {
        super(title);
    }

    @Inject(at = @At("RETURN"), method = "initWidgetsNormal")
    private void addCustomButton(int y, int spacingY, CallbackInfo ci) {
        this.addButton(new ButtonWidget(this.width / 2 - 100 + 205, y, 50, 20, "bruh", (buttonWidget) -> {
            MinecraftClient.getInstance().openScreen(new SelectWorldScreen(this));
        }));
    }
}

I used this tutorial and I my code looks exactly the same (apart from the value of the string) but it doesn't work for me. Please help!

You need to use a Minecraft Text instead of a string (the tutorial is likely outdated in this case). A text can be one of

• TranslatableText (the preferred type of text since it works with multiple languages), which takes a translation key in a lang file
• LiteralText, which is just your string wrapped in a Text instance

(there are other types of Text too, but those are mostly irrelevant here).

Also, you can use Fabric API (fabric-screen-api-v1 to be specific) to add buttons to screens without mixins. See the ScreenEvents javadoc for an example.

It works now, thanks! I just used LiteralText but once the mod is complete I will probably change it to TranslatebleText. I will have a look into the fabric screen api but I think for the moment it might be a little to advanced for me as I have just startet modding and my java knowledge is very limited too

Just as a side-note: TranslatableText accepts any string as input, not just translation keys

[JFronny]

TranslatableText only accepts translation keys. If no translation is found, it will fall back to displaying the key. You can, of course, abuse this behavior by using the string you wish to be displayed as a translation key without a translation, but LiteralText is the correct class to use for that

Do this:

package pack1.pack2.pack3;

import net.minecraft.client.gui.screen.Screen;
import net.minecraft.client.gui.screen.TitleScreen;
import net.minecraft.client.gui.screen.world.SelectWorldScreen;
import net.minecraft.client.gui.widget.ButtonWidget;
import net.minecraft.text.Text;
import org.spongepowered.asm.mixin.Mixin;
import org.spongepowered.asm.mixin.injection.At;
import org.spongepowered.asm.mixin.injection.Inject;
import org.spongepowered.asm.mixin.injection.callback.CallbackInfoReturnable;

@Mixin(TitleScreen.class)
public class HomeScreen extends Screen {


    protected HomeScreen(Text title) {
        super(title);
    }

    @Inject(at = @At("RETURN"), method = "addNormalWidgets")
    private void addModsButton(int y, int spacingY, CallbackInfoReturnable<Integer> cir) {
        this.addDrawableChild(ButtonWidget.builder(Text.translatable("modname.customButton"), (button) -> {
            this.client.setScreen(new SelectWorldScreen(this));
        }).dimensions(this.width / 2 - 200 +252, y, 50, 200).build());
    }
}

Inside of your resources folder (there where you have assets, the mixin file and the fabric.mod.json file) add the file: ./assets/modname/lang/en_US.json
the content of the file:

{
    "modname.customButton": "ButtonText"
}

When adding a custom button in Minecraft 1.21.11 (Not sure if this works on upper versions) I found the following to work:

Inject at createNormalMenuOptions
render via addRenderableWidget using Button.builder(...)
Any text rendered in Minecraft is done here uses Component.translatable(String)
Then render your object via setScreen
On my part, dimensions was not found but .bounds was a viable solution for me!

Perhaps anyone working on 1.21.11 will find this useful!

You do not need a mixin to do this, you can use the ScreenEvents.AFTER_INIT event, see:

Ahhh! Much appreciated.
