1.17.1 Text on UI

[e2rifia]

This is my code. How can I change it to have "Hello world!" show on the screen?

@Mod(Chants2.MODID)
public class Chants2 {
    public static final String MODID = "chants2";
    public Chants2(){
        final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
        final ClientSideOnlyModEventRegistrar clientSideOnlyModEventRegistrar = new ClientSideOnlyModEventRegistrar(modEventBus);
        registerCommonEvents(modEventBus);
        DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> clientSideOnlyModEventRegistrar::registerClientOnlyEvents);
    }
    public void registerCommonEvents(IEventBus eventBus) {
        //eventBus.register(GuiHandler.class);
    }
}

public class ClientSideOnlyModEventRegistrar {
    private final IEventBus eventBus;
    public ClientSideOnlyModEventRegistrar(IEventBus eventBus) {
        this.eventBus = eventBus;
    }
    public void registerClientOnlyEvents() {
        eventBus.register(GuiHandler.class);
    }
}

public class GuiHandler {
    String text = "Hello world!";
    @SubscribeEvent
    public void onRenderGui(RenderGameOverlayEvent.Post event)
    {
        drawString(event.getMatrixStack(), Minecraft.getInstance().font, text, event.getWindow().getWidth() / 2, event.getWindow().getHeight() / 2, Integer.parseInt("33AA66", 16));
    }
}

The text doesn't show. What did I do wrong this time?

public class GuiHandler {
    String text = "Hello world!";
    @SubscribeEvent
    public void onRenderGui(RenderGameOverlayEvent.Post event)
    {
        OverlayRegistry.registerOverlayTop("hello", new IIngameOverlay() {
            @Override
            public void render(ForgeIngameGui gui, PoseStack mStack, float partialTicks, int width, int height) {
                drawString(mStack, Minecraft.getInstance().font, text, width / 2, height / 2, Integer.parseInt("33AA66", 16));
            }
        });
    }
}

"Call from net.minecraftforge.fml.event.lifecycle.FMLClientSetupEvent."

I found it. One step further!

I don't think FMLClientSetupEvent is reached. The other classes are untouched. What did I do wrong this time?

public class GuiHandler {
    String text = "Hello world!";
    @SubscribeEvent
    public void onRenderGui(FMLClientSetupEvent event)
    {System.out.println("bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb");
        OverlayRegistry.registerOverlayBottom("hello", new IIngameOverlay() {
            @Override
            public void render(ForgeIngameGui gui, PoseStack mStack, float partialTicks, int width, int height) {
                drawString(mStack, Minecraft.getInstance().font, text, width / 2, height / 2, Integer.parseInt("33AA66", 16));
            }
        });
    }
}

I think I registered the GuiHandler event handler here.

public class ClientSideOnlyModEventRegistrar {
    private final IEventBus eventBus;
    public ClientSideOnlyModEventRegistrar(IEventBus eventBus) {
        this.eventBus = eventBus;
    }
    public void registerClientOnlyEvents() {
        eventBus.register(GuiHandler.class);
    }
}

I called the registrar above here.

@Mod(Chants2.MODID)
public class Chants2 {
    public static final String MODID = "chants2";
    public Chants2(){
        final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
        final ClientSideOnlyModEventRegistrar clientSideOnlyModEventRegistrar = new ClientSideOnlyModEventRegistrar(modEventBus);
        DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> clientSideOnlyModEventRegistrar::registerClientOnlyEvents);
    }
}

I guessed from reading the documentation on FMLClientSetupEvent that said to use Dist.CLIENT.

It worked! Thank you for guiding me, diesieben07.

If I have @EventBusSubscriber for my client-only event handlers, do I still have to call them in my Chants2 constructor?

I'll paste my code here for when I have to look back.

@Mod(Chants2.MODID)
public class Chants2 {
    public static final String MODID = "chants2";
    public Chants2(){
        final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();
        final ClientSideOnlyModEventRegistrar clientSideOnlyModEventRegistrar = new ClientSideOnlyModEventRegistrar(modEventBus);
        registerCommonEvents(modEventBus);
        DistExecutor.safeRunWhenOn(Dist.CLIENT, () -> clientSideOnlyModEventRegistrar::registerClientOnlyEvents);
    }
    public void registerCommonEvents(IEventBus eventBus) {
        //eventBus.register(GuiHandler.class);
    }
}

//@Mod.EventBusSubscriber(Dist.CLIENT)
public class ClientSideOnlyModEventRegistrar {
    private final IEventBus eventBus;
    public ClientSideOnlyModEventRegistrar(IEventBus eventBus) {
        this.eventBus = eventBus;
    }
    public void registerClientOnlyEvents() {
        eventBus.register(GuiHandler.class);
    }
}

//@Mod.EventBusSubscriber(Dist.CLIENT)
public class GuiHandler {
    static String text = "Hello world!";
    @SubscribeEvent
    public static void onRenderGui(FMLClientSetupEvent event)
    {
        OverlayRegistry.registerOverlayBottom("hello", new IIngameOverlay() {
            @Override
            public void render(ForgeIngameGui gui, PoseStack mStack, float partialTicks, int width, int height) {
                drawString(mStack, Minecraft.getInstance().font, text, width / 2, height / 2, Integer.parseInt("33AA66", 16));
            }
        });
    }
}
