draw rectangle on gui


Recommended Posts

I want to add rectangle on screen. But I don't know how to draw rectangle. 

I make the following code.:

public static void IGuiOverlay BAR = ((gui, guiGraphics, partialTick, screenWidth, screenHeight) -> {



guiGraphics.drawString(Minecraft.getInstance().font, "test", 100, 140, 0xFFFFFF, true);



Then, String "test" is displayed on the screen. But a rectangle is not displayed.

Please give me your advice.

Don't post code snippets out of context in the forum.

Create a small build on github that reproduces your problem.


Guess (I should not have to guess):



I am not familiar with that method, but looking at the code it takes an ARGB value not an RGB

So I guess your alpha value is zero and the blending/transparency means nothing is displayed?


See for example, Gui.drawBackdrop() or displayScoreboardSidebar() which also has code to take into account the user's choice of background opacity.

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.

I do apologize for any inconvenience caused. I had been unaware of rule in the forum. Thank you for pointing this out.

I don't care opacity. 

"fill" is the method in net/minecraft/client/gui/GuiGraphics.java   

I refer from Screen - Forge Documentation (minecraftforge.net)

I make the following code. I am able to display the text to appear in a similar method to the problematic method. I don't know what these methods need respectively.

package com.QbismX.RectMod.main;

import com.mojang.blaze3d.systems.RenderSystem;
import net.minecraft.client.Minecraft;
import net.minecraft.client.renderer.GameRenderer;
import net.minecraftforge.client.event.RegisterGuiOverlaysEvent;
import net.minecraftforge.client.gui.overlay.IGuiOverlay;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;

public class RectMod {

    public static final String MODID = "rectmod";

    public RectMod(){

    @Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD)
    public static class ClientModEvents {

        public static void registerGuiOverlays(RegisterGuiOverlaysEvent event) {
            event.registerAboveAll("bar", BAR);


    public static final IGuiOverlay BAR = ((gui, guiGraphics, partialTick, screenWidth, screenHeight) -> {


        // Maybe this draw a rectangle on the screen.
        // First, second, third and fourth arguments may set a position.
        // Fifth argument may set color.
        guiGraphics.fill(100, 120, 140, 160, 0xFFFFFF);

        // This draw text on the screen. The method have no problem.
        // Third and fourth arguments set a position.
        // Fifth argument sets text color.
        // Sixth argument sets shadow.
        guiGraphics.drawString(Minecraft.getInstance().font, "test", 100, 140, 0xFFFFFF, true);



Please allow me to share the files debug.log, launcher_log.txt and RectMod.java with you at this link.

    • I tried to play a mod for forge 1.20.2 and the mod didn't work, fix this please.
    • EntityRenders requires an EntityRenderProvider. This is what I have: @Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void clientSetup(FMLClientSetupEvent event) { EntityRenderers.register(HOSE.get(), new HoseEntityRenderFactory()); } private static class HoseEntityRenderFactory implements EntityRendererProvider<HoseEntity> { @Override public EntityRenderer<HoseEntity> create(Context context) { return new HoseEntityRenderer<>(context); } } } Replace HoseEntity with your own entity. If you're doing multiple try doing generics (though untested).
    • First off, I know should probably be able to debug this on my own, but this is my first mod, and I couldn't figure it out for multiple days now. What I'm trying to do, is to modify the default minecart by replacing it with a slightly different version, but I'm stuck 1 step before that, that being "cloning" the minecart as a separate Entity/Item. Here you can see a GitHub gist of all relevant files: https://gist.github.com/Kipama/cd39127e8891715a3006fa990ca7ff14 If there are files missing or access isn't working as intended, please let me know! In the Gist you can find the following files: -CustomMinecartEntity.java:        This file extends AbstractMinecart and is a clone of the vanilla minecart entity. I know I should override the minecart entity directly, but as this should work rn, I didn't change it yet. -CustomMinecartRenderer.java:  Basically vanilla MinecartRenderer with a Custom slapped on it, extends MinecraftRenderer. -ModEntities.java:                         This is where the new Entity gets added to the deferred register ENTITY_TYPES. -ModernMinecarts.java:               The main mod file. Relevant part is at the bottom, where I try to use onClientSetup to register the new Entity using EntityRenderers.register(). That last part is where my problem begins. When I try to register the new entity using EntityRenderers.register(ModEntities.CUSTOM_MINECART_ENTITY.get(), CustomMinecartRenderer::new); I get a syntax Error saying the provided and required types don't match. These are the required and provided types: ModEntities.CUSTOM_MINECART_ENTITY.get(): Required: EntityType<? extends T> Provided:EntityType<CustomMinecartEntity> CustomMinecartRenderer::new: Required: EntityRendererProvider<T> Provided:<method reference   So far I looked at 2 different Git repositories implementing custom entities, but haven't been able to figure out what I'm doing wrong. Any answers, suggestions and ridicules appreciated.
    • Yes, it is. I found out how to do it. (for Forge 1.20.1) Add this to main class constructor: // ... MinecraftForge.EVENT_BUS.<PlayerInteractEvent.EntityInteract>addListener(e -> { Player playerWhoUsed = e.getEntity(); ItemStack usedItemStack = e.getItemStack(); Entity entityThatWasClicked = e.getTarget(); if (usedItemStack.getItem() instanceof YourItem item) { // your code... e.setCancelled(true); // you can remove this if you want to continue interaction } } // ...
    • Hi there, I'm hoping to create a block that renders a fake skybox, blocking anything behind it. There are a couple of mods that already do this, but they are very outdated. One example: https://github.com/Elix-x/Skyblocks/ https://www.curseforge.com/minecraft/mc-mods/skyblocks I'm not familiar enough with rendering to be able to port it. Is there anyone who can point me in the right direction? Any help would be appreciated.
