Thank you for your advice, including the application examples! I can use "bilt" as opposed to "fill". Your way will certainly solve my problem.

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; @Mod(RectMod.MODID) public class RectMod { public static final String MODID = "rectmod"; public RectMod(){ } @Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD) public static class ClientModEvents { @SubscribeEvent public static void registerGuiOverlays(RegisterGuiOverlaysEvent event) { event.registerAboveAll("bar", BAR); } } public static final IGuiOverlay BAR = ((gui, guiGraphics, partialTick, screenWidth, screenHeight) -> { RenderSystem.setShader(GameRenderer::getPositionColorShader); // 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. https://gist.github.com/QbismX/fc43dcbcca419336d89d8670ef52a101

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) -> { RenderSystem.setShader(GameRenderer::getPositionColorShader); guiGraphics.fill(100,120,140,160,0xFFFFFF); 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.
