I just want to render a overlay (i have creat a spyglass likt that from 1.17) and now i want to render the Overlay

this is the code of the event i used:

	@SubscribeEvent(priority = EventPriority.HIGHEST)
	public static void RenderSpyglassOverlay(RenderGameOverlayEvent event) {
		
		PlayerEntity player = Minecraft.getInstance().player;
		int posX = event.getWindow().getScaledWidth() / 2;
		int posY = event.getWindow().getScaledHeight() / 2;

		if (player.getActiveItemStack().getItem() == CaveItems.SPYGLASS.get()) {
			
			RenderSystem.disableDepthTest();
			RenderSystem.depthMask(false);
			RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F);
			RenderSystem.disableAlphaTest();
			Minecraft.getInstance().getTextureManager().bindTexture(new ResourceLocation("cave:textures/misc/spyglass_scope.png"));
			Minecraft.getInstance().ingameGUI.blit(event.getMatrixStack(), posX - 128, posY - 128, 0, 0, posX * 2, posY * 2, 256, 256);
			RenderSystem.depthMask(true);
			RenderSystem.enableDepthTest();
			RenderSystem.enableAlphaTest();
			RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F);

			
		}
		
	}

but the overlay looks like this:

so my question:

1 .how to render the game overlay translucent

2. how to set the outside of the overlay to black

1 You need to enable blend.

2 I think you should be able to just use fill and fill the whole bg.

there is no fill method

Last time I checked is still there, AbstractGui.fill()
