I've been trying to render a fluid to the gui. And referenced here.

But the result is this:

public class LavaGeneratorScreen extends AbstractContainerScreen<LavaGeneratorMenu> {
    private final ResourceLocation GUI = new ResourceLocation(GeneratorMod.MODID, "textures/gui/lava_generator_gui.png");

    public LavaGeneratorScreen(LavaGeneratorMenu menu, Inventory playerInv, Component title) {
        super(menu, playerInv, title);
    }

    @Override
    public void render(@NotNull PoseStack matrixStack, int mouseX, int mouseY, float partialTicks) {
        this.renderBackground(matrixStack);
        super.render(matrixStack, mouseX, mouseY, partialTicks);
        FluidStack fluid = menu.getFluid().copy();
        int maxFluid = menu.getMaxFluidAmount();
        renderFluid(matrixStack, fluid, maxFluid);
        this.renderTooltip(matrixStack, mouseX, mouseY);
    }

    private void renderFluid(@NotNull PoseStack matrixStack, FluidStack fluid, int maxFluid) {
        drawString(matrixStack, this.font, "fluid: " + fluid.getAmount() + " / " + maxFluid + " (" + fluid.getDisplayName().getString() + ")",
                10, 20, 0xFFFFFF);
        if (!fluid.isEmpty() && this.minecraft != null) {
            FluidAttributes fluidAttributes = fluid.getFluid().getAttributes();
            ResourceLocation fluidLoc = fluidAttributes.getFlowingTexture(fluid);
            TextureAtlasSprite fluidSprite = minecraft.getTextureAtlas(InventoryMenu.BLOCK_ATLAS).apply(fluidLoc);
            minecraft.getTextureManager().bindForSetup(new ResourceLocation(fluidLoc.getNamespace(), "textures/" + fluidLoc.getPath() + ".png"));
            int color = fluidAttributes.getColor();
            GlStateManager._clearColor(((color >> 16) & 0xFF) / 255f, ((color >> 8) & 0xFF) / 255f,
                    (color & 0xFF) / 255f, ((color >> 24) & 0xFF) / 255f);
            int scaledHeight = Tools.scaled(fluid.getAmount(), maxFluid, 48);
            blit(matrixStack, this.leftPos + 98, this.topPos + 66 - scaledHeight, 0, 16, scaledHeight, fluidSprite);
        }
    }

    @Override
    protected void renderBg(@NotNull PoseStack matrixStack, float partialTick, int mouseX, int mouseY) {
        RenderSystem.setShaderTexture(0, GUI);
        this.blit(matrixStack, this.leftPos, this.topPos, 0, 0, this.imageWidth, this.imageHeight);
    }
}

What's wrong?

Rendering was successful, but it's a bit different from what I intended.

And what I intend is this.

in RenderFluid()
 

            FluidAttributes fluidAttributes = fluid.getFluid().getAttributes();
            ResourceLocation fluidLoc = fluidAttributes.getStillTexture(fluid);
            RenderSystem.setShaderTexture(0, new ResourceLocation(fluidLoc.getNamespace(), "textures/" + fluidLoc.getPath() + ".png"));
            int color = fluidAttributes.getColor();
            RenderSystem.setShaderColor(((color >> 16) & 0xFF) / 255f, ((color >> 8) & 0xFF) / 255f,
                    (color & 0xFF) / 255f, ((color >> 24) & 0xFF) / 255f);
            int scaledHeight = Tools.scaled(fluid.getAmount(), maxFluid, 48);
            blit(matrixStack, this.leftPos + 98, this.topPos + 66 - scaledHeight, 0, 17, 16, scaledHeight);

Tools.scaled

    public static int scaled(float value, float maxValue, int height) {
        if (value <= 0 || maxValue <= 0) {
            return 0;
        }
        return (int) (value / maxValue * height);
    }

 

Ah! Okay. Thank you!

How can I get fluid texture's height?

Ah, I got.

                TextureAtlasSprite fluidSprite = minecraft.getTextureAtlas(InventoryMenu.BLOCK_ATLAS).apply(fluidLoc);
                int textureHeight = fluidSprite.getHeight();

It still renders the same.

private void renderFluid(@NotNull PoseStack matrixStack, FluidStack fluid, int maxFluid) {
        drawString(matrixStack, this.font, "fluid: " + fluid.getAmount() + " / " + maxFluid + " (" + fluid.getDisplayName().getString() + ")",
                10, 25, 0xFFFFFF);
        if (!fluid.isEmpty() && this.minecraft != null) {
            int scaledHeight = Tools.scaled(fluid.getAmount(), maxFluid, 48);
            if (scaledHeight > 0) {
                FluidAttributes fluidAttributes = fluid.getFluid().getAttributes();
                ResourceLocation fluidLoc = fluidAttributes.getStillTexture(fluid);
                TextureAtlasSprite sprite = minecraft.getTextureAtlas(InventoryMenu.BLOCK_ATLAS).apply(fluidLoc);
                int color = fluidAttributes.getColor();

                int yCount = scaledHeight / 16;
                int yRemainder = scaledHeight % 16;

                RenderSystem.setShaderTexture(0, new ResourceLocation(fluidLoc.getNamespace(), "textures/" + fluidLoc.getPath() + ".png"));
                RenderSystem.setShaderColor(((color >> 16) & 0xFF) / 255f, ((color >> 8) & 0xFF) / 255f,
                        (color & 0xFF) / 255f, ((color >> 24) & 0xFF) / 255f);

                for (int i = 1; i <= yCount; i++) {
                    blit(matrixStack, this.leftPos + 98, this.topPos + 66 - 16 * i, 0, 16, 16, sprite);
                }
                blit(matrixStack, this.leftPos + 98, this.topPos + 66 - 16 * yCount - yRemainder, 0, 16, yRemainder, sprite);

                // reset color
                RenderSystem.setShaderColor(1f, 1f, 1f, 1f);
            }
        }
    }

(TextureAtlasSprite sprite = minecraft.getTextureAtlas(InventoryMenu.BLOCK_ATLAS).apply(fluidLoc);
The sprite height is just 16.)

You're binding the wrong texture. You have to bind the block atlas which you do with RenderSystem.setShaderTexture(0, InventoryMenu.BLOCK_ATLAS)

Ah, I should have bound InventoryMenu.BLOCK_ATLAS. Sorry.
