[1.10.2] Render fluid level in tank with TESR


Guest

Recommended Posts

I am trying to render fluid inside a tank block with a TESR. The fluid I am trying to render in my tests is either water or lava.

 

This is my TESR:

    public void renderTileEntityAt(TileEntityFluidTank te, double x, double y, double z, float partialTicks, int destroyStage)
    {
        GlStateManager.pushMatrix();
        int capacity = te.getFluidHandler().getCapacity();
        FluidStack fluid = te.getFluidHandler().getFluid();
        if (fluid != null)
        {
            Tessellator tess = Tessellator.getInstance();
            VertexBuffer buffer = tess.getBuffer();

            buffer.setTranslation(x, y, z);

            bindTexture(TextureMap.LOCATION_BLOCKS_TEXTURE);
            TextureAtlasSprite still = Minecraft.getMinecraft().getTextureMapBlocks().getAtlasSprite(fluid.getFluid().getStill().toString());
            TextureAtlasSprite flow =  Minecraft.getMinecraft().getTextureMapBlocks().getAtlasSprite(fluid.getFluid().getFlowing().toString());

            double posY = .1 + (.8 * ((float) fluid.amount / (float) capacity));
            float[] color = ClientUtils.getRGBAFloatArrayFromHexColor(fluid.getFluid().getColor(fluid));

            buffer.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION_TEX_COLOR);
            buffer.pos( 4/16, posY,  4/16).tex(still.getInterpolatedU( 4), still.getInterpolatedV( 4)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos(12/16, posY,  4/16).tex(still.getInterpolatedU(12), still.getInterpolatedV( 4)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos(12/16, posY, 12/16).tex(still.getInterpolatedU(12), still.getInterpolatedV(12)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos( 4/16, posY, 12/16).tex(still.getInterpolatedU( 4), still.getInterpolatedV(12)).color(color[0], color[1], color[2], color[3]).endVertex();
            tess.draw();

            buffer.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION_TEX_COLOR);
            buffer.pos(12/16, 1/16, 12/16).tex(flow.getInterpolatedU(12), flow.getInterpolatedV(15)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos(12/16, posY, 12/16).tex(flow.getInterpolatedU(12), flow.getInterpolatedV( 1)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos( 4/16, posY, 12/16).tex(flow.getInterpolatedU( 4), flow.getInterpolatedV( 1)).color(color[0], color[1], color[2], color[3]).endVertex();
            buffer.pos( 4/16, 1/16, 12/16).tex(flow.getInterpolatedU( 4), flow.getInterpolatedV(15)).color(color[0], color[1], color[2], color[3]).endVertex();
            tess.draw();

            buffer.setTranslation(0, 0, 0);
        }
        GlStateManager.popMatrix();
    }

 

This code currently only renders two sides of the five sides that need to be rendered (or at least it should). Instead of rendering the water or lava texture, it renders nothing.

Two things, did you bind the TESR, and the next being did you let the client know that there is a fluid inside of it.

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

You are using integer division everywhere (

12/16

), which will always be rounded down (12/16 = 0.75 = 0). To do proper division with decimals, use

floats

(12F/16F = 0.75F).

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.
