I can't seem to figure out how to render an animated liquid into a gui. In 1.7.10 it was easy, but I am unable to port it.

 

What I did for 1.7.10:

	private void drawFluidTank(IFluidTank tank, int x, int y){
        FluidStack fluid = tank.getFluid();
        TextureManager manager = mc.getTextureManager();
        if (fluid != null){
            manager.bindTexture(manager.getResourceLocation(0));
            float amount = fluid.amount;
            float capacity = tank.getCapacity();
            float scale = amount / capacity;
            int fluidTankHeight = 60;
            int fluidAmount = (int) (scale * fluidTankHeight);
            drawFluid(x, y + fluidTankHeight - fluidAmount, fluid.getFluid().getIcon(fluid), 16, fluidAmount);
        }
    }
    
private void drawFluid(int x, int y, IIcon icon, int width, int height){
        int i = 0;
        int j = 0;
        
        int drawHeight = 0;
        int drawWidth = 0;
        
        for (i = 0; i < width; i += 16){
            for (j = 0; j < height; j += 16) {
                drawWidth = Math.min(width - i, 16);
                drawHeight = Math.min(height - j, 16);
                drawTexturedModelRectFromIcon(x + i, y + j, icon, drawWidth, drawHeight);
            }
        }
    }

but I am unable to port it.

What are your issues?

What are your issues?

 

In 1.7.10 I used the IIcon but I have no idea what to do now. I am assuming I am supposed to use TextureAtlasSprite but I can't seem to get that to work either

this ?? https://github.com/CharsetMC/Charset/blob/1.9/src/main/java/pl/asie/charset/pipes/pipe/SpecialRendererPipe.java#L177-L178

Why not?

I see the problem now, I forgot to bind the blocks texture
