Texture Overlay?

How can i make a "Overlay" to a block with the normal ...

@SideOnly(Side.CLIENT)
public void registerIcons(IconRegister par1IconRegister)
{


            this.Overlay = par1IconRegister.registerIcon("FjonGCraft:AnimatedBlocks/test");
            this.iconArray = par1IconRegister.registerIcon("FjonGCraft:AnimatedBlockOverlay/" + getBlockOverlay);
          }

What the block look like

What the Block Should look like

U can see i have tried, but the only thing i can see ingame is the "block overlay", the blockbackground i missing...

but i cant find the problem...

Please leave an answer... ...

I come so far:

[embed=425,349]package com.thefjong.tf.core;

import net.minecraft.block.Block;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IconRegister;

import net.minecraft.util.Icon;

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

public class ISidedAnimatedTextureBlock extends Block{

public static String getBlockOverlay;

Icon icons[];

public ISidedAnimatedTextureBlock(int par1, Material par2Material, String GetOverlay ){

super(par1, par2Material);

GetOverlay = getBlockOverlay;

icons = new Icon[2];

}

@SideOnly(Side.CLIENT)

public void registerIcons(IconRegister par1IconRegister)

{

          icons[0] = par1IconRegister.registerIcon("FjonGCraft:AnimatedBlocks/test");

            icons[1] = par1IconRegister.registerIcon("FjonGCraft:AnimatedBlockOverlay/" + getBlockOverlay);

    }

public int getRenderBlockPass()

    {

        return icons.length;

    }

public boolean canRenderInPass(int pass)

    {

        return pass == this.getRenderBlockPass();

    }

}

[/embed]

public int getRenderBlockPass()
    {
        return icons.length;
    }


public boolean canRenderInPass(int pass)
    {
        return pass == this.getRenderBlockPass();
    }

There are only two passes for blocks: 0 and 1.

icons.length returns 2, so nothing is rendered.

What you probably want:

public int pass;

public int getRenderBlockPass()
    {
        return this.pass;
    }

@Override
public boolean canRenderInPass(int pass)
    {
        this.pass = pass;
        return true;
    }

The block will be rendered twice, with the pass variable indicating which pass (0 or 1) is occurring.

You can then use this variable in your block renderer.
