New Block Render Type?

[Alix_The_Alicorn]

I'm trying to make a new version of the lever, and like the lever it doesn't need a tile entity. So I need a way to custom render (like the lever) without making a TileEntity. I figured out that the lever is rendered by this code

public boolean renderBlockLever(Block p_147790_1_, int p_147790_2_, int p_147790_3_, int p_147790_4_)
    {
        int var5 = this.blockAccess.getBlockMetadata(p_147790_2_, p_147790_3_, p_147790_4_);
        int var6 = var5 & 7;
        boolean var7 = (var5 &  > 0;
        Tessellator var8 = Tessellator.instance;
        boolean var9 = this.hasOverrideBlockTexture();

        if (!var9)
        {
            this.setOverrideBlockTexture(this.getBlockIcon(Blocks.cobblestone));
        }

        float var10 = 0.25F;
        float var11 = 0.1875F;
        float var12 = 0.1875F;

        if (var6 == 5)
        {
            this.setRenderBounds((double)(0.5F - var11), 0.0D, (double)(0.5F - var10), (double)(0.5F + var11), (double)var12, (double)(0.5F + var10));
        }
        else if (var6 == 6)
        {
            this.setRenderBounds((double)(0.5F - var10), 0.0D, (double)(0.5F - var11), (double)(0.5F + var10), (double)var12, (double)(0.5F + var11));
        }
        else if (var6 == 4)
        {
            this.setRenderBounds((double)(0.5F - var11), (double)(0.5F - var10), (double)(1.0F - var12), (double)(0.5F + var11), (double)(0.5F + var10), 1.0D);

        }
        else if (var6 == 1)
        {
            this.setRenderBounds(0.0D, (double)(0.5F - var10), (double)(0.5F - var11), (double)var12, (double)(0.5F + var10), (double)(0.5F + var11));
        }
        else if (var6 == 0)

        return true;
    }

in RenderBlocks.java, because render type 12 is specified in BlockLever.java. I have not been able to figure out how to add a new RenderBlocks type dealio and I also have not been able to figure out where it says returning 12 in func_149645_b (I'm in 1.7.2) makes it render the lever as that code up there. Any help with understanding how this works would help, but if anyone with experience doing something like I am trying to do, that would be even more helpful.

Hi

 

The ISBRHandler is described in more detail here

http://greyminecraftcoder.blogspot.com.au/p/list-of-topics.html

 

The sections on Block Rendering will be of greatest interest, some specifics on the ISBRH here:
