I have made a new block, extending BlockPane. Initially, I had the texture set to the vanilla Iron Bars. This didn't require me to register any textures (obviously), just declare the already registered texture, when initialising the block, like so:

 

public static Block poweredFence = new REFence("iron_bars", "iron_bars", Material.rock, false).setBlockName(Names.Traps.POWEREDFENCE);

 

Now that I have gotten the block functioning as I want it to, I am attempting to add my own texture to it. I tried registering the texture as normal, in the block class - and adjusting the block initialisation:

 

public static Block poweredFence = new REFence("powered_fence", "powered_fence", Material.rock, false).setBlockName(Names.Traps.POWEREDFENCE);

 

@SideOnly(Side.CLIENT)
    @Override
    public void registerBlockIcons(IIconRegister icon)
    {
        blockIcon = icon.registerIcon(this.getUnlocalizedName().substring(this.getUnlocalizedName().indexOf(".") + 1));
    }

 

This has worked for everything else I have done, and does retexture the in-hand icon, but when placed in the world the game crashes with a null pointer exception.

I know that I need to register the texture file, and the way I have it works, but I am not sure why it causes a crash when the block is placed.

I presume I need to register the icon somewhere else, though I am not sure where/how, as registering the icon in my client proxy was unsuccessful and I couldn't find a sufficient tutorial that explained/solved my problem.

 

Here is the crash report too:
