How could i make a custom block that would use the textures of a vanilla block and also if a texture pack is used, the custom block to use the texture for the vanilla block from the texture pack ?

Block.name_of_block_you_want.getIcon(side, metadata)

Try this in your custom block class:

    @Override
    public void registerIcons(IconRegister reg)
    {
    	this.blockIcon = reg.registerIcon("filename of the texture from the block you want");
    }

For the textures go to mcp/temp/bin/minecraft/textures/blocks

Press CRTL+SHIFT+O to import everything necessary.

Bad bad bad bad.

 

This duplicates the icon in the sprite sheet, if you do it enough times you'll end up using up more texture memory.

I'm trying to do this too, but with an item. What would I use for that? Items don't have sides, and I don't think meta changes the appearance either so that's also not relevant.

Item.blah.getIconFromDamage(meta);

Item.blah.getIconFromDamage(meta);

 

RegisterIcon only accepts a string though, so I guess I need to use a different method to get my textures?

 

Also, is it possible to have one class for multiple items that does this, with a different texture per item? How would I differentiate the items, as they all have different IDs?

That is not true.

 

He says while providing no evidence.

You did the same Look at the registerIcon implementation. It first looks up the icon name in a hashMap to see if an Icon instance for it already exists.

 

*Bow*

Touche.

 

I hadn't looked at the icon registration system, merely looked at what other blocks do.  For instance, grass references the Dirt class to get its bottom-face icon, rather than reregistering it.

 

So I had assumed that was the "more correct" way of doing things for whatever reason.

No, like this:

public Icon getIconFromDamage(meta){
    return Item.blah.getIconFromDamage(meta); //or switch, if you want to differentiate between meta
}

No registration necessary.
