Same block, different textures

[jh62]

Hi.

 

I'm new to this minecraft modding thing.

 

I just want to know how do you change a block texture depending on the material you used to make the block, like wood or wool.

 

I already did what the metadata subblock forge tutorial says, but I don't know how to get the that data to the custom renderer I have for my custom models.

 

I made a table that uses the 4 different woods in the game and i register them properly and everything, but I don't understand how using metadata or something like that you can change it's texture according to it's material in the renderer class.

Somebody???

Have you looked at vanilla code?

Yes. I don't understand most of it. There is a lot of code in different classes and this is my first time modding for this game, so is kinda confussing.

 

I saw that items have ItemRenderer as a renderer?

 

I'm using TileEntityRenderer because ClientRegistry only has a method that accepts a TileEntityRenderer...

 

I don't know...

Block.java:

/**
     * From the specified side and block metadata retrieves the blocks texture. Args: side, metadata
     */
    public Icon getIcon(int par1, int par2)
    {
        return this.blockIcon;
    }

    {
        return this.blockIcon;
    }

 

Here's a thing a don't understand:

 

I followed a tutorial I've found (Im using minecraft 1.4.7 because I have some mods that are not compatible with newer versions yet) and the tutorial said this:

 

- Create a block as a BlockContainer.

- Create a ItemBlock for that Block.

- Register everything (Block, Item, Entity, Recipe).

- Bind a special renderer in ClientProxy with ClientRegistry.bindTileEntitySpecialRenderer...

 

Now, my custom renderer (as in the tutorial) it renders the following:

 

public void renderTileEntityAt(TileEntity tile, double d, double d1,
		double d2, float f)

 

So when I convert that TileEntity to a block, i get it's properties, but I cannot find a way to get the dammageValue when the ItemStack creates a new item (it creates an item and if it is Oak is assigns a dammageValue of 0, spruce 1, birch 2, jungle 3), so I need to get that data from the Block to bind different textures to the model I'm trying to render so if it is a OakTable it displays as Oak, etc...
