Set random metadata for blocks on load?

[doku]

I'm using metadata to give grass blocks a random texture index.  So far I've managed to get this working using 'onBlockAdded'.  However I would need the metadata value to be given to existing blocks in the world ( when world is loaded?) , not just ones that are added.  How would I go about doing this, or is there another approach I can take?

not sure (haven't used it) but have a look at ChunkEvent. also if you'll be replacing all dirt blocks on chunk load it might cause lags.

Thanks, I will take a look at the event. 

 

I potentially have another way of achieving what I'm trying to do but I have one issue.  How do I reference 'the world' in a Block class?  I'm trying to retrieve the chunk in which a block exists using this line :

 

    @Override
public int getBlockTexture(IBlockAccess iBlock, int x, int y, int z, int side)
{    	
    	 Chunk chunk = Chunk.worldObj.getChunkFromBlockCoords(x,z);

 

However 'Chunk.worldObj' throws up the error “Cannot make a static reference to the non-static field Chunk.worldObj”

 

Suggestions?
