[1.5.1]Request for updated directional blocks tutorial

[GhostShadow]

I am looking for a general tutorial on how to make directional blocks like dispensers/chests/stairs.

I have Googled but no luck. The forge wiki is largely incomplete and outdated.

Thank you.

Um, why not look at the vanilla blocks?

I asked for tutorial.

I went through Furnace, piston etc.

I didnt really understand this

 

private void setDispenserDefaultDirection(World par1World, int par2, int par3, int par4)
    {
        if (!par1World.isRemote)
        {
            int l = par1World.getBlockId(par2, par3, par4 - 1);
            int i1 = par1World.getBlockId(par2, par3, par4 + 1);
            int j1 = par1World.getBlockId(par2 - 1, par3, par4);
            int k1 = par1World.getBlockId(par2 + 1, par3, par4);
            byte b0 = 3;

            if (Block.opaqueCubeLookup[l] && !Block.opaqueCubeLookup[i1])
            {
                b0 = 3;
            }

            if (Block.opaqueCubeLookup[i1] && !Block.opaqueCubeLookup[l])
            {
                b0 = 2;
            }

            if (Block.opaqueCubeLookup[j1] && !Block.opaqueCubeLookup[k1])
            {
                b0 = 5;
            }

            if (Block.opaqueCubeLookup[k1] && !Block.opaqueCubeLookup[j1])
            {
                b0 = 4;
            }

            par1World.setBlockMetadataWithNotify(par2, par3, par4, b0, 2);
        }
    }

 

I started yesterday, maybe it will take a while.

Have you programmed java or any other programming language before? If not, you need to learn it first before you can start modding.

 

I have a decent experience of java. I was just looking for some tutorials as it saves a lot of time

Well if you know your java then it shouldt be a problem

So what line(s) of the above code does you not understand ?

What is Block.opaqueCubeLookup? ...and what it has to do with find the direction?

It's a static class level function that lets you lookup if a given block (by ID) is opaque or not.  In Eclipse you can mouse-over and function, variable, or class name and see the relevant information about it (if any) and there's a little red/green icon next to the definition in the yellow popup box, that if clicked on, will take you to where that function, class, or variable is declared.

 

As for what it has to do with direction:

It's a dispenser.  It's figuring out which direction it can face without facing a solid block.
