I have a wall that I've made and I want the texture on top to rotate base on the direction the wall is facing. I also want to change the texture if the wall is a post rather than a connector. How would I do this?

You will need a custom block renderer (using ISimpleBlockRenderingHandler).

Then before you draw your Block (possibly using renderBlockWall in the RenderBlocks instance you get) you set uvRotateTop in that same RenderBlocks to a value 0-3 to rotate the top texture. Set it to 0 again afterwards.

Do you know a tutorial? If not where do I register the renderer and what vanilla class could I reference?

I don't know of a tutorial, but all your renderWorldBlock method needs to do is set the rotation and then call the original renderBlockWall method.

You register your ISBRH with FMLs RenderingRegistry class.

 

OK, I'm not that familiar with ISBRH so how do I detect what direction the block is facing? And how would I rotate the texture after that?

world#getBlockMetadata?

Well the wall I have already has other walls with metadata. And the world param isn't actually world. It can't detect that stuff.

world#getBlockMetadata?

IBlockAccess still has getBlock and getBlockMetadata.

 

Point is:

If you want to change the rotation to a specific direction, you're going to need to figure out what defines that specific direction yourself.  No one else can say "oh just do X" because you're the one who wants something specific based on parameters only you know.

 

If its based on which direction the player was facing when they placed it down you're either going to have to save it in the metadata or use a TileEntity.  There are no ifs, ands, or buts about it.  The game isn't magic and can't interpret what you say into what you mean unless you are clear and unambiguous.

I don't want it to be determined by the way the player was facing, I want the way the wall is connected to adjacent walls to determine the rotation of the texture.

Then you're going to need to know if there's a wall at XPos, ZPos, XNeg, or ZNeg.  world#getBlock

Then how do I re-set the the texture of a block after i check that?

No I want to change the texture when I check it.

This is really pointless. Nothing works and I'm not getting anywhere
