So in my dimension, I have been coding a structure, just a simple little house with a stair-peak roof. Unfortuantely, when I add the stairs, they all face the same direction. I know this has to do with blockstates but I have no idea how to use those in 1.8. Any help?

P.S. also I'd like to make my own custom stairs but have no idea how to do the blockstates or whatever. would extends some staircase class do it?

When you set the block state, you need to also set the FACING property:

IBlockState state = Blocks.oak_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.NORTH);

It's up to you, of course, to figure out which facing each block will need. You can also set the HALF (top or bottom) and SHAPE (e.g. straight or one of the corners).

Thanks, I just had to modify it to this:

 

world.setBlockState(pos, Blocks.nether_brick_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.SOUTH));

 

and my structure now generates a staircase roof. However, the x == 0 side isn't generating? any ideas?

However, the x == 0 side isn't generating? any ideas?

Not without seeing some code, no.

Sorry, My bad:

for(y = 7; y< 8; y++){

                for(int x = 0; x<7; x++){

                //    BlockPos corner = pos;

                    for(int z=0; z<8; z++){

                        pos = new BlockPos(startX + x, startY + y, startZ + z);

                        if(x == 0){

                            // Set edge blocks to brick

                        world.setBlockState(pos, Blocks.nether_brick_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.EAST));

                        }

                        else if(z == 0){

                            // Set edge blocks to brick

                            world.setBlockState(pos, Blocks.nether_brick_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.SOUTH));

                         

                        }

                        else if(z == 7){

                            // Set edge blocks to brick

                            world.setBlockState(pos, Blocks.nether_brick_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.NORTH));

                        }

                        else if(x == 7){

                            // Set edge blocks to brick

                        world.setBlockState(pos, Blocks.nether_brick_stairs.getDefaultState().withProperty(BlockStairs.FACING, EnumFacing.WEST));

                        }

                        else{

                            // Leave other blocks as air

                            world.setBlockState(pos, Blocks.air.getDefaultState());

                        }

                    }

                }

That looks like it should work, although the for loop for the 'y' axis is superfluous as it only iterates once.

 

Do you have any calls to setBlockState after your for loops finish that could be overriding the x == 0 position with a different block, e.g. air?

I checked, and while I found some duplicate code for the stairs, deleting it didn't change anything.
