Forge and vanilla code is attached as a library in your IDE. Find it and open it to browse the code.

Where i can find it in eclipse

This is not an Eclipse support forum. If I remember correctly, Eclipse will list libraries under "Referenced Libraries".

if you are looking for simple rotation, then stairs may not be the best example. Stairs rotate, but also can be placed upside down and their bounding boxes change.

 

1) add property facing to your block

 public static final PropertyDirection FACING = BlockHorizontal.FACING;

2) set default blockstate in the block constructor

this.setDefaultState(this.blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH));

3) create the proper blockstatecontainer

@Override
	protected BlockStateContainer createBlockState() {
		 return new BlockStateContainer(this, new IProperty[] { FACING});
	}

4) meta-> blockstate and blockstate->meta. a meta value is store with each blockstate. you have to convert this to and from the blockstate property value (below is taken from one of my blocks with other properties removed manually without testing, but think it is ok)

@Override
	public IBlockState getStateFromMeta(int meta) {
		
		EnumFacing enumfacing = EnumFacing.getFront(meta);

	        if (enumfacing.getAxis() == EnumFacing.Axis.Y)
	        {
	            enumfacing = EnumFacing.NORTH;
	        }
	        
	        

	        return this.getDefaultState().withProperty(FACING, enumfacing);
	}
	@Override
	public int getMetaFromState(IBlockState state) {
		
		EnumFacing facing=state.getValue(FACING);
		
		int meta=((EnumFacing)state.getValue(FACING)).getIndex();
		
		return meta;
	}
	

5)set the property values in the blockstate json. (the "mod" is your modid, the "model" is your model json which should be located in assets/[mod]/models/block. If you wanted different models for different directions, just change here.

{
    "variants": {
        "facing=north": { "model": "mod:model" },
        "facing=east":  { "model": "mod:model", "y": 90 },
        "facing=south": { "model": "mod:model", "y": 180 },
        "facing=west":  { "model": "mod:model", "y": 270 },
        
    }
}

 

I think that is all you need. Good luck. Don't get discouraged modding, once you get used to looking into the minecraft code, it gets easier.

There are tutorials out there. Just put some time into your problem before posting here. People (often the same people) have answered the same questions over and over and over again. If your issue looks like you thought it through and did some research, people will be more helpful (in general).

	}

 

This is over-engineered. The check for the Axis being Y and setting the facing to North isn't really needed. The only way this could ever happen is if you used external tools to force the block metadata to be something other than what the allowable states are.

 

Use EnumFacing.getHorizontal(meta) instead.

Quote

	@Override
	public int getMetaFromState(IBlockState state) {
		EnumFacing facing=state.getValue(FACING);
		int meta=((EnumFacing)state.getValue(FACING)).getIndex();
		return meta;
	}

 

 

This is likewise over-engineered copy paste "I don't know what the fuck I'm doing" garbage. You created a local facing variable and then don't even use it. You even cast the property to an EnumFacing (why?) and use getIndex, which is wrong. No wonder you have to fix things with the getAxis == Y....

 

return state.getValue(BlockHorizontal.FACING).getHorizontalIndex();

As i copyed aw_wolfe´s stuff into my block-class, i get purple, black blocks instead of my model, if I placing it in my Minecraft-test-world.

 

I don´t know, what exactly i have to replace with the lines, you show here as a better choice...
