1.10 using EnumFacing with all 6 directions

Recommended Posts

I have this code

	public IBlockState getStateFromMeta(int meta)
	{
		IBlockState iblockstate = this.getDefaultState();
		   /**
	     * Get the Index of this Facing (0-5). The order is D-U-N-S-W-E
	     */
		switch(meta) {
			case 0:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.DOWN);
				break;
			case 1:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.UP);
				break;
			case 2:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.NORTH);
				break;
			case 3:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.SOUTH);
				break;
			case 4:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.WEST);
				break;
			case 5:
				iblockstate = iblockstate.withProperty(FACING,EnumFacing.EAST);
				break;				
			
		}

		return iblockstate;
	}

 

Isn't there a better way to do this?  There is the  "EnumFacing.getHorizontal(meta))" but i need the UP and DOWN also

Have you tried a simple iteration over the enum's values, comparing to their ordinals?

 

for (EnumFacing face : EnumFacing.values()) {
	if (meta == face.ordinal()) {
		iblockstate = iblockstate.withProperty(FACING, face);
		break;
	}
}

Or, even smaller, just use the array index directly:

iblockstate = iblockstate.withProperty(FACING, EnumFacing.values()[meta]);

You might want to do some sanitizing on that version, but it's pretty concise as-is.

Whatever Minecraft needs, it is most likely not yet another tool tier.

Seriously?

Can't you people even look at the Enum? Or other blocks that use it?

EnumFacing.getFront(meta)

 


    /**
     * Get a Facing by it's index (0-5). The order is D-U-N-S-W-E. Named getFront for legacy reasons.
     */
    public static EnumFacing getFront(int index)
    {
        return VALUES[MathHelper.abs(index % VALUES.length)];
    }

The takeaway lesson here: Use your IDE to explore and walk through the vanilla classes to see:

 

  • A) What's on offer.
  • B) How vanilla uses things

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

I solved it this way on block placing

 

Horizontal placing, like furnace.

	@Override
	public IBlockState onBlockPlaced(World worldIn, BlockPos pos, EnumFacing blockFaceClickedOn, float hitX, float hitY, float hitZ, int meta, EntityLivingBase placer)
	{
		  // find the quadrant the player is facing
		EnumFacing enumfacing = (placer == null) ? EnumFacing.NORTH : EnumFacing.fromAngle(placer.rotationYaw);

		  // Place allways same up and down direction
		return this.getDefaultState().withProperty(PROPERTYFACING, enumfacing);
	}		  		

 

 

And every direction placing, like piston

	@Override
	public IBlockState onBlockPlaced(World worldIn, BlockPos pos, EnumFacing blockFaceClickedOn, float hitX, float hitY, float hitZ, int meta, EntityLivingBase placer)
	{
		  return this.getDefaultState().withProperty(PROPERTYFACING, BlockPistonBase.getFacingFromEntity(pos, placer));
		  
	}

Sigh.

 

public static final PropertyDirection PROPERTYFACING = BlockHorizontal.FACING;

 

Magic, you're done here. The property already exists, utilize it.

    • After uninstalling this mod, everything works! Thanks!
    • I had been playing on this fabric server for about a month with some friend and one day it just stopped starting, can anyone help me understand what the cause is? https://mclo.gs/2jop3r5    
    • The mobs are moving normally for a second, then freeze, then go back to normal, and this repeats. I describe this as mob lag, bc they stutter as if they were lagging. I don't have the best wifi, but that shouldn't matter since its 10mbps which is enough for a server. I have 8 gigs of ram for it, no optimizations have worked, if there is anything more you may need to help lmk, ill describe. The modlist is pretty hefty: VS_ClockworkSurvivalSupportV1.4 aether-1.20.1-1.2.0-neoforge.jar alexsdelight-1.5.jar alexsmobs-1.22.7.jar appleskin-forge-mc1.20.1-2.5.1.jar backpacked-forge-1.20.1-2.2.5.jar balm-forge-1.20.1-7.2.1.jar bettervillage-forge-1.20.1-3.2.0.jar BiomesOPlenty-1.20.1-18.0.0.598.jar botarium-forge-1.20.1-2.3.2.jar CGM-Unofficial-1.4.11+Forge+1.20.1.jar citadel-2.5.2-1.20.1.jar clockwork-1.20.1-0.1.2-forge-05f5d5fbbb.jar configured-forge-1.20.1-2.2.2.jar connectivity-1.20.1-4.9.jar create-1.20.1-0.5.1.f.jar create-new-age-forge-1.20.1-1.1.2.jar createarmoryv0.6.1n.jar createbigcannons-forge-1.20.1-0.5.3.b.jar createchunkloading-1.6.0-forge.jar createdeco-2.0.1-1.20.1-forge.jar createdieselgenerators-1.20.1-1.2h.jar createendertransmission-2.0.7-1.20.1.jar create_misc_and_things_ 1.20.1_4.0A.jar cristellib-1.1.5-forge.jar cupboard-1.20.1-2.3.jar curios-forge-5.7.0+1.20.1.jar destroy-1.20.1-0.8.jar Dungeon Crawl-1.20.1-2.3.14.jar FallingTree-1.20.1-4.3.4.jar FarmersDelight-1.20.1-1.2.4.jar framework-forge-1.20.1-0.6.26.jar geckolib-forge-1.20.1-4.4.2.jar InsaneLib-1.12.1-mc1.20.1.jar Jade-1.20.1-forge-11.8.0.jar jei-1.20.1-forge-15.3.0.4.jar journeymap-1.20.1-5.9.18-forge.jar JustEnoughResources-1.20.1-1.4.0.247.jar kotlinforforge-4.10.0-all.jar l2library-2.4.23.jar libraryferret-forge-1.20.1-4.0.0.jar macawsbridgesbop-1.20-1.1.jar mcw-bridges-2.1.0-mc1.20.4forge.jar moonlight-1.20-2.9.17-forge.jar morevillagers-forge-1.20.1-5.0.0.jar Mo_ZombiesWave-1.20.1-0.1.0-forge.jar NaturesCompass-1.20.1-1.11.2-forge.jar Placebo-1.20.1-8.6.1.jar refinedstorage-1.12.4.jar soundphysics-forge-1.20.1-1.1.2.jar spark-1.10.53-forge.jar stealing_villagers-forge-1.20.1-1.0.0.jar s_a_b-1.3.0_1.20.1.jar takesapillage-1.0.3-1.20.1.jar TerraBlender-forge-1.20.1-3.0.1.4.jar tombstone-1.20.1-8.6.2.jar Towns-and-Towers-1.12-Fabric+Forge.jar twilightforest-1.20.1-4.3.2145-universal.jar valkyrienskies-120-2.1.3-beta.1.jar veinmining-forge-1.3.0+1.20.1.jar waystones-forge-1.20-14.1.3.jar YungsApi-1.20-Forge-4.0.3.jar YungsBetterDesertTemples-1.20-Forge-3.0.3.jar YungsBetterDungeons-1.20-Forge-4.0.3.jar YungsBetterEndIsland-1.20-Forge-2.0.5.jar YungsBetterJungleTemples-1.20-Forge-2.0.4.jar YungsBetterMineshafts-1.20-Forge-4.0.4.jar YungsBetterNetherFortresses-1.20-Forge-2.0.5.jar YungsBetterOceanMonuments-1.20-Forge-3.0.4.jar YungsBetterStrongholds-1.20-Forge-4.0.3.jar YungsBetterWitchHuts-1.20-Forge-3.0.3.jar YungsBridges-1.20-Forge-4.0.3.jar zaynens_leather_from_rotten_flesh_mod_1.20.1.jar
    • Thank you so much! Unfortunately before reading this I reinstalled my java installer. Now when I try to open the forge installer I receive an error message stating 'Unable to install Java' even though I have definitely downloaded and installed the latest version. Any idea what this could be or how I could fix it?  
    • IT WORKED! THANK YOU!
