Help again!! With switching metadata based on player direction!!!


Recommended Posts

Hey guys. It's me. Again! Last time I asked for help, I didn't get any help, so once again. I need to make a function that will check where the player is pointing at(south, Southeast, east and so on...) and to check which metadata of the block is placed. I can't explain so well with what do I need help. So here is the thing for one block: first and the second metadata of blocks are regular blocks. They have no special things. So the third metadata has an arrow texture on top of it pointing at north, the fourth should be pointing at Northwest and so on. I have made all these textures. So if the player places the block with the third metadata while his pointing at west, the metadata placed on the world will be fifth one or number 4. Can you help me guys, please! If you don't understand what I just have written then I'll explain it again.

I'm not really sure how you're doing this, but I tested out a command to return the f: value in the F3 menu (Tells if you're facing north/south/east/west)  I haven't done much with blocks, so I'm not really sure if its possible to get the username or EntityPlayer of the person who placed it.

 

//ICommandSender is used in commands... Which is what I tested this out on.
//EntityPlayer.rotationYaw is what contains the direction
    EntityPlayer player =  MinecraftServer.getServer().getConfigurationManager().getPlayerForUsername(icommandsender.getCommandSenderName());
    icommandsender.sendChatToPlayer(ChatMessageComponent.func_111066_d(String.valueOf(player.rotationYaw)));

 

And that should send a message of a value between -359 and +359... in order to make sure you get the right value just do something like

 

float yaw = player.rotationYaw;
if(yaw < 0)
    yaw += 360;

 

Anyways, the values would be

 

0 = South

90 = West

180 = North

270 = East

 

And you should be able to figure out the half-directions from there.

You can get the direction and save it into the metadata with this code :

 

 int metadata = par1World.getBlockMetadata(par2, par3, par4);
        int playerDirection = MathHelper.floor_double((double)((par5EntityLivingBase.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        if(metadata == 0)
        {
            switch(playerDirection)
            {
                case 0: metadata += 2; break; //South Facing Block = meta 2
                case 1: metadata += 3; break; //West Facing Block = meta 3
                case 2: metadata += 0; break; //North Facing Block = meta 0
                case 3: metadata += 1; break; //East Facing Block = meta 1
            }
        }
        par1World.setBlockMetadataWithNotify(par2, par3, par4, metadata, 3);
    }

 

Then you just have to

    • im stuck in a problem whit BlockEntities i cannot solve so im trying to work around it but in the less complex way possible  i think is posible to store data to the minecraft world  in older versions people talk about  WordDataSave i dont find anything about it for 1.20.4  i find a tutorial for player capability in 1.19    here is an event      //########## ########## ########## ##########     @SubscribeEvent     public static void onAttachCapabilitiesPlayer(AttachCapabilitiesEvent<Entity> event) {         if(event.getObject() instanceof Player) {             if(!event.getObject().getCapability(PlayerThirstProvider.PLAYER_THIRST).isPresent()) {                 event.addCapability(new ResourceLocation(mercmod.MOD_ID, "properties"), new PlayerThirstProvider());             }         }     }  soo i made this      //########## ########## ########## ##########     @SubscribeEvent     public static void onAttachCapabilitiesLevel(AttachCapabilitiesEvent<Level> event) {     } i think i can do some witchcraft  here  but is many things don't understand  to start whit i dont get yet how to recall the saved data from a BlockEntity  the handler still in progress the plan is to make a Map to store nbt data using the block coordinates as index later store that map as a big nbt      ########## any way the question is if theres alredy a tutorial for 1.20.4 for this ?? or some alredy working code from someone else doing something similar ?           
    • I tried this, and found out that Oculus is the mod that is crashing the game. I have removed it, and it now works fine! Thanks!
    • Hi @DanielderErbauer, I arrived here as I have the "as it does not exist in Block{minecraft:air}" error in a modpack I am trying to start. It's a long-shot, I know, but as the post that led this to being solved is missing, can I ask if you may recall what it said? Thanks in advance
    • Hm yeah sorry, not seeing anything else that's sticking out, I'd need to debug myself probably. Do you have a github or bitbucket repo? I could poke around when I have time to see what the problem might be.
    • looking around for the capabilities thing i found a piece of code and find this piece of code  //########## ########## ########## ########## @SubscribeEvent public static void addCustomTrades(VillagerTradesEvent event) { if(event.getType() == VillagerProfession.FLETCHER) { System.out.println("\n\n### VillagerProfession.FLETCHER \n\n");//<----------- Int2ObjectMap<List<VillagerTrades.ItemListing>> trades = event.getTrades(); ItemStack stack = new ItemStack(ItemInit.ARROW_STEEL.get(), 16); int villagerLevel = 1; trades.get(villagerLevel).add((trader, rand) -> new MerchantOffer( new ItemStack(Items.EMERALD, 2), stack,1,3,0.02F)); } if(event.getType() == VillagerProfession.TOOLSMITH) { System.out.println("\n\n### VillagerProfession.TOOLSMITH \n\n");//<----------- Int2ObjectMap<List<VillagerTrades.ItemListing>> trades = event.getTrades(); ItemStack stack = new ItemStack(ItemInit.INGOT_STEEL.get(), 1); int villagerLevel = 1; trades.get(villagerLevel).add((trader, rand) -> new MerchantOffer( new ItemStack(Items.EMERALD, 2), stack,10,8,0.02F)); } } //########## ########## ########## ########## the event is aknoledge and execute when the maps load  ### VillagerProfession.FLETCHER  ### VillagerProfession.TOOLSMITH  //########## But is not working      is a random piece of code is not working  could it be than this code is old 1.18 and no valid anymore for 1.20.4 or the thing are this numbers  stack,10,8,0.02F));  i dont know what this numbers means    ########## the question is ¿how to add things to the villager traders    thanks for your attention
