Kloonder

Ok, it returns true now, well thats good, thanks, but that doesn't fix that my entity wont get rendered

I had the problem once to, then I wrote a my klooncore, and that works perfectly, just look at my source: https://github.com/KloonTV/Forge-Modding/tree/master/java/de/kloon/klooncore I have the bad feeling you will just copy and paste So my source is not made for copy and paste, and most of the stuff like KloonsCustomRecipeHandler is bad programmed any, but it works

Because it doen't matter where I spawn the entity, it will teleported to the position where the player is looking anyway, I can change the values to, player.posX, player.posY, player.posZ

But here is the most weird thing: @Override public void onUpdate(ItemStack stack, World world, Entity player, int itemSlot, boolean isSelected) { EntityArrow arrow = new EntityArrow(world, player.posX, player.posY, player.posZ); world.spawnEntityInWorld(arrow); if(!world.isRemote){ WorldServer server = (WorldServer) world; System.out.println(server.getEntityFromUuid(arrow.getPersistentID()) == arrow); } arrow.setDead(); Works perfectly public void takeBlock(World world, EntityPlayer player, BlockPos pos, float hitX, float hitY, float hitZ, int id){ ItemStack stack = player.getCurrentEquippedItem(); stack.setTagCompound(new NBTTagCompound()); NBTTagCompound nbt = stack.getTagCompound(); EntityNotFallingBlock nfb = new EntityNotFallingBlock(world, hitX, hitY, hitZ, world.getBlockState(pos)); // nfb.theBlock = world.getBlockState(pos); world.spawnEntityInWorld(nfb); // nbt.setString("EntityID", nfb.getPersistentID().toString()); WorldServer server = (WorldServer) world; System.out.println(server.getEntityFromUuid(nfb.getPersistentID()) == nfb); Doesn't work

I just hope for you to help me, because I'm stuck: Sometimes this code works, sometimes not: public void takeBlock(World world, EntityPlayer player, BlockPos pos, float hitX, float hitY, float hitZ, int id){ ItemStack stack = player.getCurrentEquippedItem(); stack.setTagCompound(new NBTTagCompound()); NBTTagCompound nbt = stack.getTagCompound(); EntityNotFallingBlock nfb = new EntityNotFallingBlock(world, hitX, hitY, hitZ, world.getBlockState(pos)); nfb.theBlock = world.getBlockState(pos); world.spawnEntityInWorld(nfb); nbt.setString("EntityID", nfb.getPersistentID().toString()); WorldServer server = (WorldServer) world; System.out.println(server.getEntityFromUuid(UUID.fromString(nbt.getString("EntityID"))) == nfb); Thats the main problem right now

It's the vanilla code dude, the not Falling Block is just not really hard to read, and the renderer is a complete copy of vanilla code, so... and if you mean my Item code, look a bit closer, it is explained

EntityRegistry.registerModEntity(EntityNotFallingBlock.class, modid + "EntityNOTFallingBlock", 0, this, 64, 20, true); No properly? The rest of the problem is in my Entity then, because it nearly never shows, and when for like 0.1 second, so it could be a problem in the class itself, or in the render, but the rendere is an exact copy of the vanilla renderer, exactly as the entity...

So with the code above, it should spawn?

Hm thats a good question, I wont to have the entity also on server, so that other players can see it, but the problem is the entity is only added on server, so I have to extra add it it on the client, or is there a better way to do this? @Override public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ) { NBTTagCompound nbt = stack.getTagCompound(); Entity entity = null; if(!world.isRemote){ WorldServer serverWorld = (WorldServer) world; try{ if(nbt.getString("EntityID") != ""){ entity = serverWorld.getEntityFromUuid(UUID.fromString(nbt.getString("EntityID"))); } }catch(Exception e){ } if(entity == null){ takeBlock(world, player, pos, hitX, hitY, hitZ, 3); }else{ placeBlock(world, stack); } }else{ } return true; } public void takeBlock(World world, EntityPlayer player, BlockPos pos, float hitX, float hitY, float hitZ, int id){ ItemStack stack = player.getCurrentEquippedItem(); stack.setTagCompound(new NBTTagCompound()); NBTTagCompound nbt = stack.getTagCompound(); EntityNotFallingBlock nfb = new EntityNotFallingBlock(world, hitX, hitY, hitZ, world.getBlockState(pos)); nfb.theBlock = world.getBlockState(pos); nbt.setString("EntityID", nfb.getPersistentID().toString()); world.spawnEntityInWorld(nfb); WorldServer server = (WorldServer) world; //Check if Block is chest or something like that if(world.getBlockState(pos).getBlock().hasTileEntity(world.getBlockState(pos))){ TileEntity tile = world.getTileEntity(pos); NBTTagCompound tileData = new NBTTagCompound(); tile.writeToNBT(tileData); nbt.setTag("NBTBlock", tileData); nfb.tileEntityData = tileData; } //Sets some stuff to nbt item, so It knows what Id block has nbt.setInteger("ID", Block.getIdFromBlock(world.getBlockState(pos).getBlock())); nbt.setBoolean("IsBlock", true); nbt.setInteger("EntityIDC", nfb.getEntityId()); //Just copy of vanilla code, to save things like diorite Block block = nfb.fallTile != null ? nfb.fallTile.getBlock() : Blocks.air; ResourceLocation resourcelocation = (ResourceLocation)Block.blockRegistry.getNameForObject(block); nbt.setString("Block", resourcelocation == null ? "" : resourcelocation.toString()); nbt.setByte("Data", (byte)block.getMetaFromState(nfb.fallTile)); if (nfb.tileEntityData != null) { nbt.setTag("TileEntityData", nfb.tileEntityData); } // entity = nfb; //makes block disapear world.setBlockToAir(pos); Thats the code to add the entity and take the block, but it gets only called on the server, any better way to do this?

So I removed that field now, It works just perfect on Server, but now I have to problem, becuase how should I get the Entity, that is only on Client

has some problems, I tried this public void takeBlock(World world, EntityPlayer player, BlockPos pos, float hitX, float hitY, float hitZ, int id){ ItemStack stack = player.getCurrentEquippedItem(); stack.setTagCompound(new NBTTagCompound()); NBTTagCompound nbt = stack.getTagCompound(); EntityNotFallingBlock nfb = new EntityNotFallingBlock(world, hitX, hitY, hitZ, world.getBlockState(pos)); nfb.theBlock = world.getBlockState(pos); nbt.setString("EntityID", nfb.getPersistentID().toString()); world.spawnEntityInWorld(nfb); WorldServer server = (WorldServer) world; System.out.println(server.getEntityFromUuid(UUID.fromString(nbt.getString("EntityID"))) == nfb); That return true, which is good, but this: Entity entity; //this is used to get the entity, which should replaces the Entity entity above, but it doesn't work on both client and server if(!world.isRemote){ WorldServer serverWorld = (WorldServer) world; entity = serverWorld.getEntityFromUuid(UUID.fromString(nbt.getString("EntityID"))); System.out.println(entity); }else{ entity = findTheCorrectEntity(world, UUID.fromString(nbt.getString("EntityID"))); } It says the entity is null

Hm, I can find only world.getEntityByID(id), you may mix it up with world.getPlayerEntityByUUID(uuid)

so .equals() i guess

It draws a block, exactly like a falling sand, so you can see where you place your block, its necessary

Ok ok, I will explain you: My iteem can take up Blocks, and put them back on the ground again Used to check if it should place or take the block @Override public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ) { if(!world.isRemote){ if(entity == null){ takeBlock(world, player, pos, hitX, hitY, hitZ, 3); }else{ placeBlock(world, stack); } }else{ } return true; } Used to take Blocks public void takeBlock(World world, EntityPlayer player, BlockPos pos, float hitX, float hitY, float hitZ, int id){ EntityNotFallingBlock nfb = new EntityNotFallingBlock(world, hitX, hitY, hitZ, world.getBlockState(pos)); nfb.theBlock = world.getBlockState(pos); world.spawnEntityInWorld(nfb); ItemStack stack = player.getCurrentEquippedItem(); NBTTagCompound nbt = stack.getTagCompound(); //Check if Block is chest or something like that if(world.getBlockState(pos).getBlock().hasTileEntity(world.getBlockState(pos))){ TileEntity tile = world.getTileEntity(pos); NBTTagCompound tileData = new NBTTagCompound(); tile.writeToNBT(tileData); nbt.setTag("NBTBlock", tileData); nfb.tileEntityData = tileData; } //Sets some stuff to nbt item, so It knows what Id block has nbt.setInteger("ID", Block.getIdFromBlock(world.getBlockState(pos).getBlock())); nbt.setBoolean("IsBlock", true); nbt.setString("EntityIDClient", nfb.getUniqueID().toString()); nbt.setInteger("EntityIDServer", nfb.getEntityId()); //Just copy of vanilla code, to save things like diorite Block block = nfb.fallTile != null ? nfb.fallTile.getBlock() : Blocks.air; ResourceLocation resourcelocation = (ResourceLocation)Block.blockRegistry.getNameForObject(block); nbt.setString("Block", resourcelocation == null ?

It was just a rondom number, to show you you can register from 0 - nearly infinite. Just wanted to help Sir Perfect

GameRegistry.registerTileEntity(MyTileEntity.class, 15); You could maybe try this

EntityArrow arrow = new EntityArrow(world); world.spawnEntityInWorld(arrow); System.out.println(world.getEntityByID(arrow.getEntityId()) == arrow); you said it should work just fine, but I put this code into my update method, but it return null as I said

It onlz semms to work on client, so how on server?

So I have a problem, becuase I'm trying to save my entity reference to my Item NBT, so I can move my Entity with my Item, but I think that code says everything: EntityArrow arrow = new EntityArrow(world); world.spawnEntityInWorld(arrow); System.out.println(world.getEntityByID(arrow.getEntityId()) == arrow); It returns false

So I am here in my Item Class: Entity entity; @Override public boolean onItemUse(ItemStack stack, EntityPlayer player, World world, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ) { if(entity == null){ System.out.println(FMLCommonHandler.instance().getEffectiveSide() + "Take"); takeBlock(world, pos, hitX, hitY, hitZ, 3); }else{ if(entity instanceof EntityNotFallingBlock){ System.out.println(FMLCommonHandler.instance().getEffectiveSide() + "Place"); world.setBlockState(new BlockPos(entity), ((EntityNotFallingBlock) entity).theBlock); entity.setDead(); entity = null; } } return true; } @Override public void onUpdate(ItemStack stack, World world, Entity player, int itemSlot, boolean isSelected) { // if(blockPlaced){ // entity = null; // blockPlaced = false; // } if(!stack.hasTagCompound()){ stack.setTagCompound(new NBTTagCompound()); } NBTTagCompound nbt = stack.getTagCompound(); if(player instanceof EntityPlayer){ if(((EntityPlayer) player).getCurrentEquippedItem() == stack){ if(entity != null){ boolean flag = true; if(entity instanceof EntityNotFallingBlock){ if(((EntityNotFallingBlock) entity).getAllowFall()){ flag = false; } } if(flag){ int far = 5; if(player.rayTrace(far, 1) != null){ if(player.rayTrace(far, 1).hitVec != null){ MovingObjectPosition mop = player.rayTrace(far, 1); Vec3 hit = mop.hitVec; int side = mop.sideHit.getIndex(); switch(side){ case 0: entity.setPositionAndUpdate((int)hit.xCoord + 0.5, (int)hit.yCoord - 1, (int)hit.zCoord - 0.5); break; case 1: entity.setPositionAndUpdate((int)hit.xCoord + 0.5, (int)hit.yCoord, (int)hit.zCoord - 0.5); break; case 2: entity.setPositionAndUpdate((int)hit.xCoord + 0.5, (int)hit.yCoord, (int)hit.zCoord - 0.5); break; case 3: entity.setPositionAndUpdate((int)hit.xCoord + 0.5, (int)hit.yCoord, (int)hit.zCoord + 0.5); break; case 4: entity.setPositionAndUpdate((int)hit.xCoord - 0.5, (int)hit.yCoord, (int)hit.zCoord - 0.5); break; case 5: entity.setPositionAndUpdate((int)hit.xCoord + 0.5, (int)hit.yCoord, (int)hit.zCoord - 0.5); break; } } } } } } } } I know the Entity entity is not the best solution, if this is the problem I'm sorry, but the problem is, when I use my item on a block, it takes it on client(or the other way around), and places it on server, if I delete the code which should place the block, it works, but thats not a solution Should I try with network, but I mean the onItemUsed is called the exact same way on both server and client, so it makes no sense to me
