CBUltimate

I would assume placing lava with bucket can be canceled in BlockEvent.PlaceEvent, but it doesn't, so how can cancel players placing down lava? Thanks in advance.

I'm sorry if this may sound stupid but If I remove static, my ModEventHandler class can't access it. From there on I'm not sure what to do. I've renamed my mod to mod.cbultimate. Thanks for the tip, my unlocalized names includes ModID now. Thanks for that too.

Sorry, but I got it working. I just had to markDirty(). It works perfectly now. I'm just making this for my learning so com.cbultimate is just my name and .com. Domain name's not taken.

I'm starting to understand how WorldSavedData works, but when reload the game it doesn't load any data.

How to make a ArrayList of block position on the server side and save it so it can be loaded the next time the server reopens?

I want to use BlockEvent.PlaceEvent to check if it is within the block(Authentication Block)'s protecting region 16x16x16 and whenever a player place a block, the Authentication block checks if the player's name is in the Arraylist of the block's Tile Entity, if yes, allow player to place. If not, cancel the player's Place event and display a message to them that it's a protected area. I want to know how can my BlockEvent.PlaceEvent check if player is placing a block within the Authentication Block's region. Thanks for helping.

I've made a block which can be authorized by players.How should I make that when it's authorized, they should be allow to place blocks in a 16x16x16 radius of the block?

I'm stuck working with TileEntity, I still don't quite understand what's wrong, boolean pass keeps returning false and doesn't get to executeAuthorization(). Please help, thanks in advance.

I've added createTileEntity in the block class and made a new class for the tile entity which I've already registered, but I'm not sure how should I use it for storing my arrays of authorized players. :'( - hasTileEntity is deprecated. @Nullable @Override public TileEntity createTileEntity(World world, IBlockState state) { return new TileEntityToolCupboard(); } public ArrayList<String> Authorized = new ArrayList<String>(); @Override public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing heldItem, float side, float hitX, float hitY) { if (worldIn.isRemote) { return true; } else { boolean isClaimed = false; for (int c = 0; c < Authorized.size(); c++) { if (playerIn.getName().equals(Authorized.get(c))) { isClaimed = true; Authorized.remove(c); playerIn.addChatMessage(new TextComponentString("You have been de-authorized by this tool cupboard.")); break; } } if (!isClaimed) { playerIn.addChatMessage(new TextComponentString("You have been authorized by this tool cupboard.")); Authorized.add(playerIn.getName()); playerIn.addChatMessage(new TextComponentString(Authorized.toString())); } return true; } } package com.cbultimate.stranded.tileentity; import net.minecraft.tileentity.TileEntity; public class TileEntityToolCupboard extends TileEntity { }

Since I have hardness and resistance set on the block, how should I change it into TileEntity while keeping those settings?

So far I've made it when I right click the block, a player's name will be on the block's ArrayList, problem is it's not independent. If I have two blocks, the would both have the same list. How can I separate them and step do I take next to protect the 16x16x16 around the block. Thanks in advance!

How should I make a block to function as a region build protector? I want to make a block when placed, will protect a 16x16x16 region in the world. So far I've only looked up how to cancel BlockEvent.PlaceEvent but I don't know what else I need to learn to piece them together. This could be a bit much so thanks in advance for any small bits of information.

Hi, I'm pretty new to modding and I would like to know how to modify the hardness and resistance of a vanilla wooden door? Thanks in advance~

Why does it only smelt 1 Iron Ingot when I set the amount to 2? GameRegistry.addSmelting(new ItemStack(Items.IRON_INGOT, 2), new ItemStack(ModItems.reinforcedIronBar), 1.0F);

Thanks, item.ingotIron.name=Iron Bar worked well. I'd like to ask where can I get the list of all items?

Thanks, but it didn't work.

Hi, I'm very new to modding and I want to know if it is possible to rename the vanilla Iron Ingot into Iron Bar and make that if you smelt Iron Ingot it will become Reinforced Iron Bar (which I've already made). Thanks in advance!
