I'm trying to make a lectern so players can place a book in it and open its GUI when right click the block. But unfortunately the GUI doesn't show up when the player right click the block. This is the block code i'm using

package com.mineworld.blocks.decorations;

public class BlockLectern extends BlockHorizontal implements ITileEntityProvider {

public BlockLectern() {
	super(Material.WOOD);
	this.setHardness(2.0F);
	this.setSoundType(SoundType.WOOD);
	this.setCreativeTab(MWTabs.tabDecorations);
	this.setDefaultState(this.blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH));
}

public IBlockState withRotation(IBlockState state, Rotation rot) {
	return state.withProperty(FACING, rot.rotate((EnumFacing) state.getValue(FACING)));
}

	return state.withRotation(mirrorIn.toRotation((EnumFacing) state.getValue(FACING)));
}

/**

 * allow for adjustments to the IBlockstate
 */
public IBlockState onBlockPlaced(World worldIn, BlockPos pos, EnumFacing facing, float hitX, float hitY, float hitZ,
		int meta, EntityLivingBase placer) {
	return this.getDefaultState().withProperty(FACING, placer.getHorizontalFacing());
}

}

	return new BlockStateContainer(this, new IProperty[] { FACING });
}

@Override
public boolean isOpaqueCube(IBlockState state) {
	return false;
}

@Override
public boolean isFullCube(IBlockState state) {
	return false;
}

@Override
public TileEntity createNewTileEntity(World worldIn, int meta) {
	return new TileEntityLectern();
}

@Override
public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn,
		EnumHand hand, ItemStack heldItem, EnumFacing side, float hitX, float hitY, float hitZ) {
	if (!worldIn.isRemote) {
		TileEntity te = worldIn.getTileEntity(pos);
		if (te instanceof TileEntityLectern) {
			TileEntityLectern wr = (TileEntityLectern) te;
			if (heldItem != null && heldItem.getItem() != null && heldItem.getItem() instanceof ItemWrittenBook) {
				if (wr.addItem(heldItem)) {
					playerIn.inventory.removeStackFromSlot(playerIn.inventory.currentItem);
					return true;
				}
			}
			if(playerIn.isSneaking())
				wr.removeItem();
			else {
				if(wr.item != null) {
					playerIn.openBook(wr.item, hand);
				}
			}

		}
	}
	return true;
}

public void breakBlock(World worldIn, BlockPos pos, IBlockState state) {
	TileEntity tileentity = worldIn.getTileEntity(pos);

	if (tileentity instanceof TileEntityLectern) {
		((TileEntityLectern) tileentity).removeItem();
	}

	super.breakBlock(worldIn, pos, state);
}

}

 

I'm sure the book is correctly saved into the tile entity because i can remove the book from the block if i shift-click it. So why the GUI doesn't open? :/

Don't blame me if i always ask for your help. I just want to learn to be better :)

By the way you don't need both of these checks:

heldItem != null && heldItem.getItem() != null

The first one is sufficient, you will never have a non-null item stack of a null item.

 

Also, don't use ITileentityProvider, you should override the hasTileEntity and getTileEntity methods that are present in the Block class (which have a different signature).

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

Wops, ok so now the block class extends blocks and uses the Block.class methods for the tile entity

}

 

But the behavior is not changed, i can still put a book in it, get it back if i shift click but if i right click it won't open the book gui of the book stored in it (wich i assume is correctly stored since i can get it back) :/

Don't blame me if i always ask for your help. I just want to learn to be better :)

The ITileEntityProvider thing was not actually related to your problem, it was getting your class to use the more up to date method of having a TE.

 

My only suggestion is to use your debugger to step through your code and see what is not being called and why.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

So debugging looks like client side the game check if the book is a writable book (not a written one) and so the GUI doesn't show up. By adding this

Minecraft.getMinecraft().displayGuiScreen(new GuiScreenBook(playerIn, wr.item, false));

to the block code i can now show the GUI. But i'm confused on why the client check for a writable book if that code is called from the ItemWrittenBook :/

Don't blame me if i always ask for your help. I just want to learn to be better :)
