Can I create a block that when placed like a bookshelf around an enchantment table boosts the power like a bookshelf?

Override

getEnchantPowerBonus

in your Block.

 

I get the error

 

The method getEnchantPowerBonus() of type AmethystBlock must override or implement a supertype method

 

Full code:

 

package me.thatgamerblue.amethyst.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraft.item.ItemBlock;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.fml.common.registry.GameRegistry;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
import me.thatgamerblue.amethyst.creative.CreativeTab;

public class AmethystBlock extends Block{

public AmethystBlock() {
	super(Material.IRON); //no idea
	setUnlocalizedName("blockAmethyst");
	setRegistryName("blockAmethyst");
	setLightLevel(0.45f); //light level of 5-6
	setCreativeTab(CreativeTab.amethystCreativeTab);
	setHardness(5.0f); //iron block
	setResistance(10.0f); //iron block
	setHarvestLevel("pickaxe", 2); //iron pick or better
	GameRegistry.register(this);
	GameRegistry.register(new ItemBlock(this), getRegistryName());
}

@SideOnly(Side.CLIENT)
public void initModel() {
	ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(this), 0, new ModelResourceLocation(getRegistryName(), "inventory"));
}

@Override
public int getEnchantPowerBonus() {
	return 15;
}

}
