I just started learning how to mod and I am very confused. My mod is simply adding platinum to the game as a hello world type of project. I am learning about block properties and I think that my platinum block should be able to be the base of a beacon. I have seen many things on the internet but they don't seem to work. Can someone please help me by showing me what I should insert into my code and what it means so I can learn from this. I would be very appreciative of your time and work. Below is my code for my specific Platinum Block class:

package com.Melon9191.PlatinumMod.blocks;

import net.minecraft.block.SoundType;
import net.minecraft.block.material.Material;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.world.World;
import net.minecraft.block.*;

public class PlatinumBlock extends BlockBase 
{
	
	public PlatinumBlock(String name, Material material) 
	{
		super(name, material);
		
		setCreativeTab(CreativeTabs.BUILDING_BLOCKS);
		setSoundType(SoundType.METAL);
		setHardness(5.5F);
		setResistance(30.0F);
		setHarvestLevel("pickaxe", 2);
		
	}
}

Thank you for whatever answers you can give me!

I'm afraid you're using an unsupported version of Minecraft, it would be best to update to 1.14 or 1.15 in order to receive support.
