Hi, I am kind of new in Minecraft modding. I was following a video on how to create a custom Axe and shield for minecraft 1.12. It worked great. But when I realized the latest version of minecraft is 1.15, it seems like the code in 1.12 is completely broken in 1.15. And there isn't a good documentation 

 

Below is the code that is working in 1.12, but not in 1.15

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.projectile.EntityLargeFireball;
import net.minecraft.item.ItemAxe;
import net.minecraft.item.ItemStack;
import net.minecraft.util.ActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.world.World;

public class CustomAxe extends ItemAxe {

	public int power = 3;
	public String axeName = "my_axe";



	public CustomAxe(ToolMaterial material) {
		super(material, 1, 1);

		this.setUnlocalizedName(axeName);
		this.setRegistryName(axeName);
		this.setCreativeTab(CreativeTabs.COMBAT);
		this.setMaxDamage(power);
	}

	@Override
	public ActionResult<ItemStack> onItemRightClick(World world, EntityPlayer player, EnumHand hand) {
		if(!world.isRemote) {
			world.spawnEntity(createFireball(world, player, power));
		}

		return super.onItemRightClick(world, player, hand);
	}

	public static EntityLargeFireball createFireball(World world, EntityPlayer player, int power){
		EntityLargeFireball fireball =new EntityLargeFireball(world,player.posX,player.posY+2,player.posZ, player.getLookVec().x,player.getLookVec().y,player.getLookVec().z);
		fireball.explosionPower = power;
		fireball.shootingEntity = player;
		fireball.rotationPitch = player.rotationPitch;
		fireball.rotationYaw = player.rotationYaw;
		return fireball;
	}
}

 

Any idea how to convert above 1.12 code to 1.15?

Any 1.15 guide / documentation / tutorial?

I would try to make it work for 1.15.1 or .2, and also make sure your code is a working github repository. This will make it so if someone wants, they can clone your repository and build it themselves to help debug it if they have the time and/or inclination.

Then link to it here with errors you get that you cannot figure out, and post logs if it runs but crashes.

 

I did find the link that describes many of the changes that came after 1.12, so it may help.

I think I got it. This is how I create custom Axe which spit fireball in 1.15

package com.ayclogic.aycfirstmod.item;

import com.ayclogic.aycfirstmod.init.ModItemGroup;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.entity.projectile.FireballEntity;
import net.minecraft.item.*;
import net.minecraft.util.ActionResult;
import net.minecraft.util.Hand;
import net.minecraft.world.World;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class AycAxe extends AxeItem {
    public static final Logger LOGGER = LogManager.getLogger(AycAxe.class);
    public int fireballStrength = 3;
    public AycAxe() {
        super(ItemTier.IRON, 6.0F, -3.1F, new Item.Properties().group(ModItemGroup.MOD_ITEM_GROUP));
    }
    public AycAxe(IItemTier tier, float attackDamageIn, float attackSpeedIn, Item.Properties builder) {
        super(tier, attackDamageIn, attackSpeedIn, builder);
    }

    public ActionResult<ItemStack> onItemRightClick(World world, PlayerEntity player, Hand handIn) {

        FireballEntity fireballentity = new FireballEntity(world, player,player.getLookVec().x,player.getLookVec().y,player.getLookVec().z);
        fireballentity.explosionPower = fireballStrength;
        fireballentity.rotationPitch = player.rotationPitch;
        fireballentity.rotationYaw = player.rotationYaw;
        fireballentity.setPosition(player.getPosX(), player.getPosY()+2, player.getPosZ());
        world.addEntity(fireballentity);

        LOGGER.info("********** Magic Axe swing **************");
        return super.onItemRightClick(world, player, handIn);
    }
}
