建立一個附魔書類

public class FireBoomEnchantment extends Enchantment {
    [...]
}

在類中添一下

@Override
    public int getMinimumPower(int level) {
        return 15;
    }

    @Override
    public int getMaximumLevel() {
        return 1;
    }

    @Override
    public void onTargetDamaged(LivingEntity user, Entity target, int level) {
        if(target instanceof LivingEntity) {
            World world = user.world;
            boolean bl = world.getGameRules().getBoolean(GameRules.MOB_GRIEFING);
            world.createExplosion(target, target.prevX, target.prevY, target.prevZ, 1.0f, bl, bl ? Explosion.DestructionType.DESTROY : Explosion.DestructionType.NONE);
            world.spawnEntity(target);
        }
    }

這就建立了一個FireBoom附魔書

onTargetDamaged //當目標被攻擊

在mc FireballEntity類有一個 方法就是當火球碰撞了就建立一個火焰爆炸的效果

protected void onCollision(HitResult hitResult) {
      super.onCollision(hitResult);
      if (!this.world.isClient) {
         if (hitResult.getType() == HitResult.Type.ENTITY) {
            Entity entity = ((EntityHitResult)hitResult).getEntity();
            entity.damage(DamageSource.explosiveProjectile(this, this.owner), 6.0F);
            this.dealDamage(this.owner, entity);
         }

         boolean bl = this.world.getGameRules().getBoolean(GameRules.MOB_GRIEFING);
         this.world.createExplosion((Entity)null, this.getX(), this.getY(), this.getZ(), (float)this.explosionPower, bl, bl ? Explosion.DestructionType.DESTROY : Explosion.DestructionType.NONE);
         this.remove();
      }

   }

咱們能夠加以利用

boolean bl = world.getGameRules().getBoolean(GameRules.MOB_GRIEFING);
    world.createExplosion(target, target.prevX, target.prevY, target.prevZ, 1.0f, bl, bl ? Explosion.DestructionType.DESTROY : 
    Explosion.DestructionType.NONE);

this.world.createExplosion()

咱們替換相對應的參數 參數一就是實體 target就是攻擊目標 參數2、3、四 就是目標 X Y Z 因爲 xyz是private 只能用 public 的 prevX prevY prevZ 參數五就是爆炸大小 參數六不用管
world.spawnEntity(target);//生成實體在target

建立附魔書

private static final FireBoomEnchantment END_FIRE_BOOM_ENCHANTMENT = new FireBoomEnchantment(
            Enchantment.Weight.VERY_RARE,
            EnchantmentTarget.WEAPON,
            new EquipmentSlot[] {
                    EquipmentSlot.MAINHAND
            }
    );

註冊

Registry.register(Registry.ENCHANTMENT,new Identifier("endarmor","end_fire_boom_enchantment"),END_FIRE_BOOM_ENCHANTMENT);
