作为一个游戏爱好者,我经常听到和玩到Minecraft。但作为一个程序员,我更想了解Java版Minecraft背后的代码实现。

在Java版Minecraft中,游戏内容是用Java编写的,并使用了许多Java库和框架。其中,最值得一提的是Minecraft Forge,它是一个功能强大的开源框架,允许开发者在Minecraft中添加定制化内容。

代码示例1:使用Minecraft Forge添加内置块


public class MyBlock extends Block {

  public MyBlock(Properties props) {

    super(props);

  }

  

  // myBlock有特殊难度(等级)和阻挡耐久度,它不能被物品推动,只能被爆炸破坏

  @Override

  public boolean canEntityDestroy(BlockState state, IBlockReader world, BlockPos pos, Entity entity)

    return false;

  

  @Override

  public float getBlockHardness(BlockState state, IBlockReader worldIn, BlockPos pos)

    return 10.0f;

  

  

  @Override

  public PushReaction getPushReaction(BlockState state)

    return PushReaction.DESTROY;

  

}

代码示例2:使用Minecraft Forge添加物品,例如食物


public class MyFoodItem extends Item {

  public MyFoodItem(Properties props) {

    super(props);

  }

  

  // everything related to consuming the food item

  @Override

  public ItemStack onItemUseFinish(ItemStack stack, World worldIn, LivingEntity livingEntityIn) {

    if (livingEntityIn instanceof PlayerEntity) {

      // give the player some health when eating the food item

      PlayerEntity playerEntity = (PlayerEntity) livingEntityIn;

      playerEntity.heal(2.0f);

    }

    return super.onItemUseFinish(stack, worldIn, livingEntityIn);

  }

  // sets how much health it restores

  @Override

  public int getHealAmount(ItemStack stack)

    return 5;

  

  // sets how long it takes (in ticks) before the player can eat again

  @Override

  public int getUseDuration(ItemStack stack)

    return 20;

  

}

代码示例3:使用Minecraft Forge添加实体,例如怪物


public class MyMonsterEntity extends MobEntity {

  private static final EntitySize SIZE = EntitySize.fixed(0.6f, 1.95f);

  public MyMonsterEntity(EntityType type, World world) {

    super(type, world);

  }

  @Override

  protected void registerGoals() {

    // add custom AI goals

    this.goalSelector.addGoal(0, new SwimGoal(this));

    this.goalSelector.addGoal(1, new LeapAtTargetGoal(this, 0.4f));

    this.goalSelector.addGoal(2, new MeleeAttackGoal(this, 1.0f, false));

  }

  @Override

  public ItemStack getPickedResult(RayTraceResult target) {

   // get the item form of our mob

   return new ItemStack(MyMonsterSpawnEgg.ITEM);

  }

  @Override

  public EntitySize getSize(Pose poseIn)

    return SIZE;

  

}

通过以上示例,我们可以看到Java版Minecraft的代码非常富有扩展性,开发者可以通过添加物品、块、实体等来自定义游戏内容。最终实现了一个“随心所欲”的游戏世界。
