我的世界-探测玩家背包物品的方法
　　我的世界里面对于命令方块的使用是游戏一大难点之一，很多时候命令方块可以简化玩家的建造流程，不过对玩家的代码知识要求比较高，下面是命令方块实现探测玩家背包的方法。
　　探测玩家背包物品的方法
　　教大家如何在MC1.8里探测玩家背包的物品。
　　有2个做法：一个是用/clear，另一个是用/testfor。用testfor做更加高级，不过1.8更新后/clear也可以探测NBT什么，所以2个方法都可以。这个东西可以放在冒险地图里面。
　　首先是clear。自从1.8更新后，clear的格式改变了。现在可以自定义清空数量和物品NBT了。现在的指令格式：
　　/clear &玩家& &物品& [数据] [数量] [dataTag]
　　/clear我就不详细多说了，这条指令在很早就有了，不过以前一直没法清空自定义数量，自定义NBT等。给大家举个例子：如果要清空玩家背包里的一个叫“Test”的石剑：
　　那么指令就是：
　　clear @a minecraft:stone_sword 0 1 {display:{Name:"Test"}}
　　大家看见，指令里的1就是数量，后面的{display:{Name:"Test"}}意思就是石剑的NBT，也就是拥有自定义名字为“Test”的石剑。所以，当大家按下按钮后，如果背包里没有叫Test的石剑，那就是指令无效，不会给出输出。有的话就会情空掉一个石剑，然后给出输出。如果是要单纯物品探测的话，那请自行把数量改成0，然后后面用比较器进行输出。/clear比较基础我就不多深入讲解了。
　　之后就是/testfor指令了。1.8又更新了点NBT，让/testfor更强大了。用testfor的好处就是可以自定义物品栏等等，还可以探测玩家已经选中的物品栏。指令：
　　/testfor @p {Inventory:[{Slot:0b,id:minecraft:stone_sword,Damage:0s,Count:1b,tag:{display:{Name:"Test"}}}]}
　　大家看见，这条指令还是探测刚才的一个叫“Test”的石剑。不过这次更加高级。NBT讲解：
　　Inventory：探测玩家仓库背包。/testfor用的，如果要探测玩家背包一定要加入这个NBT。
　　Slot：玩家物品的槽位。这行可选可不选。帖子下面会详细讲解槽位，单位是b。(数字后面一定要打b，比如：1b，0b等等)
　　id：探测目标物品的id。本人这里打的是minecraft:stone_sword，也就是石剑的ID。大家自行修改。
　　Damage：数据。这行默认为0，数据用来分辨多个相同物品。比如：多彩色的羊毛。单位是s，一定要加。
　　Count：数量。单位是b，一定要加入。这个好像只对可叠加物品起效，比如有5个叠加的羊毛，就可以探测得到。5把石剑的话，如果不是叠加在一起，那就无发探测，导致输出失败。
　　tag：这个我就不多说了，基础的NBT链接NBT。这个很多指令都可以用：summon，setblock等等。后面括号里的就是另外的NBT，控制石剑本身，而不和/testfor搞混。
　　(本教程不会加入探测玩家选中槽位教程。上次已经发过一个了(SelectedItemSlot)，有兴趣的点击这里查看)
　　之后来说下背包槽位。大家知道，当打开背包后有很多很多槽位可以放物品。而/testfor探测背包有一项是可以探测玩家放入物品的槽位的。这个最大的用处就是可以探测玩家穿着什么装备什么。槽位的控制图：
　　大家看见，0就是玩家选中的第一个槽位。之后100就是鞋子，101就是裤子，到103就是头盔。合成物品的是80，81，82和83。其他就不多说了，大家可以自己研究。玩家选中的槽位就是0-8。
　　Slot讲解。大家看见指令里的是0b，也就是玩家第一个手拿的物品。(详情看玩家背包槽位分布图)。所以，Slot后面填写的就是0b-8b，这个探测不一定要是玩家选中了这个槽位，而是只要这个槽位里有达到要求的物品就可以了。配合SelectedItemSlot的话可以达到更好的效果。

& 《我的世界》可以说红遍全球，它没有华丽的画面，没有什么游戏特效，但是它最大的优势就是在于它的游戏性，玩家在一个完全开放的世界，可以完全按照自己的想法建造，最近玩家通过NBT实现了自定义背包物品，到底怎样操作指令又如何使用呢，下面看看详细的我的世界自定义背包物品教程吧。
& 这个也不光是指令方块，可以在刷怪笼上运行，目的是可以放置一个刷钻石套装僵尸的刷怪笼。这个是使用了1.8的新NBT：BlockEntityTag。指令例子：
& /give @p minecraft:command_block 1 0
& {BlockEntityTag:{Command:&/setblock ~ ~1 ~ minecraft:gold_block 0 replace&}}
& 注意：版本要最起码14w07a。以上指令的意思就是给玩家一个指令方块。但是当玩家放置了这个指令方块后，里面就已经拥有自定义指令了，这条自定义指令就是：/setblock ~ ~1 ~ minecraft:gold_block 0 replace 。BlockEntityTag的意思就是把在玩家物品栏里的物品自定义。之后不光是指令方块，可以用在刷怪笼上面。指令例子：
& /give @p minecraft:mob_spawner 1 0
& {BlockEntityTag:{EntityId:Zombie,SpawnData:{ActiveEffects:[{Id:1,Amplifier:4,Duration:9999999},
& {Id:5,Amplifier:9999999,Duration:9999999},
& {Id:10,Amplifier:9999999,Duration:9999999},
& {Id:11,Amplifier:9999999,Duration:9999999},
& {Id:12,Amplifier:9999999,Duration:9999999},
& {Id:13,Amplifier:9999999,Duration:9999999}],
& Equipment:[{id:276,Count:1,tag:{ench:[{id:16,lvl:},{id:19,lvl:},{id:20,lvl:},{id:17,lvl:},{id:18,lvl:},{id:34,lvl:}]}},
& {id:313,Count:1,tag:{ench:[{id:0,lvl:},{id:1,lvl:},{id:2,lvl:},{id:3,lvl:},{id:4,lvl:},{id:7,lvl:},{id:34,lvl:}]}},
& {id:312,Count:1,tag:{ench:[{id:0,lvl:},{id:3,lvl:},{id:1,lvl:},{id:4,lvl:},{id:7,lvl:},{id:34,lvl:}]}},
& {id:311,Count:1,tag:{ench:[{id:0,lvl:},{id:3,lvl:},{id:1,lvl:},{id:4,lvl:},{id:7,lvl:},{id:34,lvl:}]}},
& {id:52,Count:1,AttributeModifiers:[{Operation:0,UUIDLeast:1,UUIDMost:1,Amount:950.0,AttributeName:generic.attackDamage,Name:Attack_Cage},
& {Operation:0,UUIDLeast:2,UUIDMost:2,Amount:950.0,AttributeName:generic.knockbackResistance,Name:Knockback_Cage},
& {Operation:0,UUIDLeast:4,UUIDMost:4,Amount:990.0,AttributeName:generic.maxHealth,Name:Health_Cage}]}],
& Attributes:[{Name:generic.attackDamage,Base:1000},
& {Name:generic.followRange,Base:250},
& {Name:generic.knockbackResistance,Base:700}
& {Name:generic.movementSpeed,Base:0.7},
& {Name:generic.maxHealth,Base:1000}],
& CustomName:&PotatoMaster101&,CustomNameVisible:1},
& SpawnCount:2,SpawnRange:6,RequiredPlayerRange:128,Delay:10,MinSpawnDelay:10,MaxSpawnDelay:100,MaxNearbyEntities:20}}
& 这条指令会给玩家一个普通的刷怪笼。但是玩家一旦放下，就会发现这个刷怪笼里的是钻石套装的无敌僵尸。于是玩家可以自己自定义方块，然后给方块自定义NBT，运用这个BlockEntityTag。

老师对小明说：“乳就是小的意思，比如乳猪就是小猪，请你用乳字造个句。” 小明：“我家很穷，只能住40平米的乳房！” 老师晕：“这个不行，换一个” 小明：“我每天上学，都要跳过我家门口的一条乳沟。” 老师狂晕：“不行，再换一个！” 小明：“老师，我想不出来了，把我的乳头都想破了！”

一朋友是酒鬼，后来找了女票就嚷嚷着戒酒了，说女票不喜欢酒鬼。两个月后去女票家吃饭，女票老爸叫陪他喝几口，结果控制不住喝高了，搂着女票老爸的肩喊着：兄弟咱再喝两杯！后来女票就跟他分了，分了……
又到了每日囧图吐槽时间！今天晒账单，几十万，几百万的朋友，我都标记了，日后有什么难处，大家都是朋友，多照顾一下。以前都不知道你们这么有钱，有时侯我态度不好是我的不对，从现在开始我们重新认识一下，以后你就是我的好兄弟。
又到了每日囧图吐槽时间！据统计，情侣在冬天选择分手的比例要远远大于在夏天。有人说这是因为人们在冬天更懒惰，更脆弱，更没耐心，更喜欢逃避。其实真实原因是，冬天衣服太贵，节日太多，太特么费钱了！

In real life, obsidian is an extrusive igneous rock like , meaning that they are both formed from lava that has cooled down.
Destroying an obsidian block with a diamond pickaxe while underwater without standing on solid ground would take 3 minutes and 54 seconds. (Without the pickaxe, it takes 4 minutes and 10 seconds.) Either way, the player will run out of air long before the block is mined. (Unless a potion of water breathing is used)
It is a common misconception that enough TNT will destroy obsidian. Even though its explosion resistance rating is finite, additional TNT or other explosives will have no more effect on an individual block than only one (it would take 71.25 times the explosive power of TNT to destroy a block of obsidian). It is possible to hack or use / an explosion strong enough to destroy obsidian, but no such explosion appears naturally.
