技能道具范例
前言
在 MC 中，所谓的技能，实际上只不过也是一个道具，通过某种方式触发（如按Q丢弃触发、F副手触发等）相应的事件达到想要的效果，就是我们平常所看到的“技能”效果。
这类系统一般分为三个部分。
- 检测道具（技能）是否被触发，
- 触发相应的事件，
- 技能冷却和再补给。
我们将通过一个实例来讲解这三部分内容的组成。其中如果有错误，还请读者指正。
例如，在一个只有红队和蓝队PVP的小游戏中，我们希望通过F键触发一个技能，这个技能可以让我们瞬移到敌方一名玩家背后，同时触发1秒钟的力量加成效果。
所涉及到的记分板:
- 名称: 技能1的冷却时间
- Objective: skill1CD
- Criteria: dummy`
本教程的命令都会放在一个高频里循环运行。
道具触发
就像上面说的那样，首先我们要检测道具的触发，那么我们先设定这样一个道具。我们使用染料作为技能图标，其带有一个{AssSkill:1}的标签（自定义NBT），以便我们检测。
当检测到副手的位置有这个技能的时候，视为触发。（F键为切换当前物品到副手）
副手Slot为-106
scoreboard players tag @a[m=2] add skillSpell1 {Inventory:[{Slot:-106b,id:"minecraft:dye",Count:1b,Damage:5s,tag:{AssSkill:1}}]}
从这里我们可以看到检测副手位的方法就是检测玩家的Inventory中-106b这个Slot，如果这个位置有技能道具，那么给玩家加上一个标签；然后，因为使用了技能，所以这个道具要被清掉。
clear @a[tag=skillSpell1] dye 5 1 {AssSkill:1}
到这里，我们就完成了第一步。接下来是第二部分。
技能事件
从前面的条件看出，我们要对红蓝两队分开讨论（因为我们要知道谁是敌方玩家，故此要分别比对）。每一个队伍中使用了这个技能的玩家，要标记一个不是自己队伍的附近玩家以便进行下一步操作。
execute @a[tag=skillSpell1,team=red] ~ ~ ~ scoreboard players tag @p[r=15,team=!red,m=2] add SkillTag1
execute @a[tag=skillSpell1,team=blue] ~ ~ ~ scoreboard players tag @p[r=15,team=!blue,m=2] add SkillTag1
如果说有符合相应条件的玩家，那么现在就是触发技能的时候了。需要完成的效果是瞬移到对方背后。因此我们需要小小地动一下脑筋，分两步来完成，第一步是直接tp
execute @a[tag=skillSpell1,team=red] ~ ~ ~ tp @s @p[team=!red,tag=SkillTag1]
execute @a[tag=skillSpell1,team=blue] ~ ~ ~ tp @s @p[team=!blue,tag=SkillTag1]
execute @a[tag=SkillTag1] ~ ~ ~ scoreboard players tag @p[r=0,tag=skillSpell1] add Skill1Success
这一步的标记，表示第一步传送成功，如果成功了则执行后续的操作（因为稍微有点多呢）
紧接着是根据视角来向后tp，由于目前MC没有自带以视角建立坐标系的功能，所以要进行简单穷举面向，来实现这个功能。

到这里，我们就实现了TP的功能。实现完功能以后，我们需要清除掉整个事件中使用到的tag。当然了。在清除tag之前，我们先为玩家设定一下技能冷却，假如是15秒，换算成游戏刻则是300。
scoreboard players set @a[tag=skillSpell1] skill1CD 300
然后清tag
scoreboard players tag @a[tag=skillSpell1] remove skillSpell1
scoreboard players tag @a[tag=SkillTag1] remove SkillTag1
scoreboard players tag @a[tag=Skill1Success] remove Skill1Success
至此，第二部分已经完成。
技能冷却、补给
在前面我们已经为玩家设定好了CD时间那么只需要进行计时以及在需要的时间进行补给即可。
scoreboard players remove @a[score_skill1CD_min=0] skill1CD 1
replaceitem entity @a[score_skill1CD_min=0,score_skill1CD=0] slot.hotbar.2 dye 1 5 {AssSkill:1,display:{Name:"§b背刺",Lore:["§a神不知鬼不觉出现在敌人后面！","§c·将该技能置于副手瞬间触发","请勿修改道具快捷键","§c·冷却时间15秒"]},ench:[{id:0,lvl:0}],HideFlags:63}
这就是第三部分的内容，非常简单。但是，如果你是一个细心的玩家，你一定会思考这样一个问题：如果玩家直接丢了技能或者进行了别的错误操作，该怎么办？
那么，你就需要特别处理额外的这些情况，这部分会教你如何锁住技能的位置，一旦发生异常，则会强行重置CD。
# 在正确位置就给tag
scoreboard players tag @a[m=2,score_skill1CD=-1] add withSkill1 {Inventory:[{Slot:2b,tag:{AssSkill:1}}]}
scoreboard players tag @a[m=2,score_skill1CD=-1] add withSkill1 {Inventory:[{Slot:-106b,tag:{AssSkill:1}}]}
# 没有指定的tag就代表不在指定位置，情况异常
clear @a[m=2,score_skill1CD=-1,tag=!withSkill1] dye -1 64 {AssSkill:1}
tellraw @a[m=2,score_skill1CD=-1,tag=!withSkill1] ["[§6提示§r]§b背刺§a道具异常，正在重新计算§b冷却时间§r"]
scoreboard players set @a[m=2,score_skill1CD=-1,tag=!withSkill1] skill1CD 300
scoreboard players tag @a[tag=withSkill1] remove withSkill1
通过这个例子，我们可以发现，其实所谓的技能系统，并不复杂，只要你能够把系统拆分成我所说的这几个部分，并逐一完善，你就能写出很棒的技能系统来。
