银行系统

By MCSugar_cane    2017/11/04

一个功能性的小系统，新加入玩家会成为银行普通用户并获得100的存款，玩家可以提现存款和存入现金。玩家可以通过用10000现金来购买银行付费用户。在玩家死后，银行普通用户会掉落100现金，付费用户只会掉落50现金。如果玩家现金超支（为负数），则系统会自动在存款中扣除超支现金的两倍作为惩罚！

代码适用版本为1.8-1.12.2

整体思路：

要实现存款和体现，需要两个计分板来储存这两个数据，在这里我用cash代表现金、deposit代表存款。首先，判定玩家是否在银行注册了用户，这里的银行用户都加入了YHuser队伍，所以直接用@a[team=!YHuser]就能选择到没有注册用户的玩家。

存款和提现的处理：对于现金满足条件，就直接检测最近玩家的现金（cash）是否达到一定值（满足值），如果达到则减少最近玩家相应现金分值（cash），增加该玩家对应的相应存款（deposit）。因为本系统的现金额是大于等于0的，所以不满足只需要检测玩家现金（cash）分值是否为“0到满足值-1”即可。为什么要是“满足值-1”而不是“满足值”呢，因为MC中计分板是整数，所以如果包含了那个数，玩家现金分数刚好为满足值，那么玩家岂不是既满足了现金满足条件，又满足了现金不满足条件了。其次是这里的判定需要用到scoreboard players test @p cash 满足值 *，因为如果用testfor @p[score_cash_min=满足值]则在多人游戏中游戏会选择最近的符合条件的玩家，而不是最近玩家。

玩家死亡掉落现金其实很简单，就在原有判定死亡的基础上，将死亡玩家的现金（cash）减去100或50。这里的普通用户会有一个ptuser的tag标签，付费用户为ffuser标签。所以分别@a[tag=ptuser&ffuser]就能选中所有的银行用户。

对于现金超支的判定，即现金（cash）小于0（小于等于-1），若玩家cash小于0的时候，用玩家的deposit+=cash两次即可。因为此时玩家的现金（cash）为负数，所以这时的deposit+=cash就等于deopsit-=|cash|；若执行两次，就等于deopsit-=2|cash|。即减去存款值=超支现金x2。


代码：

创建变量：

  1. /scoreboard objectives add cash dummy 现金
  2. /scoreboard objectives add deposit dummy 存款
  3. /scoreboard teams add YHuser
  4. /scoreboard objectives add cashlose deathCount

初始化：[高频循环]

  1. /scoreboard players add @a cash 0
  2. /scoreboard players add @a deposit 0

新人福利：[高频循环]

  1. /scoreboard players add @a[team=!YHuser] deposit 100
  2. /execute @a[team=!YHuser] ~ ~ ~ tellraw @p[r=0] [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"gold","bold":"true"},{"text":" 检测到您还未注册账户，本银行已自动为您注册，并为您预存了100元整存款。","color":"green"}]
  3. /scoreboard players tag @a[team=!YHuser] add ptuser
  4. /scoreboard teams join YHuser @a[team=!YHuser]

银行资质显示：[高频循环]

  1. /execute @a[team=YHuser,tag=ptuser] ~ ~ ~ title @p[r=0] actionbar [{"selector":"@p","color":"dark_green","bold":"true"},{"text":"，您是银行","color":"green","bold":"true"},{"text":"普通用户","color":"gold"},{"text":" | ","color":"aqua","bold":"true"},{"text":"您的当前现金：","color":"green","bold":true},{"score":{"name":"@p","objective":"cash"},"color":"gold","bold":"true"},{"text":" | ","color":"aqua","bold":"true"},{"text":"您的当前存款：","color":"green","bold":true},{"score":{"name":"@p","objective":"deposit"},"color":"gold","bold":"true"}]
  2. /execute @a[team=YHuser,tag=ffuser] ~ ~ ~ title @p[r=0] actionbar [{"selector":"@p","color":"gold","bold":"true"},{"text":"，您是银行","color":"green","bold":"true"},{"text":"付费用户","color":"gold"},{"text":"，尊享消费特权","color":"green","bold":"true"},{"text":" | ","color":"aqua","bold":"true"},{"text":"您的当前现金：","color":"green","bold":true},{"score":{"name":"@p","objective":"cash"},"color":"gold","bold":"true"},{"text":" | ","color":"aqua","bold":"true"},{"text":"您的当前存款：","color":"green","bold":true},{"score":{"name":"@p","objective":"deposit"},"color":"gold","bold":"true"}]


存款与提现：

本部分中条件约制对版本有要求，如游戏版本不支持条件约制，则需要布线来判定，详情见演示地图。

存款：

  1. scoreboard players test @p cash 100 *
  2. scoreboard players remove @p cash 100 （条件约制）
  3. scoreboard players add @p deposit 100 （条件约制）
  4. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"dark_green","bold":"true"},{"text":" 您已成功存款100元","color":"green"}] （条件约制）
  5. scoreboard players test @p cash 0 99
  6. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"dark_green","bold":"true"},{"text":" 您的现金不足","color":"red"}] （条件约制）

提现：

  1. scoreboard players test @p deposit 100 *
  2. scoreboard players remove @p deposit 100 （条件约制）
  3. scoreboard players add @p cash 100 （条件约制）
  4. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"dark_green","bold":"true"},{"text":" 您已成功提现100元","color":"green"}] （条件约制）
  5. scoreboard players test @p deposit 0 99
  6. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"dark_green","bold":"true"},{"text":" 您的存款不足","color":"red"}] （条件约制）


成为付费用户：

  1. scoreboard players test @p cash 10000 *
  2. scoreboard players remove @p cash 10000 （条件约制）
  3. scoreboard players tag @p[tag=ptuser] add ffuser （条件约制）

  5. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"gold","bold":"true"},{"text":" 您已成为银行付费用户！尊享消费特权！","color":"green"}] （条件约制）
  6. scoreboard players test @p cash 0 9999
  7. tellraw @p [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@p","color":"dark_green","bold":"true"},{"text":" 您的现金不足","color":"red"}] （条件约制）


死亡现金掉落：[高频循环]

    银行普通用户：
  1. /scoreboard players remove @a[score_cashlose_min=1,tag=ptuser] cash 100
  2. /execute @a[score_cashlose_min=1,tag=ptuser] ~ ~ ~ tellraw @a [{"text":"[甘小蔗银行]","color":"gold","bold":"true"},{"selector":"@a[score_cashlose_min=1]","color":"dark_green","bold":"true"},{"text":" 死亡掉落了100现金","color":"dark_red"}]
    3. 银行付费用户：
  3. /scoreboard players remove @a[score_cashlose_min=1,tag=ffuser] cash 50
  4. /execute @a[score_cashlose_min=1,tag=ffuser] ~ ~ ~ tellraw @a [{"text":"[甘小蔗银行] ","color":"gold","bold":"true"},{"selector":"@a[score_cashlose_min=1]","color":"gold","bold":"true"},{"text":" 死亡掉落了50现金","color":"dark_red"}]
  5. /scoreboard players reset @a[score_cashlose_min=1] cashlose


现金超支惩罚：[高频循环]
