二分法商店(Bug已修复)

以下命令方块儿全部设定为无条件

execute @a ~~~ scoreboard players operation @s 金币2 =@s金币

execute @a[scores={价格=1..}] ~~~ scoreboard players operation @s 金币2 -=@s 价格

title @a[scores={金币2=..-1,价格=0..}] title §l§c金币不足!

title @a[scores={金币2=0..,价格=0..}] title §l§a购买成功!

execute @a[scores={金币2=0..,价格=0..}] ~~~ scoreboard players operation @s 金币 -= @s 价格

execute @a[scores={金币2=0..,价格=0..}] ~~~ clone ~~-3~ ~~-3~ ~~1~

execute @a[scores={金币2=0..,价格=0..}] ~~~ setblock ~~1~ air 0 destroy

kill @e[type=item,name=“木桶”]

execute @a[scores={金币2=0..,价格=0..}] ~~~ title @s subtitle §b @e[type=item,dy=2,c=1] §f已放入您的背包

execute @a[scores={金币2=0..,价格=0..}] ~~~ playsound random.levelup @s

scoreboard players reset @a 价格

下面这条指令是商店端，可以无限复制，放到商店中

scoreboard players set @p[dy=2] 价格 550
