二进制逻辑¶
二进制（Binary）在命令系统里最实用的价值，是把“线性枚举”压缩成“按位拆解”，显著减少命令量。
位权回顾¶
| 位 | 值 |
|---|---|
| \(2^0\) | 1 |
| \(2^1\) | 2 |
| \(2^2\) | 4 |
| \(2^3\) | 8 |
| \(2^4\) | 16 |
| \(2^5\) | 32 |
| \(2^6\) | 64 |
例如1101_2=8+4+1=13。
商店示例(1到64)¶
BP/functions/wiki/binary/shop.mcfunction
execute as @a[hasitem={item=bread,quantity=64..}] run scoreboard players add @s wiki:money 64
execute as @a[hasitem={item=bread,quantity=64..}] run clear @s bread 0 64
execute as @a[hasitem={item=bread,quantity=32..}] run scoreboard players add @s wiki:money 32
execute as @a[hasitem={item=bread,quantity=32..}] run clear @s bread 0 32
execute as @a[hasitem={item=bread,quantity=16..}] run scoreboard players add @s wiki:money 16
execute as @a[hasitem={item=bread,quantity=16..}] run clear @s bread 0 16
execute as @a[hasitem={item=bread,quantity=8..}] run scoreboard players add @s wiki:money 8
execute as @a[hasitem={item=bread,quantity=8..}] run clear @s bread 0 8
execute as @a[hasitem={item=bread,quantity=4..}] run scoreboard players add @s wiki:money 4
execute as @a[hasitem={item=bread,quantity=4..}] run clear @s bread 0 4
execute as @a[hasitem={item=bread,quantity=2..}] run scoreboard players add @s wiki:money 2
execute as @a[hasitem={item=bread,quantity=2..}] run clear @s bread 0 2
execute as @a[hasitem={item=bread,quantity=1..}] run scoreboard players add @s wiki:money 1
execute as @a[hasitem={item=bread,quantity=1..}] run clear @s bread 0 1
为什么快
玩家有50个面包时，系统会按32→16→2拆解，只需命中3档，而不是从1数到50。
进阶方向¶
- 用二分思路获取坐标整数分数。
- 与分叉执行结合生成复杂结构。
