灵感来源为一次我在写战利品表时的偶然想法
原理：借助战利品表来生成随机损坏值的工具，来生成随机数。

模块功能

代码解析

战利品表：random.json

函数ran:start 用于建立计分板

函数ran:random 用于产生随机数

tag @s add ran_creating
summon armor_stand ~ -10 ~ {Tags:["ran"]}

summon chest_minecart ~ -10 ~ {LootTable:"ran:random"}
execute positioned ~ -10 ~ run kill @e[sort=nearest,type=chest_minecart,limit=1]
#激活战利品表
scoreboard players set @e[tag=ran] ran 1024
execute positioned ~ -10 ~ as @e[sort=nearest,type=item,nbt={Item:{id:"minecraft:diamond_sword"}},limit=3] store result score @s ran run data get entity @s Item.tag.Damage
execute positioned ~ -10 ~ as @e[sort=nearest,type=item,nbt={Item:{id:"minecraft:diamond_sword"}},limit=1] store success entity @s Item.Count byte 0 run scoreboard players operation @e[tag=ran_creating] ran = @s ran
scoreboard players operation @e[tag=ran_creating] ran *= @e[scores={ran=1024}] ran
execute positioned ~ -10 ~ as @e[sort=nearest,type=item,nbt={Item:{id:"minecraft:diamond_sword"}},limit=1] store success entity @s Item.Count byte 0 run scoreboard players operation @e[tag=ran_creating] ran += @s ran
scoreboard players operation @e[tag=ran_creating] ran *= @e[scores={ran=1024}] ran
execute positioned ~ -10 ~ as @e[sort=nearest,type=item,nbt={Item:{id:"minecraft:diamond_sword"}},limit=1] store success entity @s Item.Count byte 0 run scoreboard players operation @e[tag=ran_creating] ran += @s ran
#采用1024进制（？？？），随机生成一个0~1073741823的随机数
scoreboard players operation @e[tag=ran_creating] ran += @e[tag=ran_creating] ran
execute positioned ~ -10 ~ as @e[sort=nearest,type=item,nbt={Item:{id:"minecraft:stone"}},limit=1,distance=..1] store success entity @s Item.Count byte 0 run scoreboard players add @e[tag=ran_creating] ran 1
#将最初的随机数翻倍，并随机决定是否加上1，得到0~2147483647之间的随机数

scoreboard players operation @s ran_delta = @s ran_max
scoreboard players operation @s ran_delta -= @s ran_min
scoreboard players add @s ran_delta 1
#确定随机数的生成范围
scoreboard players set @e[tag=ran,limit=1] ran 2147483647
scoreboard players operation @e[tag=ran,limit=1] ran /= @e[tag=ran_creating] ran_delta
scoreboard players operation @e[tag=ran_creating] ran /= @e[tag=ran,limit=1] ran
#将2147483647分成数个组，根据所得随机数落在哪一个组来决定随机数的大小
scoreboard players operation @s ran += @s ran_min
#得到指定范围内的随机数

execute positioned ~ -10 ~ run kill @e[sort=nearest,limit=1,type=armor_stand,tag=ran]
tag @s remove ran_creating

execute if score @s ran > @s ran_max run function ran:random
#检查随机数是否落在指定范围内，若不是则重新生成随机数

函数ran:setweight 用于生成随机数组

函数ran:weight 用于随机选取加权数组并生成随机数

函数ran:inputfunction1 用于辅助ran:weight函数选取合适的数组

函数ran:randomdebug 用于分析是否能将ran:random在某个实体上应用

函数ran:weightdebug 用于检测是否能将ran:weight应用在目标实体上

函数ran:inputfunction2 用于协助ran:weightdebug 来检查每个随机数组的数值

scoreboard players set @e[type=armor_stand,tag=ran_weighting,limit=1] ran_delta 0

想说的话

其实如果能看懂我的这个方法的大体思路之后，或许就可以不使用我的模块，自制战利品表来生成随机数。自制战利品表可以通过掉落的概率很轻松地控制每个随机数的可能性大小。但我之所以要把这个作品放出来，也是想给大家提供一个新思路（因为暂未看到bbs内有借助战利品表做随机数的先例（至少我没发现））。这也是我的第一个作品吧，希望能得到大家的认可。不会用图床，图片只能用附件来上传了。

啊哈哈哈哈学到了！

set_damage可以，但是没必要。用set_attribute可以设置浮点数的范围内的随机数，比整数肯定更好使，不用做进制转换。

目前深入研究cb一年左右，对一些东西了解的还不是太多。不过感谢大佬指教，确实没想到这个时候float数据能起到这种作用
~~话说这是几个月之前的帖子，当时没人回复，要不是最近莫名其妙被挖出来，我都忘了发过这个帖子了~~
