『原理』
第1遍n叉生成实体绳结， 第2遍n叉生成筛选（遍历位置为空气）实体绳结，根据第2遍n差遍历的位置，在某个范围内存在绳结这个实体，则视角采取玩家，采取第1遍历n差，再次遍历出来的位置，执行一定范围内的清除实体-------这一部就用很简单的一种判定实体存不存在的方式，实现限定粒子的生成
鱼钩在非法位置纠正具有延迟性
绳结的不稳定性
『思路』
存在鱼钩时，以该鱼钩为中心，距离自身最近的两个实体标上标签
纠正鱼钩的视角并将其传送到非法位置，视角与玩家相反
以玩家为中心，往前提n格（N为n差遍历的最大长度），实际出现在玩家的视角正前方，执行n叉树遍历位置并执行命令生成绳结实体
同样以玩家为中心往前提，n+0.2~0.25格，执行nx并筛选非空气位置执行生成绳结
*同样以玩家为中心往前提，N+0.2~0.25格，执行n差并筛选一定范围内存在两个绳结的位置，并以该位置为中心，选择离其最近的一个绳结，以玩家为视角，往前tp true一定距离(根据不稳定性,如果不完整方块允许通过则消失,是为通路,如果不允许通过则不消失，视为断路)

以绳结这个实体为中心执行粒子
以绳结这个实体为中心执行范围伤害
（根据绳结的不稳定性，当其受到一点伤害的时候会自动消失）

『测试区命令』
（没有特殊标记的话全部是脉冲红色条件，主要是测试鱼钩的延迟性以及绳结这个实体的不稳定性，跟视频主题毫无关联）
/summon leash_knot ~~1~
damage @e[type=leash_knot] 1
/execute as@e[type=leash_knot] at@s run tp @s ~~~-1 true
execute as@e[type=fishing_hook] at@s run tp @s ~~~40
execute as@e[type=fishing_hook] run say 1（连锁无条件）
*小贴士:录制的时候发现网页的某些光影会导致一些粒子效果直接失效！建议各位玩家在进行测试的时候，尽量避免使用网易的光影，因为到时候想我一样摸不着头脑
