没用，就算没看那个盔甲架也会触发指令
前置：/summon minecraft:armor_stand ~ ~1 ~ {Tags:["tp1"],NoAI:1b,Invulnerable:1b,PersistenceRequired:1b,Silent:1b,NoGravity:1b,Invisible:1,Small:1,NoBasePlate:1,DisabledSlots:2039583,Rotation:[0f],Pose:{Head:[0f,0f,0f],Body:[0f,0f,0f],LeftArm:[0f,0f,0f],RightArm:[0f,0f,0f],LeftLeg:[0f,0f,0f],RightLeg:[0f,0f,0f]}}
循环：execute as @e[tag=tp1] at @s run execute if entity @e[type=minecraft:armor_stand,distance=0..0.5,tag=!tp1,tag=!tp2,tag=!tp3] run particle minecraft:end_rod ~ ~1 ~ .02 .02 .02 .07 2 force @a
循环：execute as @a at @s run tp @e[tag=tp1] ^ ^ ^1
这是问题1，问题2明天回答
不过这个方案有缺点，只能检测前方1格
