Detect if particle reaches targeted block

[Hackusater]

Wondering if there is a way to detect when a particle created from DrawLine (sk dragon) reaches targeted-block:

command /test:
    trigger:
        make the player shoot an arrow at speed 1000
        loop 100 times:
            wait 1 tick
            #if particle hasn't reached targeted block/arrow:
                drawLine particle smoke, XYZ 0, 0, 0, center player, target location of target block, id "%player%-%loop-number%", rainbowMode false, solid false, density 2, length 0, zigZag count 0, height 0, visibleRange 100, displacementXYZ 0, 0, 0, pulseDelay 1
            else:
                exit 1 loop

If not is there a way to check if it reaches the arrow?

this should work

command /test:
    trigger:
        make the player shoot an arrow at speed 1000
        set {_loc} to location of target block
        if {_loc} is set:
            set {_density} to 10 #amount of particles at 1 block distance
            set {_time} to 1 tick #time between every particle getting spawned this is difficult to get correctly
            set {_dis} to distance between {_loc} and player
            set {_calc} to rounded ({_dis} * {_density})
            set {_incx} to (x-coord of {_loc} - x-coord of location of player) / {_calc}
            set {_incy} to (y-coord of {_loc} - y-coord of location of player) / {_calc}
            set {_incz} to (z-coord of {_loc} - z-coord of location of player) / {_calc}
            set {_loc2} to location of player
            loop {_calc} times:
                add {_incx} to x-coord of {_loc2}
                add {_incy} to y-coord of {_loc2}
                add {_incz} to z-coord of {_loc2}
                drawDot particle smoke, XYZ 0, 0, 0, center {_loc2}, rainbowMode false, visibleRange 100
                wait {_time}
            broadcast "HIT!"

It works but how do i make it move fasted and how do i make it more than 1 particle so it creates a full line from me to the targeted block
