How to have player be moved by motion vector when their projectile hits a block?

I am making a grappling hook, and the player will move towards where the projectile hits. However, the motion vector block doesn't move the player at all, despite the block being run multiple times to ensure that the motion vector isn't being run for just one tick. Does anyone know why the motion vector block doesn't seem to work with the Bullet hits Block trigger? (The player can be targeted with this trigger)
