It's hard to tell without knowing more about your game, there are lots of possibilities.
From what I've seen, Bullet is probably not the best choice here.
If the game is grid based, maybe instead of collision detection you should scan the Tilemap, look for the tile with Red arrow in the direction of movement. And then use MoveTo behavior to move to that destination tile. Or something like that.
Or if you want to use Bullet, you can try "System Pick by Overlapping point" event instead "On collision".
