Add a line between two objects? I have empty1, the empty that fires the bullet(s), and empty2, the empty that is always at the center of the screen. If you are confused about empty2's function, look at this question. On command, I need a line, which is our bullet, to be added. I obviously can't just add a line that starts at empty1 and is endless as that causes many issues. When the command to shoot a bullet is sent, I need a line to be created, starting from empty1, and I need to it to continue towards empty2. In other words, I need a line to be between two objects (for my case, empties). What is the best way to achieve this? Thanks!

EDIT: I prefer that the "line" is an object as I'll be planning to change its color, thickness, etc.
I added these to clarify what I do


You could select one empty, then press ShiftS --> Cursor to selected!


Add a curve (since you can modify it's thickness), press Tab to enter 'edit mode', select one vertex, press ShiftS --> Selection to cursor. Press Tab to exit 'edit mode'


Select the other empty, ShiftS --> Cursor to selected. Then select the curve, press Tab to enter 'edit mode'

select the other vertex, press ShiftS --> selection to cursor


result:
