How to make a turret on a vehicle to always be align at the crosshair?

I been trying to figure out how to make a turret from a vehicle align to the crosshair and i been having difficulty

this what i’m trying to do make the turret always look at the crosshair, I’m new to this and i haven’t found any tutorials on this

I’ll give it a shot at this. If I was trying to do that, I would convert the crosshair from 2d space to 3d space (the crossair points at the infinity from the camera).
After you have that point you have a direction vector you can use to rotate the cannon.

You would have to point the cannon to:
Cam pos + cam dir * big number

Does this make any sense? Maybe that math is all wrong…

i think i got it to work i use this blueprint

and use this one to lock the mouse on the center

now the problem is that when i posses the pawn of the helicopter it no longer tracks the mouse position
