When clicking Fire the Debug Sphere gets Drawn and then The Turret will rotate to wherever the mouse was first captured when entering play mode.
I can work around this by selecting “Do Not Lock” in the Default Viewport Mouse Lock Mode but, I don’t recall seeing this mentioned in any videos so far.
No the turret will turn and aim as expected but, as soon as Fire is pressed it will fire and then the Turret immediately snaps to wherever the mouse cursor was when you first clicked on the play screen.
For example:
Press play and the game starts you can still see the mouse cursor.
Move the mouse so that the turret points to the left.
Click the mouse and the cursor disappears as the play screen captures the mouse.
Now play the game every time you fire the turret will now snap to the left after firing.
Like I mentioned setting “Do Not Lock” and everything works correctly.
