    use vectors.

    (world_mouse_position - world_gun_pivot_position).normalize() - this will be direction of gun orientation in world space.
    where world_gun_pivot_position is point where gun attached. in world space. it should be like local_gun_pivot_position + world_vehicle_position.

    then convert direction to rotation using one of MakeRotFrom* functions, depending on your coordinate system.
    and set gun rotation in world space.

    to use local position, relative to vehicle position, simply subtract vehicle position from it:
    local_mouse_position = world_mouse_position - world_vehicle_position;

    This BP I'm using is working great, but there is a noticeable snapping with aiming directly above. I'm hoping to have version that rotates as seamless as possible.

    Rotating the arrow towards it. I found a solution, but it is a bit limited. When the arrow is close to 90 degrees aiming above the character its snaps about 5 degrees to the opposite side. I'm at work atm, but I can follow up later with a screenshot of my blueprints, the video I followed, and the results.

    Hi, are you having trouble finding the exact cursor location on the character's movement plane, or with rotating the arrow towards it?

    Sidescroller with asset aiming towards mouse position

    Hello! I'm trying to build a sidescroller that moves a character to the right of the screen and left, but most importantly an arrow that aim towards the mouse cursor's position on the screen. The best example I can think of is Metal Slug's tank:

    I've made a couple of attempts to best replicate this effects but to no avail.


    The first one doesn't rotate around the characters at all while the second only works in a limited range

    Any help would be greatly appreciated! I'll continue to find to find a solution!
Working...
