    Hi

    Would anyone know how I would create a curved arrow? I am creating a tennis game, when the player clicks on a place where he wants the ball to land, the arrow appears showing the flight path of the ball.

    I hope you understand what I'm getting at? It's probably not a great explanation, but I'd appreciated any help.

    Many Thanks

    Hi Zombee81

    There are different way of approaching this, an efficient one is particle trail and billboards.

    Thus an option would be to create an arrow as a combo of :
    A billboarded sprite for the arrow tip:
    CameraFacingBillboard script from the community
    SpriteRenderer doc

    And a trail renderer for the tail:
    TrailRenderer

    Regarding the shape of the arrow you can go with this excellent tutorial from Catlike coding:
    Curve and spline tutorial

    Finally i have assembled these into an example project (Unity 5.2.1f1) that you can find attached, its itself based on the 2nd example project of the curve & spline tutorial from Catlike coding.

    Screenshot (see attached ArrowExampleProject.unitypackage for full source)

    Have a great day.
