Hey @Ocir-Tello!
Are you rotating your actor while aiming/ is your projectile always going to be in front of your actor? Or is this a side view.
If it is a former, you can add an arrow component and use it as a spawn point for your projectile. Here’s a great non Epic tutorial that gives an example:
A screenshot explaining how exactly you want this to execute would help pinpoint what exactly you are missing and what to add.
Any additional information you can provide will be a big help in solving your problem!
