I have 3D Spaceship facing forward, and want aiming for shooting to rotate in an axis point, but stopped from shooting behind yourself at camera?

Hello, I am making a rail shooter, and want the space ship to aim at enemies that come towards the screen.
it would rotate the aiming on an axis point with the joystick,
I would want it to be only half a circle tho, so you can’t shoot behind yourself, only forward and sides. the ship will still move in 2D on a 2D plane with the other joystick, so aiming is separate from that.

here is a picture I made with blender that I hope helps to understand:

How could I go about creating this?

Hi @Psyball, I’m guessing U are already rotating your character/pawn using just yaw inputs. You can set limits to any/all the axes (roll, pitch, yaw) by adding a custom Player Camera Manager (set in Ur cusom Player Controller), so they can’t rotate backwards.

Here’s how I’d set up Ur character/pawn, bullet and enemy actors:

Character/pawn actor

  • put a ‘Scene’ component in Ur character/pawn at the point(s) where U’d like to shoot bullets from (the nose, wingtips, etc)
  • when your ‘Fire Weapon’ triggers:
    — ‘Get Forward Vector’ (facing direction) of Ur spaceship
    — ‘Get World Location’ of Ur scene component
    — spawn the bullet actor, feeding in forward vector and location above

Bullet actor

  • maybe use a projectile actor which has convenient and efficient built-in functionality (incl. homing for missiles if U’d like to add special weapons)
  • set it’s travel speed in the component details

Enemy spaceship actor

  • set up collision
  • on the collision event, add logic to destroy itself, or reduce it’s health.

Later on, make the bullets and 'splosions look pretty by adding lights and particles.

I hope this is what U had in mind :slight_smile:
