Projectiles not facing the correct direction

So, as can be seen in the video, I have a character able to shoot, and charge, projectiles. The character is connected to a spline for 2d style movement with the ability to go around corners, as well as having some code to make turning around instantaneous.

While on the X Axis of the spline, the Projectiles fire and rotate properly, however as soon as i begin to move around the corner they stop working properly for firing to the left of the screen.

Currently the meshes are set up so the projectile meshes are parented to a sphere collider, the meshes are set to relative rotation and the sphere collider to world, best I’ve been able to figure out is that for some reason, my projectiles are being tied to the camera instead of actually rotating in the world other than velocity. The reason I think this is because if i disable the code that keeps the camera on the same side of the player, the projectiles fire in any direction just fine. I’m debating about just buying a camera system from the marketplace, but want to try to get this working without having to spend money which I currently don’t have first.

In the long run I will need to figure out a way to set my camera to stay within the bounds of the level, but for now, this is a higher priority to me.

I have tried putting the same 180 input into the Z of my spawn actor rotator for when the player faces left, but it doesn’t work.

I managed to mostly fix the rotation issue by connecting my projectiles to my level spline, this means players could shoot around corners technically as their projectile will follow the level spline. However, those corners are the current issue, I need the projectile’s velocity to follow around the curve, but it currently doesn’t.

I tried multiplying the spline rotation into the velocity(this is how I fixed the rotation of the projectiles) and then setting the velocity to that, but that just results in errors like “setting none.node” and such.

There should’nt be a Scene Component in your projectile class. The Root should be the collision, then the meshes/FX are children.

I do have it set up that way now, however there’s still the issue of my projectile’s velocity not rotating to follow the spline the way the player does. I wanted to make curved 2.5D levels, so I need the projectiles to curve so they still hit enemies.

I’ve figured out a curve that works with shooting the projectile straight forward, it seems the minimum for a comfortable distance, IMO, is a spline radius of 5,000, just in case this is helpful for anyone who finds this thread and wants to make a spline linked sidescroller with curves and projectiles.

I sadly still have no idea how to make the projectiles follow the spline both with rotation and velocity, small 90 degree curves just result in projectiles stopping their movement.
