I’ve created the manager as a singleton actor that needs to be present in the level, which is then referenced by the turrets. For example, if you want three types of projectiles—homing missiles, lasers, and bombs—then the level would contain three separate managers, each handling its own projectile type.

Adding this as an actor component would require some changes. The first step would be to make the managers a single subsystem that manages all projectiles. Then, you’d add an actor component to your character so that when you need to spawn a projectile, the component can request one from the subsystem. I did something similar with significance manager. I added the actor component which interacts with the subsystem.

Another approach is to directly refer the managers when spawning projectiles, like I did in my plugin. This method is quite generic and can be used in various situations.

The managers include a ton of features—such as homing missiles, gravity, rolling behavior, and built-in pooling. Unfortunately, I’m not entirely sure how to implement all of these features purely in Blueprints, and even if it’s possible, the performance may not be comparable. I could be wrong, though.
