The particle accelerator controller is the entry point for particles. Items inserted into this block are turned into particles. Collision results can be collected from the output slot.
A straight guide ring needs to be placed right behind the controller, facing to the side, with visuals aligning correctly. Any item can be inserted into the controller to be used as a particle.
Once inserted, the particle travels along a route defined by the guide rings.
For detailed information on particle acceleration mechanics, see the particle accelerator guide.
