Kinoko::Field::ObjectSniper Class Reference

#include <ObjectSniper.hh>

Description

The base class for a manager object which is responsible for synchronizing a set of projectiles and a projectile launcher.

In the base game, this is used for:

  • DS Desert Hills: The sun and FireSnakes
  • GBA Shy Guy Beach: The ship and the bombs Every frame, this class checks if the launcher is ready to spawn a projectile, and it maps between the launcher's current rail point and the corresponding projectile to launch.
