Singleton - Coding Design Pattern Singleton = There can only be one of it’s type, can be accessed from anywhere. Examples of Singletons: GameManager, UIManager, AIManager, MusicManager, LocalisationManager, … “In software engineering, the singleton pattern is a software design pattern that restricts the instantiation of a class to one "single" instance. This is useful when exactly one object is needed to coordinate actions across the system. The term comes from the mathematical concept of a singleton.”

Serialization of Data Savable Datatypes: Int, Float, String Vector3 cannot be saved  Vector3 = 3 x Float (Pos X, Pos Y, Pos Z) Enums cannot be saved  Enum = Int

Saving PlayerPrefs.SetFloat("PlayerPosX", transform.position.x); PlayerPrefs.SetFloat("PlayerPosY", transform.position.y); PlayerPrefs.SetFloat("PlayerPosZ", transform.position.z); PlayerPrefs.Save();

Loading float playerPosX = PlayerPrefs.GetFloat("PlayerPosX"); float playerPosY = PlayerPrefs.GetFloat("PlayerPosY"); float playerPosZ = PlayerPrefs.GetFloat("PlayerPosZ"); transform.position = new Vector3(playerPosX, playerPosY, playerPosZ);

Checkpoint system OnTriggerEnter  Save Data OnDeath  Load Data from Last Checkpoint
