How to pass a variable from one script to another C # Unity 2D?

Question

For example, I have a variable (public static float currentLife) in the script "HealthBarGUI1", and I want to use this variable in another script. How to pass a variable from one script to another C # Unity 2D?

Answer 1

You can do something like this because currentLife is more associated with the player than with gui:

class Player {

  private int currentLife = 100;

  public int CurrentLife {
    get { return currentLife; }
    set { currentLife = value; }
  }

}

And your HealthBar can access currentLife in two ways.

1) Use a public variable from the GameObject type, where you simply drag and drop your Player from the hierarchy into the new field of your script component in the inspector.

class HealthBarGUI1 {

  public GameObject player;
  private Player playerScript;

  void Start() {
    playerScript = (Player)player.GetComponent(typeof(Player)); 
    Debug.Log(playerscript.CurrentLife);
  }

}

2) find. , , .

class HealthBarGUI1 {

  private Player player;

  void Start() {
    player = (Player)GameObject.Find("NameOfYourPlayerObject").GetComponent(typeof(Player));
    Debug.Log(player.CurrentLife);
  }

}

currentLife . , currentLife. , , ?

//Drag your object that includes the HealthBarGUI1 script to yourSceondObject place in the inspector.

public GameObject yourSecondObject;
