How to connect Scripts and Objects correctly
Hi, this is a very basic Question, because i offen run in this Kind of problem. On one script I can read variables from other scripts and the next time this does not work. So I thought I make an class to store important things where I can access easily from every script, but don't know how to realize it in unity.
The problem I currently have is the game over. I need this information for the player, enemys, score and so on. But I can't access them everywhere the same way and don't know how to get this to work.
Most the time I get the error object reference not set to an instance of an object. But sometimes it just works and this makes it very difficult to find out why it does not work correctly.
Create a script containing static variables ( ex : public static int max_inventory )
Also, in the same script static functions ( ex : public static void addXpPoints () )
Its all about using static variables. You can call anything just by referencing the class name of the script.
Thx, but I found another way to get what I wanted. I use a Script I called Connector.cs bind it to the $$anonymous$$ainCamera and access it then from there. I also use getter and setter method(getHealth(),setHealth()) in this connector script. $$anonymous$$y own Answer is awaiting approval, but should be avaiable in a short time.
I managed it myself by binding a script to the MainCamera. I called it Connector
This is how the Connector.cs looks like using UnityEngine; using System.Collections;
/*
* Script used for sharing Variables between several Scripts
*
*/
public class Connector : MonoBehaviour {
public int playerHealth;
public bool gameOver = false;
public bool isPause = false;
public bool resetPlayerPrefs = false;
// Use this for initialization
void Start () {
if(resetPlayerPrefs){
Debug.Log("Delete PlayerPrefs is Active!");
PlayerPrefs.DeleteAll();
}
}
// Update is called once per frame
void Update () {}
public void setPlayerHealth(int health)
{
playerHealth = health;
}
public int getPlayerHealth()
{
return playerHealth;
}
public void setGameover(bool gameover)
{
gameOver = gameover;
}
public bool getGameover()
{
return gameOver;
}
public void setPause(bool pause)
{
isPause = pause;
}
public bool getPause()
{
return isPause;
}
}
And thats how to access this anywhere in other Scripts:
GameObject ob; //Connector, Top of the Class
In start(){} I add:
ob = GameObject.FindGameObjectWithTag("MainCamera");
And thats how I access Variables:
ob.GetComponent().getPlayerHealth();
I think this Solution is a very clean one. It is possible to access the Variables directly, but i like to use Getter- and Setter-functions.
Now I have cleaned up my Code and don't have the problems with accessing everything from everywhere.
