Not changing value after being set.
Hello,
So, my problem is this: I am accessing a variable from another script, the player can change that variable by input, the problem is for example, I have a class A and anothee one called B, A contains a variable X, B accesse's X from A using, I want B to keep the initial X variable even if it changes in A, is it possible?
public class A : MonoBehaviour {
public GameObject X;
OnMouseDown() {
X = gameObject;
}
}
public class B : MonoBehaviour {
GameObject x;
void update
{
GameObject A0 = GameObject.Find("A's GameObject");
A a = A0.GetComponent<A>();
x=a.X
//Do something with x
}
}
@II_Spoon_II So basically a simple script like that should work. If x is not set already then it will be set otherwise it will remain the same and because you set x in the other script before setting in in the original script then you will surely have the value you need.
public class A : MonoBehaviour {
public GameObject X;
private B other;
void Start() {
other = GetComponent<B>();
}
void OnMouseDown()
{
other.UpdateX(gameObject);
X = gameObject;
}
}
public class B : MonoBehaviour {
public GameObject x;
private bool xRecieved = false;
public void UpdateX(GameObject obj)
{
if (xRecieved == false) {
x = obj;
xRecieved = true;
}
}
}
Hello there,
The way you do it here will always return the CURRENT value of X, not the initial one.
What you want to do instead is have a variable on B (let's call it "initialX"), that gets assigned to X on Start().
Then, as long as you don't change it, that initialX will always be the value that X had at the beginning.
private GameObject initialX = null;
private void Start()
{
GameObject Aobject = GameObject.Find("A's GameObject");
initialX = Aobject.GetComponent<A>().X;
}
Hope that helps!

The problem is initially X is null, the player selects while in game so I don't think Start will be ideal
Since a GameObject is a reference type, the only solution is to have two fields.
public class A : MonoBehaviour
{
private GameObject x ;
public GameObject InitialX
{
get ; private set ;
}
void OnMouseDown()
{
x = gameObject;
if( InitialX == null ) InitialX = gameObject ;
}
}
public class B : MonoBehaviour
{
GameObject x;
void Update()
{
// The following is **not advised at all**
// Calling Find and GetComponent every frame is resources-consuming
GameObject A0 = GameObject.Find("A's GameObject");
A a = A0.GetComponent<A>();
x = a.InitialX ;
//Do something with x
}
}
